A combined sewer/enclosure overflow (CSO) sensor system is described for accurate detection and measurement of overflow events. From the combined data, trending information can determine if there is debris accumulation. Rain masks can be used in the trending data to measure overall health. External sensors in combination with the CSO sensors provide predictive information and additional levels of information/data accuracy. The sensor system automatically and remotely monitors CSO locations and provides real-time data regarding start times, stop times, duration, and flow volumes of overflows that occur in these structures and provide regulatory and public notification of these events.

Utilizing debris basins for stormwater retention.

The invention provides for a secondary overflow pipe and connector (10) connectable to a sewer system, the secondary overflow pipe increasing overall capacity of the sewer system during peak flows, the connector (10) connectable to a manhole (16) and shaped to define a funnel to reduce turbulence and facilitate a smooth flow pattern and maximum flow capacity.

A flow splitter including a first plate being immobile and a second plate being turnable with respect to the first plate. The first plate includes a central part, and the central part includes a slot and two side parts disposed at two ends of the slot, respectively. The second plate includes a first subplate and a second subplate, and the first subplate includes one end provided with a flange. The second plate is coupled to the first plate. The first subplate and the second subplate are disposed at two side of the slot; two sides of the second plate include two gaps. respectively. The two side parts of the first plate are disposed in the two yaps, respectively.
