Villa Park Stormwater Reuse – Roseville, MN

Lake McCarrons is an 81-acre lake in southeast Roseville, adjacent to the Villa Park Wetland system, a key subwatershed contributing to the lake’s water quality. SRF worked with Capitol Region Watershed District (CRWD) and the City of Roseville to design an innovative stormwater harvesting and reuse system to improve downstream water quality and reduce phosphorus levels flowing into Lake McCarrons.

Smart Stormwater Management with Reuse System

SRF studied the upstream watershed and identified stormwater best management practices (BMPs) that could reduce annual phosphorus loading by at least 45 pounds, a 28 percent reduction. The preferred solution included a large underground infiltration system beneath the B-Dale softball fields in Upper Villa Park.

To enhance sustainability and reuse potential, the design added a concrete underground stormwater retention tank that collects stormwater for reuse in irrigating the ball fields. This system helps reduce both nutrient loading and municipal water use.

Predictive, Adaptive Management Technology

A key innovation was integrating a predictive stormwater management system that uses real-time weather forecasts from the National Weather Service to preemptively draw down water levels in the underground tank. This allows more stormwater to be captured during upcoming rain events and increases overall treatment effectiveness.

The complete system is predicted to remove up to 53 pounds of total phosphorus annually, improving lake water quality while supporting green infrastructure.
