Water treatment, Supply management and Non-revenue Water

Throughout the developing world, the provision of water supply is marred by inefficiencies: low coverage, high non-revenue water (NRW) levels, intermittent supply, and poor water quality.

Water Treatment and Supply Management

The basic purpose of water treatment is to produce water that is safe for human consumption and appealing to the consumer, using facilities which can be constructed and operated at a reasonable cost. The primary goal in the design of WTP is the production of biologically and chemically safe water. Another important consideration is that the water utility operations should be set up in such a way that the water quality is not impaired during transmission, storage and distribution to the consumer. From the design and operation of the treatment plant to the distribution system, the control point for water quality should be the customer’s tap. Water quality control and assessment should always be seen in the wider context of the management of water resources and treatment, encompassing both the quality and quantity aspects.

Non Revenue Water

NRW is the difference between the volume of water put into the distribution system and the amount of water actually billed to customers.

There are three components of NRW

  • Unbilled authorized consumption – Free distributed water
  • Apparent losses – Unauthorized consumption and metering inaccuracies
  • Real losses – Losses at mains, service reservoirs, and service connections up to the point
    of metering

High levels of NRW are detrimental to the financial viability of water utilities and the quality of water itself. Reducing NRW to an economically optimal level is fundamental to improving the urban drinking water supply, and for effectively responding to rapid urbanization and growing concerns of water security.

Tatva’s Water Treatment, Supply & Distribution Projects

Some of the projects that Tatva has undertaken in relation with water treatment, supply and distribution are:

  • 324 MLD water treatment plant (WTP) at Ambernath
  • 150 MLD WTP at Pen
  • 4 MLD non-conventional WTP at Chakan
  • 3.6 MLD non-conventional WTP at Ashti
  • 2800 m3 elevated service reservoir at Sector 29, Navi Mumbai
  • 2600 m3 elevated service reservoir at Warje, Pune
  • Weir at Alandi across river Indrayani for PWD Pune
  • 900 mm dia. M.S. pipeline from Century Enka to Bhosari for MIDC
  • AC Pressure Pipeline varying from 80 to 350 mm dia. 72 Kms. in length for Buldhana RRWSS
  • PVC Pipeline 63mm to 140mm Dia. 68 Kms. at Pune
  • Regional Rural Water Supply Scheme for 22 villages in BULDHANA district for MJP under World Bank Aid
  • Regional Rural Water Supply Scheme for Mangrulpir, Dist. Washim

In order to ensure timely provision of water to all sources, water supply management processes have been implemented by Tatva at the aforementioned plants. Water supply is an issue that continues to grow in importance. As water is essential to life, at Tatva we believe in ensuring that distribution of all treated water is carried out efficiently.
