What is a diversion or control valve used for in an ET system?

In an Evapotranspiration (ET) system, a diversion or control valve serves a critical purpose by facilitating the connection of multiple treatment fields. This allows for the effective management and rotating of these fields to enable adequate resting periods. By diverting the flow of effluent to different fields, the system can ensure that each field receives appropriate downtime to recover and improve treatment efficiency. This resting period is essential for maintaining the overall health of the soil and the treatment system, as it allows for the natural processes to amend and rejuvenate the soil microorganisms that play a vital role in purifying the effluent.

This functionality is essential in maximizing the efficiency of the ET system and ensuring that it operates within its design parameters while minimizing the risk of overloading any one part of the treatment area.
