Wastewater Alternatives Case Study

The Pinehills Development, Plymouth

The project was planned as an open-space mixed-use development (OSMUD) as an alternative to the standard subdivisions which predominate the region.  It serves as an excellent example of compact design, reduction of impervious surfaces, water conservation, wastewater re-use, and historic preservation.  The development site is in a rural area with no pre-existing public wastewater services.

Wastewater Plan:

To accommodate high-density development clusters (8 residential units per acre and a mixed-use village center) The Pinehills comprehensive sewer system delivers wastewater to a state-of-the-art treatment facility which has been careful sited hydrologically downgradient of the drinking water supply site.  Treated wastewater is discharged to the ground where it infiltrates to groundwater.  A series of re-capture/irrigation wells were then sited downgradient of the wastewater treatment plant to recover this treated wastewater after it is mixed with groundwater.  The recaptured groundwater has elevated result in the reduction of fertilizer applications.
