Pemberton water

The Village of Pemberton operates two water systems: the Village system and the Industrial Park system, and supplies water to the Pemberton North Water System (PNWS) which is owned and maintained by the Squamish Lillooet Regional District.

The main Village system withdraws water from the Pemberton Creek Fan Aquifer through wells. These wells  supply the entire Village of Pemberton population as well as meeting the demands of the PNWS. The Industrial Park system is separate from the Village system and is supplied with metered water from the neighboring Lil’wat Nation through a water use agreement.

For more information about key infrastructure within the Pemberton Water system view the Water Infrastructure Summary.

Water treatment

Since 2009, the Village has been chlorinating using sodium hypochlorite for both primary disinfection and to maintain the minimum free chlorine residual throughout the distribution system. Since 2017, the Village has also used soda ash conditioning to increase the pH and alkalinity of the well water to minimize corrosivity.

For the detailed report and full result listings, please refer to the most recent Drinking Water System Annual Report.

Water pH

The current Village of Pemberton water falls within the acceptable levels for pH as established by the Guidelines for Canadian Drinking Water Quality (GCDWQ). 

The following are excerpts from Health Canada Website and are meant to provide a very brief overview of PH levels in our drinking water.

There are no specific health effects on which to base limits for the pH of drinking water. The main purpose in controlling pH is to produce water in which corrosion and incrustation are minimized. These processes, which can cause considerable damage to the water supply system, result from complex interactions between pH and other parameters such as dissolved solids, dissolved gases, hardness, alkalinity and temperature.

Groundwater Protection Plan

The Village of Pemberton operates a wellfield to extract water from an aquifer for potable water supply. The wellfield consists of two primary wells and a backup well used in emergency purposes that supplies the Village of Pemberton and Pemberton North Water System (PNWS).

The Vancouver Coastal Health Authority issues the Permit to Operate the water system and has required that the Village prepare a Groundwater Protection Plan for their review as a condition of the Permit.
