The goal of the distribution system is to supply customers with potable water at an adequate flow rate and pressure. The term “distribution system” describes the network of pipes, pumps, and storage tanks transporting water from its origin to its destination.
The water distribution system services a community’s buildings and land. This system’s engineered hydrologic and hydraulic components transport clean water from a treatment facility or wells to end users’ homes and businesses. There are different types of valves in water distribution systems that the flow of water.
A water distribution system is responsible for collecting, purifying, storing, and delivering water. Even if the system’s core operations are simple, the dynamic nature of the present and future needs means that the system rarely operates in its typical fashion.
Types of Water Distribution Systems
Adapting to shifting system needs has allowed for development of numerous water distribution models. The following system types are distinguishable in terms of their overall designs, yet you can merge them to cover a particular area.
Grid Iron System
Using a grid iron system is possible in areas where the water mains and branches have been mapped out and installed in a rectangular pattern. Because there are no bottlenecks, water moves quickly and efficiently through this setup. Some areas of the system may experience water-related issues, but others will continue to get a reliable water supply. This discharge will be adequate for firefighting purposes.
By shutting off the valve for that section of pipe, you can do maintenance work without disrupting service to the rest of the building.
On the other hand, ring systems are often set up along the outer highways and sub-mains that radiate from the primary connections. This type of water distribution system also uses a gridiron system to determine the flow pattern of the water. Water and connections can ring networks to originate from many locations.
Radial networks are typically found in locations that have delineated zones. The distribution reservoir is placed smack dab in the middle of each zone to ensure that all areas of the system have access to water. Because the properties’ water is delivered, radial systems have their one-of-a-kind quality. In addition, they can make the process of estimating pipe size easier.
Dead-end street networks are the most effective form of transportation in regions that lack a conventional roadway structure. Water distribution systems with only one outlet are economical and reasonably practical. They can more easily determine discharges and pressure due to the reduced number of valves that are required.
It is possible to determine the pressure and discharge in each pipe in a very straightforward and exact manner, which makes design calculations very easy to perform.
You can use the required demand of the population to inform the design of the sizes of the pipes used for the primary, sub mains, and branches. As a result, it will be possible to cut the project’s total cost.
How does an ideal distribution system function?
A working water system must meet a few minimum criteria. Examples of these are:
- The piping system must not degrade water quality.
- There needs to be enough pressure for water to reach all of the designated spots.
- To avoid waste and leakage, it must be airtight.
Water should be available to all customers, even if a portion of the system is being repaired. It should also be able to provide the water and pressure required for firefighting actions.
Common system issues
Leaks are a significant issue in nearly every type of water distribution system. While obvious leaks are easy to spot and fix, many more go undetected because they are hidden from sight. This method of passive leakage management is not effective in reducing leakage.
Those in charge of upkeep of water distribution systems have a more solid option for addressing leakage issues. If they pay for the services of leak detection experts, they can have the pipes frequently checked for any signs of water damage. These professionals have tools to find pipe and system leaks without digging them up. They have enough information to compute and analyze the state of the systems with relative ease, from which they can propose the next steps.
Losses in commercial value are another issue with water distribution systems. Because of this issue, the billed volume may drop, leading to a decline in income. The only way to stop the leaks and water waste is to track down every unlawful connection and water leak. The same goes for addressing issues and corrections related to metering, data management, and billing.
Water providers will further need to implement high-quality works, materials, and equipment in the design of system expansions/distribution (e.g., new network components already built as DMAs). To prevent tuberculation and encrustation, that should build sediment deposits; a water distribution system on a pipe layout is acceptable and has minimal water stagnation within the pipe.
