Water Usage Stastics - Reuse Design
(OP)
Hello Everyone,
I'm looking for a design resource to gauge the amount of water each person will use for: showering & toilet / day.
The facility is an addiction treatment centre.
We would like to reuse the shower water for toilet water, so for such a facility i'm looking at design value for Time showered per person per day, and number of flushes per person per day. Could anyone point me at a good resource / book for this information. Thanks so much.

Old showers use up to 5 gallons of water per minute. Water-saving shower heads produce about 2 gallons per minute.
3 gallons per day for toilet per person. Most new toilets use 1.6 gallons per flush, but many older toilets used about 4 gallons.

The average American shower uses 17.2 gallons (65.1 liters) and lasts for 8.2 minutes at average flow rate of 2.1 gallons per minute (gpm) (7.9 lpm).

Institutional facilities tend to use slightly more water.
