NorthStar Engineering can provide solutions to your onsite wastewater needs when standard onsite systems will not meet individual sites conditions and state and local regulations, or have failed to perform. We have extensive experience with the following alternative onsite wastewater treatment systems: re-circulating sand/gravel filtration systems, sequence batch reactors (SBR), aerobic systems, and alternative disposal/reuse options including drip irrigation. Many of our designs incorporate remote management and monitoring controls, and all of our designs include operations and maintenance support. Our capabilities enable us to design onsite systems that provide secondary level treatment and when the site constraints demand, even tertiary level treatment. These systems enable development of some sites that otherwise would not sustain improvements. Our highly specialized staff has over 25 years of cumulative experience. Several of our engineers serve as trainers to other engineers and designers at the California Wastewater Training and Research Center at California State University, Chico.
