Residential Water Use Calculator

How much water do I use? How do I compare? How can I conserve?

Home water conservation is easy once you understand how and where you can use less. This handy calculator takes individualized input by homeowners and shows which of their water uses are efficient and which are not. It also offers tips that save water and energy.  The calculator quickly estimates how much water homes use indoors and outdoors, then compares consumption to average and highly efficient homes in the same area with same number of residents. It also suggests where to begin water-use efficiency improvements. 


How much water do you use?

The residential water-use calculator compares your water use to a similar average and efficient house in the San Diego region.  The calculator estimates the energy savings and carbon footprint of your hot water usage, and helps identify specific areas for improving overall household water efficiency. Water conservation is easy and the water calculator gets you started right away.


The water calculator is a collaborative project of the Alliance for Water Efficiency and The Field Museum and was made possible by a grant from the Hans and Margaret Doe Charitable Trust.
