FP McCann, Rainwater Harvesting Chambers


FP McCann’s rain harvesting chamber is a bespoke precast water storage chamber that is compatible with water harvesting systems for residential, industrial/commercial and agricultural installations. Capturing rainwater for re-use offers significant cost savings for the user and benefits the environment by increasing water resources and further enhancing water amenity. The chamber complies with Environment Agency SuDS (Sustainable Urban Drainage System) directives.


The Rainwater Harvesting Chamber also helps ease the growing pressure on the UK’s water infrastructure by capturing water run-off thereby reducing flood risk in an already overloaded drainage network. The controlled management of rainwater run-off is key to the Environment Agency’s SUDS (Sustainable Urban Drainage Solutions) directive. Future domestic, commercial and industrial developments will be subject to planning guidelines that strongly feature SuDS initiatives. Easi-Rain is one sustainable solution in the water conservation challenge.
The Rainwater Harvesting Chamber is part of FP McCann's environmental range of waste water management products.
