Handling over 2.5 million gallons of water a day is tough, but this state-of-the-art facility is equipped for the task. On the surface, Ironhouse's state-of-the-art Water Recycling Facility looks like a simple collection of buildings and structures, but hidden behind these walls is a complex of piping and processes designed to turn the wastewater our communities generate into a product that is safe to return to the environment and safe to reuse for irrigation.

The Collections Department at Ironhouse Sanitary District is responsible for maintaining the sewer system and equipment that carry wastewater from homes, schools, and businesses to the Water Recycling Facility. Collections staff inspect, clean, repair, and monitor sewer lines to help prevent blockages, backups, and overflows. They also respond to emergencies 24 hours a day, 7 days a week, 365 days a year. Their work helps protect public health, prevent pollution, and keep local waterways clean for residents in Oakley and Bethel Island.

Recycled Water Fill Station

Ironhouse Sanitary District has proudly offered recycled water to the community since opening its Residential and Commercial Recycled Water Fill Station in June 2015. Ironhouse offers free recycled water to ratepayers in Oakley and Bethel Island for outdoor, non‑potable uses. Non‑ratepayers may participate by purchasing a $35 seasonal permit. This program helps keep trees, gardens, and landscapes healthy while saving drinking water and reducing water bills.

Fats, Oils, and Grease (FOG) Drop-Off

Residents can help protect the sewer system by properly disposing of fats, oils, and grease (FOG). Instead of pouring cooking grease down the drain, allow it to cool, collect it in a sealed container, and bring it to Ironhouse Sanitary District for proper disposal. When grease enters sewer pipes, it can harden and cause blockages that may lead to sewer backups and overflows. By dropping off FOG at Ironhouse, residents help keep the sewer system running smoothly, protect public health, and prevent pollution in local waterways. This simple step makes a big difference for our community and environment. Learn more about our FOG Drop-Off Facility.
