John Story | QA/QC – Wastewater coordination with NYSDOT, NYSDEC, and USACE for inspection, sewer cleaning, standard operating crossing Gott Creek, and the use of open cut and procedures, root control, wet weather operating plan, trenchless auger bore installations. The project aims and emergency overflow response plan. to reduce surcharging in the Dodge Road Interceptor and support future development with minimal Lift Station 8 Discharge Forcemain disturbance to residents and businesses. Upon Project Manager | completion, the parallel interceptor sewer will Town of Grand Island | Grand Island, NY, USA enhance sewer capacity and support growth in Clarence and ECSD No.5. As part of an Order on Consent with the NYSDEC to evaluate and abate SSOs, John has been assisting the Wastewater Facilities Plan and Sanitary Sewer Town to identify and remove iI/I sources for the past Overflow (SSO) Abatement Plan 10 years. GHD was retained to evaluate the hydraulics of the system and review alternatives to increase the Project Engineer | size of the LS-8 forcemain, which was originally Town of Grand Island | Grand Island, NY, USA constructed in the mid-1970s and had reached the Evaluation of the existing collection system and end of its service life. The existing 16-inch diameter 3.5 mgd wastewater treatment plant in accordance asbestos cement pipe (ACP) was limiting LS-8 from with an order on consent issued by the NYSDEC for pumping at full capacity, resulting in frequent backups the elimination of SSOs. The evaluation included a and discharges. GHD recommended replacing the 16- capacity analysis of the collection system and WWTP inch ACP pipe with a 20-inch diameter PVC based on projected year 2030 flows and loads. forcemain. The new forcemain alignment totaled Alternatives were developed to eliminate SSOs in the 10,350 linear feet and included work within the New system; including pump station upgrades, new sewers, York State Thruway Authority property, crossings sewer repairs, and identification and removal of wet beneath high-pressure oil and gas lines, cased-bore weather I/I sources. Temporary flowmeters were stream and road crossings, and open-cut excavation utilized to prioritize mini-systems most prone to I/I. A within National Grid’s high voltage transmission line model was developed to estimate the effectiveness of easement. The project also involved three new each alternative toward the goal of SSO elimination. A interconnections, including a deep excavation phased sanitary sewer evaluation survey (SSES) work protected with steel soldier piles and timber lagging, plan was developed to prioritize I/I removal and and a vortex flow insert to mitigate hydrogen sulfide collection system improvement projects over a 10-year off-gassing. Several air relief chambers were included planning horizon. along the forcemain route for pressure testing. The project was substantially complete and operational by Collection System Evaluation July 2020.
