Rainwater can be harvested from a variety of roof types. Varying from shape, size, and material. Obviously, the larger the square foot of rooftop, the more water that can be collected. Generally, a footprint of 1750 sq ft or more can solely supply an entire family with water, but often even less than that is needed.

Using 100-year rainfall data, we can give accurate estimations to each home using rainwater harvesting in regards to their monthly water collection. An abnormal amount of annual rainfall is not needed to rely solely on rainwater harvesting, here in Tennessee, where we average around 50 inches annually, this is plenty of water to fully supply a home.

After falling to the rooftop, the rainwater flows through normal house gutters and into the downspouts.

Rainwater is the purest water that can naturally be found right before it reaches your rooftop. Therefore, when using the correct design and processes, rainwater can easily become very high in quality when compared to municipal water, well water, and spring water. It is naturally soft and very low in total dissolved solids. An amazing alternate water source to supply a home for all uses: drinking, washing, bathing, and the list goes on.

Normal downspouts can be used in rainwater harvesting systems as long as the storage can be placed underground or downhill and above ground storage, there are other systems that do require watertight downspouts where water can remain in the downspouts – known as a wet conveyance system.

Automated backup source function is widely available for rainwater harvesting systems with access to a secondary water source. Therefore, should the rainwater storage ever run out, the water will be kicked over to a secondary source automatically.

PerfectWater’s rainwater harvesting filtration design incorporates the whole system, starting with the roof, pre-tank storage, tank components, all the way to the actual filtration control center. We incorporate a simple filtration design alongside Ultra Violet protection to eliminate any possible bacteria so that the water remains 100% safe, pure, and tastes great.

Easily access the primary storage tank for maintenance and inspection.

From the downspouts, the rainwater enters the conveyance that transports the water to the pre-storage filter and into the storage tank. This is when coming in during new construction can be very helpful to completely maintain the landscape design by installing sleeves under driveways and walkway etc.

This component filters out the large contaminants that are 500 microns and above. Leaves and other debris that end up on roofs will be filtered out.

When rainwater fills up the storage tank, overflow can either be sent into groundwater recharge or runoff.

Sensors and tank level transmitters can be installed to reflect real-time data of the water within the tank.

There are many storage options and types. This particular system is underground storage, above ground is widely popular as well.

There are multiple tank components that are designed to work perfectly within our rainwater harvesting system process. These include: smoothing water inlet, overflow device, water skimming collection device, pump, tank level indicator, and more. These components must each be put in place to work harmoniously together.

This water from the pre-storage filter and storage overflow can either be sent to groundwater recharge or water runoff.

The pressurized water line that supplies the home with water that was collected with rainwater harvesting. High pressure and excellent flow, from source to supply.

The biofilm is naturally formed microbial layer that is at the bottom of the storage tank that helps maintain the water in storage as odor-free, slime-free, and clear.
