Lagoon Renovation Mandates from the DNR  - Iowa Department of Natural Resources -  required the City of Norway to update its existing sanitary sewer system. The City Council engaged the engineering firm of Snyder & Associates to design a new system.  Once the DNR approved our plan to use a system created by NitrOx, - a cold-weather ammonia removal system -  to bring our sanitary sewer into compliance with State mandates, bids were sought from qualified contractors.  In October of 2017, the bid of $2,285.000  was accepted from Boomerang.  Work at the Lagoon started in late April of 2018, and by June, tons of earth had been moved and yards of concrete had been poured. From July of 2018, to the end of March 2019, work on the project proceeded sporadically; then work began on installing a new 15” main sewer line to connect the City to the Lagoon. During April and May of 2019, most of the new main sewer line was installed and much of the electrical wiring and controls were installed at the lagoon. By early June of 2019, the new sewer line had been connected, later that month, two new Pumps were installed at the Lagoon’s Lift Station. By early November 2019, the lagoon was being dredged of sludge so that the required renovation of the old lagoon could proceed; extensive  ground work still remains to be completed.
