This document proposes a water distribution management system using sensors to detect leaks and contamination. Stakeholders include residents and water suppliers. The system uses pressure, location, and chemical sensors along water pipes to detect leaks and contamination levels. When issues are detected, valves shut off the affected area, alerts are sent to command centers and field personnel, and residents are notified. A mobile app and command center dashboard provide real-time water quality data and outage information to users. The system aims to reduce water waste and health issues while helping suppliers improve maintenance.

2. WATER DISTRIBUTION PROBLEMS
A lot of water is wasted due to leakage.
Trouble caused to the residents due
contamination

3. STAKEHOLDERS
Residents
Need to know the status and quality of the water.
Suppliers
Need to know the leakage and level of contamination
of the water and the respective locations.

4. PAIN POINTS
Lack of information about water supply
and quality; and health problems with the
contaminated water.
Suppliers may not know the water
leakage location, level of contamination,
also lose revenue.

Where
P is pressure sensor
L is location sensor
S is shut valve sensor
Context Building Rules
If (P2
< P1
)
Then,
Water leak occurred between
P1
and P2
Actions
● Shut off valve at L1
● Raise alerts in command centres
● Inform field support person
● Inform residents in the affected
areas

Context Building Rules
If chemicals (Na, Fe, Mn, Ca) present
in higher concentration or/and
microbes are present then,
Water is contaminated
Actions
● Shut off valve at L1
● Raise alerts in command centres
● Inform field support person
● Inform residents in the affected
areas

Valve is manually closed when there is a huge difference in pressure which
would also be notified by a red light.

Quality-
The citizens can view the quality of
water anytime from the mobile app
Past Data-
Citizens can view the past data about
the water leakage and contamination of
water
Location-
Citizens can view the location of the
pipe burst and avoid taking the water if they
come under those areas
Call-
Citizens can call the water
supplier/plumbers

12. Benefits for the Users
● Always know the quality and
status of water
● Can avoid spending money
on RO water systems
● Can save water wasted using
RO systems
● They can stay healthy

13. Benefits for the Water Suppliers
● Can avoid routine checkups
and can depend on predictive
maintenance
● Can monitor water supply
and can act in realtime
● Can predict the pipe
replacement if needed in
future

14. Benefits for the Field Personnel
● Realtime information on the
incidents and the location of pipe
burst help save their time and effort
● It can also predict the future failures
and thus help them to be on top of
their work
