During drafting operations, what is the main purpose of maintaining strainer elevation above the pond bottom?

Maintaining the strainer elevation above the pond bottom is primarily aimed at avoiding debris intake. When the strainer is positioned too low, it can easily draw in sand, silt, and other particulate matter that can clog the strainer or damage the pump. This is particularly important in drafting operations where water is being sourced from natural bodies like ponds, lakes, or rivers. Keeping the strainer elevated ensures that only clean water is drawn into the suction line, contributing to effective pump operation and minimizing the risk of contaminated or obstructed flow.

While enhancing water flow, reducing pressure fluctuations, and meeting safety regulations are also important considerations in drafting operations, the primary focus of strainer elevation is to prevent the intake of debris, which can severely impact the efficiency and longevity of the pumping system. By ensuring the strainer remains clear of the punctuated bottom sediment, operators can maintain optimal performance and safeguard equipment from potential issues caused by debris.
