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

Such PPP Structures can help in customizing offer to meet City’s 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

Cities can choose Services individually or in an integrated manner…

Individual and Integrated Services

Network Survey and GIS mapping

Customer Survey and Customer Database

Network Modelling Equitable distribution

Zoning and Pressure Management

Leak Detection & Supervision of Leak Repair

Smart Metering & Online Network Management (AMR)

Customer Relationship Management

Asset Registration Water Solution for Slums Areas

Quality Assurance & Reporting

Training & Knowledge Monitoring

These can be offered as individual services or combination of services depending on city’s needs and objectives

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

To Summarize…

Cities should prioritize their objectives and opt for specific ‘Services’ Projects in PPP mode

• Leak Detection and Repair (Reducing Physical losses) • Metering and Customer Services (Reducing Commercial Losses)• Primary Network Management (Equitable distribution across city) • Smart Metering and Online Network Management• Reducing NRW

Contract Period: 6 months – 3 Years

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
