The fiberglass reinforced plastic (FRP) water tanks are designed with the highest level of opacity ensuring no light transmittance into the tank, thus preventing chlorine evaporation, bacterial and algae growth. Modular FRP panels are combined to create tanks that offer accurate dimensional stability for reliability and performance.
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.
High quality GRAF Carat S underground rainwater harvesting tanks have been tested and certified by IAPMO R&T (International Association of Plumbing & Mechanical Officials Research and Testing) to Standard Z1002 as determined by Los Angeles Research Report (LARR) 5755.
The Carat S lineup consists of four modular tank units ranging from 700 gallons to 1700 gallons which are expandable up to thousands of gallons. The precision, modular, and ultra-high strength design of the Carat S makes it the choice of professionals worldwide.

UV Disinfection Systems
We offer several RainFlo ultraviolet disinfection systems for water treatment. RainFlo UV systems continuously monitor performance and display the output, diagnostics, system status, and water quality.
The RainFlo complete UV disinfection systems use sediment filtration and UV disinfection to clean and disinfect water. Our complete systems continuously monitor performance and display the output, diagnostics, system status, and water quality.
PPT Disinfection Systems
Our Progressive Pump & Treatment systems are custom made, commercial grade disinfection, reclamation, and recirculation systems. These systems utilize UV and ozone treatment technologies to destroy bacteria, spores, and microbes, ensuring water is safe for reuse.
UVS Disinfection Systems
The RainFlo UVS complete systems are ideal for reclaimed water applications. Each system includes a pump, VFD, sediment filtration, UV disinfection, and system controls to deliver disinfected water at a constant pressure and variable flow rate for use in irrigation, flushing toilets, cooling towers and other uses.
Greywater Systems
Pre-Filtration
Pre-filtration is the filtration that takes place prior to water entering the tank. These are typically gravity fed filter systems. Pre-filtration is typically the only filtration required when using the collected rainwater for irrigation.
Post-Filtration
Post-filtration is the filtration that takes place after the collected rainwater has left the tank. Post-filtration systems are typically a pressurized system that filters to a much lower number of microns than typical pre-filters. Post sediment filtration and disinfection is usually required anytime the water will be used for indoor use such as flushing toilets, washing clothes, or shower usage.
RainFlo Tank Level Monitors
RainFlo tank level monitors display the true level of liquid inside water and chemical tanks. The monitors are designed for installation on all above ground storage tanks with vertical sides. Our tank level monitors are easy to install with the float ball and counterweight in the tank and indicator outside the tank
Above Ground Pumps
RainFlo water pumps are high performance multi-stage centrifugal surface pumps for residential, commercial, and light-industrial systems. RainFlo above ground pumps are specially designed for the unique requirements of rainwater collection systems while offering exceptional performance as standard booster pumps. MHPA pumps include a pump and controller for on demand usage at a constant pressure.
Industrial Pumps
RainFlo high performance mid-range automatic pump stations for large residential, commercial, and light-industrial rainwater collection systems.
Submersible Pumps
RainFlo universal pumps are specially designed for the unique requirements of rainwater collection systems. Equipped with a large threaded bottom inlet for internal flow-based cooling and connection to a floating filter, these pumps can be installed vertically or horizontally and they can either be submersed inside a tank or mounted externally on the
ground or other platform.

Tanks - Bolted Steel
RainFlo steel water storage tanks feature the latest technology and materials utilizing a bolted steel outer shell with a heavy-duty liner. RainFlo corrugated steel tanks are configured with a variety of options including fill and overflow flanges, lids and hatches, ladders and stairs, anchors and more. These tanks can be assembled at the project site by trained installation professionals or sold as product only.
Glass fused steel water tanks are comprised of enamel frit and raw steel fused together to achieve the best cohesion blending of the strength and flexibility of steel combined with the corrosion resistance of glass. Applied to both interior and exterior surfaces, glass-fused-to-steel is low maintenance and withstands harsh environments. Our glass fused steel tanks are designed to exceed AWWA D103- 09 standards and meet NFPA 22 standards for private fire protection.
Tanks - FRP
The fiberglass reinforced plastic (FRP) water tanks are designed with the highest level of opacity ensuring no light transmittance into the tank, thus preventing chlorine evaporation, bacterial and algae growth. Modular FRP panels are combined to create tanks that offer accurate dimensional stability for reliability and performance.
RainFlo single wall, underground, fiberglass reinforced plastic (FRP) storage tanks set the standard for custom designed and made-to-order storage tank solutions for the rainwater, stormwater, fire suppression, potable water storage, and water reuse industries. Each tank is designed and fabricated to meet specific project needs by our team of water storage solution professionals. Our factory designed and engineered tank anchoring systems ensure RainFlo FRP tanks can be buried in any environment, including high water table applications.
Tanks - Plastic
Groundwater stable cisterns are capable of being buried in areas where the groundwater table may rise above the tank burial depth. In most cases, these tanks can be submerged up to the top of the tank. These tanks are manufactured using ultra-high strength materials and designs which can withstand higher than normal burial pressures.
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.
