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:
|1 inch||3||2-15 feet||10-150 feet||100-2000 gallons per day|
|1.5 inch||3||2-15 feet||10-150 feet||200-3000 gallons per day|
|2 inch||3||2-15 feet||10-150 feet||200-4000 gallons per day|
The above figures may vary depending upon each installation and location of the pump site. The figures have been accomplished with actual field installations with proper setup and optimum conditions.
Horizontal distances are “almost” of no concern due to the slow volume of water being pumped. There is an amount of “Surge Friction” at the head of the pump but nominal. Distances of over 15,000 feet have been achieved with as little as 7 feet of fall, 26 feet of vertical lift with a 1-1/2″ pump delivering approximately 1,100 gal/day.
The optimum pumping ratio is generally considered as 3: 1. Meaning 3 feet of lift to every 1 foot of fall. The “maximum pumping” ratio is 10 to 1.
