These design guidelines have been prepared to assist engineers preparing plans for water and sanitary sewer projects in Prince George County, Virginia. These guidelines are for use by experienced design professionals. Variations will be permitted based solely on sound engineering practice and will be reviewed and approved by the County Utility Department on an individual basis. Such variations must be requested in writing along with sufficient documentation supporting the request.

Public sanitary sewers, private sewer 8" and larger (with manholes and service laterals), and public water mains shall be designed by a Professional Engineer licensed in accordance with the requirements of the Code of Virginia or a Professional Surveyor with a Class B license issued by the State of Virginia. Designs shall be in accordance with the Latest Edition of Waterworks Regulations and Sewerage Regulations, Virginia Department of Health, Commonwealth of Virginia and any other local, State or Federal agencies having jurisdiction. The engineer shall also comply with the requirements of the County's subdivision and utilities ordinances as they pertain to water and sewer systems. It is the responsibility of the Engineer to inform developers of the contents as set forth in the applicable local ordinances as it relates to the project under review and consideration by the County Engineer.

Prior to construction of public water and/or sanitary sewer facilities, construction drawings for the proposed facilities must be submitted for review to the County Engineer, Prince George County. The construction drawings must be in a form acceptable to the County Engineer and be submitted in three copies. If deemed necessary by the County Engineer, the developer or his agent shall submit an overall plan for the water and/or sanitary sewer systems for the proposed development. The plan must be submitted to the County Engineer for review and approval at least thirty (30) days prior to submission of any schematic, tentative subdivision, construction or site plan for the property. A detailed checklist of plan requirements can be found in Appendix 11 of this document.

It is suggested that, for complex projects and projects which may require special Considerations, the engineer arrange a meeting with the County Engineer to discuss the approach to be taken to supply water and sanitary sewer service. All water and sanitary sewer systems must be located and sized properly to serve the entire service area in conformance with the County's approved Water and Wastewater Facilities Plan.

It should be noted that where it is determined that water or sanitary sewer lines are necessary to serve property beyond the subdivision or development in question, the developer will be required to design and construct his system, properly sized and at an appropriate location, to permit future extensions to be made at the limits of the subdivision or development in question. The system must terminate, at all points in new development, to the adjacent and/or upstream properties to be served by the system in the future. Elevation of the sewer system must be designed such that future extensions are taken into consideration to allow service to all the area which naturally drains towards the system. Public water systems must be designed and constructed along major roads and/or through the development to facilitate for future extensions. In selecting routes for water and sanitary sewer extensions, the Department requires that the location must be such that it maximizes the potential for serving areas of existing and/or future developments.

The developer must enter into a contract with the Board of Supervisors before any work begins. A copy of the Utility Contractor's bid proposal as accepted by the developer is required to prepare the contract. The Unit Price Bid Proposals shall be based on the approved water and/or sanitary sewer plans. All work must be performed by a Class A licensed contractor and/or as deemed acceptable to the County Engineer. Refunds shall be considered for all extensions of the public water and sewer systems where –

  1. The County Engineer has required that additional water or wastewater lines be installed to serve property beyond the furthest property line of the developer's property; or 
  2. The developer is required to oversize the water or wastewater
    line being constructed to serve his development.
