The expansion project's necessity can be attributed to three factors, each of which can be broken down into dollars.
According to the report:
- 55 percent of the project is necessary because of the city's growth needs through 2020. Cost: $22.3 million.
- 30 percent of the needs are attributable to new or anticipated environmental regulations from the Kansas Department of Health and Environment. That translates to $12.1 million.
- 15 percent would go toward maintaining the treatment system's overall reliability. Cost: $6.1 million.
The estimates represent a 10 percent cost reduction when compared to the city's previous $45 million estimate for the project.
Black & Veatch earned $125,000 for compiling the latest report.
