Ironhouse Sanitary District has proudly offered recycled water to the community since opening its Residential and Commercial Recycled Water Fill Stations in June 2015.
Why Recycled Water Matters
Water is one of California’s most precious natural resources. By using recycled water for non‑drinking purposes such as landscape irrigation, we help conserve our limited drinking water supply. Ironhouse Sanitary District (ISD) produces high‑quality recycled water that supports our community, reduces demand on potable water, and provides a drought‑resistant water source for ISD ratepayers.
Residential Recycled Water Fill Station
ISD offers free recycled water to ISD ratepayers in Oakley and Bethel Island for outdoor, non‑potable uses. This program helps keep trees, gardens, and landscapes healthy while saving drinking water and reducing water bills.
Approved Uses for Recycled Water
Recycled water may be safely used for:
- Watering trees
- Gardens and vegetables
- Lawn irrigation
- Washing cars
- Cleaning outdoor furniture
- Washing hard surfaces such as paths, walls, and windows
Important Safety Note:
Use drinking water to wash all fruits, vegetables, or other edible plants that have been watered with recycled water.
Recycled Water Is Not Suitable For
- Drinking
- Cooking or kitchen use
- Bathing or showering
- Filling swimming pools or spas
- Children’s water toys
- Connecting to household plumbing systems

Health and Safety Rule
Tanks, pumps, hoses, or equipment containing recycled water must not be connected to any buried irrigation system, even if disconnected from your drinking water system. This prevents accidental cross‑connection with potable water.
How We Recycle Water
Ironhouse Sanitary District produces recycled water through a straightforward, multi‑step treatment process. Wastewater from homes and businesses flows to our Water Recycling Facility, where debris is removed and the water is cleaned by beneficial bacteria. It then passes through our advanced Membrane Bioreactor (MBR) system, which filters out very small particles and bacteria. Finally, the water is disinfected to remove any remaining germs. This process creates clean, high‑quality recycled water that is safely reused at the plant and provided to ISD ratepayers through the Residential Recycled Water Fill Station.
Ensuring Water Quality
ISD’s recycled water meets all state and regional water quality standards. Our treatment process includes advanced membrane filtration, disinfection, continuous monitoring, and regular laboratory testing to ensure the recycled water remains safe for all approved non‑potable uses.
Sign‑In Process
· Please sign in before filling your containers.
· Sign‑in sheets are located on the clipboard next to the Fill Station door.
· The area is monitored by cameras.
