Advanced Wastewater Treatment
The Hoot System Difference
Superior On-Site Solutions is California’s authorized manufacturer and distributor of Hoot advanced aerobic treatment systems — engineered for sites where conventional septic simply won’t do.
A Better Approach to On-Site Wastewater Treatment
Not every property can support a conventional septic system. Small lots, steep terrain, poor soil conditions, high groundwater, and environmentally sensitive areas all present challenges that standard systems aren’t designed to handle. The Hoot advanced aerobic treatment system was built specifically for these situations — delivering high-quality treatment in a compact, reliable package that meets California’s strict regulatory standards.
Unlike a conventional septic tank that relies on slow, oxygen-free decomposition, the Hoot actively aerates the wastewater inside the tank. This aerobic process is far more efficient, producing cleaner effluent with significantly reduced levels of biological oxygen demand, suspended solids, and nitrogen. The result is a system that works harder, treats better, and opens up development and improvement options on properties that would otherwise have no viable path forward.
California’s authorized Hoot manufacturer and distributor: Superior On-Site Solutions manufactures Hoot tanks right here in California and distributes them statewide. We’re California’s only authorized Hoot manufacturer and distributor — your direct source for Hoot systems and the local experts who know how to specify, commission, and support them for the life of your system.
What Hoot Systems Deliver
Every Hoot system is NSF/ANSI certified and engineered to achieve measurable treatment results. Depending on the model, Hoot systems provide:
Dramatically reduces biological oxygen demand before effluent reaches the drain field.
Nearly eliminates total suspended solids, producing clear, odorless effluent.
The ANR model goes further, exceeding the EPA’s drinking water standard for nitrogen — making it the right choice for nitrogen-sensitive environments and properties with minimal separation from groundwater.
Hoot System Options
We offer the full line of Hoot systems to address a wide range of site conditions and treatment requirements. Here’s a quick overview of what’s available:
Hoot BNR System
Basic Nitrogen Reduction — the workhorse of the Hoot line. NSF/ANSI Standard 40 certified for residential sites with challenging conditions. The standard California setup pairs the Hoot tank with a pump tank, giving you the pressurized dosing most advanced dispersal methods require.

Advanced Nitrogen Reduction — the highest-performing model in the Hoot product line. Certified to exceed EPA’s 10mg/L drinking water standard for nitrogen. Required for the most sensitive sites.
Learn More →Commercial / Municipal Hoot
Engineered for schools, government facilities, commercial developments, and other high-flow applications. Scalable design with advanced monitoring and nutrient reduction capabilities.
Learn More →Traffic-Rated Hoot System
Reinforced concrete construction allows installation beneath driveways and parking areas — ideal for small lots where every square foot of usable land matters.
