KAUKAUNA, WI (WTAQ-WLUK) — Kaukauna Utilities broke ground on a transformative project that will build a state-of-the-art water treatment system.

Officials gathered for the groundbreaking ceremony for water treatment plant #1 at 807 Boyd Avenue Tuesday.

The system employs reverse osmosis or nanofiltration technology. The enhanced treatment process will significantly reduce water hardness for residents and businesses in the city.

With the adoption of reverse osmosis or nanofiltration, customers can anticipate improvement in water quality, translating to reduced buildup on appliances and fixtures, as well as prolonged appliance lifespans. Moreover, while the use of water softeners remains a personal preference, customers opting to bypass or remove their softeners stand to benefit from reduced monthly expenses on salt and maintenance.

While this project will lead to higher water rates, the anticipated savings on customer expenses are expected to produce an overall reduction in costs, officials say.
