Farm Water Supplies
Akopọ
No crop grows and no animal thrives without water, yet rain rarely falls when and where a farm needs it. A reliable water supply, clean enough to drink and stored against the dry season, is one of the foundations of a productive farm. Get it wrong and stock go thirsty, milk yields fall and disease spreads through dirty drinking water; get it right and the farm keeps working through the driest months.
In this lesson you will learn where farm water comes from, for people, for livestock and for irrigation, and how to make it safe by settling and filtration. You will see how a storage dam is built to hold back water that pushes harder the deeper it gets, and how water is then stored in tanks and piped around the farm, down to fixing a leaking tap with a new washer.
