CIP - Sewer Fund

CIP - Sewer Fund

The Sewer Fund portion of the proposed CIP totals $1,589,000 in FY2022. More information about the first year requests can be found below. Refer to the CIP book for FY2022-27 for a complete list of proposed projects for fiscal years 2023 through 2027.

Transfer to Capital Reserve

Transfer of funds from the operating budget into reserve account for payment of future projects and equipment. To ensure adequate funding is available for facility and infrastructure upgrades without having large increases in water rates.

Cost: $500,000

Inflow/Infiltration Mitigation

During periods of heavy rainfall and snow melt, clean water enters the sewer distribution system and occasionally causes surcharging of the system resulting in the bypass of untreated sewerage to the Bellamy and Cochecho rivers. This storm water is known as "Inflow and Infiltration" and must be reduced. It enters the systems through leaking maintenance holes, pipes, roof leaders, basement drains and catch basins discharging to the sewer system.

Cost: $300,000

Pump Station Equipment Replacement/Maintenance

The City has several sewer pumping stations that require upgrades and replacements. These stations must continue to be in top operating condition to prevent violations of the City's National Pollutant Discharge Elimination System (NPDES) permit.

Cost: $78,000

Sewer Heavy Equipment Replacement

This fund is used to replace larger equipment within the Water and Sewer departments. Similar to the Police Vehicle Replacement program, some years have no equipment purchase, as the funds are allocated to larger purchases the following year. These vehicles are used to perform utility replacement at job sites.

Cost: $40,000

Sewer Light Vehicle Replacement

This funds the replacement of light vehicles, such as vans and pickup trucks, to transport staff and parts to job sites.

Cost: $15,000

Sewer Main Replacements - City Wide

There are section of sewer mains throughout the City that are in need of replacement due to cracks, collapse and blockages. Some of the first areas to be addressed are Atkinson Street, Hanson Street, Richmond Street, Grove Street and Central Avenue.

Cost: $156,000

Waste Water Treatment Plant General Permit Compliance

A draft National Pollutant Discharge Elimination System (NPDES) was issued by U.S. Environmental Protection Agency in January 2020. The NPDES permit is considered a General Permit for the reduction of total nitrogen reaching Great Bay. The permit is to include Adaptive Management, and its implementation will likely require extensive data collection, water quality monitoring, and studies to assess the recovery of the estuary.

City work will also be required to perform an Optimization Study of the Waste Water Treatment Plant, and a Nutrient Control Plan for the entire City.

Part of this project will update the ultra-violet light system. The effluent discharged from the wastewater treatment plant is disinfected with non-chemical addition, ultra-violet light. The current system will reach its 20-year design life in the calendar year 2023. This is a critical system to ensure safe and compliant effluent is continuously discharged.
City staff will pursue funding through the State Clean Water Revolving Loan Fund Program

Cost: $500,000
