Sewer System Rehabilitation


Wastewater lift stations move wastewater from a lower to higher elevation. A lift station is a necessary element in the process of moving sewage through the system. This component of the process alleviates the need for deeper excavation, which reduces excessive costs of sewer line installation.


A collection system consists of underground pipes and maintenance structures which guide wastewater to sewer treatment systems. Since gravity alone is not enough to move the waste, a lift or pump station and a force main is necessary to force the waste through the sewer system.


Sewer treatment plants treat sewage from domestic homes and commercial and industrial buildings to deliver cleaner, more environmentally friendly effluent. The plants provide preliminary and secondary treatment to wastewater. Treatment includes but is not limited to mud and sand settling into a grit chamber, solids settling out into the primary settling tanks, and oxygen added to wastewater to enhance the growth of micro-organisms. Once the microbes consume the waste, up to 90% of human waste and solids are removed from the wastewater. The remaining wastewater is disinfected before it is deposited into local waterways.
