Kansas City's Overflow Control Program, 2012, u.s. water alliance,urban water...U.S. Water Alliance
Kansas City has made a commitment to use green infrastructure as a way to address its combined sewer overflows and to become one of the most sustainable cities in the country. This presentation will provide an overview of the Kansas City's Green and Water Works programs. As part of Kansas City’s federally-mandated Overflow Control Program, a 744-acre green infrastructure project is underway in one watershed to reduce combined sewer overflows. Green infrastructure is used to intercept stormwater, keeping it out of the combined sewer system, reducing the overflow and the amount of excess water that gets pumped and treated. To further enhance the green infrastructure efforts, the City is working with residents and neighbors to make improvements on their own properties by reducing water consumption and reducing the amount of stormwater that leaves a property through runoff or direct connections to the sewer system. Kansas City's project is one of the largest green infrastructure projects in the United States to reduce combined sewer overflows.

The project involves constructing a new 500 million gallon per day pump station, 3.6 miles of pipeline, and 23 miles of canal. The project will provide additional surface water supplies needed to meet regulatory requirements for Houston and other areas to convert water usage from groundwater to surface water. Corridor 3 was selected as the preferred route for the project.
The document summarizes a presentation given on current challenges in the potable water industry in Southeast Texas, focusing on Montgomery County. It discusses the county's rapid population growth and reliance on groundwater from the Gulf Coast Aquifer, which is being overpumped. The Lone Star Groundwater Conservation District is tasked with conserving groundwater resources and has implemented regulatory phases requiring a transition to alternate water sources like surface water to reduce groundwater use. Major challenges include developing infrastructure to access surface water, negotiating contracts, and achieving equitable solutions for all users in the county.
The Groundwater Rule requires additional protection of groundwater sources from contamination by viruses and bacteria. It has four major components: 1) periodic sanitary surveys to identify deficiencies, 2) source water monitoring for E. coli or other indicators, 3) corrective actions for contaminated sources or deficiencies, and 4) compliance monitoring for systems using treatment. The rule establishes monitoring, public notification, and corrective action requirements triggered by contamination detection to help ensure groundwater is disinfected. States have flexibility in implementing specific monitoring requirements and determining compliance options available to public water systems.
The document provides an overview of water rights in the Lower Trinity and San Jacinto Basins in Texas. Surface water in Texas is owned by the state and available for use under statutory appropriation. There are different types of water rights like perpetual rights from certificates of adjudication and permits, as well as limited term rights from term and temporary permits. The document outlines the water rights and supplies of cities like Houston from various sources such as Lake Conroe, Lake Houston, Lake Livingston, and the San Jacinto River.
Karl Pepple, Director of Environmental Programming with the City of Houston. He reviewed the City of Houston's wastewater treatment energy expenditures and emissions associated with that energy use.
This document discusses the key considerations for a utility converting from groundwater to surface water sources. It outlines the public perception challenges, increased costs associated with capital investments, operation and monitoring, and the need for greater treatment and system operation expertise. Specifically, surface water requires more sophisticated treatment like chloramination, extensive water quality monitoring, and management of water age and storage to properly maintain water quality standards.
David Scholler, PE, Senior Project Manager at Brown & Gay Engineers, Inc. discusses the planning that North Fort Bend Water Authority has and will complete in order to meet Fort Bend Subsidene District's mandated reduction of groundwater use.
The document discusses the impacts of Hurricane Ike on Galveston Island in 2008. Some key points:
- Storm surge was 12-13 feet behind the seawall and 10-12 feet on the west end of the island. 90% of the entire island was heavily damaged.
- Infrastructure suffered 100% system failure. Estimated damage costs were $970 million. 75% of homes were heavily flooded and businesses saw major inventory losses.
- Debris removal totaled over 1.2 million cubic yards by February 2009 and cost $43 million. Integrated utility systems like water and sewer were completely inoperable during the storm.
- Safety of personnel and citizens should be the
Rafael Ortega, PE at LAN, discusses design issues, ROW concerns, technical specifications, and critical installation and constructability of large diameter water transmission lines.
This document summarizes Texas regulations regarding membrane filtration facilities for drinking water treatment. It outlines piloting requirements, current pathogen removal credits for different membrane types and pretreatment, Long Term 2 Enhanced Surface Water Treatment Rule bin classifications and additional Cryptosporidium treatment requirements. It also discusses membrane removal credit and challenge testing requirements, direct integrity testing, and indirect integrity monitoring. The conclusions state that membrane filtration is an approved innovative treatment process in Texas, with piloting and monitoring requirements changing to comply with LT2ESWTR regulations.
The North Harris County Regional Water Authority was created by the state legislature to provide a long-term water supply for North Harris County. It presented an overview of its creation, regulatory requirements to reduce groundwater usage, plans to obtain surface water from Houston via contracts, and its Groundwater Transfer Program to address short-term water needs while developing the regional water system. The Authority also discussed funding its initial projects through bond sales and water fees.
This document summarizes the key points from a presentation given by Buck Henderson on the 2002 Bioterrorism Act and requirements for water systems in Texas. The act requires all community water systems serving over 3,300 people to complete a Vulnerability Assessment and those between 50,000-100,000 people to submit theirs by December 2003. It also discusses the development of a Critical Infrastructure Protection Council in Texas to advise the governor on security issues. The presentation covers what should be included in a Vulnerability Assessment and an Emergency Response Plan, such as identifying critical system components, potential threats, and response procedures. It provides guidance on responding to security incidents through site investigation, sampling, and public health measures like boil water advisories
1. North Fort Bend Water Authority
Direct Reuse and Conservation Considerations
February 2011
2. Multi-Pronged Approach
• GRP is based on surface water conversion only
• Board is developing incentives and other programs to encourage
Water Conservation
Water Wise Program-NFBWA directly sponsors students annually and purchases from
their MUDS credits for their support of the program.
Early delivery of surface water -At Developer or MUD request, Authority pays 100% of
engineering costs, Developer pays 50% of construction cost of his share of capacity in
pipe. All easements required by Authority will be donated by Developer. Timing and
location are key.
Water Reuse for irrigation
NFBWA provides a $0.39 per 1000 gallon credit for metered reuse. The board is
considering raising that credit to $0.75 per gallon.

