This article outlines typical daily residential water usage in gallons for people, appliances, and activities. This permits estimation of wastewater volume (for septic tank size determination) as well as water and well flow requirements and assists in water pump capacity or sizing specificatsions. Flow rates for common household plumbing fixtures and appliances is given as well as estimates of peak demand water usage rates for residential buildings.
This data is also useful when evaluating adequacy of private well and water supply quantity, well flow rate, and wastewater loads on onsite residential septic systems. Daily wastewater volume to be treated and disposed-of at a site determines the design parameters for onsite wastewater treatment or septic systems as well as suggesting choices among alternative septic designs and septic products.

How much water does a family use each day? What is the water flow rate for common household fixtures and appliances? How is this data used?
The following table lists water usage requirements and typical fixture flow rates or device flow rates for home and outdoor living in the U.S.
Notes to Table:
*Reverse Osmosis Systems - impact on septic systems and water use
What about water volume from reverse osmosis water treatment systems? These can vary by manufacturer with a range of 3:1 to 10:1 of waste to product efficiency. "Typically" for every gallon produced with a topo of the line system, 3 to 5 gallons goes into the septic tank. Less efficient systems (regardless of shutoffs) can dump up to 10 gallons to waste for every gallon that goes into the storage tank. See REVERSE OSMOSIS CONCENTRATE WASTE DISPOSAL for further details. -- Larry Newcomb Encinitas Learning Center
We also discuss the effects of increased water usage when buildings use reverse osmosis (RO) for water purification. This article is part of our series: Inspecting, Testing, & Maintaining Residential Septic Systems. Also see The Septic Information Website
