AWWA JAW10889

A question was recently addressed by the Ohio River Valley Water Sanitation Commission (ORSANCO) regarding the municipal and industrial discharges to the Ohio River from water treatment plants. Since 1970, the commission's requirements for wastewater treatment from municipal and wastewater sources have been stipulated by Pollution Control Standard 1-70 and 2-70. However, on examination, enforcement of the regulations did not appear to be uniform, if they were followed at all. A study was authorized in 1981 to examine the problem. In 1980 dollars, total annual costs for state-of-the-art removal and disposal of solids were estimated for a typical 37-ML/d (10-mgd) treatment plant employing waste handling processes at $108,244 ($29.65 per 3.7 ML/d [1 mgd] to $434,599 ($119.07 per 3.7 ML/d [1 mgd]). Due to the significant sums of money involved and without any discernible improvements in water quality, the requirements for water treatment plants to remove waste solids were considered not to be appropriate. A new resolution, designed to simultaneously assure protection of water quality and allow maximum flexibility to the states, has been proposed to establish consistency. If this proposal is adopted, the commission can demonstrate that controls should properly reflect balanced considerations of environmental benefits and associated costs. Includes table, figures.
