Rainwater Harvesting
Rainwater Harvesting Components from WISY provide high-quality German-engineered rainwater harvesting solutions.
These rain harvesting methods include rainwater collection, filtration and pressurised rainwater distribution for domestic, agricultural & commercial facilities.
Rainwater is collected from the roof area and passes via gutters and downpipes through a rainwater filter to remove debris & solids such as leaves.
WISY LineAr 100 Inline Rainwater Filter
The filtered water flows to the underground rainwater harvesting storage tank, from where it is pumped into the building to supply non-potable appliances such as toilet-flush cisterns, the washing-machine as well as outside taps for garden use.
WISY has made rainwater harvesting become an immanent part of modern facility water saving techniques. Experience and steady innovation over the past 20 years ensure quality and longevity of the entire WISY rainwater harvesting product range.
Domestic facilities can substitute 50 % of water use with harvested rainwater!
The average domestic house can substitute 50% of its water use with harvested rainwater, while potential savings at non-domestic facilities may be even higher.
Due to the immediate and long-term benefits, the introduction of Rainwater Harvesing Systems is gaining popularity in the domestic, commercial & industrial sector as well as in public sector buildings such as schools & universities.
As well as feeding non-potable applications such as toilet-flushing & washing-machines, harvested rainwater can also be used for irrigation & industrial cooling processes etc.
Therefore, a significant amount of daily water use does not have to meet stringent drinking water standards and can be substituted with harvested rainwater!
WISY rainwater harvesting at domestic, agricultural, commercial and industrial facilities.
Rainwater harvesting and water conservation is today an essential investment to reduce immediate and long-term facility operational costs.
A rainwater harvesting system will be in operation for several decades. Proper planning, adequate tank-sizing and the selection of suitable quality components are essential to ensure long-term economical operation of the water harvesting system.
WISY is a founder member of the German Association for Rainwater Harvesting and has also actively participated in several DIN committees which drew-up the currently applicable standards for rainwater harvesting in Germany and Europe.
Product durability and reliability are a distinctive feature of the WISY brand.
Consequently, WISY's products have been included in several thousand projects throughout the world, especially where professional rainwater harvesting solutions and water conservation are required.
A substantial amount of daily water usage does not have to meet drinking water standards and can be substituted by installing a sufficiently-sized rainwater harvesting system!
All of the listed rainwater harvesting system components are supplied with detailed installation instructions to ensure compliance with existing UK, German and EU regulations for rainwater harvesting.
