Quick Answer
For livestock water needs, a general rule of thumb is to provide at least 1-2 gallons per minute (GPM) per animal for drinking, with additional water needed for washing, feeding, and other purposes.
Cistern Sizing for Livestock
When sizing a cistern for livestock water needs, consider the number and type of animals, climate, and water usage patterns. A common approach is to estimate water demand based on animal type and weight. For example, a 1,000-pound cow requires approximately 12-15 gallons of water per day, while a 100-pound goat needs about 2-3 gallons per day.
Cistern Capacity and Overflow Protection
To account for variability and unexpected water demands, it’s essential to size the cistern to provide a minimum of 1-2 months of water storage, depending on the climate and water usage patterns. Additionally, ensure the cistern is equipped with an overflow valve and protection system to prevent water from spilling or contaminating the surrounding area.
Water Distribution and Storage Considerations
When planning cistern water distribution and storage, consider using a header tank or elevated storage tank to provide gravity-fed water to livestock, as well as a secondary distribution system for washing and other purposes. Use a cistern treatment system, such as sedimentation, filtration, and disinfection, to maintain water quality and prevent algae growth.
