Water Extraction

“We never know the worth of water till the well is dry.” ~ Thomas Fuller, 1732

The City of Charlottetown uses the Winter River watershed as it’s primary source of municipal water. A small amount of water is still sometimes pumped from the old Malpeque pumping station (1888) located within the City of Charlottetown during times of peak demand. Over the years three wellfields were developed in the water shed: Brackley (1930), Union Road (1949), and Suffolk (1994).

However, the amount of water that is being extracted each year is too high. Local residents and the watershed group have noticed troubling evidence of this over extraction:

  • Dry streams in 2001, 2011, 2012, 2013, 2014
  • Springs stop flowing
  • Fish stocks are decreasing
  • Farmers in the area not allowed to irrigate crops

A new water extraction policy has been developed that is based on reductions in the water flowing in nearby streams. Water extraction shouldn’t reduce the flow of water in the stream by more than 35% in an average summer. This policy is supposed to be more conservative of the water resource. However, we still have questions about how it will work in practice, since the City pumps water from the Winter River all day, every day, the only way to determine what the stream flow would be naturally is through computer modelling. In several recent years streams have gone completely dry, which would be a 100% reduction in flow – so an improvement would be welcomed.

The previous guidelines for water extraction were based on the amount of precipitation that generally falls in an area each year. A sustainable amount of water extraction was deemed to be 50% of all the precipitation that falls in a year, called 50% of recharge. This policy is the one our association is more familiar with and have used in our watershed management plan. From the graph below, it is clear that the City has been extracting more than this guideline. So reductions in extraction by the City will be needed to conform to either the old or the new provincial water extraction policy.

  • Since the new policy should be more restrictive in most cases, and it is hard to determine what an average summer stream flow would look like in the river without the extraction by the City, we will continue to use the 50% recharge values for illustrative purposes.

However, due to a grandfather clause, the City does not currently have to follow either of these policies. They are allowed to continue to take the same amount of water that they have been taking for years.

The Government of Prince Edward Island permits the City of Charlottetown to extract water at an unsustainable rate. In the City’s permit from the province, effective October 2010, it was stated that as no previous permit had been in place, the current permit would be based on the average daily pumping rates that approximately match the usage in 2009.

A new wellfield at Miltonvale Park is scheduled to start supplying water to Charlottetown in 2016 (click for reference). This will reduce the stress on the Winter River, however, that is still years away. Also, if consumption continues to increase, and the City keeps growing, before too long yet another water source will be needed.


Water is being extracted beyond its capacity to recharge, and to support its ecosystem, but we have solutions.

City Residents can…

Watershed Residents can…

The Government of Prince Edward Island can…

  • Introduce a strong Water Act which has a clear definition of sustainable water extraction, and hold the City of Charlottetown accountable to comply with the Act.
  • Strictly enforce other environmental rules and policies, such as crop rotation rules.

The City of Charlottetown can…

  • Develop a comprehensive policy and programs that result in significant water use reductions by residents and businesses.
  • Set annual targets for water reduction, so progress can be gauged (which we have long advocated).
  • Implement the Water Shortage Restrictions in a timely manner during dry weather.

Water Use by Cruise Ships

On August 6, 2014 city councillor Rob Lantz tweeted “Harbour Authority 2014 report: revenue from H20 = $33436. Sold @ $1.75/cubic meter = 19106 cubic m. Equivalent to abt 75 single family homes.”

Comparing the water used by cruise ships to the total water used by the City, shows that cruise ships use about 0.3% of the City’s total for the year.

  • 19,106 for cruise ships in 2014
  • 6,905,928 for whole city in 2012 (this is the most recent data that has been provided to us).
  • Units are cubic meters. One cubic meter = 1,000 litres.
