Rooftop Rainwater Harvesting

Rooftop Rainwater Harvesting

History records show that there were a lot of different water harvesting methods in different civilizations, such as in India, Rome, China, and Africa. The Middle East has a lot of records for harvesting water because they mainly live in deserts and arid areas. A basic design involved placing a basin at the bottom of the water’s fall and using rocks or clay to keep it steady.

Countries have become more developed, and people have developed better water harvesting systems to prevent bacteria and the spread of diseases. Harvesting water in the modern-day includes a range of technologies that clean it out and pump it to more than one household without drying up. The following is a detailed breakdown of the rooftop rainwater harvesting system, its features, functions, and basic principles of commercial rainwater collection systems.

The Basic Functions And Features Of Water Harvesting Systems

Things That Make A Successful Water Harvesting System

  • Water harvested from the rooftop should be odorless, transparent, and tasteful.
  • The pressure should allow the water to flow to all designations at optimal speeds.
  • The storage should allow fresh water to get in to prevent odors and bacteria growth.
  • A great system will match the area of service, meaning there should be enough water throughout the day for all kinds of household activities like washing dishes, clothes, and taking showers.

The roof is the first feature of any system and is the most common because it has minimal contaminants and a large surface area to collect the maximum water. Any roof can collect water, but the most recommendable is one made of rubber, slate, or tin because it will have minimal contaminants.

Diversion To Storage

The next step is to divert the water to the storage, above or below the ground. The water passes a pre-storage vessel that filters out contaminants and keeps the water fresh with a high oxygenation level. Our filtration is effective because it has an efficient structure, and you will not need to replace it after a couple of years.

Rainwater storage can be one of the most complicated stages because we want to protect it against UV exposure, prevent the damage of the protective film that forms at the bottom of the tank, and allow excess water to flow out without compromising the water inside the tank.


Rainwater harvesting includes a pump mounted inside the tank and is robust enough to transport the water to different areas at the correct pressure. Water that passes through the tank may still go through another filtration stage to remove excess sediments and remove bacteria from flowing into your home system. The most advanced systems have indicators to show the level of water in the tank at all times and the pressure in the storage and pipes.
