This document discusses water management and conservation. It notes that while water covers most of the Earth, less than 1% is available for human use. By 2025, water shortages are expected to affect billions of people, especially in Asia. Proper water management is needed to ensure sufficient supply. This involves metering, reuse, efficiency practices, and stormwater management. Tips provided include fixing leaks, running full loads for washing, using collected rainwater, and choosing drought-resistant landscaping. The document emphasizes the importance of conservation and controlling water usage and quality.

2. why water management?
♣Although more than 70% of the earth surface is covered in water less than 0.5%
fills the earth’s rivers and lakes and is available for domestic uses.
♣Research says that by 2025 the world population would be 8.3 billion and 2.8
billion would be with out water.
♣ Asia particularly India would be worst affected percentage of people would be
with out water as high as more than 40%
♣ due to the excessive withdrawing of ground water and nature unable to keepup
the demand, water table have dropped.

3. What is water shortage?

8. Water metering
There are two types of water charge
RUBS (Ratio Utility Billing System): Under this
system, residents or consumers won’t understand
the true cost or unit of water consumed by their
family members.
Sub –Metering:. This system enables residents or
owners to pay for the water they use rather than
paying a fixed amount..

9. Water re use
♣Grey water system
♣Black water system
Pipes and supply points on the re used water system must be
clearly labelled in order to avoid confusion with the mains drinking
water. Grey water systems can help you save 35% to 40% on your
annual water bill.

Wash laundry and dishes only when there
is a full load
Always turn off running water
Take shorter showers
Eliminate any and all leaks
Reduce the flow of toilets and
showerheads

13. A-Z WATER SAVING TIPS
A dripping tap could waste as much as 90 liters a week.
Brushing your teeth with the tap running wastes almost 9 liters a minute. Rinse
out from a tumbler instead.
Cool water kept in the fridge means you won't have to run the tap for ages to get
a cold drink.
Don't use your washing machine until you've got a full load. A full load uses less
water than 2 half loads.
Every time you boil an egg save the cooled water for your houseplants. They'll
benefit from the nutrients released from the shell.
Fit a water saving device in your cistern and save up to three liters a flush.

14. Grow your grass a little longer. It will stay greener than a close mown lawn and
need less watering.
Hoeing stimulates the growth of plants, reduces water loss from the soil surface
and removes weeds that take up valuable water and nutrients.
Installing a water meter can save you water and money by monitoring how much
you use.
Just taking a five minute shower very day, instead of a bath, will use a third of the
water, saving up to 400 liters a week.
Kettles should be filled with enough water for your needs but not to the brim. This
will reduce your fuel bills too.
Lag your pipes to avoid bursts and leave your heating on a low setting while you
are out in cold weather to prevent pipes freezing.

15. Mulch for moisture in the garden. Adding a layer of tree bark, compost, coconut
husks or even newspaper keeps the sun off the soil and retains precious
moisture.
No further watering is usually required for established trees and shrubs.
Once a week is all the watering your lawn needs even in the hottest weather.
Purchasing a water butt will help you to collect rain water for use on the garden.
Question your local garden centre about the water requirements of different
plants. Some thrive in drier conditions.
Replacing a toilet cistern can save water.

16. Sprinklers can be wasteful. A sprinkler can use as much water in an hour as a
family of four will use in a day!
Trigger nozzles can save water by using it only when needed.
Use the dirty water when cleaning a fish tank on your houseplants. It's rich in
nitrogen and phosphorus, which provides an excellent fertilizer.
Very 'water efficient' washing machines and dishwashers are now manufactured.
Water your garden at the coolest part of the day to reduce evaporation.
Xeriscape means to use plants that require less water.

17. You can use less water by turning the hot tap down, rather than the cold tap up, if
you require cooler water.
