Blake Farm
Sanitary Sewer Narrative
The Blake Farm pump station is being sized to handle flow from a variety of different uses that
are proposed at the development. The proposed pump station will connect to an existing force
main that conveys sewer flow to the Waste Water Treatment Plant owned by Pluris
Hampstead, LLC.
The first phase of construction will consist of constructing the infrastructure for 136 townhome
units. The lift station will initially handle flow from the 136 townhome units and a proposed
pool/clubhouse. There will be 4,065 If of S" gravity sewer main and 190 If of 6" force main.
The pump station and force main is sized to handle flow from the town homes and future
apartments, a retail area and other future uses
