The water supply and drainage system is a system that provides users with the type, volume and quality of water to meet different needs, and at the same time undertakes the collection, transportation and treatment of users' wastewater to remove pollutants in wastewater for human health and environmental protection.
The water supply and drainage system includes the water supply system, wastewater drainage system, rainwater drainage and then collects all types of domestic water, wastewater from the sub-pipe systems in the project for construction, regulation, distribution and then transports through the drainage network system to the septic tank and discharges outside.
2. Construction measures for water supply and drainage in civil construction
In the project, water supply equipment such as pumps, valves, pipes, etc. used must comply with the design requirements in terms of type, quality and origin. Water pipes and equipment must be installed in the correct position and in accordance with the design regulations. In addition, the joints must be secure and tight, and after installation, measures must be taken to protect the pipes and equipment from being crushed, distorted or damaged.

During construction, plumbers must coordinate with bricklayers and formwork workers to arrange pipes, water supply and drainage pipes through beams, floors and walls according to the previous design drawings. Construction pipes must be carefully preserved to avoid sand, soil, etc. falling into the pipes during the construction process.
Pipe threads and pipe joints must ensure tightness to avoid leakage. Underground water pipes must be installed before the bricklayer plasters the walls.
After installation is completed, the contractor must conduct a pressure test for each pipeline and according to the specific usage requirements of the pipeline according to the design. Pressure testing equipment includes an electric pressure pump, a pressure gauge with a measurement index of 0 - 20 kg/cm2, and an air release valve.
During the testing process, the pipe must be filled with water slowly; and carefully so that all air escapes; the pipe must be filled with water; within 24 hours before conducting the pressure test; test pressure and test time must comply with design regulations and investor instructions.
3. Some notes when carrying out water supply and drainage construction measures
To ensure the quality and technical construction of water supply and drainage; you need to ensure the wastewater drainage system; should not use complicated connections such as "T" and "X" connections. These connections make wastewater easy to stagnate and become clogged.
Wastewater systems and drainage pipes need to be equipped with inspection doors. This is a way to help clear the entire system. Depending on whether the main drainage pipe is horizontal or vertical; the inspection door is arranged directly at the water trap or at the bottom of the pipe. However, the inspection door must be easily accessible.
In addition, sanitary equipment must be equipped with odor-preventing water traps. Manholes, septic tanks or wastewater tanks; must also be watertight, airtight and ventilated. Horizontal wastewater pipes must have a slope in the direction of flow; a suitable way to push both liquid and solid waste out.
