Stormwater Problem:

The newly built library is five stories and has about 40% more space than the old library. It has a Starbucks and more than 200 computers. But in addition to a large technical presence, the library needed to meet a practical application – collecting water runoff. Because of the increased size of the building, it was essential to make good use of green space, and the school intends to use the water storage to provide irrigation to Chamberlain Field.

Stormwater Solution:

This project used an innovative treatment train approach, with both pre-treatment harvesting and storage. The Aqua-Swirl AS-2 was used to pretreat water before entering a modular underground storage product, Stormtank, which is manufactured by Brentwood Industries and is buried under the library grounds. The Aqua-Swirl AS-6 treats stormwater runoff and is plumbed to an AquaShield Rainwater Harvesting cistern, which stores rainwaterfor irrigation. These tanks also collect HVAC condensation, reducing the overall amount of stormwater runoff. UTC hopes that once completed, the library will achieve Silver LEED certification.

“All the AquaShield flow units worked really well combined with the Brentwood retention products. I had never done the underground systems that way, but it went smoothly. It was actually a pretty humdrum project. Considering the massive size and scope, couldn’t have asked for it to be better. AquaShield really worked with us the whole way to make everything come together. The finished library is the crown jewel of the campus.”
