    Industrial and commercial rainwater harvesting

    RainCell™ commercial rainwater harvesting systems

    The Marsh Raincell is the simplest, most reliable and cost-effective commercial rainwater harvesting system on the market.

    With storage capacities to accommodate most roof sizes the Raincell system effectively stores and distributes clean recycled rainwater to properties allowing end-users to save on their metered water costs whilst helping architects, civil engineers and contractors conform to current environmental and legislative standards.

    Rainwater harvesting system options

    RainCell X50
    For light industrial/commercial applications where space is limited or mains water top-up has been specified.

    RainCell 75H
    Ideal for plant rooms or where a break tank system has been specified.

    Is harvesting rainwater worth it?

    Yes. As well as the practical and ecological benefits given here, it is wise to bear in mind that commercial rainwater harvesting is a complex area with no quick and easy off-the-shelf solutions. Therefore every Marsh RainCell system is tailor-made to suit individual site requirements and, in association with other water efficiency measures, maximises cost-effectiveness to ensure that system payback can be achieved as quickly as possible.

    • Save on rising water costs
      It is estimated that up to 85% of mains water delivered to commercial applications is used for toilet flushing, urinal flushing and other non-potable uses. All of this can be provided by recycled rainwater resulting in reduced bills for water supply and associated wastewater disposal.
    • Reduce your carbon footprint
      Mains water is pumped long distances and heavily treated to make it potable. Up to 85% of mains water in commercial applications does not need to be potable, thus harvesting rainwater for reuse at source has a lower carbon footprint.
    • Compliance with legislation and environmental initiatives
      Specifying a Marsh rainwater harvesting system enables conformity with current legislation and initiatives for water conservation in domestic and commercial buildings:
      • British Standard BS 8515:2009 Parts 1 & 2
        British Standard BS 8515:2009 gives guidance on the design, installation, testing and maintenance of rainwater harvesting systems for applications including laundry, WC flushing and garden irrigation.
      • The code for sustainable homes
        The Code for Sustainable Homes sets targets for reducing the consumption of potable mains water from the current average level of 150 litres per person per day, to 80 litres. Code credits are awarded on a graded scale, from 1 to 6 (6 being best of all).
      • BREEAM
        The Building Research Establishment Environmental Assessment Method (BREEAM) is recognised as the standard measure of sustainable building design. It covers environmental and sustainability issues and enables developers to prove the environmental credentials of their buildings to planners and clients.
      • Sustainable Drainage Systems (SuDS)
        Environmental policy to address the issues of both quantity and quality of water run-off from sites. Attenuation and harvesting form an integral part of schemes to counter the potential problems of increased volumes which can lead to flash floods.
