Construction survey is an extremely important technical work that runs through the entire process of engineering project construction, and can be called the “GPS” of the specific construction project implementation. In the mean time, engineering survey skills are the necessary job capabilities for first-line construction engineers. During the construction process of building project, surveying and setting out is the first and the essential procedure and also a key process to ensure the quality and design intention of the entire project. With the rapid development of social science and technology, measuring instruments and new technologies are constantly being updated. Survey technicians must not only be proficient in the usage of conventional traditional survey tools, but also need to continuously learn to use new measuring instruments, technologies and new measuring methods in order to complete the work they are facing. In practice, surveying and setting-out is a comprehensive technology that uses solid geometry, plane geometry, analytical geometry and other knowledge combined with multiple skills. Survey technicians do need to continuously learn and summarize to fully digest the knowledge and skills, and to increase the efficiency of construction projects.

Water is the basic element for human survival and the basic guarantee of social and economic development. The problem of drinking water pollution is diverse and complex. To provide safe and high-quality drinking water, water supply enterprises must take appropriate safety measures agaist the entire water supply system, from water sources,
water plants, pipe networks to faucets, and seek systematic technical solutions. The densely placed underground pipe network and secondary water supply system, though located near the end of the water supply system, are the key and weak links for the safe water supply, and also the difficult points in the study of drinking water safety.

    At present, the water quality of urban water supply in our country is generally good when the water is discharged from water plants, but water quality declines, to varying degrees, after entering the water distribution network. This is especially true for China’s current water supply system which uses surface water as the main raw water. Due to water source pollution, the addition of various agents (oxidants, coagulants, disinfectants) in the water purification process, and the technical limitations of the traditional water purification process itself, when the so-called "purified water" enters the water distribution pipe network, it reacted with pipe interior surface during its long time transportation. Many complex physical, chemical and biological interactions occur in this process produce physical deposition, electrochemical corrosion, biofilm growth, biological corrosion and the growth of animalcules etc. At the same time, various corrosion products and microorganisms interact with various disinfectants added to the water, various metal salts and xenobiotic pollutants brought into the factory water during water purification process,causing the water quality of the pipe network to go bad. Various water quality issues concerning water supply network have attracted the attention of relevant experts and industry players. The water quality issue of the water supply network will be a great challenge to water supply industry around the world in 21st century. Water quality assurance technology about water supply network has become a research focus. Research on safe drinking water distribution technology is of great significance for water plants to keep water purification effect and ensure the safety of drinking water at the end of the pipe network.
