Regulators

Regulators are commonly used to divert a portion of sewage flow in a combined or storm water in order to prevent to overcharging of the sewer or to regulate the rate of flow to sewage treatment works. Regulators in combined sewers are sometimes designed to divert all flows greater than three to five times the dry weather flow in order to avoid the discharge of too strong a sewage into the overflow or relief sewer. The overflows from intercepting sewers should not be permitted at the points where they will adversely affect the watercourse. Types of automatic regulators include moving part devices and regulators without moving parts such as the leaping weirs and the overflow weirs.
