City needs third phase for more wastewater capacity - KTIV News 4 Sioux City IA: News, Weather and Sports

After fighting a third phase of the wastewater treatment plant, Sioux City officials have given in to the idea that they'll need to expand capacity more at the plant to meet state requirements.

The city has spent years upgrading the plant along Highway 75.  The city's Public Works director says it's not working up to the 20-million gallon capacity it was designed for, because parts of the process weren't updated to handle that flow.

Upgrades, so far, have cost the city $72-million.

This final phase is expected to take care of any outstanding issues and cost five-million-dollars.

"We will also improve some of the systems that are aged or need some attention, that weren't taken care of in previous projects," said Jade Dundas.

Work should start within the next two months and take a year and-a-half to complete.
