         3. (iii) the dimensions of each wastewater treatment unit;
         4. (iv) all mechanical, electrical, and construction details; and
         5. (v) a hydraulic profile of a treatment facility at both design and peak flows.
      2. (B) The construction drawings may include plans for future expansion of a facility.
      3. (C) The construction drawings may include a clarification of any complex details of pipe systems by including an isometric flow diagram.

   3. (3) The specifications for a material alteration or expansion of an existing collection system or treatment facility must include technical descriptions of all equipment including:

      1. (A) the quantity and sizes of any equipment;
      2. (B) any applicable materials specifications;
      3. (C) testing requirements; and
