Rancher Concerns

With cattle prices fluctuating frequently and being difficult to forecast, the cost of getting water to the cattle has become one of a rancher’s main monetary concerns. Every dollar wasted on an inefficient watering system is a dollar of profit out of the rancher’s pocket. When faced with a need for a new watering system or to repair an old one, the natural thought is to look at the option with the lowest initial cost, but this does not always translate to being the most cost-effective option in the long run.

A wise rancher will not only look at the initial price but also consider the long-term costs along with the reliability of the pumping system. Efficient watering systems can help boost the rancher’s profits in subsequent years, and often a solar pumping system will pay for itself in the first 2-3 years of use.
