The wastewater treatment
plant currently treats an average of five million gallons per day and discharges the treated water to the Arkansas River. The treatment process is a multi-stage process that reduces or removes:
- Disease-causing organisms
- Organic and inorganic matter
- Other wastewater pollutants
- Suspended solids
Every year, approximately 500 tons of sludge are produced and are, through the treatment process, converted from an undesirable waste to an environmentally-friendly soil enhancer.
The city currently has 1,200 acres of private farm land permitted for the application of the treated sludge. At these application sites, various crops are grown and the nutrients in the sludge are used by the crop just as commercial fertilizer would be used.
