Cisterns. As part of a xxxxxxxx-wide effort to reduce potable water usage, 5 large underground cisterns have been installed. The 35,000 gallon cistern south of Building 613 stores water for toilet flushing at buildings 607 and 613. Two 20,000 gallon cisterns east of building 613 and two 20,000 gallon cisterns in the parking lot just west of building 566 store water for irrigation. The PMSA shall inspect, maintain, and repair these cisterns; and shall maintain a log to show when inspections were performed. Inspections shall be performed semi-annually, or as required by health code. Draining or emptying of any cistern requires coordination with DPWE. Maintain Cisterns to optimize water savings. The PMSA shall provide maintenance to cisterns and associated equipment including pumps, filters, back-flow devices, controls, etc. Water quality shall be checked and tracked, and preventative maintenance such as filter replacement shall be done.
