Drain mapping can also help identify severe blockages, leaks, and any other problem with the drainage system. This makes repair and replacement work much easier. Plumbers and drainage experts can save considerable time with drain mapping. It can also predict future problems and repair them in time to protect them from more damage and, therefore, higher repair cost.
Drain mapping can also be helpful in flood risk management as well as the prevention of pollution. Gaining a precise understanding of the underground drainage system can help experts in contingency planning in case of emergencies such as fire accidents, chemical spillages, and floods.
Drain mapping can be used for site compliance. Several commercial and public sites are required to comply with environmental and building regulations. Businesses can avail of these services periodically to identify any shortcomings and carry out remedial work in time to comply with these regulations
The simplest method of understanding the water flow is to check it at several stages throughout the route from entry to exit. This can be done by allowing the water to pour or run through the drain and inspecting the flow direction. This can be checked by opening a nearby manhole cover and seeing if the water is running through it. Another method is to flush a tissue paper in your toilet, lift the nearby manhole cover and follow where the tissue paper goes.
Water tests allow experts to check whether elements such as waste or sewage are present in the water or if the water is clear. This can help you identify the water flow and make it easier for you to access the entire network.
Similar to the water flow tracing method, dye tracing uses colour dyes for tracing water. The dyes are usually poured into the sink, toilet, and even directly into the drains. Specially designed dyes are used, usually available in the form of tablets, which are eco-friendly and do not damage the installation. They also do not leave stains on toilets, sinks, or drains.
CCTV drain surveys are the most comprehensive and advanced drain mapping method. The layouts and the locations of a drainage network can be easily identified using this method which involves lowering special CCTV cameras into the drainage system. The camera is then moved around the system, and video is recorded, which can help experts in countless ways. No excavation or digging is required as the cameras can reach all nooks and crannies.
Sonar drain tracing uses sound propagation to identify the location of pipes and other drainage installations under the ground. An active sonar system has a sound transmitter and a receiver. It creates pulses which are called ping. These pings detect echoes that can measure the distance between the sound source and the object. The electrical pulses can help identify specific features of the drainage network, which can further diagnose problems and issues.
Drain mapping is an essential service which should be availed when necessary, as we have mentioned above. Hire an experienced company which uses CCTV surveys to carry out drain mapping. This method is quicker, more affordable, and more precise. Whenever you carry out major construction work, make sure that your contractors are completely aware of the underground drainage system in that area to avoid legal troubles and save yourself from incurring losses. Remember, drainage and sewerage systems protect your property from several problems, including flooding, health issues, and infrastructure deterioration. Ignoring these systems to save any cost may make you lose more than what you were trying to save.
