System Components


Inlet pre-filters limit the contaminants typically present on the collection area from entering the rainwater storage tank, helping to maintain optimal water conditions in the tank. We offer a variety of options to suit most design challenges.

Storage Tank

Storage tanks include calming inlets designed to minimize turbulence in the tank during rainfall events, allowing pumps to draw from a cleaner water column. Pre-installed plumbing connections are available for easy onsite installation.

Booster Pump

Select the most efficient pump package based on your design conditions and project needs. Standardized pump packages are available with submersible and flooded suction, as well as simplex or duplex configurations. Triplex and other custom pump solutions are available on request.

Rainwater Control Station

Our pre-engineered Control Stations minimize installation costs, maximize uptime, and reduce ongoing maintenance. They simplify rainwater harvesting systems by integrating all filtration, disinfection, and equipment controls. We provide a wide variety of fully documented and pre-engineered packages, or you can work with our engineering team to develop custom designs.


From actuated control valves to hydro-pneumatic pressure tanks, we offer accessory products to meet nearly any project design need.

Modular Design

We design and build our systems using a modular approach. Our experienced engineers bundle the highest quality components to build comprehensive rainwater harvesting systems.
