Rainwater Filtration & Purification Systems

Types of Rainwater Collection and Filtration Systems

In the world of rainwater collection and filtration systems, there are three types that provide varying levels of purification. Whole-home rainwater filtration is no problem for filters that utilize all three types to provide suitable flow rates to 22 GPM. However, if you don't need a rainwater purifier system of that magnitude, there are excellent options to fit your specific needs in these three categories:

Sediment: Sediment rainwater filtration units remove particulates from the water and are typically the first line of filtration post-tank. Sediment filters are crucial when protecting equipment downstream from the tank and are required prior to UV lights.
Carbon: Carbon filtration is often used in conjunction with sediment filters to improve the clarity, odor, and taste of the water. We recommend placing the carbon filter after the sediment filter and before the UV light for a reliable and efficient rainwater filtration system.
Ultraviolet Light (UV): Disinfection is simple and fast with the power of ultraviolet light systems. RMS offers plug-and-play options for many applications, along with additional features to choose from, making this an excellent option for rainwater purification.

A well-designed rainwater purification system not only improves water quality but also promotes sustainability by reducing reliance on municipal water sources and integrating eco-friendly practices into everyday life.

Frequently Asked Questions About Rainwater Filtration Systems

A rainwater filtration system can be a significant investment. Here are answers to a few commonly asked questions to help you learn more about performance, system adaptations, and upkeep before you buy.

How effective are rainwater filtration and purification systems in producing safe drinking water?

We use a multi-stage process to ensure that collected rainwater meets or exceeds drinking-safety standards. Pre-filtration systems remove large debris and oxygenate the stored water. For potable and non-potable water applications, we incorporate advanced purification technologies such as UV disinfection, which neutralizes harmful pathogens without adding chemicals or affecting the water's taste. Be sure to check with your local health department and jurisdiction when reusing rainwater for potable purposes.

Can RMS customize these systems to fit specific residential or commercial needs?

We provide a wide range of components, including different types of storage tanks, pre-filtration options, and advanced purification methods tailored to your intended water use. Whether you need a small-scale system for residential irrigation or a large-scale solution for commercial potable water, our team designs systems to meet your specific requirements. For large commercial and industrial systems, visit RMS’ Commercial Rainwater Harvesting page for more information or contact us for assistance designing your system.

What kind of maintenance does a rainwater filtration and purification system require?

Our low-maintenance systems include self-cleaning WISY pre-filters that require inspection every 4-6 months or as needed. UV rainwater purification systems may require annual bulb replacement and cleaning of the quartz sleeve. Sediment cartridges require quarterly replacement or as needed and in addition, regular pump and filter inspections keep the entire system operating efficiently. We also offer guidance on maintenance schedules and best practices to keep your system in its best condition.
