Alternative Treatment Systems
Alternative treatment systems can be used to address specific soil conditions that prevent conventional septic systems from being installed. However, they can be more expensive to construct and maintain. A registered PR will know when an ATU is appropriate for your project. ATUs installed in Riverside County require an annual operating permit through this department.
