Prestressed concrete cylinder pipe (PCCP) is a common variety of large-diameter concrete pressure pipe used for transporting water and wastewater. PCCP is typical manufactured according to the American Water Works Association (AWWA) standard C304. [ 1 ]
The pipe section is 3.65 m in diameter, and is mounted on a base that was a pre-cast control gate for the water race. Concrete ends were installed and a timber floor fitted to turn the pipe section into a storage space. The Pipe Shed has been used for various purposes including an explosives store. [17]
h f = head loss in meters (water) over the length of pipe; L = length of pipe in meters; Q = volumetric flow rate, m 3 /s (cubic meters per second) C = pipe roughness coefficient; d = inside pipe diameter, m (meters) Note: pressure drop can be computed from head loss as h f × the unit weight of water (e.g., 9810 N/m 3 at 4 deg C)
The efficiency, durability, ease, cost effectiveness, and sustainable properties [13] of these products have brought a revolutionary shift in the time consumed in construction of any structure. Construction industry is a huge energy consuming industry, and precast concrete products are and will continue to be more energy efficient than its ...
As the diameter of the reline pipe will be smaller than the host pipe, the cross-sectional flow area will be smaller. By selecting a reline pipe with a very smooth internal surface with an approximate Hazen-Williams Friction Factor C value of between 140–150, the decreased flow area can be offset, and hydraulic flow rates potentially ...

Cement-mortar lined ductile iron pipe is a ductile iron pipe with cement lining on the inside surface, and is commonly used for water distribution. Cement-mortar lined ductile iron pipe is governed by standards set forth by DIPRA ( Ductile Iron Pipe Research Association ), and was first used in 1922 in Charleston, South Carolina .
Vitrified clay pipe (VCP) is pipe made from a blend of clay and shale that has been subjected to high temperature to achieve vitrification, which results in a hard, inert ceramic. VCP is commonly used in gravity sewer collection mains because of its long life and resistance to almost all domestic and industrial sewage , particularly the ...
