397764 - Irrigate, Infiltrate, Automate: Stormwater Reuse at Upper Villa Park

Wednesday, June 6
8:30 AM - 10:00 AM
Location: Mirage Room

Capitol Region Watershed District (CRWD) and the City of Roseville, through two State grants, constructed a 60,000 cubic foot underground stormwater infiltration system combined with a 13,000 cubic foot modular concrete cistern to harvest and use stormwater for irrigation of a high-use softball field at Upper Villa Park in Roseville, MN. The project protects Lake McCarrons, a high quality recreational lake within the urban core of the Twin Cities, and the Villa Park Wetland System by capturing stormwater runoff and filtering the pollutants associated with urban stormwater.

In addition to removing approximately 45 pounds of TP annually, the system will save up to 1.3 million gallons of drinking water by capturing and using rainwater to irrigate the softball field. The system uses real time technology to actively manage the water level in the cistern. Prior to a rain storm, software programmed to communicate with weather forecasts and level sensors within the rainwater cistern open an automated valve to drain the cistern into the underground infiltration pipes and capture more stormwater. The valve closes after the storm and fills the cistern to provide irrigation for the softball field.

To determine effectiveness of infiltration practice pollutant removal, three pan-lysimeter wells were installed at depths of 3, 5, and 7 feet below the perforated pipes. Samples will be extracted from the wells and tested to determine the fate of pollutants once they leave the infiltration system

Construction was substantially complete April, 2016. A full season of monitoring data will be obtained for presentation.
