HOW MUCH WATER DO YOU NEED?
The following tables list estimated amounts of water needed per day for a variety of home and farm uses. Figures represent requirements for MAXIMUM consumption during hot summer weather.
AROUND THE HOME AND FARM
| Each person per day - all purposes: | 50 gal | |
| Each horse, dry cow or beef animal: | 12 gal | |
| Each milking cow: | 35 gal | |
| Each hog per day: | 4 gal | |
| Each sheep per day: | 2 gal | |
| Each 100 chickens per day: | 4 gal |
AVERAGE AMOUNT REQUIRED BY VARIOUS HOME AND YARD FIXTURES
| Each shower bath: | Up to 60 gal | |
| To fill bathtub: | 30 gal | |
| To flush toilet: | 6 gal | |
| To fill lavatory: | 2 gal | |
| To sprinkle ¼" water on 1000 sq. feet of lawn: | 160 gal | |
| Dish Washing Machine - per load: | 3 gal | |
| Clothes Washing Machine - per load: | Up to 50 gal |
DETERMINING AMOUNT OF FLOW
The amount of flow your source offers can be measured fairly accurately by allowing water to run into a bucket of known volume (a one gallon bucket) while timing the rate of fill accurately to the nearest second. It may be necessary to build a small dam in the creek or spring to make it easier to catch water to fill the bucket. Keep in mind; the rate of flow from the source may less during drier times of the year. A 1" ram needs a flow of 3 gallons per minute, while a 2" ram may require 3 to 5 gallons per minute.
DETERMINING VERTICAL FALL
Having an adequate fall for the water from the source to the ram site is a very critical requirement. One of the easiest methods for calculating fall is to use a carpenter's level fastened securely to the top of a board cut to a specified length...5 feet makes it easy to read. See diagram below:
