The City has implemented the Lisgar High Water Protocol (LHWP), whereby weather forecasts, and other relevant information such as High Water Bulletins from local Conservation Authorities, are monitored to identify more formative storms, including thunderstorms. During identified storm events,
the City implements a temporary pumping system at multiple locations within the Foundation Drain Collector (FDC) system as an emergency measure to provide relief from elevated water levels.

The HWP is reviewed regularly and revised as needed in order to achieve its goal of mitigating basement water infiltration in the community. The most recent iteration of the protocol is available through the link below:
