This document summarizes a presentation made to the Imported Water Committee on September 26, 2013 regarding options for addressing water supply reliability and ecosystem restoration in the Sacramento-San Joaquin River Delta. Four alternatives were analyzed: the BDCP proposed action with a 9,000 cfs north Delta conveyance; a 6,000 cfs alternative; a 3,000 cfs alternative; and relying solely on existing south Delta diversions. The 9,000 cfs and 6,000 cfs options were found to provide greater water exports than the other options. However, uncertainties remained around the operating scenarios that would be used when project operations begin. A decision tree process was proposed to help determine appropriate outflow criteria as more data is collected through studies and adaptive

The Alameda County Water District provides water to over 330,000 people. It relies on state water projects, the San Francisco Public Utilities Commission, and local watersheds for its supply. The District is committed to fiscal responsibility and has invested in conservation, water storage, desalination, and recycled water to reduce reliance on imported supplies. For the Bay Delta Conservation Plan to be considered a viable investment, its costs and benefits for different alternatives must be quantified and uncertainties identified. The plan must also integrate with local water management and meet agencies' needs over the long-term.
This summarizes a study that analyzed the impact of residential irrigation audits on water conservation in Colorado. Over 2,000 homeowners participated in the Slow the Flow Colorado program between 2007-2012. Water use data from before and after the audits was analyzed to determine the effects. On average, water savings were 5,000 gallons per participant in the first year after the audit. However, savings varied significantly in subsequent years, suggesting audits may not provide robust long-term benefits. The study sought to understand factors contributing to water use and adequacy of irrigation.
This document summarizes the energy utility perspective on water and energy in California. It discusses how water represents nearly 20% of the state's electricity consumption and how energy costs are a major portion of water agency budgets. It also outlines California policies aimed at reducing greenhouse gas emissions through water and energy savings. The document describes Southern California Edison's initiatives to identify cost-effective water and energy efficiency opportunities through programs like leak detection, pump testing, and demand response. It emphasizes the importance of continued collaboration between energy and water entities to achieve shared objectives around safety, reliability, affordability, and addressing infrastructure and environmental challenges.
The document summarizes a presentation about the Pure Water program in San Diego. It discusses how the program will provide over 1/3 of the city's water supply through an advanced water purification process. It will treat wastewater from three plants and deliver it to local reservoirs by 2035. This creates a sustainable local water source and reduces reliance on imported water, whose costs have risen significantly. The program is supported by officials, environmental groups, and businesses as a cost-effective water solution for San Diego.
California faces ongoing water challenges including drought, population growth, and climate change. AB 1881 is California's Model Water Efficient Landscape Ordinance that aims to increase water use efficiency in new and existing landscapes through requirements, plan checks, audits, and penalties. The ordinance requires appropriate irrigation technology and design standards that use a water budget approach and address issues like distribution uniformity to reduce water use. GIS, GPS, and satellite imagery can help validate irrigation efficiency and estimate landscape water needs. Developing alternative water supplies will also help ease stressed water resources.
This presentation discusses California's Sustainable Groundwater Management Act (SGMA) and its implications for cities. It provides background on groundwater basin management, including considerations like land use, water rights, and environmental factors. It describes provisions of SGMA that require formation of Groundwater Sustainability Agencies and adoption of Groundwater Sustainability Plans by 2020 for non-adjudicated basins. Cities affected should engage in the local agency and help manage water demand through policies like efficient land development standards and stormwater capture requirements.
Assessing water supply coverage and water lossesAlexander Decker
This document discusses a study assessing water supply coverage and water losses in Axum town, Ethiopia. The study found that the average daily per capita water consumption was 12.8 liters/person/day, below the basic standard of 20 liters/person/day. Approximately 75% of the population received less than this basic level. The total water loss from the system was 39.1% of input volume. Meter under-registration accounted for 8.84% of losses. Performance indicators showed infrastructure leakage was 1.47 times higher than the unavoidable level, indicating potential for reducing losses. The study aims to identify water loss issues and develop strategies to significantly reduce losses.
