A rainwater harvester is the best way to collect and store rain for a complete range of applications, from single dwellings to commercial projects. 

Rewatec NEO rainwater harvesters are ideal for the collection of rainwater from any roof type. Installed underground, they can easily be configured for seasonal use, giving you access to abundant and free rainwater for any application that doesn't require drinking water for use. 

 
Rewatec underground rainwater harvesters can reduce drinking water consumption by up to 50% for commercial rainwater harvesting and community rainwater harvesting applications.

 

Example applications 

  • homes 
  • gardens 
  • offices  
  • schools 
  • commercial 
  • environmental projects

How do rainwater harvesters work? 

Collection 

Rainwater is first collected by rain gutters (for sloped roofs) or a drain (for flat roofs). It then reaches a primary filter that prevents leaves, insects, and other debris from entering the system. Water that passes through the filter flows into a recovery tank. 
 
Storage

Collected rainwater is stored in a leak-proof tank that is installed below ground on the property. 

The rainwater tank is equipped with a circulation system that prevents water stagnation. During a downpour, this system evacuates liquid at the bottom of the tank to ensure that only the freshest water remains. 

 
Rainwater use 

Using harvested rainwater is simple. A specially designed pump directs stored water through a micro-filter that removes any small particles, then provides optimal pressure to supply appliances, plumbing fixtures, and building systems. 

If no rainwater is available in the storage tank, all appliances are automatically and reliably supplied from the regular water system 

 

What is the need for rainwater harvesting?

The average person in the UK uses approximately 142 L of water daily. This water is treated and distributed by costly municipal systems, and yet only a small fraction of it is used for functions that actually require potable water. 

The scale of waste is enormous - and so is the opportunity it gives us to protect precious drinking water supplies by making better use of rain.
