Explanation of Stringent Limits
The Henderson WWTP is located on Nutbush Creek. U . S . G . S . flow
estimates indicate that streamflow is small ( 0.1 cfs) during 7Q10
periods relative to the design flow of the treatment facility (6.2 cfs) .
Streamflow below the Henderson outfall, therefore, is comprised almost
entirely of Henderson effluent. The DEM gathered field data during
similar flow conditions ( .2 cfs), which was used to calibrate a level
C QUAL-II model. These data indicated a high rate of deoxygenation
(1.5 base e/day) and a relatively low rate of reaeration (3.0 base e/day)
characterizes the stream below the outfall. These factors are largely
responsible for the stringent limits applied to the Henderson WWTP.
