Wastewater treatment options
is a costly business. Once wastewaters (taken here to mean any combination of domestic sewage and industrial effluents) are produced and collected in sewerage systmens, then treatment becomes a necessity.
It is important to note that reducing the volume of wastewater produced and/or avoiding the need for sewerage and treatment in the first instance has many advantages; the decision to move away from properly
implemented on-site sanitation should not be taken lightly.
