  • Rainwater harvesting tanks 

The tanks that are capable of storing high-quality rainwater in large quantities are known as rainwater harvesting tanks. You can utilize these tanks for domestic, commercial, and agricultural purposes. The tanks can store around 1350 to 20,000 liters in a single unit. Plastic water tanks store rainwater efficiently and safely with higher storage capacities. 

  • Build or set up a rainwater harvesting system 

The harvesting system consists of a tank with a harvesting kit designed to collect water, filter, and pump the rainwater. Follow a step-by-step procedure to set up a suitable rainwater harvesting system. \

Rainwater filter diverter

You should set up a rainwater system where rainwater falls from the rooftop directly into the gutter. It allows the clearing of debris present in the water before storing it in a storage tank. 

Calmed inlet

The water diverted from the tank is transferred down through the pipe and to the tank bottom. Process oxygenates the water from stagnating and getting damaged. 

Overflow of siphon 

Storage tanks reach a higher capacity of overflow siphon that can easily divert the excessive remaining water to drainage. It can remove pollen from water and keep the surface water quite clean to prevent it from stagnating. 

Submersible pump 

The submersible pump transfers the water from the bottom to the tank and provides the required output to the hose, washing machine, and other appliances.
