due to sediment, nutrients, and low dissolved oxygen.  Since then, MWSD has implemented the 
following projects and actions specifically directed at improving water quality in the Stones River 
Watershed. 

 

Expansion of capacity and capability of the SCWWTP to include oxidation ditch activated sludge, 
tertiary filters, ultraviolet light disinfection, post aeration, and solids dewatering. 

 

Operational modifications to aeration of the oxidation ditch to optimize nitrification, 
denitrification, and phosphorus removal by luxury uptake. 

 

Regulatory overview through passage of three City ordinances (2005-2008) addressing site 
control runoff, stream buffers, and post construction stormwater treatment, and imposed a 
stormwater user fee in 2007 to fund stormwater management projects 

 

Construction site permitting and inspections including issuance of 457 Land Disturbance Permits 
(LDPs) from 2008-2015, of which 228 LDPs (est.) encompassing 1341 acres were on the _3000 
segment 

 

Corrective actions in the field including location and mitigation of 13 illicit discharges in the 
WFSR _3000 watershed (2008-2015).  Sources included food vendors on Square; truck washing 
at truck repair business; gas station/markets 

 

Post-construction stormwater control measures (SCMs) including installation of sediment 
removal and flow control facilities at 64 sites totaling 735 acres in the WFSR _3000 watershed 

 

Street sweeping, initiated in 2009, has collected 6554 tons of material including 3211 tons from 
the WFSR _3000 watershed.  An additional 820 tons of material has been vacuumed from storm 
sewers 

 

Education and public participation events in the 2008-2015 period including  

Tree Days encourage planting of trees alongside streams 

o

 

Lytle Creek (2010, 2014); 235 riparian property owners rec’d information; 1800 trees 
distributed  

o

 

Upper WFSR (2013); 134 property owners received mailer; 600 trees distributed 

o

 

Educational brochures on stormwater runoff management practices mailed to restaurant 
operators (375),  landscaping companies (15), and  pressure washing businesses (9) 

These actions have produced dramatic improvement in SCWWTP effluent quality and WFSR water 
quality. Semi- annual hydrologic and biological assessments of the WFSR initiated in 2013 have shown 
significant improvements in stream health as measured by the Total Macroinvertebrate Index (TMI).  
Results reported to the State in 2015 are expected to result in a delisting of perhaps 2 stream segments 
of the WFSR from the 303d list. 

The City is continuing its proactive approach to growth management, initiating the development of a 20 
Year Comprehensive Plan (Murfreesboro 2035) in 2015.  In concert, MWSD has commissioned the 
development of a Water Resource Integration Plan (WRIP) as a companion study.  The WRIP will: 

 

Look holistically at the management of water (drinking water, wastewater, repurified water, and 
stormwater) within the potential service areas of the MWSD; 

 

Coordinate with the City’s Comprehensive Plan, so that the goal of facilitating growth will 
encompass affordable and sustainable water management.
