Our system’s preliminary design takes our conceptual design and improves on quite a few components of it.

It has moved into a single chamber design with a weir between the inflow and outflow pipes. This design has 3 Plexiglas lids (for ease of access inside the vault for maintenance),  high strength concrete, a waterproof “Job box” (shown in green), a small NEMA type-4 enclosure, a ladder for access, and bolt fittings for each of the boxes and for the Plexiglas lid. The Job Box will store the sample collectors and the NEMA box will store the Arduino, a small computer the team has configured for measurement recording purposes. The vault sizing is as follows:

Since the Anderson Avenue group will not be designing the filtration of the system, we decided it would be a good step forward to look into various methods of filtration for the client to look at later.

Cartridge filtration was considered, which uses hydraulic head to filter stormwater through a sand-based cartridge system. This proposed system would use more than ten cartridges. From an estimate from Contech, this cartridge filtration system would cast upwards of $80,000.

The team also evalutated Hydrodynamic Seperators (HDS), but there was no size that would fit inside of the vault.

More filtration options are to be considered for the client at a later date.

This is the conceptual design created by the Anderson Avenue Design team during the planning phase of this project. It is a three chambered design with a projected 85% TSS (Total Suspended Solids) removal per rain event. It has a separate electronics enclosure within the vault itself. In case of a peak flow event, there is a bypass configuration routed under the electronics enclosure.

This system showcases a cartridge filtration system, single pane Plexiglas lid, and an 8 inch thick concrete enclosure.

Our group is designing a test bed to be installed by the City of Chattanooga as part of the stormwater and streetscape improvements to the Anderson Avenue area. The test bed will be installed in a permanent “vault” in the area designated by the City of Chattanooga. This test bed will evaluate aspects of stormwater flow and water quality using robust sensors. Data will be collected and sent through the City’s wireless mesh system to a database where the client can access the information gathered from the sensors.

This will be an adaptable vault, which will host many different kinds of filtration methods to be chosen at a later time by the client.This will be an adaptable vault, which will host many different kinds of filtration methods to be chosen at a later time by the client. Our team is providing a scalable, modular test-bed to house various storm water testing and monitoring equipment. We will provide a vault, sensors, software, and an observation lid.

This is the space created for the Anderson avenue team so we might have a place to post on the UTC web site. PLEASE,  feel free to update and develop this site at your leisure.
