La Mesa Cliffs, a new 50 unit single-family and duplex housing complex on a Navy-owned site at the Naval Postgraduate School in Monterey, California. Due to extreme water cost and supply issues in the Monterey area, the developer voluntarily chose to develop La Mesa Cliffs with a graywater recovery system to reduce the need for potable irrigation water.
It is one of the largest graywater landscape uses in the nation and serves as a case study to assist municipalities who are currently considering integrating this alternative source of water into their areas of jurisdiction. This was the first system commissioned in the region and included involvement by many stakeholders to ensure all parties were comfortable with the process to recycled residential graywater and apply it to public areas.
All residential landscape and community park areas of this innovative 11 acre military family housing community are supplied by the graywater collection from the 50 single family housing units. The graywater system has eliminated the need for potable water on most days.
Work continues with the construction team and local water suppliers to monitor the system.
