The WaterWise program is an initiative of the Township of Langley’s Water Resource Management Strategy. It includes a public outreach and educational program delivered annually throughout the Township with the help of Langley Environmental Partners Society (LEPS). Since 2002, the WaterWise program has visited communities and neighbourhoods informing residents about the importance of local groundwater and providing practical ways to conserve and protect our drinking water supply.  

The WaterWise program:

  • Hosts free community workshops for residents on topics ranging from proper septic tank maintenance to management of private wells

  • Offers tools and economic incentives for residents to conserve water

  • Engages residents at their door and local community events

  • Provides elementary school level workshops and performances

Where Does Your Water Come From?

The water supply for the Township of Langley is quite unique for our region. 
Our clean, high-quality drinking water comes from two main sources:

Metro Vancouver Water District:  Rain and snow falls in drainage areas called watersheds up in the mountains of the North Shore and Coquitlam. This water supply is pristine, natural and protected. The watersheds are protected from urban development, closed to public access and managed as natural assets of the highest importance to the region we live in. 50% of the water consumed in the Township of Langley is supplied by the Metro Vancouver Regional District drawn from the Coquitlam Watershed. 

Groundwater:  50% of Township of Langley residents are dependent on groundwater, either through private wells individual property owners are responsible for, or municipal wells, for which the Township manages. Our groundwater resource is shared with many users, including agriculture, industry, and the natural environment. In some areas, it is being used faster than it can replenish.

Water Conservation Tips

The average BC resident uses about 465 L of water per day! Well above the national average of 329 L per day. That’s the equivalent of about 118 4 L milk jugs per day! It’s time we challenge ourselves to conserve this precious resource. To find out how to reduce water use, both inside and outside the home click here.

WaterWise Gardening

Did you know that we use our drinking water to flush our toilets and water our lawns and gardens? Township of Langley residents and businesses use 12.8 million m3 of water each year; equivalent to filling 5,120 Olympic sized swimming pools!

WaterWise Gardening means selecting and maintaining native plants that can survive long periods without water. These plants naturally use less water to stay healthy during months when rain water is limited, helping to reduce water consumption in the garden. There are many species of plants available at local nurseries that can thrive in our dry summer and wet winter conditions.

Examples of native drought-resistant plants can be found here.

The Invasive Species Council of BC provides a handy brochure called ‘GROW ME INSTEAD’  giving gardeners native drought-resistant alternatives for common garden favourites.
