Get started on your public water system or other water storage needs with the exerts at Acer Water Tanks. A living unit equivalent (LUE) is defined as the typical flow that would be produced by a single family residence (SFR) located in a typical subdivision. For water, this includes consumptive uses, such as lawn watering and evaporative coolers. The sewer system does not receive all of these flows, so the flows expected differ between water and sewer. The number of LUE’s for a project are constant; only the water and sewer flows are different.


These are only estimates for planning purposes. Each building or development is evaluated separately by fixture unit count to size the meters.

These LUE calculations can be used to estimate flows for various development types. These are only estimates for planning purposes. Each building or development is evaluated separately by fixture unit count to size the meters.

One LUE produces:     1.5 GPM (Peak Hour) of water flow
                                         0.556 GPM (Peak Day) of water flow
                                         400 GPD (0.278 GPM) Average dry weather demand for water
                                         210 GPD average dry weather flow for sewer
