• • • ~ task also includes evaluation of alternate supply sources and loca- tion of major treatment facilities, if required. Task 3.1 - Existing Water System Engineers will analyze existing water system to determine its ability to meet the existing system requirements and immediate growth (pre-1988). The existing system will be calibrated using pumping and .pressure records provided by the Authority from the City of La Porte's pumping stations and pressure measurements taken by the Engineer at key locations within the distribution system. Engineer anticipates approximately 12-15 points for pressure measurements and expects these to be made at a fire hydrant. If a fire hydrant is unavailable at the required location, the Authority will provide suitable taps at no expense • o the En ineer. Existin deficient areas will be noted and t g 9 Y presented in the report as requiring immediate attention. Task 3.2 - Future Water System The future water system facilities will be based on the water demand requirements determined in Task 2.0. The determination of the raw water source will dictate the direction of construc- tion of the remainder of the system. Engineer will prepare an evaluation of the viability and economic impacts of the primary alternatives of water supply. The evaluation will include the following alternatives. 1. Construction of a surface water treatment facility for alternative raw water sources. All raw water sources . within the area will initially be considered. 2. Future areawide groundwater availability. 3. Purchase of treated water from the City of Houston. 4. A combination of the above sources. The evaluation will include consideration of amortized capital costs, surface and groundwater treatment plant opera- tion costs, pumping and transmission main costs, future land requirements and costs, and engineering costs.
