2. Ashoka windows
Apartment of 111
flats
With all amenities
like gym,party
hall, swimming pool
etc

3. COMMITTEE
 We are committee of 13 members
 Each member has their own department
 Department includes
security,HK,generator, lift etc
 We meet every week to update the status of
each department

5. NEED
 Cost reduction on maintenance
 Examined the major expense factor
 70% of total expense was towards water
 Explored various ways to reduce cost
 Never worked around less than 65%
 Needed a means to measure water usage

6. CHALLENGES
 Logical
 To convince people the need of water usage
measuring system
 Collecting the money towards it
 Technical
 Which kind of system to install
 Whether the system will be foolproof
 Individual flat usage to be recorded
 How to re-lay the existing plumbing system

7. STUDY
 Visited several apartments and decided to go for water
metering system
 Due to building architecture ended up with three
meters per flat
 Installation cost and maintenance overhead
 Did a detailed study and came down to one meter per
flat
 How to improve the life of meters
 overcoming water hammer effect increases life
 Usage of Y strainers
 Usage of u tube principle
 Cost per flat calculated
 Return on investment(ROI)

8. U TUBE Implementation

9. APPROVAL
 Called for an SGBM
 Detailed the needs and the study conducted
 All the existing GI pipes will be replaced
 Improved water flow to every floors
 Each flat owner will be responsible for their own
usage
 Water disruption will be one day in one line per flat
 Disconnecting the water to maintenance defaulters
becomes easy
 Within 20 months of operation the investment can
be taken back

10. PLANNING
 Estimated the materials needed for all flats
 Explored different quotations for the materials to
be used
 Negotiated with different vendors for quotes
 Prepared a schedule for the entire apartment
 Sketch showing how the pipes to be laid
 Planned to protect the meters physically from rain
and suns
 Planned to handle the water disruption during the
process
 Planned to charge the residents for their usage

11. PRECAUTIONS
 Money
 Whenever we reach a collection of 3L we FD the
amount for 7 days with auto renewal
 This will yield us interest as well safety to the
money collected
 Risk
 Risk of life in involved in this implementation
 We insured the plumber working with us
 Provided helmet for his safety

12. IMPLEMENTATION
 Started one section as prototype.
 One week time for residents feedback
 After consolidating the feedback, started the
full phase.
 Had an xls to monitor the daily usage of
materials
 Informed water disruption to the respective
flats everyday before starting the work.
 Guided the plumber to do as per the drawing
 Continuously monitored the progress

13. IMPLEMENTATION continued
 All pipes were laid 6” above the terrace floor
to allow rain water to drain
 Provided support to all the pipes with bricks
 Constructed a chamber for all meters to
safeguard them

17. MAINTENANCE
 We have 4 spare meters in case any meter
malfunctions
 Recorded the meter readings for one month
 Calculated the unit price per litre
 Arrived at an average usage per flat per
month
 A tariff has created being the average as pivot
 Flats usage crossing this pivot will be charged
double the unit price

18. MAINTENANCE continued
 Meter reading will be recorded every 15 days
 Every month bills will be generated on the
actual usage per month + base cost
 Base cost includes expenses for other
operations like security, house keeping, AMC’s
etc.
 Bills will be dropped in all mail boxes before
1st of every month
 The maintenance should be paid before 5th of
every month