3. Current conservation efforts:
Classroom materials
(TEXAS WATER; WATER IS LIFE)
•Sponsor Water Wise program
•New mobile teaching lab
•Water bill inserts
•Newsletters
Brown & Gay Engineers, Inc.
4. Credits toward Conversion
• To date the Authority has acquired 754,824,000 gals of credit
(about 70 days)
• MUDs served for 2011 and 2010 will generate 7 billion additional
early conversion credits (about 730 days)
• Equivalent to about 800 total days or little over 2 years
Brown & Gay Engineers, Inc. 4
5. Other Conservation Efforts
• Sponsoring Texas A&M Turf Irrigation Study to determine how
much water is really needed to keep grass healthy
• Implementing a Comparative Study in a new residential
development to measure the effects of separate irrigation meters
and water efficient upgrades to irrigation systems
• Evaluating subsidizing residential irrigation evaluations to educate
homeowners about water conservation while irrigating
• Purchasing low-flow spray nozzles for school cafeterias
Brown & Gay Engineers, Inc.
6. FBSD Policy Proposal
• NFBWA Water Use Reduction Credit Policy Proposal
– Earn credits for actual reduction in use on a per capita basis over the initial
30% conversion requirement
– Any credits earned by NFBWA would be used to incentivize MUDs to
implement meaningful conservation
– Under consideration now, NFBWA is hopeful decision will be made soon
– Any incentive to conserve water diminishes with each bond sale that fixes
long term debt service. During the life of the bonds, conservation will only
increase the cost of water to current rate payers.
Brown & Gay Engineers, Inc.
7. Wastewater Reuse
• The Authority encourages wastewater reuse and recognizes its
potential benefits
• Wastewater reuse can be used instead of potable water to
conserve valuable groundwater resources
• As a focal point of the efforts by the Authority to engage itself in
wastewater reuse, several goals have been identified
Brown & Gay Engineers, Inc.
8. Authority Goals for Wastewater Reuse
• Encourage Direct Reuse by GRP participants
– Encourage changes for future development
– Increase the use of incentives
• Determine feasibility of reuse projects
– Utilize a cost template to evaluate projects on a case by case basis
– Understand the long term implications for the Authority
Brown & Gay Engineers, Inc.
9. Reuse Strategy (Policy)
• The Authority has the ability to create policy to increase WW
reuse
• Acting now maximizes the potential to increase reuse in
Authority
• Various stages of development within the Authority
– Existing Development – Much of the northeastern part of the Authority (Cinco Ranch)
has been almost fully developed. It will be more difficult to instill reuse efforts within
these areas. (approximately 27%)
– New Development –Many of these developments are including reuse piping systems
within the development. (approximately 23%)
– Future (Unplanned) – Rules and regulations that are put in place by the Authority will
ensure that wastewater reuse will be part of the future developments. (approx. 50%)
– The Authority can impact 73% of development by acting now
Brown & Gay Engineers, Inc.
10. Reuse for Existing vs. Future Development
• Reuse for Existing Development
– Higher installation costs
– Minimal access, lack of planned routes
– Retrofitting existing WWTP facilities can be difficult
• Reuse for Future Development
– Lower installation costs
– Installation part of planned development
– Plan WWTP facilities for future reuse
• Reuse policy should focus on future development
Brown & Gay Engineers, Inc.
11. Water Reuse Opportunities
• Irrigation
– Golf Course Irrigation – Currently, there are 4 golf courses within the Authority.
– Green Space Irrigation (Esplanades, Green Belts, and Parks)
– Irrigation of School District Facilities
• Amenity Lakes
– Many developments have amenity lakes that are fed by separate wells
– Providing reuse water to these lakes will reduce/minimize GW pumpage

