Pembroke, North Carolina The existing .82 MGD Pembroke Wastewater Treatment Plant was nearing the end of its design life and despite good maintenance it suffered from high influent flows during storms and could not properly handle waste-activated sludge. The plant was built on a small piece of land between a railroad right-of-way and the Lumber River. The existing site had no room for expanded facilities, but an adjacent field was available for purchase. A preliminary design decision was made to purchase the land so an environmental assessment of the expansion could include the impact of a land use change.
Project financing was initially sought and acquired through State Revolving Loan Funds, but the Pembroke 201 Facilities Plan had to be updated to secure the funding. An environmental consultant was hired to assess the biological impact of the proposed facility expansion. Alternatives were identified and compared. After the planning phase, designers decided to base the design on a 1.33 MGD hydraulic flow and provide a new treatment plant which would use the existing plant for sludge handling after the new plant was brought on line. |
