Update Study - Weeping Tile Disconnections
Presentation:
City of London - Pollution Prevention Control Plan Presentation (PPCP)
Ashley Rameloo (Director of Water, Wastewater, and Stormwater) and Kyle Chambers (Division Manager of Sewer Engineering) joined the LSTAR Board of Directors meeting on February 19 and presented an overview of the City of London’s Pollution Prevention Control Plan (PPCP). The objective of the study is to develop an implementation plan for a long-term solution that will limit the volume and frequency of Combined Sewer Overflows (CSOs) and Sanitary Sewer Overflows (SSOs) into local tributaries.
A number of options were considered, as outlined in the presentation, and the recommended mitigation strategy was weeping tile disconnection. There are currently between 40,000 and 50,000 homes in London with weeping tiles connected to the sanitary sewer system. This places significant pressure on the system and increases the risk of basement flooding during extreme rainfall events. The City has had a voluntary disconnection program in place for the past five years, offering a rebate of approximately 90% of the cost. Unfortunately, this program has seen only about a 1% participation rate, so they are considering a mandatory point-of-sale program. This could significantly impact LSTAR members and their clients, so we will be monitoring the progress of this proposal closely and will keep members updated.
