What is a rainwater harvester?

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

Rewatec rainwater harvesters (formerly Éconeau rainwater harvesting systems) are ideal for any roof type. They can easily be configured for winter use, giving you all-season access to abundant — and free — rainwater that contains no minerals, chemicals, or heavy metals.

Rewatec rainwater harvesters can reduce drinking water consumption by up to 70% for commercial and community applications.


Applications

  • homes and seasonal cottages
  • office buildings
  • schools
  • microbreweries and wineries
  • orchards
  • community pools
  • ice rinks
  • projects seeking LEED certification

Why harvest rainwater?

According to the United States Environmental Protection Agency, the average American uses 88 US gal of water at home every day.

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.

Uses for rainwater

Harvested rainwater can be used in countless ways. Some of the more common uses include:

  • flushing toilets and urinals
  • washing clothes
  • washing vehicles
  • watering and irrigation
  • filling pools and spas
  • flooding ice rinks
  • cleaning roads and sidewalks
  • supplying fire hydrants
  • watering livestock

How do our 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 storage tank.

Storage

Collected rainwater is stored in a leak-proof tank that is installed on the property or inside a building.

The tank is equipped with a circulation system that prevents water stagnation. During a downpour, as the tank fills, 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.

Rainwater harvester maintenance

Rewatec rainwater harvesters are designed to operate reliably and autonomously for years. But, like all rainwater recovery systems, they require periodic maintenance to ensure high performance.

As part of this simple maintenance schedule, the property owner should:

  • rinse ground filters twice per year (spring and fall)
  • rinse the toilet-supply filter (every three to six months)
  • empty aboveground tanks, open the taps, and put the pump into storage (for seasonal use)

Rainwater harvester warranty

Our rainwater harvesters come with a 10-year warranty for underground storage tanks.
