Abstract:

Leak detection in transmission pipelines is crucially important for safe operation. Delay in detecting leaks leads to loss of property, roads and infrastructures. This research work is aimed to detect the leaks and evaluate their causes and effects. The results show that the leakages caused by; networks are small size pipes with high pressure, corrosion, damaged pipe joints, the rising water level in the city and tree roots. The ground subsidence and sinkholes spread in several streets in the city are the most common way to identify the leaks in the water and sewer networks. Pipeline leakage has both economic and environmental effects where the leaks cause many problems such as; health hazards a result of mixed groundwater with leaked wastewater. Loss of drinking water, soil erosion and ground subsidence. Also, leakages involve a significant economic loss reached 2 million Libyan dinars in the last 10 years. Most water and wastewater pipes are buried underground, making them difficult to find the location of leaks. So, using smart technologies such as; ground-penetrating radar, Acoustic systems, Sensor hoses, Fiber Optic Cable.. etc., are important to detect the leakages in the early stage.