14. Amenity Lakes in Future Development
• Install purple pipe from the WWTP to the lakes for future use
• Design amenity lakes to maximize collection of storm water
• Amenity lakes shall be recharged by reuse water at a future point
in time
• Encourage irrigation out of amenity lakes (if recharged by reuse
and groundwater)

– Grand Lakes MUDs
Brown & Gay Engineers, Inc.
20. Current Reuse Efforts (cont.)
• FBCMUD 34
– Reuse water for the Meadowbrook Farms Golf Course, potentially others
– Initial Reuse = 350,000 gpd (golf course), potential = 1 mgd
• Cinco MUD 1 Reuse District
– Design will be completed mid-2011, construction to follow
– Potential Reuse = 1.64 mgd ( $8.6M)
• Grand Lakes MUD 4
– For Grand Lakes Districts (MUD 1-4)
– Reuse water for the amenity lake system for replenishment and public area
irrigation
– Potential Reuse = 0.6 mgd

26. How this might work….
• Authority funds reuse project
• Participants enter multi-party agreement
– MUD or producer of effluent
– The Authority
– The User of Effluent
• MUD operates and maintains the plant
• User pays at rate to cover Debt and O&M
Brown & Gay Engineers, Inc.
27. Traditional vs. Alternative Approach
• Traditional Approach– Purchase Surface Water from City of
Houston
– 7.5 mgd to be reserved in 2015
• Alternative Approach– Develop Reuse Sources
– 1.5 gallon credit = 5.25 mgd
Brown & Gay Engineers, Inc.
28. Where should the Authority spend its money?
• 7.5 MGD required to meet conversion requirements from 2020
through 2024
– Luce Bayou Project @$0.75/gal
– NEWPP Expansion @$1.56/gal
– 2nd Source Line @ $3.08/gal
– Internal Lines @ $2.29/gal
• Authority will pay in capital costs $7.68/gal for 7.5 MGD of COH
treated surface water
• If reuse project is less, including lost revenue, it should move
forward
Brown & Gay Engineers, Inc.
29. Cost Implications of Reuse
• Authority sees a loss in revenue (groundwater pumpage fees)
• Authority pays reuse incentives (5 years)
Brown & Gay Engineers, Inc.
30. Cost Implications of Reuse (cont.)
• MUD charges less than GW Pumpage Fee for producing reuse
water
• GW Pumpage Fee increases over time
• Therefore the reuse fee will likely increase over time (but is always
less than GW pumpage fee)
• Reuse fee should cover debt service and O&M cost for producing
reuse water
Brown & Gay Engineers, Inc.
31. Cost Implications of Reuse (cont.)
• At future point, debt service is paid and MUD makes profit on
providing reuse water
• Potentially the Authority should receive a portion of the profit made
by the MUD, to offset lost revenue
Brown & Gay Engineers, Inc.
32. Timing Considerations
• Capacity decisions will have to be made for the 2nd Source Line by
2012, shortly thereafter for the NEWPP expansion
• Debt will be issued and debt service payments will be determined
• Any capacity reduction after the debt is issued will increase the
rate for those who continue to use water
Brown & Gay Engineers, Inc.
33. Action Now affects…
• $200M Debt has been issued for 2013 system, another $50M
coming
• Any conservation/reuse we implement today will at best affect the
2015 and 2020 reservations for the 2025 system
Brown & Gay Engineers, Inc.
34. Risk Considerations
• Option 1-Assume no conservation/reuse and maintain estimated
capacity needs
– Most conservative & costly
– Most flexible for unknowns
• Option 2-Assume some level of conservation/reuse and reduce
capacity
– More risk with some cost savings
– Requires commitment to achieve reductions
