Sewer/Gravity/Force Main Installation (Typical)

Pursuant to 9VAC25-790-360, the following setbacks/construction standards must be met.

1. Sewers entering or crossing streams shall be constructed of watertight pipe. The pipe and joints shall be tested in place and shall exhibit zero infiltration. Sewers laid on piers across ravines or streams shall be allowed only when it can be demonstrated that no other practical alternative exists.

Such sewers on piers shall be constructed in accordance with the requirements for sewers entering or crossing under streams. Construction methods and materials of construction shall be such that sewers will remain watertight and free from change in alignment or grade due to anticipated hydraulic and physical loads, erosion, and impact.

2. No sewer line shall pass within 50 feet of a drinking water supply well, source, or structure unless special construction and pipe materials are used to obtain adequate protection. The proposed design shall identify and adequately address the protection of all drinking water supply wells, sources, and structures up to a distance of 100 feet of the sewer line installation.

3. Sewers shall be laid at least 10 feet horizontally from a water main. The distance shall be measured edge-to-edge. When local conditions prohibit this horizontal separation, the sewer may be laid closer provided that the water main is in a separate trench or an undisturbed earth shelf located on one side of the sewer and the bottom of the water main is at least 18 inches above the top of the sewer. Where this vertical separation cannot be obtained, the sewer shall be constructed of water pipe material in accordance with AWWA specifications and pressure tested in place without leakage prior to backfilling.

The hydrostatic test shall be conducted in accordance with the most recent edition of the AWWA standard (ANSI/AWWA C600-82) for the pipe material, with a minimum test pressure of 30 psi.

4. Sewers shall cross under water mains such that the top of the sewer is at least 18 inches below the bottom of the water main. When local conditions prohibit this vertical separation, the sewer shall be constructed of AWWA specified water pipe and pressure tested in place without leakage prior to backfilling, in accordance with the provisions of this chapter. Sewers crossing over water mains shall:

a. Be laid to provide a separation of at least 18 inches between the bottom of the sewer and the top of the water main.

b. Be constructed of AWWA approved water pipe and pressure tested in place without leakage prior to backfilling, in accordance with the provisions of this chapter.

c. Have adequate structural support to prevent damage to the water main.

d. Have the sewer joints placed equidistant and as far as possible from the water main joints.

5. No water pipe shall pass through or come into contact with any part of a sewer manhole. Manholes shall be placed at least 10 feet horizontally from a water main whenever possible. The distance shall be measured edge-to-edge of the pipes or structures. When local conditions prohibit this horizontal separation, the manhole shall be of watertight construction and tested in place.

Pursuant to 9VAC25-790-380, the following cross connection standard must be met.

C. Water supply. There shall be no cross connection between any potable water supply and a sewage pump station which under any conditions might cause contamination of the potable water supply. Any potable water supply brought to the station shall comply with conditions stipulated in the Virginia Waterworks Regulations (12VAC5-590). Where conditions do not warrant the installation of an approved reduced pressure zone backflow prevention device on the water supply line to the pump stations, other approved devices may be considered on a case-by-case basis.

Pursuant to 9VAC25-790-440, the following standards associated with force main materials, connections and installation must be met.

Materials. All pipe used for force mains shall be of the pressure type with pressure type joints. The force main shall be constructed of materials with a demonstrated resistance to deterioration from corrosion, acidity, and other chemical action.

1. Consideration should be given to the use of inert materials or protective coatings for either the receiving tank or gravity sewer to prevent deterioration as a result of hydrogen sulfide or other chemical attack. These requirements should be provided for all force mains.

2. All force mains shall be tested at a minimum pressure of at least 50% above the design operating pressure for at least 30 minutes. Leakage shall not exceed the amount given by the formula contained in the most current AWWA Standard C-600.

Installation. Class A, B or C bedding (ASCE Manuals and Reports on Engineering Practice—No. 36, 1974 and the WPCF Manual of Practice—No. 9, 1970) or AWWA pipe installation conditions 3, 4 or 5 (ANSI/AWWA C600-82) shall be provided for installation of pipelines in excavated trenches. Installation of pipelines of flexible materials shall be in accordance with recognized standards.

Force mains shall be sufficiently anchored within the pump station and throughout the line length. The number of bends shall be as few as possible. Thrust blocks, restrained joints, or tie rods shall be provided where restraint is needed.
