These revenues will cover the portion of the line that had to be redesigned for Hillsborough. The total project cost will be 1.5 million.

Alternates 3 and 4 are sized to accommodate the Efland area as it was originally planned and option 4 would include additional areas. Commissioner Hartwell asked about the increased capacity in going from an 8" pipe to an 10" pipe. Kevin Carter, Engineer for Hazen and Sawyer, explained that to pump 535 gallons per minute through an 8" force main requires 167 foot of head which is the limit that the type pumping system will take. A 10" force main would drop the flow rate from 535 down to 89 because portions of the 10" force main would be gravity driven. In power cost there would be a savings of approximately $26,000 or $27,000 over a ten year period. A 12"
