The recommended long-term solution is to tap into cutting edge technology that uses "beneficial re-use of wastewater" through a cleaning system, the wastewater will be disinfected and returned to irrigate the golf course at Tansi. The golf course currently uses 26 million gallons of irrigation water from Lake Hiawatha annually. After filtering and disinfection, the new wastewater will be returned to Lake Hiawatha and be much cleaner than the current lake water. The wastewater being discharged into Lake Hiawatha will be ororless in such a small amount that it will not affect plants, fish, or fowl that are using the lake.
A membrane treatment process described as a "Bio-reactor" will be installed at the new maintenance area to filter, and disinfect the wastewater, creating a clean effluent. "The footprint of the unit is around 20' by 20' and does not require much additional yearly maintenance other than cleaning," according to Burgess. Total cost of both projects will be around $856,000.
