Rainwater Collection System

Rainwater Collection System

The concept of using rainwater is appealing and straightforward because all one has to do is capture, pass it through a filter, and store it for future use. The central theme around using this alternative is to save money by using a system that falls into a smaller budget.  

The advanced water harvesting system has more than a few components, and you would need a professional to complete the entire thing to keep the water as clean as possible. We want to ensure that you get an accurate idea of how the commercial rainwater collection systems work to develop an opinion that will meet your needs.

Components Of A Water Filtration System

Storage Tanks

The two main options for tanks are installing them below or above the ground. Both options are available in different sizes and capacities to match all your different needs and offer versatile benefits. The tanks that store water below the ground must be of a more rigid material because they withstand constant moisture. In contrast, the ground above should be resilient against changing temperatures and snow. Some projects can use existing catchment storage tanks in the property, as long as they adhere to the standards of our rainwater harvesting solutions.


Filters prevent debris and solid materials like insects and leaves from getting stored water. There are a couple of different filters, such as pipes, pre-tanks, or in-tank filters, which are smaller and suitable for secondary filtration.


The water from the storage does not flow directly into the house system because we have to make sure it is at the correct pressure and volume. A header tank is placed high above the ground and offers advantages because it works in conjunction with gravity.

The break tank is slightly different because it is placed at ground level and uses a pump to boost the flow and pressure of water. It is possible to combine both tanks, especially when the project needs a more flexible and custom water flow.


Pumps are tools that allow water to transfer at a better rate because they are forcing the water to flow at a specific rate. Pump controllers detect changes in the pressure and send signals to relevant components in the rainwater harvesting system to trigger an automatic adjustment.

Valves and switches are additional features that regulate the flow of water and ensure constant water flow and supply to regulate the flow according to the electrical and mechanical settings. A backwater valve prevents contamination of the rainwater by preventing the backflow.


A professional rainwater harvesting systems installer should calculate how much piping you need and install a system that complies with local regulations and your water usage needs.

All these are only a portion of all that makes up a rainwater collection system, so it is impossible to determine the perfect makeup unless you speak with a professional who can examine the volume of water you need in your residential or commercial structures.
