Bordentown Sewerage Authority
Annual Report 2016
The Bordentown Sewerage Authority is providing this Annual Report to customers to update you on your investment in the community wastewater system.
As previously stated, Ocean Spray was a very intense water and wastewater system user who paid large fees to both agencies. The BSA has needed to raise rates to compensate for the $500,000 annual drop in fees. At the same time, the debt service on the long-term bonds is at its high point until 2020.
The staff and Board of Commissioners are dedicated to providing quality service to our customers in various ways. The BSA staff cooperates and shares equipment with the public works and water departments of Bordentown City and Bordentown Township. When extra hands are needed in an emergency response event, the cooperation between all three agencies is there.
It takes skilled and licensed staff members to operate the wastewater treatment system. Our staff is encouraged and rewarded for special certifications and advanced licenses.
Authority Response and Staff Training
Development means lots of new opportunities for citizens and a growing infrastructure. This translates into more maintenance and vigilance for staff. Getting the project underway with contracts, construction accounts, permits and engineering requirements means meetings with developers and site inspections. BSA staff spent 302 hours on this in 2016.
When other utilities dig near BSA lines, the staff must mark out our pipes. The Authority staff marked out 898 sewer lines, responded to 45 sewer blockage calls, and inspected 24 new or repaired sewer laterals.
The staff participated in the following training:
- Risk Management
- Hazard Communications
- Fire Extinguisher
- Collection System Maintenance
- Stormwater Pollution Prevention Program
- Confined Space Drill with emergency services to meet PEOSHA requirements
- Personal Protective Equipment
Thomas Redwood is now a C-4 operator and Administrative Manager Elizabeth Kwelty is a Qualified Purchasing Agent.
Authority Collection and Conveyance System
The sewerage collection and conveyance system consists of approximately sixty-five (65) miles of gravity sewers and force mains. The gravity sewers range in size from 6 to 30 inches in diameter, and the BSA owned force mains vary from 4 to 16 inches in diameter. The force mains convey flow discharged from sewage pump stations. There are fifteen sewage pump stations owned by the BSA and six that are privately owned. The overall system is reported to be in marginal to good condition. While the system functions adequately at this time, a portion of the gravity sewers, which were constructed in the 1910s are susceptible to infiltration which is stormwater runoff entering the sewer pipes. This is undesirable because it dilutes the wastewater and increases treatment costs.
Reduction of line infiltration
The BSA’s operating staff has undertaken corrective action in the past, which has reduced the amount of infiltration. Related to the infiltration prevention work, in fiscal year 2012, the BSA replaced approximately 110 linear feet of eight inch diameter sanitary sewer that was found deficit based on video work that was performed. In one instance at the intersection of Pine and Elizabeth Streets in Bordentown City, a large diameter storm sewer crossing over and existing sanitary sewer main was leaky noticeable through the sanitary sewer main joints. To correct this situation, the storm sewer pipe was provided support and this leaky sanitary sewer main was replaced resulting in an elimination of an infiltration source in the BSA collection system. Infiltration reduction remains as an area of concern with the operating staff and any infiltration sources uncovered are corrected.
At the present time, there is one developer constructed sanitary sewer/pump station/force main system in the project close-out stage. This conveyance system extension is being constructed to serve both Phases 1A and 1B of the Bordentown Waterfront Community. The system has been operational since late 2014 and was fully-dedicated to the BSA in late 2016.
Along Route 206 southbound between the NJTA entrance ramp and Dunns Mill Road there is an 8-inch diameter sanitary sewer which receives flow from the Rising Sun Road Pump Station force main and the discharged flow surcharges this sanitary sewer section. The surcharging over the top of sanitary sewer piping is less than 12-inches and does not overflow through the manhole frame and cover onto the ground surface. The BSA informed developers who propose to utilize this part of the system that it is their responsibility to construct a 12 inch diameter force main extension around the surcharging 8 inch diameter gravity sanitary sewer section. One developer agreed to undertake this work and the approximately 1,200 linear feet bypass piping extension was operational on March 4, 2016. The bypass force main discharges into a new 10 inch diameter PVC sanitary sewer section (185 lineal feet). This proposed piping was installed in 2013 due to a collapse in the existing asbestos cement sanitary sewer main.
Other conveyance system agreements the BSA has finalized in the past two years and their resultant progress is as follows:
- Along Route 206 where the sanitary sewer system enters the wastewater treatment plant site: A developer replaced 457 linear feet of 8 inch diameter pipe with 15 inch diameter pipe to alleviate surcharging. This sanitary sewer replacement work was completed December 2016.
- Rising Sun Road Pump Station Force Main: As noted previously, the existing force main was extended approximately 1,200 linear feet. Since this force main extension provided only limited capacity improvements to service a 1.4 million square feet warehouse facility and not the entire upstream service area, a developer has agreed to upgrade the existing 3,000 linear feet of 6 inch diameter force main with 12 inch diameter force main piping along with replacing the existing pumps and associated electrical components. These force main improvements have been designed and the NJDEP Treatment Works Permit has been received and should start construction 2017.
The BSA continues, as in the past, to utilize its Jet-Vac truck to clean all pump station wet wells.
On-going general pump station maintenance work such as painting, minor repairs and pump repacking has continued, as in previous years.
Finally, there are two (2) active pumps at the Mile Hollow Pump Station. A third pump has been inoperable for an extended period of time. When the budget permits the BSA will consider adding a third pump with its own control system as a backup system to supplement the existing emergency generator.
If you have any questions please call Richard Eustace the Executive Director of the BSA at 609-291-9105. The Board of the BSA meets on the third Monday of each month at 6pm, except for January and February, when the meeting is held the third Tuesday.
