The development of water supply pipelines has seen several trends over the years. Here are some of the most notable ones:

1. Use of Plastic Pipes: In recent years, there has been a shift towards the use of plastic pipes, such as polyethylene (PE) and polyvinyl chloride (PVC), for water supply pipelines. These pipes are more durable, flexible, and resistant to corrosion than traditional metal pipes, and they are also easier to install and maintain.

2. Use of Composite Pipes: Another trend in water supply pipeline development is the use of composite pipes, which are made up of multiple layers of different materials. For example, some composite pipes are made up of an inner layer of plastic, a middle layer of aluminum, and an outer layer of plastic. These pipes offer the benefits of both plastic and metal pipes, such as durability and corrosion resistance, while also being lightweight and easy to install.

3. Implementation of Smart Technologies: Water supply pipelines are increasingly being equipped with smart technologies, such as sensors and monitoring systems, to improve efficiency and reduce waste. These technologies can detect leaks and other issues in real-time, allowing for faster repairs and preventing water loss.

4. Focus on Sustainability: There is a growing emphasis on sustainability in water supply pipeline development. This includes the use of environmentally-friendly materials, such as recycled plastics, as well as the incorporation of renewable energy sources, such as solar power, to operate pumping stations and other infrastructure.

5. Increased Collaboration: Finally, there is a trend towards increased collaboration between different stakeholders in the water supply pipeline industry, including government
