By making this electronic purchase, you have immediate access to a downloadable, itemized list of the components that make up the Rainwater Filtration and Sanitizing System including links to the individual products on  Additionally, if requested a shared list from can be sent to you directly, which will automatically populate your amazon shopping cart with all components of the system.  Also included in your purchase is a complete visual overview and extremely user-friendly schematic of the system. Schematic components actually resemble the component to be used instead of complex symbols and lines.


This system is designed for typical rainwater quality and collection areas that are free of hazardous toxins or materials, which can include metal or shingle roofs.  This system includes everything from the rainwater water storage barrel to the filters, sterilizers, pump, and fittings.  You are responsible for connecting the output after the last filter in the system to your filtered freshwater storage tank.  We have designed our system to be cost effective for the long term as well as robust to ensure quality water output.  The pump and UV sanitizer are selected to ensure longevity of the system as well as adequate capacity with a large factor of safety (the UV filter can handle 2x the flow rate of the system).  For a short-term system, these components can be decreased in capacity, which would decrease cost.  If any components in this system are swapped out, ensure the exact same connections are replaced or appropriate adaptors are purchased.  This system uses NPT for all threaded connections (except at the rain barrel connection that uses a standard garden hose connection) and pex connections where possible.


Individual components of this system include:


  • On-demand Self-Priming Water Pump (6.8 gal/min, 70 psi)


  • 12 GPM UV Ultraviolet Water Sterilizer (to kill any viruses)


  • Five Filters (to remove contaminants from sediment size down to and including bacteria) including one Pre-filter, one spin-down Reusable Filter, and three Main Filters (including replacement cartridges and a clear filter housing)


  • Rainwater storage barrel


  • Gutter Guards


  • Pressure Gauges (to indicate when a filter needs replacement)


  • All required fittings and connections


  • All hoses and tubing (5/8” to 3/4” hose and tubing used throughout)


Total System Cost as of July 2019 = $851.37 + $13.69 tax*

System Requirements and Maintenance:


  • Two 120V receptacles (one for the pump and one for the UV sterilizer)

  • Rainwater collection surface of any size (200 SF can provide all the water a reasonably efficient and water-conscious home needs)


  • Occasional filter cartridge replacement for the three main filters.  Time will vary based on use, but typically every 200 to 1500 gallons.  Filters can be bought in bulk for around $2 per filter, which equates to significant money savings compared to purchasing water.


  •  The UV bulb will need to be replaced approximately every year as required by the manufacturer.


  • Ensure your local regulations allow water harvesting and apply for a permit if necessary.


Tools Required:


  • Two adjustable wrenches (a pipe wrench can be useful).


  • Pex Cutter or tool to provide clean, 90 degree cut to tubing (available for around $15 at your local department store)


  • Pex Crimper (available for around $50 at your local department store)


  • Water-grade Teflon tape for threaded connections (usually white, not yellow)


Important Notes:


Note that some items in this system may be replaced with similar products if product availability or price at a given time has changed.  We will do our best to provide replacement alternatives in this case.  Do not hesitate to contact us for additional information or help. 


The pump included in this system is designed to be robust to extend its life expectancy and increase the cost effectiveness of this system over time.  Cheaper pumps may be used, but will likely require more frequent replacement.  The typical operating pressures of this system are significantly lower than the pumps rated pressure for this purpose.
