GPD Design Flow
Lakeville/Middleborough MBTA commuter rail opened a new station in 1997. Most of the commuter rail ridership drove to the station from the surrounding suburban area. There was also a need for additional local affordable housing in the area, however the lack of sewers prevented a development density that allowed for both market rate and affordable housing. Furthermore, land values put a premium on real estate in the area, so a compact solution was necessary.
- Enabled transit-oriented development adjacent to commuter rail station
- Compact system utilizing Membrane Bioreactor and Rapid Infiltration Basins
- Ultraviolet disinfection prior to groundwater discharge
- Design-build-operate delivery minimizes owner’s risk exposure
- completed in 2009
NSU designed, built, and operates a wastewater treatment plant serving a transit-oriented residential development, situated adjacent to the Lakeville/Middleborough MBTA commuter rail station. The 39,000 GPD single train facility, was sized to serve 192 apartment and condominium units. Membrane bioreactors are housed in compact 42’ x 32’ Building. Effluent is dispersed by means of open sand beds in compliance with the facility’s ground water discharge permit. Major effluent limits are: 30mg /L BOD; 10mg/L TSS; 10mg/L Total Nitrogen. NSU has operated this system since it was completed in 2009.
