BACKGROUND

The City of Ithaca (City) owns and maintains an extensive sanitary sewer collection

systems that consists of approximately 85 miles of 4” to 42” sewer main, which

includes roughly 1.3 miles of 1.5” to 8” sewer force main, approximately 2,370

sewer manholes, and 13 sewer pump stations. City sanitary sewer collection

systems that serve the West Hill, Inlet Valley, South Hill, East Hill areas immediately

north and south of the Cornell University Campus, and the Lake Street area

discharge to interceptor sewers (Interceptors) jointly owned by the Town and the

City of Ithaca. Metering manholes that contain flumes and level sensors are located

at most of the transitions from Town sewer mains to Interceptors. This

infrastructure serves approximately 35,000 City and 23,000 Town of Ithaca

residents.

Wastewater from these systems is treated at the Ithaca Area Wastewater Treatment

Plant (IAWWTF), which is jointly owned and operated by the City of Ithaca, Town of

Ithaca, and Town of Dryden.

Flows within most of the collections systems are influenced by the influx of students

when Cornell University and Ithaca College are in session.

Flows from the North East portion of the Town flow into the Village of Cayuga

Heights (VCH) collection system. This system then conveys the sewage to the VCH

treatment facility. A sanitary sewer bypass is located on Kline Rd in the VCH which

allows for a wet weather bypass during high flow events to divert sewage within the

VCH system to the IAWWTF.

Mapping containing additional information can be found in Exhibit A.

*Existing drawings may be reviewed upon request

PROJECT SCOPE

The intent of the project is to determine the Interceptor component capacities from

the Town/City municipal boundary to the intake at IAWWTF. This information will

be used to determine capacities for new developments and aid in developing a

capital improvement plan.

The anticipated scope of the project would include the following:

• Perform metering immediately below boundary meters to verify accuracy of

boundary meters.

• Perform calculations to determine Interceptor pipe capacities. There are pipe

segments that do not have information. Field work will be required to gather

this information.

• Perform metering throughout the various Interceptors to determine existing

average and peak flows within pipe segments. Metering shall occur when the

colleges are in session.

• Duration and location of meters to be discussed prior to submitting a

proposal.

• Review operation and capacities of jointly owned interceptor pump stations

and siphons with applicable standards for compliance (10 State Standards;

TR-16; etc.).

• Review results and complete a report documenting findings from the study.

Report shall identify percentage of Town and City flows independently

within the various Interceptors.

• Update shapefiles/feature layers with field collected data.

The following will be available/provided to the selected consultant:

• Traffic control for field work operations.

• Existing sewer system GIS data (data agreement required).

• Joint Interceptor Agreement

BUDGET AND TIMELINE

The City and consultant will finalize the total fee for professional services once a

consultant is selected.

The following is an anticipated schedule for the RFQ process. The Town of Ithaca

reserves the right to modify any part of this schedule:
