Surge blocks

The Waterra Surge Block is an excellent well development tool. It simply press fits over the body of the standard or high flow footvalve (D-25 or D-32). The surge block minimizes the annular gap between the footvalve and the well casing, surging and pumping simultaneously when the pump is operated. Developing wells in this manner is one of the best methods, often resulting in turbidity levels below 10 NTUs.
