Waste less water shut off the water when it’s not being used
What do we mean by water conservation and efficiency?
Use water more efficiently use less water to do the same job
Stop misusing water don’t use it for the wrong purpose
We can save watereverywhere …

Reduce and Retrofit
Washing Machine Wash full loads Use the shortest cycle Adjust the water level Use warm water
Hot Water Tank Set the thermostat at
50°C and insulate Install a heat trap
Consider a point-of-use water heater
Reduce and Repair
Piping System Use meter readings in off-hours to detect leakage
Repair leaks
Keep pipes from freezing
Stop
!
Misusing the sink drain … for household cleaners, paint, solvents, pesticides, and other chemicals.
Store and dispose of hazardous products properly… Never pour them down the drain!
Buy only the environmentally hazardous products you really need and only in quantities you will completely use up.
WHAT CAN YOU DO … outdoors?
REDUCE REPAIR RETROFIT
Remember: Outdoor water use increases water consumption by 50% or more
Retrofit
Switch to low maintenance landscaping
Consider native vegetation
Replace grass with drought-resistant plants and ground cover
Use interlocking paving stones for walkways and patios
Reduce Don’t over water (2-5 cm/week;
at most every 3-5 days) Water in the coolest part of the
day (early morning) Use a sprinkler that delivers BIG
droplets (instead of spray) Water the lawn (not walkways
and roads) Use an automatic timer on the
sprinkler Leave grass at least 6 cm long
Reduce
DRIP DRIP DRIP
One real soaking beats several quick wettings
Deliver water slowly (3 drops/second)
Water the roots, not the leaves
Reduce Use rainwater
(from your rain barrel)
Use a wateringcan on flower and vegetable gardens
Use compost and mulch in your garden
Reduce Use a bucket and sponge to
wash the car
Use a trigger nozzle to rinse
SAVE ABOUT 300 LITRES OF WATER… each time !
Reduce
Use a broom to clean your driveway or sidewalk
SAVE ABOUT200 LITRES OF WATER… each time !
Reduce Use a pool cover
Check equipment for leaks
Keep the water in the pool... don’t overfill
WHAT CAN YOU DO… to keep track of water use?
Read the meter(if you have one)
Keep a water log
Pinpoint areas where water savings can be achieved
Water Log …
using average consumption figures
no big water users (e.g., swimming pool, big garden, etc.)
Result: > 200 L/day/person
with water efficiency
