Outdoor Water Conservation
Most of our precipitation occurs during the winter months. Records with Environment Canada indicate that, on average, our area receives only about 100 mm of precipitation during June, July and August combined. This is less precipitation than areas of the Okanagan Valley during the same period.
Summer is also the time when the demand for water resources is highest. Consumption can increase by more than 50 percent over winter use. Most of this is used to 'inefficiently' water lawns and gardens. By trying to conserve water outdoors, we can reduce our impact on the water system during the summer months.
WaterSmart Tips
Rainwater Collection
- Collect rainwater in a barrel, cistern or water-features to save for use in drier conditions.
- Rainwater is at a more ambient temperature for your plants and it's free!
- Collecting rainwater helps reduce the amount of toxic run-off that enters our storm drains and eventually our streams and ocean.

Lawns
Up to 65 percent of water used to irrigate our lawns and gardens is lost to inefficient watering practices which result in runoff, evaporation, or leaks. To help prevent this:
- Aerate your lawn & top-dress with compost to improve water penetration and retention.
- Water deep but infrequently to maintain a healthy root system.
- Inspect your system frequently to make sure there are no leaks.
- Let your lawn go 'dormant' or golden in the summertime. It will go green again with the Fall rains.
- Reduce your turf area if you can - consider planting native species to 're-wild' your landscape.
For more tips, see the Team WaterSmart Healthy Lawn Care Brochure.
Trees, Shrubs, and Plants
- To reduce losses due to evaporation, water early in the morning.
- Consider installing water-efficient irrigation such as bubbler or drip systems that deliver water right at the base of the plant.
- Mulch around plants with straw, leaves, or live groundcover to conserve soil moisture and moderate soil temperature.
- Increase water retention of your soil by adding compost - this will improve soil structure and support healthy microbes.
- Prevent flowerpots & hanging baskets from drying out by adding a perforated plastic liner.
Vegetable Gardens
Maintaining a vegetable garden through a drought can be a challenge. The principles of xeriscape can lend themselves very well to growing vegetables during periods of limited water supply.
Here are a couple more tips:
- Excessive watering leaches nutrients out of the soil, encourages diseases and reduces flavour; consider a drip irrigation system.
- When planting water-loving plants such as tomatoes, line the soil with a thick layer of newspaper to maximize water retention.
- Practice companion planting by placing plants with similar water requirements close together.
General Conservation
- Wash your car using a bucket of water, a sponge and a hose fit with a shutoff nozzle.
- Use a broom instead of water to remove debris from paved surfaces.
- Cover swimming pools when they are not in use to reduce evaporation, consider a water-saving pool filter.
Residential Irrigation
Up to 65 percent of water used to irrigate our lawns and gardens is lost to inefficient watering practices which result in runoff, evaporation, or leaks. Learn all about regularly maintaining your irrigation system from our Top 10 Irrigation Tips brochure.
Irrigation System Check-Ups
Checking your irrigation system can help you catch leaks, lowering excessive watering times and saving water. We often offer workshops to encourage people to inspect their own systems.
Check out our upcoming workshops and if you'd like to check your own irrigation system, see our step-by-step guide to find out how!

Xeriscape Gardening
Xeriscape gardening is a systematic concept of saving water in landscaped areas - this means using fewer resources while still having a beautiful landscape. Practicing xeriscape can reduce water use by 70 per cent or more.
There are seven principles of Xeriscape:
- Plan and design for water conservation and beauty from the start.
- Create practical turf areas of manageable sizes, shapes and appropriate grasses.
- Use appropriate plants, such as native plants and those with low water needs will allow maximum water conservation.
- Soil improvement: your landscape will benefit from the addition of sphagnum peat moss, compost, aged manure or other decomposed organic materials.
- Use mulches to cool soil, minimize evaporation, reduce weed growth, slow erosion and provide landscape interest.
- Water wisely by considering the efficiency of your system, when you water and how frequently.
- Good maintenance by keeping your watering system free of leaks, mowing, weeding, pruning and fertilizing on a regular basis.
