Houston, SJRA's GRP Program
This document summarizes SJRA's Groundwater Reduction Plan program in Montgomery County. It discusses that Montgomery County faced a water supply problem due to groundwater regulations. SJRA proposed a conjunctive use solution pumping surface water from Lake Conroe, which 85 local entities agreed to. Phase 1 of the program included a 30 mgd water treatment plant, 52 mile transmission system, and modifications to deliver surface water to six participants and reduce groundwater use. The $490 million project is the largest civil works project in the county. It highlights construction communication strategies, customer review committees, transparency reporting, and using competitive proposals to engage local vendors for the project.

San Jacinto RiverAuthority • Created in 1937; seven member board appointed by the Governor • Primary purpose – Long-term, regional water resource planning and development • Secondary benefit – Partnering with local entities on water-related projects or services (such as regional water and wastewater systems, dam and drainage system maintenance, and development of new drinking water supplies)

- 4. Why the GRPprogram? • Montgomery County has a water supply problem. • Regulations were adopted to force utilities to find a solution. • SJRA offered a “regional” solution that proposed conjunctive use of surface water from Lake Conroe. • SJRA’s proposal was made available to all regulated utilities in the county on a cost-equal basis regardless of their location. • 85 entities chose to join representing 80% of county demand. 2015 204520352025 20602055 Regulated Groundwater Available

Editor's Notes
- #5 The goal of the SJRA’s proposed GRP is to create a countywide solution that is available for ALL LVGUs in the county. In other words, a plan that allows us ALL to achieve compliance with the LSGCD’s rules. The Lone Star’s rules specifically allow LVGUs to join together to form a regional solution. Any LVGU that chooses to join the SJRA’s plan would be considered in compliance with the LSGCD’s groundwater reduction requirements. This group approach to compliance is the key to creating the LOWEST POSSIBLE COST for all water users in the county.
- #7 This chart illustrates our strategy for meeting the regulatory requirements by expanding surface water capacity and reducing groundwater use at ten year intervals. New growth will be allowed to use groundwater as long as the average over the milestone years is <37.5 mgd. Future expansions will be built to supply more surface water as the water demand grows.

- #18 The LVGUs have a panel of representatives that watch over the SJRA’s implementation and management of the GRP. This group is called the GRP Review Committee. There is a representative appointed by the City of Conroe, The Woodlands Joint Powers Agency, and one appointed by the LSGCD to represent investor owned utilities. In addition, there are three members elected by the LVGUs to represent other cities, MUDs east of I-45 and MUDs west of I-45. The Review Committee meets monthly and votes to recommend approval of budgets, contracts, rates, policies and the admission of new members to the GRP. Mike Mooney – JPA representing The Woodlands Joint Powers Agency Scott Taylor – Conroe representing the City of Conroe Joe Sherwin – City of Oak Ridge North representing small cities Kerry Masson – Southern Montgomery County MUD representing MUDs east of I45 Jackie Chance – WCID -1 representing MUDs west of I45 Richard Wagner – Appointed by LSGCD representing investor owned utilities