The document discusses ETwater, a company that provides landscape irrigation management technology. It describes how ETwater systems work by collecting local weather data, calculating daily watering needs based on evapotranspiration rates, and communicating schedules to smart controllers. The system can reduce water use by 20-40% while improving plant health. A case study shows a Denver campus reduced its water consumption by 37% and water bill by 64% after installing ETwater controllers. The document also outlines barriers to adoption and incentives for using smart irrigation technologies.
This document provides an overview of water loss control and effective utility management. It discusses setting strategic planning goals and objectives related to non-revenue water management. These include being financially viable, optimizing resources, providing quality service, prioritizing asset management, reporting key performance indicators, and encouraging team ownership. The document also covers water loss control drivers like drought, public trust, economics, and regulations. States are increasingly requiring water loss reporting and moving away from percentage-based performance targets. Finally, it presents a model for implementing a statewide water loss management program over multiple phases and years to improve data validity and water loss performance.
The document discusses the transfer of water and sewer utility regulation in Texas from the Texas Commission on Environmental Quality (TCEQ) to the Public Utility Commission of Texas (PUC) in 2013-2015. It outlines the PUC's mission and provides details on the new regulatory classifications and requirements for investor-owned utilities under the PUC, including more stringent filing requirements for larger Class A utilities. It also notes trends in the regulated water/sewer industry around infrastructure needs, sales of utilities, and conservation rate structures.
This document analyzes water usage in multi-unit complexes (MUCs) in Saskatoon. It finds that high-rise MUCs have seen decreasing water usage while low-rise usage first increased and then decreased. MUCs with fewer units tend to use more water per unit. Areas with many MUCs do not necessarily have high per-unit usage. Retrofitting MUCs to reduce usage can be cost-effective. Surveys found MUCs do not prioritize conservation but open to initiatives. Partnering with other groups on rebates could incentivize retrofitting and reduce water usage.

The document summarizes Austin's Water Forward plan to ensure reliable water supply for the growing population. It discusses Austin's current water sources, the historic drought, and recommends a hybrid portfolio approach. This includes maximizing conservation, local sources, and reliability through strategies like aquifer storage/recovery, brackish desalination, reuse expansion, and indirect potable reuse. The plan estimates costs and yields through 2040 and outlines next steps like developing codes/incentives and starting an aquifer storage pilot.
The presentation provides an update on drought conditions and response activities in California. It discusses declining water usage, hotter temperatures compared to previous years, compliance with mandatory conservation standards requiring a 25% reduction in water use, and updates to the state's model landscape ordinance to increase water efficiency and limit turf areas. Key points include June 2015 water use being 26% lower than June 2013, local reservoir storage being at 36% of capacity, and the updated ordinance expected to reduce water use in new homes by 20% and commercial landscapes by 35%.

The committee also supported right-sizing conveyance facilities to match demand forecasts and financial commitments, and ensuring the State Water Project remains a publicly owned resource.
Water Quality and Urban Wastewater Management in ChinaJulian Wong
1) Water pollution is a major problem in China, with over half of rivers in northern China and over 70% in southern China rated as heavily polluted.
2) Domestic, industrial, and agricultural use all contribute to water pollution, with industry being the largest polluter.
3) China's urban wastewater treatment system is struggling with underutilized treatment plants, lack of funding for operations and maintenance, and no integration between drainage and treatment systems.
4) Improving performance will require setting enforceable but transitional standards, integrated management of drainage and treatment, private sector participation, and higher water tariffs.
Urban Public Policy and Sustainability: Policy recommendation for the City of...Vanessa Davis
This presentation represents a segment of a group project in a capstone course at Arizona State University on "Urban Public Policy and Sustainability".
Our group was tasked with working with the City of Mesa to identify and research an urban planning policy that could be improved to support a more sustainable trajectory. The final outcome was a policy recommendation delivered to the city and presented to a mock city council. (While we did not present to the actual City Council for Mesa, our "mock council" participants included the Mayor of Mesa, a City Council Member from Tempe and a few other well qualified judges.)
Our group's policy recommendation was concerned with decreasing wastewater for sustainable development via suggested policy changes concerning development impact fees.
