Maintenance: Water systems serving livestock can be designed to survive the abuse and daily wear animals impose. The obvious damage to tanks and controls can be corrected. Problems that develop over time such as water intakes becoming plugged with algae, tadpoles and debris, cracked supply lines or corroded pipes creep up slowly and diminish water flow over time. Not until a hot July day do we realize a problem might exist. A few preventative maintenance measures can eliminate many of these situations.
