The invention relates to a
sump well for a vacuum drainage
system. The
sump well comprises a collection well, a
sewage pumping
pipe, a drainage
pipe, a vacuum valve, a controller for controlling connection and disconnection of the vacuum valve and a
water level sensor for collecting
water level information, wherein the outlet of the drainage
pipe is connected into a vacuum pipeline, and the inletof the drainage pipe is connected with the outlet of the
sewage pumping pipe through the vacuum valve; the inlet of the
sewage pumping pipe extends into a sewage pumping level in the collection well;and a
signal output end of the
water level sensor is connected with a
signal input end of the controller. Along with sewage collection in the well, the
sump well drains automatically and intermittently to the vacuum drainage
system, has a simple structure, and does not require a lift pump, so that the problems of being low in safety, easy in blockage, difficult in cleaning, high in
power consumption and the like caused by assembling the lift pumps on multiple points can be avoided, and sewage collected by
gravity flow can be lifted to the vacuum drainage
system without extra additional power,and the sump well is convenient to check and maintain.
