Pentar developed a system to irrigrate the water on the field of the Minnesota Twins. The installation of Pentair makes sure the rainwater that falls on the field and lower grandstand is recycled.

The rainwater and irrigation water on the collection area goes through an underground drainage system and travels through a  culvert, that runs under the warning track in the outfield, to a well.

The water will be filtered to a level of 0.01 micron using a hollow-fiber ultrafiltration (UF) system at a rate of approximately 125 gallons per minute. The feed and back-pulse pumps for this system are integrated into the . The UF system is back-pulsed and cleaned at a frequency based on the build up of pressure due to the accumulation of suspended solids removed by the UF system. The backwash from this filter is discharged to the sanitary sewer.


The water then goes to a holding tank and is re-circulated through another UV disinfection system to maintain water quality

Watch the video of Pentair's Executive Vice President Philip Rolchigo explaining the installation.
