All installations shall be in strict accordance with the International
Building Code (IBC) codes, the Virginia Department of Health, Waterworks
Regulations, adopted June 23, 1993, and the Amelia Courthouse Sanitary
District "Rules and Regulations and Construction Specifications and
Standards."
No deviation from the Rules and Regulations and Construction Specifications
and Standards and construction details approved by the District shall
be allowed, unless specifically authorized in writing by the District.
Although constructed as parcels or subsystems, all water mains and
related facilities of all proposed developments shall be approved
on the basis of their functional integration with the District's total
water system.
The District reserves the right to determine the size of any proposed
water main that will be accepted into the system.
All water mains shall be provided with a minimum of not less
than 36 inches of earth cover measured from established finished grade
to the top of the pipe to prevent freezing.
General. There shall be no physical connection between a public or
private potable water supply system and a sewer, or appurtenance thereto
which would permit the passage of any sewage or polluted water into
the potable water supply. No water supply or distribution pipe shall
pass through or come in contact with any part of a sewer manhole.
Further, no water supply line shall be installed closer than 10 feet
horizontally to septic tanks and 30 feet to septic tank tile lines.
It shall be well recognized that water supply lines and structures
shall be kept remote from any existing sewers.
Under normal conditions water lines shall be laid at least 10 feet
horizontally from any existing sewer line or sewer manhole wherever
possible. The distance shall be measured edge-to-edge.
When local conditions prevent a horizontal separation of 10 feet,
the water line may be laid closer to a sewer provided that the invert
of the water line is at least 18 inches above the top of the sewer
and installed on a undisturbed earth shelf. Where this vertical separation
cannot be obtained, the sewer shall be constructed of AWWA approved
water pipe, pressure tested in place without leakage prior to backfilling.
The sewer manhole shall be of watertight construction and tested in
place.
Under normal conditions water lines crossing over sewers shall be
constructed to provide a separation of at least 18 inches between
the invert of the water line and the top of the sewer wherever possible.
When local conditions prevent a vertical separation as described
above, sewers passing over or under water lines shall be constructed
of AWWA approved water pipe. Water lines passing under sewers shall
have a vertical separation of at least 18 inches between the invert
of the sewer and the top of the water line and be installed centering
the water line and sewer line at the point of crossing so that the
joints are equidistant and as far as possible from the sewer. Adequate
structural support shall be provided to prevent excessive deflection
of the joints and settling on and breaking of the water line.
