There seem to be many mechanical suggestions to resolve this issue. All are practical and solid. The waste treatment facility IS the problem. Chemicals are expensive. Water is a resource. Pathogens are a reality. The waste and or sludge/slur are valuable nutrients. Your farmers are in desperate need of this . Please do not use water to make the problem worse. Do use oxygenation cycle but stop any chlorine, DO use Archaea microbes to reduce waster (organic compounds) then refit waste nutrient rich water for agricultural use. No smell, no pathogens, agricultural land or reforest. Change desert back into ag or forest. Simple solution for a hard problem. Good luck.
