Barnhill Co., Inc and HB West, Inc. are at the forefront
of this field in eastern North Carolina and we
are committed to helping our community grow responsibly.
Our work with water supply transportation and
distribution involves the construction of pump
stations, water main lines, fire hydrants, meters
and house service lines. Transportation systems
address the controlled movement of bulk quantities
of water for relatively long distances. Distribution
systems address the delivery of water through
pipe networks that serve urban communities.
Water distribution systems are generally designed
to adequately satisfy the water requirements for
a combination of domestic, commercial, industrial,
and fire-fighting purposes. The system should
be capable of meeting the demands placed on it
at all times and at satisfactory pressures.
Wastewater systems are usually designed as open
channels except where lift stations are required
to overcome topographic barriers. The driving
force for open-channel flow is gravity. Our work
with sewer systems involves the installation of
gravity sewer lines, force mains, lift stations,
manholes, storm water drainage systems, and collection
and pumping systems.
The collection and movement of surface drainage
and waste flows from residential, commercial,
and industrial areas pose problems of a different
nature from those for water supply. Waste must
be transported from the point of collection to
the treatment or disposal area as quickly as possible
to prevent the development of septic conditions.
Natural Gas Distribution
Our work with natural gas lines involves the construction
and installation of piping for distribution. We
perform this work in conjunction with the construction
of new facilities needing supply lines for natural
gas, as well as, gas supply for municipalities
and private developers. Gas transportation between
cities is usually effected by high-pressure lines
operating at pressures of several hundred pounds
per square inch, and the gas pressure must be
reduced to the distribution pressure as it enters
the distribution system. The pressure is further
reduced at each service connection by the installation
of a regulator.
