24 x 7 Water Supply - it’s reality

Sauber Environmental Solutions is a Design and Engineering consulting company for 24x7 water supply system in India.Drinking water supply in India continues to be inadequate, despite long standing efforts by the various levels of government and communities at improving coverage. A number of innovative approaches to improve water supply have been tested in India, in particular in the early 2000s. These include demand-driven approaches in urban & rural water supply since 1999, , a public-private partnerships to improve the continuity of urban water supply, and the use of microcredits for water supply and sanitation in order to improve access to water and sanitation.

Throughout the world, municipal authorities have found that continuous water supply is the most efficient and cost-effective way of supplying water. This is because leaking pipes must be fixed before a 24x7 water supply system can be put in place. This, in turn, reduces the amount of water lost in distribution and makes more of it available for supply. In the long-term, these improvements reduce operating costs, unlike intermittent supply where pumping costs are high, the durability of pipes is reduced, and it is difficult for providers to ascertain how the network is operating.

Continuous water supply is critical for the people’s health. When the pipes remain full, the water remains clean. Under intermittent service, when pumping stops and the pressure in the pipes drops, groundwater from the surrounding areas can be sucked in, bringing with it wastewater from homes, and drains. If the pipes are continuously filled with, and supplying, water there is less chance of such contamination. Continuous water supply thus helps keep water clean and safe for consumers.

Services we offer:

  • Distribution network improvement on district metering area (DMA) basis for keeping Non Revenue Water ( NRW) within acceptable limits
  • Provision of individual metered connections to citizens
  • Provision of uninterrupted continuous water supply
