Milwaukee Journal Sentinel: Some Milwaukee residents to get free state-of-the-art garden boxes to help prevent combined sewer overflows

stormGUARDen in Milwaukee Homeowener Backyard

Milwaukee homeowner Aaron Pierce says he can no longer be blamed for contributing to overflows of combined sanitary and storm sewers in the city.

Pierce took the step of disconnecting the roof downspout on his N. Pierce St. home from a pipe draining to the combined sewer in the street and preventing hundreds of gallons of clear water from entering the sewer during a storm.

That was no small accomplishment on his 30-foot-wide lot on the north side since there isn't enough lawn to absorb all of the water coming off the roof. The city prohibits water from a property owner's downspout from flooding a neighbor's yard or causing ice to form on a sidewalk, street or alley.

Rainwater running off Pierce's roof is diverted to a 10-foot-long StormGUARDen, a specially designed box filled with tubs of soil and topped with flowers and native grasses that can collect all the water from storms dropping up to 3 inches of rain. The drain pipe to the combined sewer is capped.

Pierce has watched the state-of-the-art container garden fill in a storm to ensure it worked as advertised, he said.

"The really cool part of it," said Pierce, "is the overflow drain at the low end of the box positioned more than 10 feet from the home's foundation. This feature allows him to integrate the StormGUARDen into the remainder of his backyard landscape," he said.

Listen As the SSE Staff Discusses Regenerative Stormwater Conveyance (RSC) System for the North Point Lighthouse Ravine

North Point Lighthouse Ravine

North Point Lighthouse Friends spent years raising money to transform the 1888 station in Milwaukee's Lake Park from a decaying structure to gleaming public space.

“The keeper's quarters, it was in pretty bad shape, there was nothing to preserve in the inside. We took out the non-load bearing partitions and made exhibit space for what you’ve seen inside,” group president John Scripp says. Scripp says the undertaking cost $1.6 million, and after 10 tough years of work inside, the volunteers hadn’t mustered the energy or money to tend to the eroded ravine outside or its crumbling pedestrian trail.

The friends group knew storm water was a problem and installed a small rain garden. "One thing we didn't do was to put pavement on the driveway and our small parking area. Early on we wanted to finish it with some pavement that would be appropriate and thought of pervious pavement. But we didn't succeed in getting that done," Scripp says.

The volunteers' vision of what they could achieve expanded when they met civil engineer Carrie Bristoll-Groll. She owns Stormwater Solutions Engineering and was eager to test out a new stormwater management tool.

Listen to Carrie's on WUWM's Project Milwaukee Innovation Forum

Portrait of Carrie in WUWM Project Milwaukee Forum

Cultivating talent and collaboration quickly surfaced as central themes of WUWM's Project Milwaukee panel discussion on innovation and the economy. Insiders shared ideas for how Milwaukee can become and remain competitive in innovative fields.

"There's definitely so much more power in all of our numbers together," says Carrie Bristoll-Groll, a civil engineer and founder of Stormwater Solutions Engineering. It develops systems to manage storm water and control flooding. Bristoll-Groll says the firm looks for innovative techniques. So it made sense to locate in the Global Water Center in Milwaukee. It houses water-related businesses and research firms.

SSE is first in Midwest to introduce
Regenerative Stormwater Conveyance!

Regenerative stormwater conveyance (RSC) is a series of step-pools atop a porous sand media bed. RSCs are able to function similarly to stable headwater streams, effectively conveying large flows, managing storm volumes, as well as treating many typical stormwater pollutants from impervious areas. Runoff entering the RSC will immediately slow in the pools, allowing for infiltration into the media bed and essential treatment processes to occur. Most of the runoff will leave the RSC as exfiltration into groundwater, filtered subsurface seep, or via evapotranspiration. A small fraction, usually between 1% and 15% annually, will leave as non-erosive surface flow. RSCs are an effective stormwater best management practice (BMP) in the Eastern United States, particularly in sensitive coastal watersheds. However, there is no known RSC currently built in the Midwest. Stormwater Solutions Engineering, LLC (SSE) is the only firm in the Midwest to offer RSC.

RSCs were originally used as retrofits for failing channels, swales, and at pipe outfalls. As they have become more prolific, their design has been adapted to include a wide variety of applications. For example, RSC can be used at different points within the BMP treatment train. An RSC located at the front end of the train will provide water treatment, peak flow mitigation, and reduce downstream BMP retention needs. An RSC located at the tail end of the train will provide safe, non-erosive discharge of treated runoff to receiving waters. RSCs are also able to provide water quality and conveyance for sites with 0- 5% slopes. They can provide safe conveyance in slopes up to 50%. RSCs are also adaptable to space constraints. They can be installed in the footprint of roadway medians and ditches to provide conveyance and treatment needs. Or the storage potential of RSCs can be optimized when more width is available. RSCs also provide many opportunities for enhancing site aesthetics, educational outreach, and recreational potential of a site, thus meeting many project goals in one design.
