Los Osos Wastewater Facilities
RRM Design Group is responsible for the design of 11.4 miles of new sanitary sewer mains and laterals within the community of Los Osos. The projected construction cost is $5.8 million. We are also preparing calculations for sizing of the sewer mains. Since Los Osos is a developed community with an entire infrastructure, except for sanitary sewer, it will be necessary to design a gravity sewer system and address all of the utilities crossing and individual septic system tie-in points and topography. RRM Design Group will provide plan and profile sheets, laying out the horizontal and vertical location of the sewer mains and laterals to minimize the disruption and disturbance of the existing water and gas systems.
