NFE provided the City of Pontiac with preliminary engineering and construction engineering for the administration of this roof drain and downspout disconnection project throughout the City of Pontiac. The purpose of the project was to reduce wet weather flows in the City’s sanitary sewer collection system and at the City’s wastewater treatment plant by rerouting roof drains connected to the sanitary sewer to an approved storm drainage outlet. Because this project was instrumental in eliminating or reducing the severity of sanitary sewer overflows (SSO) to the Clinton River at the City’s wastewater plant, it was approved for Surface Water Quality Initiative Funds (SWQIF) from the Michigan Department of Environmental Quality (MDEQ).

Preliminary engineering services included: assisting the City in the preparation of the SWQIF Project Plan and Funding Documentation for approval by the MDEQ; identifying buildings in the City with roof drains connected to the sanitary sewer through visual inspection, smoke testing and dye testing; and preparing plans, specifications and proposal documents for bidding in accordance with Michigan Department of Environmental Quality requirements.

Construction engineering services included: contract administration, construction engineering supervision, construction/technical observation (inspection), construction layout and construction staking, on-site quality control and material testing, preparation of pay estimates, preparation and evaluation of punch list work, final inspection, review of documentation for final payment, and recommendation for final acceptance of project in accordance with Michigan Department of Environmental Quality guidelines and requirements.
