Water Supply Master Plan update

The City is updating the 2014 Water Supply Master Plan (WSMP) to review our water supply sources and identify priorities, including where our water supply will come from in the future.

The updated WSMP will provide short-term, mid-term and long-term water supply options to ensure we can continue to meet the demands of Guelph’s growing population. We’ll investigate existing and new water supply options – like new groundwater and surface water sources in and outside of Guelph – and consider things like water quality and quantity, climatic conditions, economic factors and any relevant regulations.

When we’re done, we’ll have identified constraints and opportunities related to our existing water supply system. We’ll also have evaluated and prioritized individual projects to increase the capacity of our existing water supply system.

Your input is an important part of this process.

  • How have the projected future water demands been considered with the current and future capacity of the Guelph WWTP? Realistically, it seems unlikely that water reclamation efforts would be implemented fast and vastly enough to keep up with the growing water demand (and consequent increased wastewater production).

    The Water Supply Master Plan is integrated with the Wastewater Master Plan through the water demand forecasts. The water demand forecasts are based on the number of people in Guelph by 2041 and how much water they will use during the same time period. 

    The water demand forecast is used in the Water Supply Master Plan to determine how much new water is needed and when it is needed in the future. Similarly, the water demand forecast is used as an input into the Wastewater Master Plan since most of the water demand ends up as wastewater. The Wastewater Master Plan then identifies alternatives to address the future wastewater treatment requirements as well as improvements and upgrades to ensure that there is existing wastewater treatment capacity when it is needed. 

    The Wastewater Master Plan will be updated in 2020, similarly to the Water Supply Master Plan. Interested persons should watch the City News for more information on the Wastewater Master Plan.
