Document Description
In order to fully utilize Irvine Ranch Water District's (IRWD) Michelson Water Reclamation Plant (MWRP) treatment capacity to provide additional recycled water, IRWD is proposing the Harvard Avenue Trunk Sewer (HATS) Diversion project. The HATS Diversion project would allow existing wastewater that currently flows to the Orange County Sanitation District (OCSD) system to be re-directed to the interceptor sewer's tributary to the MWRP. In March 2006, Earth Tech completed a preliminary planning report which identifies the proposed HATS Diversion project from several scenarios for diverting raw sewage from the HATS area to MWRP. No additional capacity to treat wastewater or to produce recycled water is proposed as part of the project.
