Project Name: Waste Discharge Area Grading Piping and Spray Field Improvements
Owner: City of Plymouth
The Waste Discharge Area Grading Piping and Spray Field Improvement project increased the capacity and efficiency of the City of Plymouth’s wastewater treatment and disposal facilities and assisted the city in meeting the requirements for the discharge of treated wastewater. This included constructing containment levees to control runoff from the City’s waste discharge areas, excavation and embankment work within the existing treated effluent reservoir. Modifications were made to the outlet structures at the reservoir dam, demoing existing waste discharge area spray field, installing new spray field system including new PVC main and lateral piping and control valve vaults at each spray zone. Additionally, the project included access road reconstruction, new culvert crossings, erosion control, hydroseeding and environmental mitigation.
