SIOUX CITY (KTIV)-  After being delayed three times, a Wastewater Treatment Agreement between four Siouxland communities, has been deferred yet again.

In November of 2018, the City of Sioux City notified South Sioux City, Sergeant Bluff and North Sioux City, that they wanted to review the deals under which they send their sewage to the Sioux City plant.

The original notice was scheduled to be voted on back in December.

It was then deferred to February, then March, then to Monday.

Monday night, city leaders deferred it again, to August 2019.

Mayor Bob Scott says the agreements with those communities are outdated, and it’s time to start fresh.

A presentation was held Monday night ahead of the regularly scheduled council meeting, on the wastewater cost of service study results presented by HDR of Des Moines.

“They went over rates, and they went through those rate studies today with the sister cities and the industrial users,” said Mayor Bob Scott, Sioux City. “So, it’s just a continuing process is all.”

In the past, South Sioux City leaders have been considering building a wastewater treatment plant of their own.
