CPM Drainage has developed a wide range of Off-Site solution catchpit and silt trap manholes so why spend days constructing an in-situ catch-pit manhole on site when one-piece chambers are available now and can be installed quickly, not days!
The reinforced watertight one-piece structures offer a better design flexibility with a vast range of cored or pre-formed holes/cut-outs for inlet/outlet holes which come complete with seals
CPM modular catchpits save money and time as they are built under factory conditions to your specification ensuring dimensional correctness as well as a very high quality finish.
