The AIPS is located within the Plant and transports wastewater from the Alvarado drainage basin to the Headworks through a force main that is separate from the other two pump stations. This project includes improvements to the AIPS and Headworks facility. The AIPS component consists of the replacement of five wastewater pumps and VFDs, valves, piping and actuators, main switchgear, and building roof membrane.
