Water distribution systems in hilly areas are always divided into several zones due to the undulating terrain. The present approach of dividing water distribution systems lacks an assessment index and is characterized by a low degree of automation. With the building of a mathematical model, this paper introduces two indicators – pressure limitation and pressure variation – to enable the automatic division of the water supply pipe network. It prioritizes economic index as the objective function in the evaluation of the division of water distribution systems in hilly areas, and then selects the optimal division scheme by generic algorithm in a large number of candidates. The SY terrain in YW City China is used for verification. Compared to traditional water supply partition methods, this procedure is easier to operate time-savingly by staff and is more automatic.
From a purely visual perspective, some pipeline inspections are more awe-inspiring than others. This is especially true when everyone involved describes the pipe diameter as “monster-size,” clocking in at 210 inches in diameter.
A challenge of this magnitude requires fresh thinking from an inspection approach, especially when the subject pipe is so critical to the lifeblood of the Navajo Agricultural Products Industry (NAPI) farm.

Human health and biological safety problems resulting from urban drinking water pipe network biofilms pollution have attracted wide concern. Despite the inclusion of residual chlorine in drinking water distribution systems supplies, the bacterium is a recalcitrant human pathogen capable of forming biofilms on pipe walls and causing health risks. Typical drinking water bacterial biofilms and their response to different concentrations of chlorination was monitored. The results showed that the four bacteria all...
When there is a piping system that is needing to be repaired or fixed, it is always a hassle for you to have to deal with, as a homeowner, because there is so much damage that is done to your property. This has lead many homeowners to put off needing repairs done, specifically because they do not want to deal with the property damage and destruction around their home. However, with a newer advanced repairing system, known as “pipe bursting”, this repairs the damage within your pipes, without having to...
A “how-to” guide on preventing and thawing frozen pipes.
Astemperatures drop below freezing around the country, it’s important to be informed of the cold weather’s effect on your water pipes.When temperatures are below freezing, pipes in unheated areas are subject to freezing causing messy, and often expensive issues.
Just one burst pipe running at 4-8 gallons/min can cause tens of thousands of dollars in damage in a matter of minutes.
Water is unique in that it expands as it freezes....
Call it what you want, but a busted pipe spells nothing but T-R-O-U-B-L-E.
Now, the good news: There are several measures you can take now to avoid future pipe catastrophes, locate and eliminate potential break risks and prevent expensive emergency repairs.
This easy-to-follow guide offers helpful tips for engineers and water professionals looking to reduce the risk of pipe breaks, save valuable resources and avoid gigantic headaches.
