sarpy sewer

An area stretching roughly from 60th to 72nd streets south of Highway 370 will be the first to receive sewer infrastructure, according to a recommendation from the Sarpy County and Sarpy Cities Wastewater Agency.

The southern boundary of that area is winding, but may be described generally as following Platteview Road. The recommendation emerged after the agency chose one of three areas to begin a four-phase sewer installation project in southern Sarpy County that is expected to cost about $220 million to build and up to 50 years to complete.

The $220 million figure stems from a 2015 study, which, given the impact of inflation and additional infrastructure, is anticipated to be as much as $40 million higher in 2019 dollars.

Tax dollars, however, are expected to play no part in the project.

The entire cost, according to an earlier county study, is expected to be borne by user fees, connections fees and public-private partnerships.

The agency’s governing board announced June 28 that a Growth Management Plan had been approved that will execute an agreed timetable.

The timetable for installing sewer between 60th and 72nd streets, referred to in the agreement as Phase 1A ZC-3, is 2019-28, to be followed by Phase 1B, commencing in 2028, Phase 2 commencing in 2035 and Phase 3 commencing in 2044.

Sarpy County Board Chairman Don Kelly said the Sarpy sewer agency expects to have a contract signed by the end of this year, with construction starting in 2020 and completion set for 2024.

Kelly said the project is being advertised nationally.

“Everyone who is anyone in wastewater infrastructure will probably be interested,” he said.

Phase 1 will include improvements along the Highway 50 corridor intended to accommodate expected growth in Springfield and areas to the west between Springfield and Gretna.

Phase 1 is expected to cost $22.6 million in 2015 dollars, which is when the estimates were first presented. According to the U.S. Bureau of Labor Statistics Consumer Price Index, that figure in 2019 would be $24.4 million, an increase of 8 percent.

The 60th to 72nd streets area was selected as the first step because it will accommodate growth south of Papillion and west of Bellevue; because it carries the lowest estimated cost of the four construction phases; will require only three miles of newly paved road; and contains 220 acres of large lots, which is expected to make land acquisition easier.

The area is estimated to contain 1,760 acres of developable land.

The Sarpy County and Sarpy Cities Wastewater Agency is a public body governed by a board consisting of representatives from the Sarpy County Board and all five Sarpy County cities.

It was formed in September 2017 to solve the problem of a geographical ridge line that stretches from Gretna in the west to approximately 36th Street in the east. The ridge line prevents sewage from being pumped north into existing infrastructure.

Land south of the ridge line, therefore, which constitutes about half of the county’s land, has remained largely undeveloped during the past 50 years even as land north of the ridge line has developed steadily.

Wastewater flowing from the treatment plants will flow into the Platte River, which defines the southern boundary of Sarpy County.
