16:32, 24 June 2022 Camrenbt talk contribs created page PVC in Small, Low-Hazard Dam (Created page with "<div style= "text-align:center;">''Message: Iron pipes with downstream valves are often in surprisingly good condition...but not always.''</div> ----</br> PVC pipe is not as commonly used due to concerns with lack of watertightness and other inherent disadvantages. The major disadvantage with PVC pipe is the bell and spigot joint connections. This type of joint connection has the potential for leakage or can separate as the embankment dam settles. The bell and spigot jo...")

Common replacement pipe material types include Corrugated Metal Pipe, Concrete Pipe, and Plastic Pipe. Several important questions to ask include: #Is the existing means of control adequate? Is the gate / valve in a good condition, location, with no operational problems? If not, an evaluation of outlet configurations should be first. #The next ch...")

This zone can act both as a drain to carry off water and as a filter to intercept soil particles being transported by the water. A filter diaphragm is an important component of design for both new construction and the renovation of older emb...")
