Solutions of Non-Revenue Water Management through Analysis

About Umred

Umred is a tehsil head quarter in Nagpur District at a distance of 50 Km from Nagpur. Municipal council makes the civic affairs of the town. It is a “B” Class Municipal Council. The topography of the town is undulated. The population of the town as per 2011 census is 54043.

Umred Municipal Council intends to implement 24×7 water supply scheme and provide continuous water supply to all its consumers. In addition they are focusing on implementing latest technology system and measure water consumption / Non-Revenue water to reduce techno-commercial losses.

Non-Revenue Water Reforms – a basic idea

Non-Revenue water includes physical losses, commercial losses and free authorized Non-Revenue water for which payment is not collected. It is known that, the real losses from Non-Revenue water consist of burst pipes, leaking joints, fittings, service pipes, illegal connection, inaccurate meters, billing errors.

There have been many reforms that have been designed especially for Non-Revenue water management. These missions are aimed at achieving the ultimate objective to convert intermittent supply system to continuous water supply so that water will be available 24×7 to every consumer.

Problem Statement

  • There are 2 main sources of raw water for Umred WSS. 1) Pandharabodi Tank 2) Makardhokada Dam. Inspite of these sources, some of the areas of Umred like Jogithana, some part of Itwari & Parsodi are facing low water pressure problem due to higher elevation in these areas & extra use of water in lower elevation areas.
  • Water Tariff of Rs.1200 to be paid annually in the present system.
  • Consumer meters are not installed in the council hence all the consumers are billed as Unmetered Consumer on flat rate billing basis.
  • Wastage of water is high as consumers didn’t close taps.

The global objective of installation of water meters will be to measure accurate flow from the source to ESR and consumer end contribute to the improvement of the revenue collection, financial planning and management capacity of the Municipal council.

  • To reduce extra use of water
  • Distribute Non-Revenue Water equally
  • Improve revenue collection
  • Increase the efficiency of the entire water system including Non-Revenue water
  • Prevent water shortage during dry seasons.
  • Enable the department to equitably adjust water rates.
  • Lower the operating cost of the water works.
  • Reduce the amount of Non-Revenue water pumped without depriving the consumer.

Pre-requisites for the Project

The only pre-requisite for the project was Consumer Data.

In 2012, CEINSYS has worked for reform works in Umred council. For this project we had prepared GIS map in which every consumer was linked with building feature. The same map is being used in metering project; Addition/Deletion of new consumers is being done on regular basis. With this the updated GIS Map will be ready with the council which can be further used for better decision making.

In the year 2012, a reform was carried out in Umred Council, wherein it was recommended –

  • To install the consumer meters at consumer end that will help to measure the revenue as well as Non-Revenue water consumption accurately.
  • Taps should also be either installed at consumer end or should be thoroughly checked to stop wastages of the useful water.
  • Billing should be done on monthly basis instead of annual/yearly basis. This will increase the revenue of the council and self-sustainability of the water supply system.
  • To develop a water billing software for the billing / revenue department to charge on the consumption basis from the consumers. This will add up to accountability on consumer part.

  • Consumer Meters of 15mm, 20mm, 25mm

  • Low water pressure problem in Gangapur, Jogithana, some parts of Itwari & Parsodi has been resolved after 100% meter installation as extra use of water in lower elevation areas has been reduced.
  • Discharge at ESR outlet is reduced due to which the time required to empty the ESR’s has increased.
  • Consumer list has been finalized by council after 100% meter installation which was not accurately managed before installation.
  • All the existing consumers are now linked with GIS map.

Ceinsys Tech has played a pivotal role in adequate measuring, monitoring and reporting systems of various Non-Revenue water supply schemes. CEINSYS has also developed Non-Revenue water as well as revenue from water accounting standards, standardized reporting formats, benchmarking of Non-Revenue water as well as revenue from water, accounting systems and provided with consistent metering systems. All this has made CEINSYS as the first choice for various water solutions & systems.
