Wateraudit school example

1. Water is life
Virtually everything we do or use each day involves
water. Yet, we do not give it the importance that is
due to it. India will soon be a water-stressed country
and we all need to work towards our water security.
Simple actions can be adopted to reduce the
wastage of water and use it wisely.

bills
• Water conservation helps our cities – Cities are stressed for
water resources.
• A water audit will help reduce wastage and unnecessary use.
• It makes the students more aware and responsible.
• A water audit can be a student project that encompasses a
number of subjects

14. FIRST STEPS- MEASUREMENTS
Estimate the quantity of water supplied from each source
Bore well and Dug well supplies…
1. Measure flow rate ( time taken to fill a 10 litre
bucket at the outlet of the pump.)
2. Keep a track of number of hours the pump is on in a
day (record every day of the week for two weeks).
3. Use these two to calculate the quantity of water
withdrawn

15. MEASUREMENTS- SUPPLY
Estimate the quantity of water supplied from each source
Municipal Supply
Tabulate monthly municipal water supply (from bills)
for the past three years in the supply tracking sheet
For tankers….
Using bills, tabulate the amount of water received
on a monthly basis using the supply tracking sheet
Tabulate consumption patterns and depict
using graphical tools

• Draw a plan of the school premises showing the building and main features.
• Mark the water supply inlets and storage tanks

17. FIRST STEPS- MEASUREMENTS
•Mark all water points (toilets, hand wash points, Sinks in labs,
drinking water fountains, canteen, irrigation taps, water meters,
pumps etc.
•Identify each point with an alphanumeric code
•Colour code freshwater and waste water lines
• Mark where the waste water goes.
• Mark the storm water drain system in the premises, if any.

20. Calculations :
water
consumption
• Can you meter water consumption at various inlet
points?
• Meters are expensive.
• Can you purchase one meter and use it in rotation to
monitor water use at different locations?
• If you cannot afford a meter, use surveys, observations
and calculations

INTRODUCTION

21. Calculations:
water consumption
Estimating Water use without a meter
Calculate the quantity of water that flows
out through each tap.
• Calculate the flow of water using a measuring jar
and a stop watch.
• Monitor / survey the time for which the tap is open
in a day.
• Fill this data in the consumption tracking sheet.

INTRODUCTION

22. Calculations: Water Consumption
• To calculate flow of toilets, turn off the water supply to
the toilet, mark the water line on the inside of the tank,
flush and then fill the tank with water from mug.
• Measure the volume of one mug and record number of
mugs required to fill water back up to the water line mark.
• Monitor / survey the number of times each toilet is used.
•Fill this data in the consumption tracking sheet.

Calculations:
water consumption
Estimating Water use without a meter
• Follow similar procedures to estimate water use at each water
outlet.
• The consumption tracking sheet will help you calculate the
total quantity of water used in a day.

24. AUDIT OBSERVATIONS

25. SUPPLY INPUT
Speak to the person in charge of the
water valves and pumps.
• Is water usage planned or is pump switched on when water
levels in the tank are low?
• What monitoring mechanisms are in place to check tank overflow?
• How often does the tank overflow?
• How much water is wasted each time the tank overflows?

26. FIXTURES AND FITTINGS
• At each water outlet point
make a note of:
• Type of fixture (dual flush toilet, capacity
of flush tank, type of tap spring-loaded /
screw type / lever, etc.)
• Notice condition of fixtures – dirty,
stuck, leaking, broken etc.

29. 28
Consumption of water in winter may be less
Consumption of water in summer just before the holidays
may be high
Rainy season – you might not consume water for
gardening purpose
Exams, Weekends and Holidays – water consumption
is likely to be less
29
Allow for variations due to the above reasons when
you are analysing the tabulated results

35. WAYS TO CONSERVE WATER
Garden
Keep a check on hoses in the garden
Try out efficient devices like the spray nozzles
Drip Irrigation
Plant native plants that require less water
Change the ground surfaces and vegetation to control run
off in the school grounds
Water the roots of the plant and don't splash water all around

36. WAYS TO CONSERVE WATER
Toilets and washing points
• Reduce the flush water volume in toilets.
• Replace single flush cisterns with dual
flush
• Install low flow fixtures for taps.
Install a rainwater harvesting system and use the
water for toilets, cleaning floors and gardening.

39. DARWIN ADVISES
• Analyze your situation
for the pieces that fit.
• Everything evolves, including
water conservation programs.
• Learn from other schools what
works and what doesn’t.
