City of League City, Texas

Decommission and Demolish Bay Ridge GST and BPS. Project will remove the booster pump station, ground storage tank, Hydro-tank, and misc. site equipment. This project will work in conjunction with Bayridge Park Phase 2 renovation (PK1902). Water Distribution System improvements over past years have eliminated efficient utilization of this site. The demolition and removal of site faculties will restore area to useful greenspace for the neighborhood.

Construction of permanent CMU chemical feed room and storage area with associated mechanical and electrical; including area lighting improvements near meter, incoming pipe, and chemical feed. Chemical feed equipment, analyzers, for Chloramine and Liquid Ammonium Sulphate (LAS), with leak detection and fire suppression. Secure storage area for aforementioned chemicals will be included in CMU building sq footage. The 2014 Improvements at SH3 BPS minimized Chemical feed addition in a cost savings effort that was based from a long standing history of above average disinfectant residuals from SEWPP transmission water line. A small scale portable chemical feed system was provided to feed chemicals to booster or sustain disinfectant residual during everyday and emergency operations. Since the 2014 start up, Water Production Operations has experienced multiple summer seasons where unusual high demands created the need to boost Chloramine residuals in the GST’s located at SH3. The existing scaled down system, lacks adequate storage and requires frequent CL2 150 lb cylinder changes during these high use events.

“The project identified in the 2018 Water Master Plan and will consist of the land purchase, engineering, and construction of a booster pump station, ground storage tank and groundwater well. The project will be located on the west side of the City, west of the future Bay Area Boulevard and North of FM517 (Westside PUD Drill Site) on a site to be determined. 2018 CRF Study reflects 100% project cost are eligible for Water CRF funding. This project is linked to the 16″” Water line to West Side GST & BPS project and must be completed at the same time. This facility is necessary in order to meet future development needs on the west side of the City and to provide a looped system to the City’s existing west side infrastructure, thereby providing back-up capacity, pressure and fire protection to the
west side of the City.”

Project identified in 2018 Water Master Plan and includes design and construction of 1,300 LF of 16-inch water line from the future 24-inch water line to the future Grand Parkway to the proposed West Side Booster Pump Station, GST, and Well. 2018 CRF Study reflects 35% project cost are eligible for Water CRF funding. This project is linked to the New West Side Booster Pump Station, GST, and Well project and must be completed at the same time. This project is identified in the 2018 water master plan and is required for connectivity to the City’s existing west distribution system to provide future service capabilities to the proposed 2 MG ground storage tank & BPS. This system feature provides ground storage and associated pressure enhancements for future development of the far west service area.

Identified in the 2018 Water Master Plan this project consists of the design and construction of a 20 MGD treatment module addition to the Southeast Water Purification Plant (SEWPP). This treatment facility is currently rated at 200 MGD and provides finished drinking water to the City of Houston and a multitude of co-participating communities South of Houston to Northern Galveston County. The expansion will include all key and peripheral components of a Conventional Surface Water Treatment Plant, including but not limited to, conveyance and process pumping, coagulation and sedimentation basins, filtration, disinfection contact basins, chemical feed, etc. Funding for the 20 MGD Expansion of SEWPP will be evaluated during FY2027 to designate a budget based on available Water CRFs. From today’s dollars an estimated budget of $9.5M is programmed for this project. This project is necessary to provide the additional drinking water capacity required to meet and sustain the capacity demands for future growth up to ultimate build out. The completion of this capacity expansion will be the final step in a long standing effort to secure and deliver a long term reliable water source for League City’s future. The pace of Development over the next five to ten years will drive the initiation process to begin the expansion. Design and construction is estimated at 36 months.
