Lowertown Ballpark - CHS Field
St. Paul, Minnesota


Located in St. Paul, Minnesota, the Lowertown Ballpark - CHS Field reduces potable water use by collecting rainwater and stormwater. 33,770 square feet of roof is used to capture the rainwater with the use of vortex filters. The rainwater is then conveyed to a 27,000 gallon cistern and is reused for irrgation and toilet flushing. An estimated 450,000 gallons of potable water is saved with this system annually.



TD Ameritrade Headquarters
Omaha, Nebraska

We supplied the TD Ameritrade Headquarters with a rainwater harvesting system consisting of a 30,000 gallon rainwater storage tank and the RMS Day Tank System which provides rainwater to the toilets and urinals throughout the entire facility. Two WISY Vortex Filters are installed prior to the storage tank to remove particulate larger than 380 microns from almost 60,000 square feet of roof area.

Scheels Eden Prairie Center
Eden Prairie, Minnesota


The rainwater harvesting system for the Eden Prairie Center was designed according to ARCSA/ASPE/ANSI Standard 63. Rainwater is collected from 130,680-square foot rooftop and stored in four below ground storage tanks with a combined capacity of 52,000 gallons. The collected water is reused for toilet flushing and irrigation. It is estimated to save 405,840 gallons per year for toilet flushing alone and up to 1.2 million gallons per year in irrigation demand.  

SerVaas Laboratories, Inc.
Indianapolis, Indiana


The rainwater harvesting system for SerVaas laboraties uses a total of three WFF300 Vortex Filters. The water is used as process water for creating cleaners. Rainwater represents approximately 43% of the water used and has saved 1,552,200 gallons of municipal water in the sytem's lifetime thus far.

SRMKCCA Google Office Building
Kirkland, Washington


SRMKCCA Google Office Building collects rainwater from the roofs using two WFF300 Vortex Filters to ensure high-quality water in the cisterns. The water is then filtered down to 5 microns before entering an ultraviolet light for disinfection. The water is reused inside the buildings for toilet and urinal flushing.

Elevate at Southwest Station Apartments
Eden Prairie, Minnesota


Elevate Apartments collect rainwater using a WFF300 prefilter to ensure a high-quality of water is initially obtained. The water is conveyed to two 2,500 gallon tanks located in the basement. The water is filtered and reused for surrounding irrigation.

Seagate Media Research Center
Fremont, California

Seagate decided to integrate a rainwater harvesting system at its Media Research Center in Fremont, California to reduce demand on the municipal water supply and the impacts of stormwater runoff. To make this possible, we retrofitted their existing plumbing to accommodate a rainwater harvesting system. The facility has more than 62,000 square feet of roof area from which rainwater can be collected. The collected rainwater is used to supply non potable uses such as toilet and urinal flushing, scrubber makeup, and cooling tower makeup. The rainwater collected from the roof is pre-filtered by two WISY WFF300 vortex filters and then flows into one of two 29,700-gallon storage tanks.Click here for the Case Study published in the American Society of Plumbing Engineers (ASPE) journal.

The Bullitt Center
Seattle, Washington

Metropolitan Atlanta Rapid Transit Authority (MARTA) Atlanta, Georgia

We helped MARTA become better environmental stewards by implementing a rainwater harvesting system that effectively reduces the impacts of stormwater runoff onsite and provides irrigation for the grounds without using potable water. The rainwater is harvested from train stations to supply water for irrigation plant material onsite and utilizes our WISY WFF150 filters and is stored in 3,100 gallon tanks.

Byhalia, Mississippi

The Nike Distribution Facility located in Byhalia, MS set out to reduce the environmental impact of their distribution facility by collecting and reusing rainwater runoff. Rainwater Management Solutions was selected to help turn their goal of collecting and reusing the water runoff from the facility into a reality. After further analysis, Nike was able to reuse the collected water runoff for toilet fixtures accounting for up to 500 gallons per day of water demand. The water runoff is diverted into a larger vortex filter to separate debris greater than 380 microns from entering the collection tank. The water is stored in a 4,200 gallon underground HDPE tank from Advanced Drainage Systems (ADS). The water is then pumped up through the RMS packaged filtration and purification system so that it is ready for reuse at the toilet fixtures.

UA Local 130
Chicago, Illinois

The Local 130 Plumber's Union wanted to provide an exceptional training facility while showcasing water conservation. RMS was selected to provide a graywater reuse system alongside a rainwater reclamation system.
