New drainage tech: the downpipe

Working of the capacity down pipe (1, empty; 2, filling-up; 3, over-flowing; 4; full; 5, drained)

A case study in Manchester with different solutions for water infiltration and retention systems, showed that soak-aways and infiltration trenches are generally less preferred than capacity down pipes, ponds and filter strips.

And this wateringpipe – the capacity downpipe (CDP) – works even better.

It has a very low footprint, can be integrated in water storage systems and retention. And … it is inexpensive.

Downpipe

The capacity downpipe (CDP) is a new sustainable drainage system (SuDS) invention by the company Watering Pipe. The working of the system is shown in the picture above. The system can reduce flooding by storing or redirecting roof run-off water. The overall amount can be significant considering that typically about 20% of urban areas comprise roof tops.

The Capacity Downpipe system offers many such solutions:

  • Store rainwater in a compact space
  • Continually refresh the stored water
  • Save water by managing rainwater
  • Redirect storm water by recycling it
  • Useful location for easy access to water
  • Fits to hose connections and power washer

Storm water retention

The CDP concept is about changing flooding and water demand issues. It is similar to a water butt however the difference is that using this system water, it can be integrated into applications easily:
  • on a larger building
  • the height of the container allows the water to be piped into the property
  • or around the garden

This CDP is meant for water reuse and water retention.

The CDP valve has been design into a chamber for regulating storm water flow. This has the effect of making a cities sewer system have storm water retention increased capacity.

Clean water

Depending on the actual height of the down pipe, up to approximately 120 liter of water can be stored within the capacity down pipe system. The stored water is being refreshed during a strong rainfall event. When the pipe is full, the overflow system cleans out any sediment or sludge that has built-up at the base of the container preventing water contamination.

Traditional drainage often creates flooding and pollution problems in the lower catchment. The implementation of sustainable drainage systems (SuDS) can help to achieve these goals at similar or reduced construction costs.
