Wastewater:

• Recent initiatives for WWTP staff to encourage full scale nitrification has led to drastically improved bacteriological settlability, poly saccharide formation, and effluent quality. All while influent BOD concentrations have not decreased. Ammonia nitrification is a costlier way to operate an activated sludge process, but it does seem to be a large improvement for flocculation, a chronic issue at this facility. 
• Collection system crews have been cutting roots, cleaning catch basins, televising sewers, and assisting street department construction staff as needed. 
• Maintenance and Collections crews have been performing seasonal lift station cleaning work. This will ensure optimal lift station performance. 
• Ellingson Trenchless alongside A1 excavating is approx. 90% complete with the river crossing force main boring. The current plan is to do the HDPE force main pipe pull back on 8/3. This will complete Ellingson Trenchless’ work in the City.  
• Recent plant performance improvements have led to staff taking final clarifier #2 offline. This will allow for a much needed inspection and cleaning of the equipment. 

• Summer biosolids hauling was completed on 7/12. City staff members hauled 59 dump truck loads (or 784 wet tons) of biosolids to a local farmer. This created enough storage capacity to get through the rest of the summer.