The document provides an update on water supply conditions and drought response activities from Dana Friehauf, Water Resources Manager. It includes information on precipitation levels in the Northern Sierra being at 95% of normal, snowpack levels being at 95% of normal, storage levels in Lake Oroville being at 51% of capacity and 74% of average, cumulative potable water use from June 2015-January 2016 being 23% lower than 2013, the outlook for March-May precipitation, an extension and potential adjustments to the State Water Resources Control Board's emergency regulation requiring at least 8% conservation through October 2016, and a new local drought-resilient supply credit as part of the regulation.
Most communities base water connection charges solely on water meter size, which fails to correlate strongly with actual water use. A few communities use multi-factor connection charges that consider lot size, landscaping type, and fixture efficiency to better allocate costs proportionate to predicted water demand. Case studies in Colorado highlight how these charges can incentivize more water-efficient development and avoid infrastructure costs. The report recommends utilities consider refined, multi-factor connection charges to encourage water conservation and development equity.
This document summarizes a stakeholder process in Connecticut to develop standards for low impact development (LID) and stormwater management. It involved:
- Gathering input from other states and stakeholders on alternative approaches
- Workshops to identify and debate alternatives, applying decision criteria and selecting preferred options
- Consensus on incorporating LID guidance and performance standards into stormwater permits, with adjusted standards for sensitive areas.

This document summarizes a report on water use efficiency efforts among water suppliers in Washington state since the adoption of the state's Water Use Efficiency rule in 2007. The report found that most water suppliers have taken significant actions to improve efficiency, such as repairing leaks, implementing conservation rates, installing meters, and setting conservation goals. It also provides data showing progress in specific areas like leakage rates and adoption of efficiency measures. The document aims to establish a baseline for measuring continued progress in water efficiency.
The document discusses a Clean Water Optimization Tool being developed by the Center for Watershed Protection to help municipalities develop cost-effective strategies for meeting water quality goals like the Chesapeake Bay Total Maximum Daily Load. The tool will evaluate practices like bioretention, permeable pavement, and land conservation. It will recommend strategies based on minimizing costs per pound of nutrient or sediment reduced. The tool is being piloted in Maryland's Eastern Shore and will incorporate local data on practice costs and effectiveness.
Lessons learned from green infrastructure project experience in developing co...U.S. Water Alliance
Seattle's decade of experience installing Green Infrastructure (GI) projects has provided a substantial knowledge base. Two key areas of growth will be discussed: 1) Key policy issues in the development of the Seattle's Stormwater Code requirement for use of GI to the “maximum extent feasible” for projects on private property and right-of-way, and 2) public engagement success, failures, and proposed approach in moving forward in installing GI in public and private places, including a look at using GI to assist with combined sewer overflows.
This document discusses the benefits of an integrated planning approach for managing wet weather obligations in Euclid, Ohio. It provides examples from other cities that implemented integrated plans through negotiations with EPA to refine consent decrees, reduce costs by over $100 million in some cases, and prioritize green infrastructure. The document recommends Euclid develop an integrated plan to evaluate control levels, affordability, potential cost savings through regionalization and optimized controls, and inclusion of green infrastructure. It identifies initial issues with Euclid's plan and opportunities through an integrated approach.
This document analyzes and evaluates Minnesota drainage law. It outlines the project purpose of legally analyzing drainage laws to balance costs, benefits, and environmental impacts while protecting property rights. It then describes the legal analysis and critical issues, such as conservation drainage and updating how benefits and damages are determined. Several demonstration scenarios are presented, including a scenario combining conservation and drainage improvements in a rural agricultural area. The document concludes with recommendations related to providing drainage authorities more tools and resources for watershed planning and projects with integrated benefits.
The overall goal of this project was to develop an implementation framework for an offsite BMP program
to maximize the environmental and economic effectiveness with which the City of Wichita meets its
NPDES stormwater permitting requirements to ultimately improve water quality in the Little Ark and
Arkansas Rivers. This program aims to integrate watershed stakholders across sociopolitical bounds and
provide a sustainable funding mechanism to implement and maintain water quality practices in the rural
landscape, a critical need as watershed managers struggle to meet water quality targets (e.g., TMDLs).
