Water Systems Calculator

While there are many potential herd health and environmental benefits from utilizing a watering system, the main economic benefit is the potential increase in weight gain. The Economics of Water Systems Calculator is based on a study by Lardner et al. (2005) which analyzed the results of pumped water versus direct access over two periods, early summer (Period 1) and late summer (Period 2). Calves whose dams drank from water troughs gained an average of 0.09 lbs per day more than calves whose dams had direct access to the dugout.

Lardner’s research also found that both aerated and untreated pumped water affect yearling steer performance compared to direct access to dugout. Yearling steers gained 0.07 – 0.26 lbs per day more when drinking from water troughs, depending on the time of year and water aeration.

The Economics of Water Systems Calculator has two interfaces – one for cow-calf pairs and one for yearling grassers. Input information from your operation into the yellow cells to determine the initial cost of different water systems and the number of years to pay off the initial cost.

Peak daily water use per cow-calf pair (litres per day)
e.g. A 1300 lb cow/calf pair needs 43 - 67 litres per day. The high number is for peak demand on hot summer days above 25°C.

Estimated Initial Costs of Watering Systems

  • Prices for the well, trough, and storage tank are automatically populated from the Water System Information section.
  • If a well or storage tank is not needed in any water system, it will not appear in this section.
  • Enter the required units for the pump, pipe, well, trough, and storage tank. If any of these are not needed, enter 0 units.
  • Water system costs can vary widely based on factors such as water source type, distance, number of livestock, and topography.

Potential Additional Weight Gain - Pumped Water vs. Direct Access

  • While there are many potential herd health and environmental benefits from utilizing a watering system, the main economic benefit is the potential increase in weight gain. The following is based on research by Lardner et al. (2005), which analyzed the results of pumped water versus direct access over two periods, early summer (Period 1) and late summer (Period 2). Lardner’s research found that pumping water without treating it (via aeration or coagulation) appeared to be the most effective option for cows and calves.

Results

  • Note: The economic benefits calculated in the tool are based solely on potential additional weight gain from pumped water compared to direct water access. But producers should also consider the additional benefits related to animal health, pasture utilization, and environmental sustainability when evaluating the overall value of their water system.
