Summer floods will mean more land application of sludge this fall
October 24, 2008
This summer's flooding caused major damage to the Cedar Rapids wastewater-treatment plant, as well as to many others around the state. One of the items damaged at Cedar Rapids was the plant's sludge incinerator. As a result, the city is going to make unusually high use of land application
on farm fields to dispose of the sludge, since it's much cheaper than trying to send the sludge to landfills. Sludge that has been treated by anaerobic digestion
is a very useful form of fertilizer for crops like corn.
