Leakage through pipelines – Reasons 7 Leakages may occur in water supply pipelines due to various reasons as shown in the diagram below. Leakage through pipelines – A Nuisance 8 A small leak in the middle of a road can cause tremendous trouble to the citizens. It disrupts traffic on roads. Less quantity of water to consumers than planned. Loss of treated water amounts to a considerable financial loss and therefore affecting sustainability of the system. A leak of only one litre per minute corresponds to 525,600 litres per year. Leaks increase operating costs A potential source for contamination of treated safe water Leakage Mapping – Objectives 9 Leakage mapping is necessary because normally; leakages repaired on a piece-meal basis. leakage repaired without attention to the root cause of the problem. Frequent leakages in a particular portion of pipeline requires special attention and suitable action to solve it in a sustainable manner. Preparing a map showing frequent leakage prone locations. Addressing the problem in scientific approach; gives sustainable results reduces complaints of leakage & contamination of water. Leakage Mapping – Need of the hour 10 The Ministry of Urban Development, Government of India has chosen the city of Surat among pilot cities for implementing Service Level Benchmarking for four urban basic services and it includes “Drinking water Supply”. To achieve NRW within 20% standard limit is an important parameter of Service Level Benchmarking (SLB), as suggested by MoUD and adopted by SMC. As a constant endeavour to achieve the targeted SLB, Non- Revenue Water (NRW) cell of Surat Municipal Corporation has started functioning. Leakage Mapping is an important activity of NRW cell, Leakage Mapping is a “No cost, Low Cost initiative” to bring down NRW. Leakage Mapping – Mechanism Flow-chart After Discussion with Frequent Leakage Fault Finding & Solution Leakage team/ Fitter Remedial Measures Implementation Frequent Leakage Mapping HQ-AutoCad – Monthly Review By Zones By Head Quarter By outsourcing (AMC) Pipe 550 -750 mm dia. Pipe < 550 mm dia. Pipe > 750 mm dia. Leakage Repairs Leakage Reporting: Leakage Complaint: •All Zones Report to HQ daily •Customer Complaint- Web/Helpline •HE reports to Comm. weekly •Departmental / Zonal leak detection team Water Pipeline Customer Complaints - Leakage & Contamination 12 Customers’ leakage complaints are generally related to ferrule level water connection. Customer can make a complaint by; Internet on SMC’s website www.suratminicipal.gov.in helpline phone numbers visiting nearest City Civic Center / ward office / zone office. Customer complaints regarding leakage/contamination of tap water attended within 24 hours. Customers are informed by email/phone when their complaints are resolved. Customer’s feedback is also taken to know their level of satisfaction Complaint Management System (web) Leakage Mapping – Methodology 14 Major leaks on roads are reported by; HQ NRW team /zonal teams of beldars from 7 different zones. officers, engineers on field visit, health workers working in the field All leakages are repaired promptly by; Fitter team of zones for water supply pipelines up to 550 mm dia. Fitter team of Hydraulic Department (HQ) for water supply pipelines from 600 to 750 mm size Outsourcing the job to private agencies on Annual maintenance contract for leakage repairs on all major water supply trunk mains/ transmission pipelines of dia. greater than 750mm. All 7 zones and Hydraulic Department (HQ) has; a dedicated team of beldars headed by a fitter (known as fitter team) a separate JCB machine & dewatering pumps for this job. Leakage Mapping – Methodology 15 All leakage complaints are registered by every zone in a separate register. All zones prepare a summarized statement of all leakages including; New leakages found, Leakages repaired on the previous day leakages under repairs All zones report daily in a standard format to Hydraulic Department at Head Quarter. Hydraulic Engineer prepares a summarized daily report of leakages for all zones.
