What does the Water Quality Program do?

• We manage surface water quality within the City of Chattanooga
•  This includes both our natural water bodies, such as streams, creeks, and rivers and stormwater runoff
•  Stormwater runoff is excess rainwater that can't be absorbed when it falls on impervious or hard surfaces, such as streets and roofs. It picks up pollutants as it runs off these surfaces, then goes directly, untreated, into our water bodies.  
•  See the links above for our programs, with projects and announcements listed below and on this page.

What we don't do:  

We do not manage sewage or drinking water. Please see the bottom of the page for links to sanitary sewer and drinking water contacts

 The Water Quality Program Announces Green Grants!

The City's Water Quality Program (WQP) has created the Green Grants Program for property owners who seek to improve water quality and/or go beyond their Stay-on-Volume (SOV) requirement for a green infrastructure (GI) development or retrofit project.

The grant will provide businesses, institutions and other non-single family residential customers parital funding for the design and construction of green infrastructure projects on private properties.

Sunbeam Green Infrastructure Project

Description:

In order to alleviate the risk for potential flooding in the area, the Water Quality Program was tasked to provide a cost affect solution since the traditional grey infrastructure (underground pipe network) was limited given the severity of the slope.

This alternative design approach on this project was green infrastructure. By utilizing a green infrastructure approach, these features will mimic the natural water cycle, prior to development, allowing for ground water recharge.

Project Goals and Benefits:

· Filter pollution from stormwater runoff

· Protect our waterways from polluted stormwater runoff.

· Recharge local groundwater

· Provide opportunities for neighborhood improvements

· Improve aesthetics of the streetscape

· Create habitat for birds and butterflies

· Reduce demand on existing pipe and sewage treatment plant

· Slowing the flow by diverting into WQ swales to allow sediment and pollutants to settle out before the water is discharged into the conveyance system

· Minimize flooding during intense rain events

· Decrease impervious area

· Educate residents on stormwater water quality control measures

East Lake Water Quality Improvements Project is underway.

We are working to renovate East Lake Park's pond and water qualtiy features.  Do you live near East Lake Park?  Do you spend time in this awesome space?  A concept is being funded by the Lyndhurst foundation and a concept will be final this year.

Agawela Drive Stream Restoration

The City Of Chattanooga is completing a stream restoration of approximately 1,500 linear feet of an incised stream channel within an urbanized watershed of the City. The unnamed tributary to South Chickamauga Creek was deeply entrenched from the years of flashy, urban stormwater runoff. This contributed heavily to the sediment load in South Chickamauga Creek, a 303-d listed stream with a siltation TMDL. South Chickamauga Creek is also the only known location of the threatened Chickamauga Crayfish. Completing the restoration entails reconnecting the channel with the floodplain, installing multiple grade controls and establishing a meandering pattern within a tightly confined corridor.
