Demand Side Management

What ?

With booming economies, people’s expenditure patterns are changing and so do their lifestyles. Rapid urbanization is also adding fuel to these changes. As a result, food consumption patterns are changing—changes a traditional country like India would not have imagined a few decades ago.

the rapid economic and demographic changes, the food and water demand projections of India and China need regular updating.Today, India has an unprecedented economic growth (there has been an annual economic, This kind of growth has rapidly changed, certain food and water demand drivers that are endogenous to India, such as food consumption and land use patterns, and that are exogenous to India, such as world food trade. Therefore, in this context, many of the past food and water demand projections need to be reassessed. This paper revisits India’s water future assessment from 2025 – 2050.


The major objectives of this paper are to:
  • Assess the current status of food and water supply and demand in Indian river basins.
  • Project the water future of India and assess the implications of the water demand
    projections on river basins.
  • Assess the sensitivity of food and water demand projections to changes in the key
    demand drivers.


Why ?


Domestic Water Demand :

With increasing household income and increasing contributions from the service and industrial sectors, the water demand in the domestic and industrial sectors could increase substantially.We assume that the average domestic water demand would increase from 85 liters per capita per day (lpcd) in 2000, to 125 and 170 lpcd by 2025 and 2050, respectively.

The BAU scenario approach differs from the approach adopted by the NCIWRD commission. They assumed norms where the rural domestic water demand in 2025 and 2050 are assessed at 70 and 150 lpcd, respectively, and the urban water demand at 200 and 220 lpcd, for 2025 and 2050 respectively. They also assumed 100 % coverage of domestic water supply for both the rural and the urban sectors. At this rate, the average per capita water demand in 2025 and 2050 is estimated to be 126 and 191 lpcd, respectively.

Industrial Water Demand :

In a rapidly booming economy, we expect the contribution of the industrial sector to increase very much, and the industrial water demand to also increase accordingly. However, the dearth of information—the types of industries, their growth, water use and the extent of recycling— is a constraint for future projections in the context of increasing economic growth.


How ?


Demand optimization & Water saving for various usages is a prime requirement of green buildings & industries .

With the use of Water Tech (Electronics / IOT based) products & systems- demand side management could be done for Cooling towers/Flushing/ Horticulture  / Domestic applications /Ind. application etc.
