South London Wastewater Servicing Study

Study Overview

The Wonderland Wastewater Pumping Station, located on Dingman Drive, just east of Wonderland Road South, directs sanitary flow from the City’s south end to the Greenway Wastewater Treatment Centre. The Wonderland Pumping Station does not have sufficient capacity to service the anticipated residential and industrial growth in the area. As a result, the City of London has completed a Municipal Class Environmental Assessment (EA) Master Plan Study to evaluate alternatives to address wastewater capacity constraints along the Dingman Drive/Wonderland Road South servicing corridor.


The Process and Outcome

The EA study was completed in accordance with the Ontario Environmental Assessment Act, and followed the Class EA Master Planning process (Approach #2) which fulfills the requirements for Schedule B projects. Two Schedule B projects were identified for the Preferred Solution:

1. Increase pumping capacity to Greenway Wastewater Treatment Centre by constructing a new pumping station complete with preliminary treatment adjacent to the existing Dingman Creek Pumping Station.

2. Provide additional wet weather storage capacity by constructing a new storage facility east of the existing Dingman Creek Storage Facility.

Prefered Option for Master Plan Study to determine a strategy
