Most simply, rainwater harvesting is the collection and storage of rainwater for reuse. Modern rainwater harvesting make rainwater a viable alternative water source; if contamination is minimal rainwater provides a sustainable and high quality source of water. Rainwater harvesting can be designed for both residential and commerical buildings.

Rainwater can be harvested and stored for a variety of uses in residential, commercial, and agricultural settings. It is a renewable, sustainable, high quality and free water source available to anyone. Almost pH neutral and free of additives, rainwater provides cleaner water than that obtained from groundwater sources.

Even though capturing rainwater had been accomplished as much as 4,000 years ago in India, Greece, and Palestine, rainwater harvesting technology has been continually developed since then and has adopted many of the practices used in modern water systems. Current design standards have created a foundation to ensure rainwater harvesting systems produce water of high quality that will safeguard human and public health.

Cleanflo rainwater harvesting systems proactively limit contaminants by utilizing the preventative approach to water supply. This is accomplished by limiting initial contaminants in the rain water or source water. This is compared to the current avenue to water treatment of retroactively removing contaminants from the source water (i.e. well, lake, river or pond). Using the proactive preventive approach, rainwater becomes far less expensive than other water sources because it is much easier to treat and does not need to be moved large distances. Cleanflo rainwater harvesting systems can supply 100% of your water needs for minimal ongoing costs.

A correctly designed rainwater harvesting system includes the 7 major components described below. Prefilter, Rainwater Tank, Calming Inlet, Floating Filter, Skimming Overflow, Pump, and Treatment. Cleanflo Water Technologies’ design process is suitable for residential to large commercial systems for any water applications and demand requirements.

Rainwater harvesting systems are often built with specialized rainwater harvesting parts which make the rainwater cleaner, or simplify the usage of rainwater.

How a rainwater harvesting system works

Rainwater harvesting parts - Prefilter | Rainwater Harvesting systems use a prefilter to remove particals before they enter the tank so keep the water quality as high as possible.

Filters and aerates the water prior to storage More Info

Rainwater harvesting parts - Integrated Rainwater Tank | Rainwater Harvesting systems use a specialized tank and parts to keep the water clean and safe.
Integrated Rainwater Tanks

Allows for the safe storage of rainwater More Info

Rainwater harvesting parts - Calming Inlet | Rainwater Harvesting systems use a calming inlet to prevent agitating particals settles in the tank.
Calming Inlets

Prevents agitation of sediment on bottom of the tank More Info

Rainwater harvesting parts - Floating Filter | Rainwater Harvesting systems use a floating filter to prevent pulling debris into the pump or water lines.
Floating Filters

Draws the the most oxygen-rich water into the pump More Info

Rainwater harvesting parts - Skimming Overflow | Rainwater Harvesting systems use a skimming overflow to remove floating debris from the system.
Skimming Overflows

Removes fine floating particles More Info

Rainwater harvesting parts - Pump | Rainwater Harvesting systems almost always use a pump to distribute water from the rainwater tank.
Rainwater Pumps

Utilizes a water pump to effortlessly pressurize rainwater More Info
