RECENT CLIENTS

Purple (Panatone 249 C) is the standard color for pipes and fittings conveying recycled water.  This particular color was innovated at Irvine Ranch Water District in the 1970s  to distinguish recycled water lines from potable water lines.  This color standard is now adopted nearly universally wherever recycled water is used.

The Japanese Garden at the Tillman Water Reclamation Plant in the City of Los Angeles, uses recycled water for irrigation and supply to the  Lake, which supports a variety of fish.  The Japanese Garden boasts some of the most exotic, sensitive, and highly valued plant materials.  Initial skepticism about the potential effects of switching to recycled water was allayed with a pilot project  whereby half of the garden was irrigated with potable water and the other half with recycled water.  After a few years with no differences seen in the two halves, the entire garden was then irrigated with recycled water and that success has continued without interruption since the early 1990s.  The Japanese Garden is a community resource and is venue for many a wedding and celebration.
