Mesa Water District Conducting Water Flushing of Main Water Pipeline to Ensure High-Quality Water

The OC-44 Imported Water Pipeline Serves Cities of Costa Mesa and Huntington Beach; Flushing is Part of Mesa Water’s Water Quality Testing and System Maintenance Programs

Costa Mesa, Calif.; April 28, 2016 – To ensure high water quality, the Mesa Water District (Mesa Water) crews are flushing water from one of its main pipelines, called the OC-44, in two locations: Canary and Cardinal Drives in Costa Mesa, and Adams Avenue and Ranger Lane in Huntington Beach. The water flushing began yesterday and will conclude later today.

“Flushing a pipeline during a drought is unfortunate timing, nonetheless it is needed to keep water quality high,” said Paul E. Shoenberger, P.E., Mesa Water General Manager. “Mesa Water would prefer to re-use the water in some way but State regulations do not allow us to serve this water.”

This is the first time in approximately 30 years that the OC-44 has been flushed. Prior to flushing, Mesa Water explored options to possibly re-use the flushed water. However, per Division of Drinking Water regulations, re-using this water is not permitted for any purposes, including landscapes.  That said, if customers have captured this water and used it outdoors, there will be no negative impact.

“We thank our customers for their extraordinary conservation efforts during the drought; Mesa Water was hoping to re-use this water in some way but, regrettably, that is not allowed,” said General Manager Shoenberger.

The OC-44 is a main pipeline that transmits imported water to serve the cities of Costa Mesa and Huntington Beach. The OC-44 was closed for several weeks for repairs, which are complete. The water in that pipeline must now be flushed and cleaned to make it safe for service. 

General Manager Shoenberger continued, "Periodic water flushing is an important part of Mesa Water’s ongoing program to sustain its well-maintained water system. The flushing process is important for Mesa Water to continue delivering high-quality and safe water to its customers.”

During the flushing, all Mesa Water customers will continue to receive safe and reliable water service, with no impact to water pressure. Also, streets around the flushing locations are open to vehicular traffic, with Mesa Water staff directing traffic to protect the safety of drivers and pedestrians.

Mesa Water customers enjoy high-quality water that meets or surpasses all state and federal drinking water standards. Since its formation in 1960, the District has been committed to producing safe, reliable drinking water for its customers. More information about Mesa Water’s high-quality water is contained in its 2015 Water Quality Report which provides water quality and supply information about the drinking water served by the District.
