Design drawings for proposed WWTPs or modifications to existing WWTPs shall, in addition to meeting the applicable requirements of Env-Wq 703.01 through Env-Wq 703.05, include the following:

1. (a) A location plan that shows the WWTP in relation to the sewerage, including topographic features to indicate its location in relation to streams and the point of effluent discharge; and

2. (b) Layouts of the proposed WWTP or proposed modifications to an existing WWTP that include the following:

   1. (1) Topography of the site using 2-foot contours;
   2. (2) Dimensions, elevations, and location of all existing and proposed WWTP structures;
   3. (3) Site boundaries including areas reserved for future expansion and all buildings or building lots within 600 feet of WWTP property;
   4. (4) A process and instrumentation diagram showing the flow of sewage, sidestream flows, and sludge through the WWTP units;
   5. (5) Piping, including any arrangements for bypassing individual units and the materials handled and direction of flow through pipes;
   6. (6) Hydraulic profiles showing the annual average, maximum day, and peak instantaneous flow elevations;
   7. (7) The high and low water level elevations of the water body to which the WWTP effluent discharges or is proposed to discharge;
   8. (8) A summary of WWTP and unit process design criteria, capacity, and sizing; and
   9. (9) A description of any features not otherwise covered by the technical specifications or reports.
