Rainwater harvesting can reduce mains water consumption by 30%. Rainwater harvesting often forms a vital component of an organisation's water strategy as it can save up to 75% on potable water bills as part of a total water management project.
Use Rainwater for:
- Flushing toilets
- Cleaning processes
- Cooling water processes (e.g. Refrigeration, cooling towers)
Waterscan provide free rainwater harvesting surveys and design suitable rainwater harvesting systems as part of a complete package including supply and installation.
Each system comprises of two components: a storage tank with integral filter and a WaterManager to deliver rainwater to the point of use.
Waterscan offer a range of WaterManager products including the RW750 & RW1000 the most sustainable rainwater harvesting systems on the market. They are compact engineered units with all mains components housed in a single enclosure cabinet:
- Easier to install with reduced labour costs
- Intelligent remote monitoring allows scrutiny of operational efficiency and water saving made
- Innovative dual pump uses 20% less energy, each pump being used alternately to extend their life
- Investment normally recouped 15% earlier that for similar units
- Built in disinfection systems improves the efficiency of the unit, enhances water quality and reduce maintenance costs
- The RW750 can supply 8-14 m3 per hour and the RW1000 14-25 m3 per hour
- When the rainwater tank is low, the WaterManager will automatically switch to mains water which is fed into the system via an EN 1717 AA air gap. Separation of the mains and rainwater ensures continuity of supply and good water quality.
Waterscan use unique steel reinforced HDPE tanks, which are custom built for each project. These offer unparalleled long term performance, excellent chemical resistance and major installation advantages. They can be installed using a granular stone bed and surround, and unlike GRP tanks do not require a full concrete surround, even when installed under areas intended for heavy vehicular usage. Because of this they have a significantly smaller carbon footprint.
All tanks are fitted with unique rotatable, integrated turrets for drainage and ducting connections, which, together with the tanks reduced weight and increased manoeuvrability, allows for a major reduction in the installation processes, time and cost. With the tanks weighing, on average, 25 times less than concrete there are also obvious health and safety advantages. In areas with high water tables pre-cast concrete slabs are available to provide instant anti-floatation protection.
