A sewer regulator is equipped with a Cipolletti weir (U.S.B.R. standard trapezoidal weir) to control combined sewer overflow (figure below). The design criteria for the regulator is to accommodate a peak combined sewer overflow flow rate to the outfall of up to 0.85 m³/sec. If the weir crest is 2m from the invert of the regulator, what is the weir length if the regulator is designed to prevent flooding of a nearby basement with a floor that is 2.35 m above the regulator invert?

Drainage of Pavements

Pavement Drainage holds ample significance, as it prevents the accumulation of water or any liquid on the surface of pavements and ensures proper drainage system. With proper design and gradual slopes provided, the water gets easily removed from the surface into the drains, which are essential during heavy rains and unusual weather conditions keeping it less prone to accidents and increasing the durability of the pavement structure.

A sewer regulator is equipped with a Cipolletti weir (U.S.B.R. standard trapezoidal weir)
to control combined sewer overflow (figure below). The design criteria for the
regulator is to accommodate a peak combined sewer overflow flow rate to the outfall of
up to 0.85 m³/sec. If the weir crest is 2m from the invert of the regulator, what is the
weir length if the regulator is designed to prevent flooding of a nearby basement with a
floor that is 2.35 m above the regulator invert?
