Every resident in Carlisle relies on the aquifer for well water, whether it comes from a municipal well or a private well. Water storage is important to well-based communities for many reasons, including its ability to fight fires. Currently, the need to increase water storage has become an issue in the Carlisle community.
The Carlisle Conservation Committee (C3) is made up of 16 members including local Carlisle residents, City employees, a consultant and Councillor Judi Partridge. The purpose of the Committee is to research and promote water conservation and water efficiency in Carlisle. As a committee we feel that we can manage this issue and are looking for conservation based alternatives to building a costly new water storage facility. Using less water will also have a positive impact on our aquifer.
We need to maintain adequate fire water storage in Carlisle based on the adopted standard for fire flow 365 days each year. To achieve this goal residents of the 600+ homes on the municipal water system need to reduce their daily water usage to stay below the community total of 1,170,000 litres (1,170m3) per day.
Water usage during the summer months in Carlisle is very high. Many communities average a 20% to 50% increase in water usage during the summer months, however in Carlisle the summer water demand increases by over 160%. This increased demand compromises your community’s fire water storage. In 2015, there were 51 days in the summer where we did not meet the City adopted standard for fire flow that is based on the Fire Underwriters Survey. An additional storage facility will need to be built unless the summer water usage can be reduced to an adequate level.
Historical water usage
The graph below illustrates the historical summer water use in Carlisle from 2009 - 2016 . The different coloured horizontal lines (each colour represents a different year as indicated on the legend) on the graph indicate the amount of water used measured in cubic meters (1 cubic metre = 1,000 litres). Everything above the red line represents occasions where our community exceeded the adopted standard for fire flow. This happens primarily during the summer months and is believed to be a result of irrigation and watering practices. It is our goal to stay under the red line.
The Solution - What You Should Do
Do not be a water waster. Please visit the links below for more information on how you can support your community through water efficiency and conservation efforts. You have the power to help reduce the need for additional water storage and maintain fire protection levels, while also potentially enhancing aquifer water levels. Be a part of the solution and help Carlisle reach its goal.
