There is little one can do about this type of pollution except to wait and allow the waters to cool down to biologically harmless temperatures before being discharged into some aquatic system. If the volume of heated waters is manageable they can be passed over a system of cascades or through fountains which causes rapid cooling. To handle large quantities of heated effluents large tanks or reservoirs should be constructed to retain the water for a little longer time. After the waters have cooled down to a tolerable temperature, they may be released in natural water bodies. It is advisable to discharge the heated waters into some lotic system, wherein active churning occurs due to flow of water which causes rapid cooling, instead of a lentic system.
