Lake Worth is the second oldest manmade lake in Texas. The lake is a source of drinking water for the City of Fort Worth. APAI has been working with the City for approximately 25 years to extend water and sanitary sewer services to areas adjacent to the lake. These areas depended on water wells for water supply and septic tanks for sewage disposal. The extension of city services will improve the water quality in the lake.
Casino Beach and Watercress Drive Water and Sewer Improvements, Phase 1 is the first phase of several improvements in this area and is the latest Fort Worth project APAI is designing. There are five miles of water lines, a gravity sewer, and lift station. The scope of work included evaluation of two existing lift stations for possible abandonment of one of those lift stations. The scope also included site selection for the new lift station on Casino Beach.
To correctly size the lift station, APAI calculated the peak flows from lots along the lake shore and sized the low pressure sewer and gravity main and the new Casino Beach lift station to convey these flows to the east side of the lake to an existing lift station. The calculations showed that a 0.6-MGD lift station is needed for ultimate flows.
APAI calculated water demands for the service areas and updated the City’s water model. The updated model helped to size the proposed waterline to provide fire flow and peak demand flows. The project included coordination with several departments at the City and an alignment evaluation of the waterline force main and gravity sewer. Phase I also included the design of a force main under Lake Worth to be constructed by horizontal directional drilling.
