Inflow Dishes

On a typical rainy day a manhole will allow 2,000 to 9,000 gallons of inflow to the collection system. The primary function of an Inflow Dish is to stop the inflow of rainwater into the sewage system which adds to the cost of sewage treatment and causes dramatic spikes from normal day flows resulting in possible backups. Inflow Dishes also control manhole odors, keeps silt out of the system, and helps to prevent manhole rattling and flipping due to street traffic.

The style of inflow dish shown is made from extremely durable HDPE plastic and is supplied with a vent, nylon handle, and neoprene gasket weighing only two pounds.
