Hainan Municipal Pipeline

The water supply pipeline project aims to provide safe and clean tap water supply for urban residents. Water supply pipeline engineering involves water source collection, water treatment, design, construction and maintenance of water transmission pipeline system, etc.

The water supply pipeline project is generally composed of water transmission pipeline and water distribution pipeline. The water transmission pipeline usually adopts two parallel lines, which are used between the water source and the water plant, or directly connected to the water distribution pipeline. The distance is long, the pipe diameter is large, and the flow is large. The water distribution pipe is to branch the water transmission pipe and then branch to each household. The distance is short, and the flow and diameter are small.

The following is the general process of water supply pipeline works:

● Water source collection: the first step of the water supply pipeline project is to determine a reliable water source. This can be groundwater, rivers, lakes or reservoirs. The selection of water source shall consider the feasibility of water quality, water quantity and sustainable supply.

● Water treatment: the collected water source needs to be treated to ensure that it meets the standard of safe drinking water. Water treatment process usually includes purification, disinfection, removal of suspended solids and impurities and other steps to ensure clean water quality.

● Design of water transmission pipeline system: design the layout of water supply pipeline system according to the scale and demand of the city. This includes determining the location of main pipeline, branch pipeline, water distribution network, water tank, well and other facilities.

● Pipeline laying: according to the design scheme, the water supply pipeline shall be laid. This includes excavation of trenches, installation of pipes, connection of pipe fittings, pressure test and disinfection of pipes, etc.

● Equipment installation: install necessary equipment in the pipeline system, such as pump station, water pump, water meter, etc. These devices are used to regulate water pressure, measure water volume and monitor the operation of the water supply system.

● Operation and maintenance: once the water supply pipeline system is completed, it needs to be operated and maintained. This includes regular patrol inspection, pipeline cleaning, repair of damaged parts, equipment renewal, etc., to ensure the normal operation of the pipeline system and water quality safety.

The design and construction of water supply pipeline project need to consider many factors, including water source protection, water quality monitoring, water supply pressure control, system reliability and emergency response. These measures are aimed at ensuring that residents have access to high-quality tap water supply to meet their daily life and production needs.
