Stormwater Management

Jensen offers design-build solutions with hydrodynamic separators, detention and infiltration reservoirs, biofiltration systems, oil/water separators, sedimentation systems, diversion structures, drywells, and pump stations.

Stormwater management systems are precast concrete structures designed for the pretreatment, detention, retention, infiltration, and/or reuse of urban stormwater runoff. Engineers, contractors, and government agencies depend on our expertise in building the most advanced stormwater systems available for volume control, low impact development, and green infrastructure outcomes using best management practices.

The StormVault Biofiltration System is a versatile stormwater treatment solution designed to improve water quality. Using physical, chemical, and biological filtration, it effectively removes suspended solids, metals, nutrients, oil, and grease from runoff. As a low-impact development best management practice, it helps meet environmental regulations and sustainability goals.

The JDS Hydrodynamic Separator, made from durable precast concrete, efficiently captures total suspended solids (TSS), oil, grease, and petroleum pollutants. Designed to prevent scouring, even in high-flow conditions, it treats flows from 0.7 to 72 CFS and is certified and approved by various regulatory agencies.

Coalescing Oil Separators provide superior performance compared to traditional interceptors and sedimentation tanks. Jensen’s coalescing plate separators and media packs are designed to efficiently remove oil, grease, and total petroleum hydrocarbons (TPH) from stormwater and wastewater, ensuring compliance with environmental standards.
