Current through Register Vol. 39, No. 2, July 15, 2024
(a)
				  Construction of a pre-settling reservoir shall be required if wide and rapid
				  variations in turbidity, bacterial concentrations, or chemical qualities occur,
				  or where the following raw water quality standards are not met: turbidity - 150
				  NTU, coliform bacteria - 3000/100 ml, fecal coliform bacteria - 300/100 ml, or
				  color - 75 CU. If impoundment of the water supply stream does not or will not
				  provide raw water of acceptable quality, a pre-settling reservoir located
				  outside the watershed or catchment area shall be required.
(b) The Department shall approve alternatives
				  to pre-settling reservoirs if a supplier of water demonstrates that engineered
				  pretreatment providing an additional treatment barrier to low raw water quality
				  will be installed and that the overall designed treatment process will comply
				  with all other applicable requirements of this Subchapter. Pilot plant studies
				  under Rule .0714 of this Subchapter shall be required to demonstrate treatment
				  effectiveness unless operational data demonstrating treatment effectiveness for
				  the variety of water quality that is experienced at the treatment facility are
				  already available.
(c) The
				  Department shall approve capacity increases at existing surface water treatment
				  facilities without addition or up-sizing of pre-settling reservoirs if:
(1) historical data or full-scale pilot
				  studies demonstrate that the plant will provide treatment in accordance with
				  this Subchapter without additional pre-settling; or
(2) the use of alternative technology
				  alleviates the need for additional pre-settling.

				  restrict the entrance velocity to 30 feet per minute or less.
(b) Reservoir Intakes. Where water quality
				  variations affecting the treatment process will occur at different depths of a
				  reservoir, the intake structure shall be constructed with multiple inlets that
				  can be readily opened and closed for selection of the optimum water quality
				  level. A bar screen or grating shall be provided, with the area of the openings
