Miraloma Recharge Basin

When the Orange County Water District (OCWD) identified the need for a new percolation basin, they enlisted our Â鶹´«Ã½. Built on a 13-acre site in Anaheim, the Miraloma Basin is a vital addition to OCWD¡¯s groundwater management system that allows the percolation of up to an additional 6,000 acre-feet of water ¡ª enough for 50,000 people. Prior to construction, thousands of acre©\feet of water were lost every year due to insufficient recharge capacity in the region.

Our engineering and construction support services included preparing a preliminary design report and plans, specifications, and estimates. The selected alternative provides a balance of cost savings and functionality through reduced pipeline lengths and a basin configuration that allows for a future lowering of the basin floor.

This facility is devoted to water from the groundwater replenishment system, the world¡¯s largest advanced wastewater purification system for indirect potable reuse. Although only recently put into service, the basin yields the highest measured percolation rates among OCWD¡¯s 21 basins due to favorable geology and ultra-pure GWRS water.
