Joshua Basin Water District Recharge Basin and Pipeline Project

Joshua Basin Water District Recharge Basin and Pipeline Project

JBWD proposes to construct one recharge basin facility that would be ~20 to 25 acres in size, and an extension of the Morongo Basin Pipeline from its existing terminus on Yucca Mesa Road to the new basin. Three alternative locations for the rechange basin are considered in the DEIR at an equal level of detail. The project would require a total of 29 acres for basin construction, which would include 22 wet acres; and would also involve construction of multiple (up to 6) 6 to 7 ft deep subbasins within the recharge basin. Subbasins would be seperated by overflow earthen weirs, allowing water to flow from subbasin to subbasin as needed. Control valves (housed within a small building on the site) would be used to add water to the subbasin, as necessary. Water levels within the basins would not exceed original grade elevation and would be maintained at depths of three to five ft. Annual average recharge is anticipated to be ~2000 acre ft per year. However, with the availability of water being less than a full year, each site would be designed to allow the 2,000 acre ft per year recharge with a 50% water delivery scheduled. Therefore the recharge basins would be designed to accommodate a total capacity of up to ~4,000 acre ft fo half of the year to meet the goal of 2,000 acre ft per year of recharge. The earthen berms would visually screen the basin; an 8 ft chain-link fence would surround the site. The proposed pipeline would include up to 24,000 linear ft of 16-24 inch diameter pipe connecting to the existing Morongo Pipeline at Yucca Mesa Road. The pipeline would be constructed within existing roadway rights-of-way.
