mgd. In 2005, approximately 40 mgd of treated wastewater was discharged into the
Lower Mississippi River watershed from these 12 facilities. Smaller WWTPs account for
16% of the combined capacity of WWTPs discharging to surface waters in the Lower
Mississippi River watershed. This would equate to an annual average flow of 15 mgd if
these rural communities grew to use the full capacity of their WWTPs.
