Friar Lane Sewer Shed Project


During peak rain events, rainwater/groundwater enters into the sewer system through defects and prohibited connections. When capacities of the facilities are exceeded it can cause raw sewage to erupt from manholes, or backup into basements. Once conveyed to the treatment plant it can not be properly treated which results in poor water quality discharges into the stream. 

Since 1996 approximately $7 million dollars has been spent on capital projects to address this problem without true success in reducing the actual peak wet weather sewage flows.  Rehabilitation projects completed on public sewers did improve the infrastructure, but caused the water to simply migrate into the private sewer lines, therefore not eliminating the migration of ground water into the system.

The Authority is at a point of either continuing to spend millions of dollars in facility expansions to accommodate this infiltration or attempt to eliminate the groundwater from entering into the system.  For these reasons, the Authority feels it is necessary to implement a pilot program to gather more data and knowledge on the type of problems that exist within the private sewers and the cost of repairs. This will give management the data necessary to evaluate whether implementing an area wide program on the private sewers is a cost-effective solution to the wet weather problem.

Purpose of Project

To develop a comprehensive plan to equitably test private properties for, and to eliminate, RDII (Rain Derived Inflow and Infiltration) within sewersheds identified by engineering studies that contribute large amounts of groundwater into the sanitary sewer system.

Friar Lane was selected based on engineering studies of those sewersheds having the highest RDII being selected first.   From the Authority standpoint, the Area-wide testing is the only way to quantify results of the rehabilitation and the impact of RDII removal.


Realizing that if the Authority asked for the property owner’s cooperation, and then requiring them to make thousands of dollars in repairs, participation in the Pilot Program would be zero.  The Authority has determined that the only way to obtain participation of the majority of households is to fund repairs to the building sewer and building drain internally.  The Authority is planning to pay for all testing, repairs to cumulative maximum of $3,000, provide a stipend for those whose homes do not require repair, and pay for major restoration such as driveway repair or replacement.  All repairs will be on a case by case basis.

Project Status

We would like to thank all of the residents who took the time to complete, notarize and return the Right of Entry Agreements to our office. We have now formally achieved the minimum number of residents needed to move forward with the project.

Once the testing is completed, the Authority will review the inspections and bid repairs to contractors who will repair the defects. To help manage costs, the Authority may make simple repairs with existing staff.   It is anticipated that testing and repairs will be made in 2011 so we will be ready for post rehabilitation testing during the spring wet weather season.  It is anticipated that this will be a twelve month process.
