Well 20A Construction

The City of Atwater is undertaking the Well 20A Construction project to replace the failed potable Well 20. The scope of work involves drilling a new well, designated as Well 20A, at the same site as the original well and subsequently destroying Well 20. Well 20A is designed to maintain a capacity similar to the original well, ensuring there is negligible or no expansion of capacity. The new well will be integrated into the City of Atwater's distribution system for potable water use and will feature a treatment system utilizing granular activated carbon to remove 1,2,3-trichloropropane. The project is located at 709 Rancho Vista Dr., Atwater, California 95301, and falls under NAICS code 237110. On September 2, 2025, the State Water Resources Control Board issued a domestic water supply permit amendment and plan approval for the project. Additionally, a Notice of Exemption was issued based on California Code of Regulations section 15302, classifying the project as a replacement or reconstruction. Primary points of contact for the project include District Engineer Orlando Gonzalez and Public Works Director Justin Vinson.
