Rainwater Capture


It is urgent for rainwater to start to be considered as a valid water supply for families and communities. It is possible to capture, store, purify and bottle rainwater. Rainwater that would normally flow off a roof and down the drain can be used for garden watering, outdoor washing, car washing, etc. instead of using treated tap water.


At Green Beat we provide consulting and install rainwater capture systems!!



The problem is real and it’s NOW: The scarcity of fresh water is becoming one of the most critical natural resource problems facing mankind. The 21st Century has been named the “Century of Water”. About 2 billion people currently face water scarcity, which is the main reason why 15% of the world’s population is malnourished.


3 – 4 million people die each year of illnesses caused by lack of potable water. Every 8 seconds a child dies of a disease related with non-suitable drinking water due to poor conditions of water sanitation and hygiene. Furthermore, the decrease in subterranean water reserves, water contamination and the general deterioration of water resources has led to a decrease in the diversity of living species related with water and an increase in the number of species suffering high risk of extinction around the world.


In addition, the supply of fresh water available to humanity is decreasing due to the rising contamination of water resources. In some countries, the lakes and rivers have been transformed into receptacles of an abominable variety of wastes.


There’s a solution: one of the solutions to potable water scarcity is to put rainwater to better use, since one millimeter of rainwater is equal to 1 Litre per square meter.


Components of a rainwater capture system:

  • Catchment area
  • Conduct system
  • Filtration and treatment
  • Storage infrastructure


How it works: The rainwater is captured in a catchment area, which varies in every case (may be on the roof or may be a tank fitted to the drain from the roof, etc.). The rain captured then passes through a conduct system (pipes, tubes, etc.) and a filter that removes leaves and other matter, until reaching a storage tank. Depending on the uses intended for the water more than one filter may be used. Finally, the water from the tank is dispensed, using gravity or a pump, to be reused.



  • Can save 30-50% of tap water
  • This saves you money by reducing your water bill
  • Reduces demand on groundwater and rivers by water companies
  • Responsible way of using a precious and limited resource
