West Vaughan Sewer System (WVSS)

— Project Description:

This project involves a trunk sewer from the Kleinburg Water Pollution Control Plant (WPCP) to the Humber Sewage Pumping Station (HSPS) and to expand the existing HSPS from a capacity of 1,700 l/s to 2,400 l/s. The WVSS project includes a 14km-long series of sewer tunnels with associated pumping station overhaul and access shafts. The tunnels, with approximate 3m-inner diameter, will be excavated in glacial soil and soft rock using two earth-pressure-balance tunnel boring machines, also incorporating a segmental concrete lining. The project design will also take into consideration the protection of existing infrastructure and natural features.