Based on dialogue between stakeholders representing the watershed’s agricultural (represented by the
Little Ark Watershed Restoration And Protection Strategy program, or WRAPS) and urban (represented by
the City of Wichita’s Stormwater Advisory Board and City officials) communities and the Kansas
Department of Health and Environment (KDHE), which administers TMDLs and water quality permits, the
program works to optimize the placement of BMPs within the watershed for maximum water quality
benefit of the integrated system. Rural management practices tend to be less costly, thereby enabling
greater pollutant load reduction per dollar spent on BMPs in rural versus urban areas. For this reason, net
costs to urban developments participating in the offsite program should be significantly less than if
traditional urban water quality control practices were installed and maintained. A program framework was
developed in which a “sediment credit” fee is paid annually by urban developments participating in the
program to finance implementation and maintenance of offsite BMPs as facilitated through the Little
Arkansas WRAPS program. Adoption of this offsite program is anticipated to lead to greater reductions in
sediment (and other pollutant) loads leaving the watershed than could be achieved through conventional
implementation of BMPs within urban bounds to meet MS4 permit requirements. The program is currently
in its first year of implementation.
CCW Conference: Cost effective practices for clean waterClean Water
The document summarizes cost effective practices for clean water based on a study of the James River Basin in Virginia. It finds that removing illicit discharges from storm sewer systems, such as sewer repairs and eliminating cross connections, is among the most cost effective ways to reduce nitrogen, phosphorus, and sediment levels. Urban stream restoration is also highly cost effective for sediment removal. Initial estimates found addressing stormwater pollution in Richmond could cost $305 million using older practices, but improving identification and removal of illicit discharges could lower the cost to $84-100 million. Proper identification and removal of illicit discharges is an important yet overlooked method for nutrient management that governments should receive credit for.
This document discusses plumbing products and their contribution to water conservation. It begins with an overview of continuing education credits for architects who take the course. It then outlines the learning objectives which are to understand water supply and demand, conservation benefits, specifying water-efficient plumbing products, and their impact on green buildings. The agenda covers perspectives on water conservation, supply and demand, benefits of conservation, indoor water efficient options, and green buildings.

This research report examines issues and best practices related to sustainable water management in Canadian municipalities. Key issues discussed include environmental concerns like water quantity and quality, economic challenges like infrastructure deficits, and regulatory issues such as changing requirements. The report also explores municipal planning approaches, governance and management practices, and operational technologies. Sustainable water management aims to account for ecosystem needs through reduced consumption, no increased supply, and returning treated water to support a healthy environment and potential reuse. Moving fully to sustainability requires higher initial costs but may reduce long-term risks from issues like climate change. Overall the report provides an overview of current challenges and opportunities for Canadian municipalities to improve water management.
The document discusses the sewer collection system master planning process for the City of Bend, Oregon. It describes:
- Bend's sewer collection system includes 430 miles of sewer mains and over 90 pumping stations that collect over 6 million gallons per day.
- The original master plan faced challenges and capacity issues. A Sewer Infrastructure Advisory Group (SIAG) was formed, consisting of 17 citizen members, to advise on developing an affordable and flexible plan.
- The SIAG was given an expanded role compared to traditional committees, including involvement in decision making. They helped evaluate thousands of potential solutions using an optimization model to identify lowest cost options providing capacity.

This event was hosted online on Aug 5, 2020 by the National Wildlife Federation, Sierra Club (Lone Star Chapter), Bayou City Waterkeeper, and Galveston Bay Foundation.
This webinar provides an in-depth introduction to the 2020 Texas Water Conservation Scorecard. The only effort of its kind in Texas, the Scorecard offers an extraordinarily detailed analysis of water conservation efforts at over 350 Texas water utilities. Jennifer Walker, Deputy Director of the Texas Coast and Water Program at the National Wildlife Federation leads the webinar, along with Ken Kramer, Water Resources Chair at the Lone Star Chapter of the Sierra, and Meghan Bock, Senior Business Analyst at AIQUEOUS.
