stormwater solutions engineering

What stormwater solutions engineering does

Stormwater Solutions Engineering, LLC (SSE) was a private civil engineering firm founded in 2002 and headquartered in Milwaukee, Wisconsin, that specialized in sustainable stormwater management, water quality, and environmental compliance services. The firm operated across the full project lifecycle — planning, analysis, design, permitting, construction administration, and post-construction maintenance and inspection — serving two primary segments: municipal and property management clients requiring stormwater system compliance, maintenance, and SWMP/SWPPP recertification, and engineering design clients requiring cost-effective drainage, flood management, and integrated site design for development projects. Its service catalog spanned stormwater management, repairs and rehabilitation (including trenchless pipe repair methods such as CIPP, slip lining, and spin casting), wastewater management, lift station services, green infrastructure (bioretention, permeable pavement, regenerative stormwater conveyance), FEMA floodplain analysis, NPDES/MS4 permitting, geotechnical assessments using ERT and GPR, GIS mapping, and water quality testing.

The firm's revenue mechanics relied on negotiated professional engineering services contracts and maintenance/repair engagements with municipal and private clients; pricing was not publicly disclosed and no enterprise customer logos or volume-based pricing models were available in the source material. SSE operated as a single-office regional firm for 21 years before being acquired by AQUALIS, a nationwide sustainable water management company, in March 2023. Following the acquisition, SSE's capabilities were integrated into AQUALIS's broader five-line service platform (Stormwater Management, Wastewater Management, Sustainable Water Engineering, Compliance & Consulting, and Water Quality Testing), and SSE no longer operates as an independent entity.
