Hoot Advanced Septic Systems in Napa County
For Homes, Wineries & Hospitality
We supply, start up and service Hoot advanced treatment systems for Napa County homes, wineries and commercial properties, from the valley floor to Angwin, Pope Valley and the eastern hills.
Protecting Napa’s Soils and Waterways
Napa County properties range from hillside estates with thin soils to valley parcels near creeks and the Napa River. Many sites need a higher level of treatment, or a smaller footprint, than a conventional system can deliver.
Wineries and hospitality properties add another layer: larger and more variable daily flows. Commercial Hoot systems scale up to handle that, with the same in-tank aerobic treatment as our residential systems.
Already have an alternative system? Napa County requires alternative sewage treatment systems to operate under an Operational Permit, with a service provider monitoring the system. We provide O&M service for Hoot systems.
How Napa County Regulates Advanced Septic Systems
In Napa County, onsite wastewater systems are permitted by the Environmental Health Division of Planning, Building & Environmental Services (PBES), which also permits and inspects alternative sewage treatment systems.
- Alternative sewage treatment systems in Napa County must be operated under an Operational Permit, renewed for as long as the owner keeps the property.
- Owners agree to hire a service provider to monitor the system at the frequency the county requires.
- Owners also grant county and Regional Water Board staff access to observe, test and sample the system.
- Every Hoot in California requires a lifetime Operation & Maintenance (O&M) agreement, which we provide.
Rules change and every parcel is different. Confirm current requirements with the county (Napa County Well & Onsite Wastewater Treatment), and call us with questions. We’ve worked with California county environmental health departments since 2006.

Artesa Vineyards & Winery, Napa
For the final piece of its sustainability program, Artesa needed 2,400 gallons per day of commercial-strength treatment. RSA Civil Engineers specified two Hoot H-1000 BNR tanks with an ACT-2000 self-cleaning filter, achieving a 99% reduction in CBOD and TSS.
