Another year with heavy rainfall. Another year with flooding. And, another year of pumping raw sewage into the Mississippi River.
The all-too-familiar scenario is playing out again along the Bettendorf and Davenport riverfront as the Davenport Wastewater Treatment Plant struggles to cope with high flows – a combination of storm water runoff, flood water and sewage – resulting in the backup of interceptor sewer lines along the Bettendorf and Davenport riverfront.
Bettendorf activated its pumps along the riverfront near Leach Park and the Isle of Capri Casino June 29, according to reports filed with the Iowa Department of Natural Resources (IDNR), and in just the initial hours pumped 1.3 million gallons of raw sewage mixed with storm water into the river. The pumps have been pumping since, and a full tally of the sewage disposed in the river is expected when the pumps are turned off. Pumps were still on as of today (10/10) at three locations along the Bettendorf riverfront.
Davenport also reported bypassing of sewage June 30 at the River Drive and Howell St. lift station as well as 11 sewage back-ups in basements and nine sewage manholes overflowing between July 1 and July 3.
During the wet March-June period in 2013, Bettendorf flushed more than 200 million gallons of untreated sewage diluted by storm water into the Mississippi River.
