What is the Actual Water Consumption for Resedential Projects?
By the year 2025, half the world’s population will be living in water-stressed areas.Water Requirement in Residential Building varies based on house size and income type.The National Building Code (NBC) requirement is 135 lts/day/capita. The Breakup is as given below.
It is up to each one of us to say whether these numbers are really needed.However, a detailed indulgence has to emerge for “true water demand” to be understood and systems should be designed based on true demand.
Understanding the issue:
In an era of water scarcity and limited water supply, it is our responsibility to use the water wisely. A serious effort needs to be made to understand the true demand.
Does bathing really require 55 lts? Do you really want to flush down 30 lts of water? Are these numbers appallingly high?
Our experience has shown that high income households tend to consume 250 litres (per head and above) and sometimes as high as 600 litres. Many homes on the other hand make to do with as little as 100 litres per person per day.
There are many water conservation fixtures available in the market. These devices, such as taps or showers with flow fixtures or aerators help in minimising the use of fresh water and reduce load on wastewater systems.
These fixtures provide the same effect as conventional flow fixtures, whilst reducing the volume of water flowing through the system.
Approximately 30% of your demand can be reduced by usage of efficient fixtures.
