What can we do to teach people to save water?

- Don't draw off more water than you require.
- Never rinse your hands, clothes or vegetables under a running tap.
- By taking a shower instead of a bath, you use only one fifth of the water
- Water CAN be used again. Save your bath slops to wash the floor or water the pot plants.
- Be economical with your washing machine and dishwasher. Save for a bigger wash and cut down the rinse cycle.
- A dripping tap can waste up to 70 litres a day. Get it fixed immediately.
- Teach your children that water is not for games

Notes on Water Saving Practice for Trade Consumers
1. Use manufacturing processes and equipment which ensure economy in water.

2. Determine water requirements for each unit of production and introduce control checks on usage.

3. Ensure that hot water pipe runs are as short as possible and that cold water pipes are laid clear of heated areas, heated equipment or steam-lines.

4. Reduce water pressure to the minimum practical level.

5. Carry out regular leakage tests on concealed piping and check for overflowing tanks, waste, worn tap washers and other defects of the system.

6. Recycle water to the maximum extent :
- water for cooling purposes should be pumped to a condenser/heat exchanger and cooled for re-use,
- rinsing water should be collected, diluted with fresh water and recycled,
- re-use steam by condensation.

7. Use reject water for secondary purposes - water from some processes is still usable for cooling purposes, floor cleaning and yard washing.

8. Draining, rinsing and spillage should be reduced to the essential minimum :
- ensure that bottles, cans, churns and other vessels are fully emptied of contents before washing,
- reduce spillage by keeping water level in rinsing and washing tanks to minimum,
- use counter current washing and rinsing methods.

9. Turn off system at night and during holidays.

10. Educate employees to save water by use of posters and other publicity materials.
