Wastewater

> Projects > Water Management > Wastewater

Collection and movement of waste flows from residential, commercial, and industrial areas pose problems of a different nature from those of water supply. Waste flows are highly variable and contain coarse solids that may be floating or suspended. The design of sanitary sewers involves the determination of the design flow and the application of hydraulic engineering principles to devise adequate conveyances for transporting these flows.

Our engineers at Cochran have extensive knowledge and experience regarding environmental regulations. Our staff has become very proficient in obtaining local and state permits and approvals. We have very experienced professionals who specialize in all facets of wastewater collection and treatment.

Our wastewater treatment projects range from preliminary processes (pumping, screening, and grit removal), primary settling to remove heavy solids and floatable materials, and secondary biological aeration to metabolize and flocculate colloidal and dissolved organics. Including thickened sludge, which is processed for disposal.

Cochran is committed to serving its clients, preserving our environment and meeting regulatory standards by designing state-of-the-art, easy-to-operate and cost-effective wastewater collection systems and treatment facilities. Our focus on both current needs and anticipated regulatory standards – and our attention to detail – brings your project from conceptual planning through design, financing, construction and successful operation. Cochran engineer’s work closely with government agencies, and with thorough knowledge of environmental regulations, can assist in obtaining federal, state and local permits and authorizations.