An initiative of the Texas Living Waters Project, the Scorecard evaluates each utility on a range of criteria including compliance with conservation planning and reporting requirements, its record on water loss and meeting targets for water use reduction, outdoor watering limits, and rate-based incentives for efficient use of water.
Taken in conjunction with the 2016 report, the 2020 Scorecard reveals many utilities are not taking serious actions to advance water conservation.
For more information on the Scorecard’s methodology, results, and recommendations, take a look at the Scorecard website at texaswaterconservationscorecard.org. The interactive site allows users to quickly identify individual utilities’ scores and analysis.
This document summarizes the requirements for developing a water conservation plan in Texas. Municipalities serving 3,300 connections or more, with financial obligations over $500k to the Texas Water Development Board, or with surface water rights from the Texas Commission on Environmental Quality must submit a plan. Plans must be revised every five years and include goals for reducing total, residential, and water loss gallons per capita per day. Details on leak detection programs, non-promotional water rates, conservation best practices, and annual reporting are required. Resources from the Texas Water Development Board like online reporting tools and training are available to help utilities develop effective water conservation plans.
The document discusses new and updated best practices for water conservation planning. It highlights the importance of developing five-year conservation plans and customizing practices to the specific needs and patterns of individual communities. Communities are encouraged to analyze customer water usage data to prioritize effective best management practices such as assistance programs for economically disadvantaged customers, outdoor watering schedules, enforcement of irrigation standards, and custom conservation rebates for industrial and commercial users. Developing a plan that thoroughly discusses strategy, selected practices, and evaluation can receive gold star recognition.
Presentation by Dr. Joanna Endter-Wada, professor of policy and social science at the Quinney College of Natural Resources Department of Environment & Society, at the 2019 Central Texas Water Conservation Symposium.
This document discusses water planning for Texas' future water needs. As the state's population grows and climate change brings more extreme weather, Texas faces increasing water shortages. The document evaluates different water supply strategies based on their environmental impacts, costs, and long-term viability. It recommends water conservation, integrated "One Water" planning, and nature-based solutions as the top three strategies. Water planning occurs at the state, regional, and local levels through organizations like the Texas Water Development Board and regional water planning groups. Citizens can get involved by learning about their community's water needs and proposed strategies.
The document discusses freshwater inflows and instream flows in the Colorado River basin. It provides data on the amount of freshwater that flowed into the Colorado River and Matagorda Bay in 2017, including over 2 million acre-feet into the river and around 222,000 acre-feet into the bay. It also notes that the City of Corpus Christi diverted around 1,500 acre-feet of water in 2017 and that over 180,000 acre-feet evaporated from reservoirs in the basin. The document emphasizes the importance of maintaining freshwater inflows for supplying nutrients, sediments, and balancing salinity in estuaries.
An estuary is a body of water formed where freshwater from rivers and streams flows into the ocean, mixing with seawater. Estuaries provide habitat and nutrients that support a wide variety of plant and animal life. They also play an important economic role by supporting commercial and recreational fisheries. The Matagorda Bay ecosystem leader works on projects like restoration and hatcheries to maintain the health of the bay system, which provides shelter and food for larvae, eggs, birds, and insect pollinators.
The Matagorda Bay system faces several challenges and threats, including an Alcoa Superfund site near Point Comfort that contaminated Lavaca Bay, declining water quality and flows in rivers due to development, and loss of oyster reefs. Conservation efforts aim to restore flows, improve water quality, and rebuild oyster reefs through projects like off-channel reservoirs, water monitoring programs, and oyster shell planting.
This document provides an overview of Matagorda Bay, including its history, economic contributions from agriculture and seafood industries, and impacts from development projects like dams and reservoirs. It lists ongoing planning efforts to address issues like sea level rise and habitat restoration through projects like beach protection, hydrological restoration of marshes and bays, and reef restoration.

