Leak Detection, Leak Repair & Pipe Replacement
Wastewater Treatment: Contamination & Leakage
Wastewater leak is a serious problem as there is a high possibility that it can contaminate portable and drinkable water resources. Leakage in wastewater not only is harmful to humans but can also be quite expensive to fix. Thus to combat this problem there are many developed methods available in the market to detect, locate and repair leaks in wastewater treatment systems.
Therefore if you are looking for the most appropriate wastewater leak repair and pipe replacement solutions then we at IDS Water have it all and much more. Our goal is to connect you to numerous suppliers who are reputed in distribution of all kinds of water technology related testing and components. However, before you go through our suppliers and vendors directory we are sure that you would want to understand about wastewater leakage, detection, leak repair and pipe replacement better. Continue reading this article to know more about it.
What is Wastewater Leakage?
Poorly constructed or old pipelines, poorly maintained valves, mechanical damage and inadequate corrosion protection are some of the reasons that contribute to wastewater leakage. One major effect of wastewater leakage is possible water contamination of drinking water resources.
Thus of the numerous options that are available for water conservation, wastewater leak detection is the most important step. If public and private water utility agencies adopt appropriate methods, wastewater leaks can be avoided. Even if leaks do occur efficient leak repair strategies can be adopted.
Benefits of Leak Detection, Leak Repair & Pipe Replacement
Regular leak detection exercises will help in fixing leaks, if any at the earliest. This can help in avoiding seepage of wastewater into water resources and can avoid pollution. Also, the economic benefit of early leak detection is higher.
Some other potential benefits of leak detection, leak repair and pipe replacement include:
- It helps in early detection of leaks and helps in responding more quickly to emergencies and to set priorities for replacement or rehabilitation leak repair programs;
- It results in more efficient use of existing wastewater treatment plant
- Reduces the risk of wastewater leakage thus improving environmental quality
- It helps in reducing any property damage by avoiding instances of sewage spillage
- It reduces the risk of soil, environment and water contamination and pollution.
Causes of Leaks: Pipe Leakages & Leak Detection
Wastewater is treated and delivered to the distribution system with the intention of being distributed and sold to the public. However, all of the wastewater does not undergo treatment at wastewater treatment plants and does go unaccounted for. The problem of unaccounted wastewater does pose a threat to contamination of environment. Wastewater can be lost through pipe leaks, malfunctioning distribution systems or losses from accounting errors. But the primary cause for excessive unaccounted for wastewater is often pipe leaks.
There are different types of wastewater leaks. These include service line leaks and valve leaks. However, in most cases, largest portion of wastewater is lost through leaks in the mains. There are many causes of leaks and in many cases a combination of factors lead to its occurrence. Factors that lead to leaks include the material, age, composition, and joining methods of the wastewater systems. Another related factor is the quality of the initial installation of wastewater treatment system components.
Leaks are not just an infrastructural issue. Sometimes even wastewater conditions like temperature, aggressiveness and pressure are also a factor. External conditions, such as stray electric current, contact with other structures, and stress from traffic vibrations, frost loads, and freezing soil around a pipe can also contribute to leaks. Thus for efficient wastewater leak detection it is important for wastewater treatment plants to have a effective water accounting system, leak repair and pipe replacement. This will help in tracking wastewater throughout the wastewater treatment system thus identifying areas that may need attention, particularly if large volumes of wastewater are lost.
What is Leak Detection?
There are various methods for water detection in water distribution system leaks. These methods generally involve using sonic lead detection equipments that identify the sound of water escaping a pipe. These devices can include accurate listening devices that make contact with hydrants and valves, and geophones that listen straight on the ground. In addition, correlate devices can listen at two points simultaneously to find the exact location of a leak.
Note that large leaks do not essentially contribute to a greater volume of water that is lost as they are usually detected quickly, isolated and repaired. However, it is the undetected leaks that lead to large quantities of wastewater lost, as these pipe leaks might exist for long period of time. Ironically small leaks are easier to detect because they are noisier and easier to hear using hydrophones. The most difficult pipe leaks to detect and repair are usually those under stream crossings.
Leak detection efforts should ideally be focused on the part of the wastewater treatment system, which has the greatest expected problems. These include areas:
- Which have a history of excessive pipe leak and break rates
- Where leaks and breaks can result in the heaviest property damage
- Where system pressure is high
- Which are exposed to lose electric current and traffic vibration
- Where load on pipe exceeds the design load
Leak Repair & Pipe Replacement
Leak detection is only the initial step in eliminating leakages, leak repair and pipe replacement. In this process, leak repair is the most costly step. Preferred methods for repairing small leaks is repair clamps or collars, whereas larger leaks may require replacing one or more sections of pipe. However, some argue that instead of repairing the leaking mains it is preferable to undertake pipe replacement for pipes that are old and more prone to leakages. Thus selecting a repair strategy will depend upon the frequency of leaks in a given pipe and the relative costs for leak repair and pipe replacement.
Deciding whether to emphasize on leak detection and leak repair over pipe replacement will depend on site-specific leakage rates and costs. Generally leak detection and leak repair result in an immediate reduction in contamination by wastewater. Whereas, pipe replacement will have a long term impact to the extent that it eliminates the root cause of pipe leaks. However, the most important factor in a leak detection and leak repair system is the requirement for accurate and detailed data. This data needs to be consistent over time and should be easy to evaluate and will help you analyze if wastewater is lost through leakage. Thus the three sets of records that should be maintained are:
- Monthly reports on wastewater that is send for water treatment
- Leak repair and pipe replacement report forms
- Updated maps of the wastewater collection system that shows the location, type and class of each pipe leak.
Coordinating Leak Detection, Leak Repair & Pipe Replacement with Other Activities
To save cost and time involved in leak repair and pipe replacement, the leak detection and repair program can also include inspecting and rehabilitation of other water utility functions. These include:
- Inspecting hydrants and valves in a water distribution system
- Updating maps of wastewater collection system
- Installing and using remote sensor and telemetry technologies in order to continuously monitor and analysis source, transmission, and distribution facilities. Remote sensors and monitoring software are usually installed to alert operators of any leaks, fluctuations in pressure, problems with equipment functions and various other concerns
- Inspecting pipes, cleaning, lining, and other maintenance efforts to improve the distribution system and prevent leaks and ruptures from occurring.
Based on the above, one can understand that pipe leaks can cause high quantity of water wastage. Therefore, efficient leak detection, leak repair and pipe replacement has become the need of the hour.
