Brelje & Race offers the resources and depth of experience to transform any wastewater into clean water suitable for a wide variation of reuse opportunities. Our goal is to provide our clients with innovative systems and processes that deliver operational ease, flexibility, and resiliency.

We have planned, permitted and engineered complete municipal wastewater plants with flow rates ranging from 0.6 to 2.3 million gallons per day (mgd), average dry weather flow (ADWF) and have improved discrete process elements of plants rated for up to 18.0 mgd ADWF. We also specialize in on-site treatment and reuse systems for a variety of private domestic industrial waste streams.

Our knowledge of regulations, policies, and procedures, especially in the sensitive environment of Northern California, provides you with a partner for success in any situation.
