A correctly designed water supply system is defined as one that delivers the required amount of water all of the time. Therefore the first step in designing a private water supply system is to determine the quantity of water needed.
The daily average water demand may be found by summing the appropriate amounts from the table of approximate daily water needs that may be viewed below.
