Pump Stations/Facilities

Chocolate Bayou Pump Station—Gulf Coast Water Authority, Alvin, TX
GCWA Canal Division operates the existing Chocolate Bayou Pump Station, a surface water pump station which was built to supply irrigation water to agricultural customers. Demand over the years has changed from exclusively agricultural to mostly industrial and existing pumps station is unable to meet the demand. This lead GCWA to pursue construction of a new pump station for the Chocolate Bayou system. A+ Services was selected to provide technical support to prime engineer, which included the review of the pump station preliminary design. As part of the effort, ATS also provided preliminary structural design for pump station.

 

Virginia Point Metering Stations—Gulf Coast Water Authority, Texas City, TX
The GCWA supplies the City of Galveston with water through two existing waterline systems. However, concerns about the condition of the existing waterline and redundancy in its system prompted the City of Galveston to pursue construction of an additional waterline attached to existing IH-45 bridge to Galveston. The third waterline will require GCWA to increase the pressure in its existing system. A+ Services has selected to develop the design for two (2) 20” above-ground pressure reducing and metering station to control pressure and flow to the existing waterlines supplying Galveston. Both metering stations used full-port electromagnetic flow meter, electronically controlled flow control valve with pressure reducing and pressure sustaining features, and required above ground storage for SCADA controls. A+ Services’ efforts included the assessment of optimal locations for the stations, evaluation of pressure reducing valve sizing, development of piping and structural design, and construction phase services for the project.

 

30”/42” Waterline from Knight and Holmes Road to Sims Bayou Pump Station—City of Houston, Houston, TX
This project involved 39,000 LF of 42” water transmission line and incorporated pump station improvements to Sims Bayou PS (SBPS), including 30” yard piping, a new 30” metering station, four 30” tank connections at the SBPS, and improvements to the chlorinator, ammoniator, and SCADA system. In addition, the project included extensive pavement reconstruction along concrete roadways. The project was constructed with a combination of PCCP, Barwrapped, and steel waterline.
