About Household Water Usage Estimator
Where it goes
Typical US: showers 20%, toilets 24%, laundry 17%, sinks 15%, leaks 12%, dishwasher 1%, other 11%. Outdoor (irrigation) often equals indoor in drier regions.
Easy wins
Replace 3.5 gpm shower with 1.5 gpm low-flow: cuts shower water 60%. Fix toilet leaks: silent flapper leak can waste 200 gal/day. Drip irrigation cuts outdoor use 30-50%.
Drought tiers
In arid regions during drought (CA, AZ), tiered pricing kicks in fast. First 5 ccf might be $3/ccf; over 30 ccf jumps to $15/ccf. Conservation saves big money.
