Section 220. Compliance with Manual of Practice

A. The design guidelines set forth in the Manual of Practice (Part III) specify general criteria for the design and construction of waterworks. The division may impose standards or requirements which are more stringent than those contained in the Manual of Practice when required for critical areas or special conditions. Any such special standards or requirements with a federal mandate shall take precedence over the criteria in the manual and will be items which warrant careful consideration at the preliminary engineering conference, referenced in 12VAC5-590-200 B.

B. Designs submitted for waterworks must demonstrate that the system will adequately safeguard public health. Submissions which are in substantial compliance with the Manual of Practice or additional requirements of the department, as noted above, will be approved. Justification for a design may be required for those portions of the submitted design which differ from the criteria of the division, the Manual of Practice, or accepted engineering practices. Deviations from "shall" criteria which the design engineer, in his judgment, believes to be substantial in nature shall be identified and justified. The division may require changes in designs which are not in substantial compliance with the manual and which are not adequately justified by the engineer owner.

C. Final, complete, and detailed plans and specifications submitted in accordance with the provisions of 12VAC5-590-200 and 12VAC5-590-210 will be reviewed by the division as soon as practicable upon receipt. Such plans and specifications will be approved if they demonstrate substantial compliance with the design criteria set forth in the Manual of Practice and if the waterworks as constructed or modified, will be able to function in compliance with the operating regulations set forth in Part II. One set of the approved plans and specifications will be stamped by the division and returned to the owner.