Monitor indicators of genetic diversity from space using Earth Observation dataSpatial Genetics
Genetic diversity within and among populations is essential for species persistence. While targets and indicators for genetic diversity are captured in the Kunming-Montreal Global Biodiversity Framework, assessing genetic diversity across many species at national and regional scales remains challenging. Parties to the Convention on Biological Diversity (CBD) need accessible tools for reliable and efficient monitoring at relevant scales. Here, we describe how Earth Observation satellites (EO) make essential contributions to enable, accelerate, and improve genetic diversity monitoring and preservation. Specifically, we introduce a workflow integrating EO into existing genetic diversity monitoring strategies and present a set of examples where EO data is or can be integrated to improve assessment, monitoring, and conservation. We describe how available EO data can be integrated in innovative ways to support calculation of the genetic diversity indicators of the GBF monitoring framework and to inform management and monitoring decisions, especially in areas with limited research infrastructure or access. We also describe novel, integrative approaches to improve the indicators that can be implemented with the coming generation of EO data, and new capabilities that will provide unprecedented detail to characterize the changes to Earth’s surface and their implications for biodiversity, on a global scale.
There is a tremendous amount of news being disseminated every day online about dangerous forever chemicals called PFAS. In this interview with a global PFAS testing expert, Geraint Williams of ALS, he and York Analytical President Michael Beckerich discuss the hot-button issues for the environmental engineering and consulting industry -- the wider range of PFAS contamination sites, new PFAS that are unregulated, and the compliance challenges ahead.
Widespread PFAS contamination requires stringent sampling and laboratory analyses by certified laboratories only -- whether it is for PFAS in soil, groundwater, wastewater or drinking water.

(Q)SAR Assessment Framework: Guidance for Assessing (Q)SAR Models and Predict...hannahthabet
The webinar provided an overview of the new OECD (Q)SAR Assessment Framework for evaluating the scientific validity of (Q)SAR models, predictions, and results from multiple predictions. The QAF provides assessment elements for existing principles for evaluating models, as well as new principles for evaluating predictions and results. In addition to the principles, assessment elements, and guidance for evaluating each element, the QAF includes a checklist for reporting assessments.
This new Framework provides regulators with a consistent and transparent approach for reviewing the use of (Q)SAR predictions in a regulatory context and increases the confidence to accept alternative methods for evaluating chemical hazards. The OECD worked closely together with the Istituto Superiore di Sanità (Italy) and the European Chemicals Agency (ECHA), supported by a variety of international experts to develop a checklist of criteria and guidance for evaluating each criterion. The aim of the QAF is to help establish confidence in the use of (Q)SARs in evaluating chemical safety, and was designed to be applicable irrespective of the modelling technique used to build the model, the predicted endpoint, and the intended regulatory purpose.
The webinar provided an overview of the project and presented the main aspects of the framework for assessing models and results based on individual or multiple predictions.
The modification of an existing product or the formulation of a new product to fill a newly identified market niche or customer need are both examples of product development. This study generally developed and conducted the formulation of aramang baked products enriched with malunggay conducted by the researchers. Specifically, it answered the acceptability level in terms of taste, texture, flavor, odor, and color also the overall acceptability of enriched aramang baked products. The study used the frequency distribution for evaluators to determine the acceptability of enriched aramang baked products enriched with malunggay. As per sensory evaluation conducted by the researchers, it was proven that aramang baked products enriched with malunggay was acceptable in terms of Odor, Taste, Flavor, Color, and Texture. Based on the results of sensory evaluation of enriched aramang baked products proven that three (3) treatments were all highly acceptable in terms of variable Odor, Taste, Flavor, Color and Textures conducted by the researchers.

2. The Problem
Many cities in North America are already challenged to
meet their customer demands for water
Growing population and economic growth will place
even more pressure in arid and water-short areas
As drought and water shortages occur, residents raise
the issue about available water for new development
when they are being restricted
Some communities cannot accommodate growth with
current water supplies
3.
4.
5. The Answer: Water Offsets
Can allow growth without increasing system-wide
water consumption across a community or a
water supply service area
Can be a combination of on-site water efficiency
and off-site water efficiency
Can reduce or completely eliminate impact of
new development on water supply
Can help avoid building moratoriums in resource-
constrained communities
