The City of Healdsburg completed a major upgrade of its wastewater treatment plant which began operation in April of 2008. The $32 million upgraded treatment plant produces highly treated wastewater using a state-of-the-art membrane bioreactor (MBR) treatment process. The effluent meets “unrestricted disinfected tertiary effluent” requirements, as defined by Title 22 of the California Code of Regulations.
The treatment plant was the first phase of the city’s wastewater treatment plant upgrade project. The second component has been a recycled water delivery system, which is necessary to meet seasonal discharge restrictions contained in the city’s National Pollutant Discharge Elimination System (NPDES) permit. This comprehensive approach allows the city to not only comply with its legal requirements to eliminate discharges during the summer months, but also to beneficially reuse highly treated wastewater on public parks, community schools and other community facilities. The recycled water is now being delivered to the agricultural community outside of the City of Healdsburg as well.
