These user-centered solutions are built with a smaller footprint and focus on the most essential functions in a streamlined design.

Pump & Treatment Systems
Progressive Pump & Treatment complete COTS systems integrate pumping, filtration, treatment, and controls into a powder-coated frame. Backed by full drawings and documentation, they are built for performance and fast delivery without compromising quality.

Fiberglass Modular Storage Tanks
Our RainFlo FRP (Fiber Reinforced Plastic) water tanks are high quality, maintenance-free storage solutions. These environmental friendly tanks are structurally strong and watertight for years of dependability. RainFlo FRP water storage tanks utilize a hot press molding production process to ensure zero defects and constant fiberglass distribution for reliability and performance.

ProGen Max Ozone
Progressive Pump & Treatment ProGen Max OZ 30K generates up to 30 grams of ozone per hour to improve water quality in storage tanks. Includes venturi side stream injection for precise dosing and maximum output.

NFPA & NSF Storage Tanks
Our tanks are designed to meet National Fire Protection standards (NFPA-22) and NSF/ANSI.STD 61 for the potable water storage option. Our engineering team can provide certified tank and foundation design to meet specific applications and project requirements. The modular design of our water tank enables it to be packaged flat and allows for easy transportation to even difficult or remote areas.

Above Ground Water Storage Tanks
Above ground water storage tanks are widely used for the collection and storage of rainwater in addition to the storage of well water, air conditioning condensate, cooling tower make-up, fire protection reserves and manufacturing process water systems.

Underground Cistern Storage Tanks
Underground cisterns are widely used for the collection and storage of rainwater in addition to the storage of well water, air conditioning condensate, cooling tower make-up, fire protection reserves and manufacturing process water systems.

UV Disinfection Systems
The RainFlo complete UV disinfection systems feature superior performance, utilizing sediment filtration and UV disinfection to clean and disinfect rainwater for indoor potable* plumbing and/or non-potable irrigation applications.

Fiberglass Storage Tanks
The RainFlo model RF-FRP-50K is a professional, comprehensive in-ground Fibrglass Storage Tank available in custom capacities and sizes.

Maximum Yield Filtration
The Optimax-PRO XXL is a high-efficiency external water filter purpose-built for commercial and industrial rainwater harvesting systems. Designed to deliver over 95% water yield, this advanced filtration unit integrates seamlessly with large-scale collection systems while providing the durability and low-maintenance operation today’s facilities depend on.

RSC Max System Controller
RainFlo RSC Max system controller with 7" HMI touchscreen provides all in one monitoring, automation, and control of rainwater harvesting and water reuse systems. In addition to all of the features of the RSC Mid, the Max also includes additional features like ORP monitoring, recirculation functions, multi-filter control, and ozone power.

Flow Inducer Kits
these pump stations fill the performance gap between traditional standalone pumps and more expensive high-end pump stations perfectly. These mid-range automatic pump systems are for use in large residential, commercial, and light-industrial underground rainwater collection systems.
