One of our Associate Engineers completed design and construction oversight for the City of Bellingham 54-inch pipe outfall from the local treatment plant.

Our firm has gained very specific experience with projects that must convey small and large volumes of storm water (and/or waste water) down steep slopes into ponds, streams and marine environments.  The pipeline shown above required the extension of a 54-inch outfall pipeline about 500 feet into Bellingham Bay, Washington.  We also design flow control structures, conveyance systems, drop structures for steep slopes and energy dissipaters.

We design storm water collection systems for;

  • Small and Large Urban Developments
  • Single Residential Propertes
  • Municipal Storm Water Treatment and Detention Ponds
  • Drainage Systems for Mining Properties
