But, PPP is not only about large
investments or development of large
project facilities….
It’s about Prioritizing Objectives….
Most Indian cities aim for:
• Service improvement: 24/7 supply, good quality
water, equitable distribution in the city
• Increase the revenue (independent of tariff
increases) and improve the local employees’
skills to achieve self-sustainability
To achieve these objectives, a multi-process approach
is essential

Objectives…
Systematic Diagnosis: 38 Individual Processes
A City can prioritize specific actions according to their objectives
Illustration 1: Processes to improve water distribution
Construction of new network is often required but it is never enough
to achieve distribution improvement
Illustration 2: Processes involved in increasing revenue
by decreasing Physical and Commercial losses
Decrease Physical losses
Decrease commercial losses

Network Modeling & Equitable Distribution
Objective: Build and calibrate Hydraulic Numerical Model
(HNM) to achieve Equitable distribution across hydraulic
zones
 Analyse the existing hydraulic zones, including their network
configuration and water demand
 Defining the Service Levels
 Building the Hydraulic Model for the Primary Network
(from the MBRs to Service Reservoirs)
 To suggest measures for pressure management in the existing hydraulic
zones or redefined hydraulic zones.
 Develop management rules for Operating staff to achieve equitable
supply in the various hydraulic zones
Invisible Leak Detection
Conventional Method - Acoustic Detection (Based on three basic
Principles/ Requirements)
•
Requires water in the system to create noise at leak point
•
Requires high pressure in the system to detect leak noise
•
No Background noise Interference: Preferable to be carried out during Night Time, as
detection is affected by background noise
Advanced Method – Helium Gas based Detection (Suitable for Indian
Conditions of Intermittent Supply)
•
Leaks can be detected even during period of ‘No Supply’
•
Leak detection possible even in low Pressure
•
Detection can be carried out any time of the day
•
Accurate pin-pointing of leak is possible

Helium Leak Detection – Results Worldwide
 Helium based water leak detection
 Regular practice in Suez Group for last 6 years.
 Technique is also used in France, Middle East, South East Asia, Central America,
and now started in Delhi, and Pimpri-Chinchwad
 Leak Strike Rate is above 85% (Best compared to other techniques)

Smart Metering Solutions & Online Network Management
Objective: Smart network management using combination of
AMR , Network meters & SCADA

Monitoring of Network performance

Online Information to the customer

Leak and fraud detection

Leak Alert

Billing accuracy (removing human error)
We recommend Fixed Network AMR System
 This is a management tool and not just
substitute to meter readers
 Optimized Network Management
 Large network management analysis
 Real billing and no more estimation,
avoiding billing disputes
 Allows a fastest leakage detection, frauds
and default meters
 Monitoring with AMR drives a better
individual consumption
 AMR system can save 5 to 10% water
volume produced

PPP is not only about large investments or development
of large project facilities
…PPP frameworks can also be adopted for efficient and
cost-effective solutions
