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 water everywhere … 30% toilet flushing 35% showers and baths 10% kitchen and drinking 20% laundry 5% cleaning
The Three Rules of water conservation and efficiency Reduce Repair Retrofit
WHAT CAN YOU DO … in the kitchen? 10% Reduce Repair Retrofit
Reduce Automatic dishwasher? full loads energy-saver setting Wash dishes by hand? fill the sink/pan only partially and rinse in another pan
Reduce Keep a bottle of drinking water in the fridge Don’t thaw food under a running tap Steam vegetables
Retrofit Install… water-efficient faucet aerators Think twice… before installing a home water treatment system water conditioning water filtration
WHAT CAN YOU DO … in the bathroom? 65% Reduce Repair Retrofit
Reduce Turn the tap on only when you really need water Don’t let the water run while you are doing things like brushing your teeth, shaving, etc. Consider an automatic faucet
Reduce Take a 5-minute shower Retrofit Install a low-flow showerhead aerated non-aerated
Reduce Half full should be enough Careful with the hot water!
Reduce Don’t use your toilet as a garbage can Repair Toilet run-on Leaks 6 L 18
Retrofit RETROFIT 18-litre6-litre Quick fix for now... water displacement device (plastic bag or bottle) water retention device (toilet dam) Best solution... install a new 6-litre toilet (low-flow model)
WHAT CAN YOU DO … in the laundry room? 20% Reduce Repair Retrofit
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 watering can 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 ABOUT 200 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 (Household with 2 adults)
Every Drop Counts … Behaviour Change Retrofit 18 L6 L For example… In the bathroom Before 18 L each 20 L/min. toilet flushes showers After 6 L each 9.5 L/min.
