Water Use and Rationing Guide


The left side of your Inverness water bill shows your average daily water usage during the billing period.

·  Many people ask how their usage compares to other's of similar household size.

·  Customers also ask what their goal for water conservation should be.

Here’s a chart for gauging your household’s daily usage as compared to a standard usage benchmark. It also lets you check how you might fare should stricter conservation measures be mandated.

Number of ResidentsBenchmark for Current UsageStrict Conservation Goal
(Household Size)(Average gallons per day)(Average Gallons per Day)
156 gals.37 gals.
297 gals.65 gals.
3138 gals.92 gals.
4179 gals.119 gals.
5220 gals.147 gals.
6261 gals.174 gals.
7302 gals.201 gals.
8343 gals.229 gals.


The gallons shown are recommended maximums for the entire household (not for each resident). 

These are not rationing allocations – not yet anyway! But you can judge what may be in store if strict rationing becomes necessary. Most households can reduce usage by cutting back – or eliminating – outdoor watering. Also, run dishwashers on short cycle and only when full; take shorter showers; flush toilets less frequently; avoid running water to waste (waiting for hot water, brushing teeth, etc.).

The IPUD’s Board of Directors will make the decision on rationing and how to implement it. You can click here to read the options for rationing that have been presented to the Board. The Directors will also be deciding on how to allocate water to properties being used for short-term rentals (such as Airbnb, VRBO, HomeAway), as well as to weekender and vacation homes. You are invited to express your thoughts on these important matters by emailing to

As of this writing, soon after the Bay Area’s sizzling Memorial Day weekend, voluntary conservation is working well – and we thank you! But streamflows continue to drop and summertime is already upon us. Voluntary conservation is keeping us going at this moment but be aware that we will have to keep cutting back steadily all the way until we see some rainfall.
