In June 2015, ISD officially opened two different Recycled Water Fill Stations—a Residential Recycled Water Fill Station and Commercial Recycled Water Fill Station. Each offers high-quality recycled water available for outdoor watering needs.
The Residential Recycled Water Fill Station located near ISD Main Office at its headquarters in Oakley allows Oakley and Bethel Island residents FREE access to available recycled water for irrigation of plants, trees, and gardens.
The Commercial Recycled Water Fill Station located near the Water Recycling Facility at Ironhouse's headquarters in Oakley offers a way to conserve potable water and can be used for construction purposes, including grading and compaction, wetting pads, dust control, landscape irrigation, and more. Please call the District for information on the Commercial Fill Station at 925-625-2279.
Residential Recycled Water Fill Station
