Sewer improvements and water tower costs to be felt, but not to the extent as first thought.
The Cassgram reports federal environmental regulations dictated that Plattsmouth fix the areas of the city where the sanitary and storm sewers merged and caused sanitary sewer overflow into the Missouri River during rain events. Studies on how to fix the combined sewer overflow (CSO) problem have been underway for a couple of years.
City Administrator Erv Portis prefaced his remarks to the city council this week by noting that the following numbers are in the “worst case scenario”—a situation where Plattsmouth gets no federal aid or grant money.
Several months ago, the first cost estimate engineers gave for all phases of the CSO fix was $7.37 million dollars and that the impact per ratepayer would be $19 per month.
That total cost has been revised downward to just under $6.2 million, said Portis.
With the lower cost projection and current borrowing rates from the state’s revolving loan fund, that per customer impact has been revised downward to $9.45 per month on a 30-year loan and in the neighborhood of $11 per month on a 20-year loan.
