San Juan Capistrano Eastern Wells and Pipeline Project

San Juan Capistrano Eastern Wells and Pipeline Project

The proposed project would consist of the construction of two replacement groundwater production wells, along with a collection pipeline. The proposed South Cook Park Well and Well 5A are two of the seventeen wells identified in the diversion permit. The proposed collection pipeline would connect the two replacement wells, South Cook Park Well and Well 5A, plus a third existing well, Tirador Well, to form a groundwater collection system in the vicinity of San Juan Creek and south of Calle Arroyo. The collection system would supply water from the San Juan Groundwater Basin (basin) to the City of San Juan Capistrano's Groundwater Recovery Plant (GWRP, located at 32470 Paseo Adelanto) for treatment before being introduced into the public water supply system. The treatment consists of removing iron, manganese and total dissolved solids (TDS) from the groundwater. The current capacity of the GWRP is 5.1 mgd (5,712 afy) which is within the limits allocated by the diversion permit of 8,026 afy. The addition of the proposed South Cook Park Well and Well 5A along with the current operating wells will not exceed the allotted amount of water to be extracted under the diversion permit. The GWRP is currently fed by six (6) wells in the basin: Dance Hall, Tirador, CVWD No. 1, CVWD No. 2, SJBA No. 2, and SJBA No. 4. Phase 1 of the GWRP required 8 wells to feed the GWRP. The South Cool Park Well and Well 5A will complete the well requirements under Phase 1 for the GWRP, and will allow for effective management of the basin water. The purpose of the two replacement Eastern Wells (South Cook Park Well and Well 5A) is to provide system reliability and ultimately improve the flexibility of portable water production from these existing group of wells.
