Best Management Products, Inc.
Since 1999, more than 80,000 BMP SNOUT hoods have been put in service to help communities comply with stormwater quality regulations. This system reduces trash, floatables, oil and sediment from stormwater discharges. It is also a high-performance pre-treatment option for water harvesting, stormwater retention and recharge systems.
BMP’s accessories such as the Bio-Skirt, the Stainless TrashScreen and our new Turbo Plates add flexibility and extra cleaning power. The most popular option for the SNOUT is the Bio-Skirt, which increases hydrocarbon removals, including emulsified oils and PAHs. The Stainless TrashScreen is an accessory that helps to meet Full Trash Capture requirements for Trash TMDLs.
Our Turbo Plates reduce turbulence and velocity in the structure and greatly increase sediment capture and retention. Design information, CAD drawings and pricing can be found at bmpinc.com or call 800-504-8008 for assistance. Celebrating our 20th anniversary, all products are proudly made in the USA.

Presto Geosystems’ GEOPAVE porous pavements were utilized for parking and walkways with other environmental and sustainable products at a Wisconsin nature preserve, The Ridges Sanctuary, in their pursuit for USGBC LEED Platinum rating.
Protecting Lake Michigan’s watershed was a primary concern at this facility’s location adjacent to the lake’s western shores. The porous pavements were an important part of the overall plan to protect the waters against the negative effects of stormwater runoff on water quality. The GEOPAVE system, infilled with highly porous stone, allows water infiltration, and acts as a natural, onsite stormwater retention system, storing stormwater in its aggregate base after rain events and allowing for natural percolation. GEOPAVE pavements are designed to accept everyday traffic from cars, trucks and emergency vehicles.

During a major rain or tidal event, the water pressure can be powerful enough to force up and dislodge a manhole cover. This creates a hazard for both motorists and pedestrians. The STORMSURGE Access Assembly solves this problem by allowing water to flow. During a storm surge or backflow event, the cover can lift up to 16 degrees, enabling water to flow out and relieve the pressure. The locking arm and hinge restrain the cover and allow it to properly seat itself after the event. Made in the USA, it is traffic rated and exceeds the 40,000-lb proof-loading requirements of AASHTO-M-306.
