Ask an Engineer: Stormwater Water Treatment Units

Jodi Beuder Ask an Engineer, Blog, Jensen Water Resource Blog, Stormwater

A new series from Jensen Precast and its Water Resources Division, Ask an Engineer touches upon complicated topics and queries that have been asked of our Engineering Team members. Much like a Frequently Asked Questions (FAQ) section, Ask an Engineer will address questions that our Engineers face more often than other inquiries. This Ask an Engineer session is with our Stormwater Systems Division Director, Walt Stein P.E., who answers this common question about Stormwater Treatment Units: How do you keep a stormwater full capture device from filling up? Watch this video to hear Walt’s question, or read below for his …

Blue Skies and Dirt

Project Lifecycle Day 5: When you build a beautiful precast concrete structure for a massive underground project, does it hurt to watch your work covered up in dirt? As phase one of the 307’ x 180’ x 12’ Lakewood Stormwater and Runoff Capture Project comes to a close in Southern California, phase two has already been excavated, and the dug-up dirt from phase two is used to cover up phase one. Good use of resources, eh? No one’s singing the “Subterranean Precast Blues” in Lakewood. When your work goes undercover of dirt it means you’re in the homestretch. Only blue skies …

Gaining the Corbel Edge – Mayfair Park, Lakewood, California

Nicholas Drake Blog, Stormwater

Project Lifecycle Day 4: Landing 16’ x 8’ x 10” slabs onto the jutting corbels of box culvert modular sections takes fortitude, finesse, and one of the best designs precast concrete has to offer. It’s a match made in Lakewood, California. Gaining the corbel edge means less concrete and more storage capacity for stormwater projects like the one being built in Mayfair Park. “Alternating between rows of box culvert and top/bottom slab sections reduces the amount of concrete per cubic foot required to attain a target storage capacity within a given three dimensional space,” says Vanessa Gallo, PE, Jensen Precast …
