Water Supply and Drainage Installation Engineering Specialty Classification:
Water Supply Engineering
Water Supply Engineering for the residents and factories, mines, transportation enterprises to supply water for living, production of water supply projects as well as fire-fighting water, water, road landscaping and so on. By the water supply source, water structures, raw water pipelines, water treatment plants and water supply network consists of a collection and delivery of raw water, improve water quality. ① water sources are surface water, groundwater and reuse. ② water intake structures have surface water intake structures and groundwater intake.
Drainage engineering
Drainage engineering to exclude human sewage and production of a variety of wastewater, excess surface water project. It consists of a drainage system (or trench), a wastewater treatment plant and a final treatment facility. Usually also includes pumping facilities (such as drainage pumping stations) .
① Drainage pipe system is a network of pipes that collects and transports wastewater (sewage), and there are combined pipe systems and diversion pipe systems. ② wastewater treatment plant including sedimentation tanks, sedimentation tanks, aeration tanks, biofilters, clarifiers and other facilities and pumping stations, laboratories, sludge dewatering machine rooms, repair plants and other buildings, wastewater treatment of the general objective is to remove suspended solids and improve oxygen consumption, and sometimes disinfection and further treatment.
3 final treatment facilities. Depending on the different drainage objects with pumps or other water lifting machinery, will be treated by the treatment plant to meet the specified discharge requirements of the wastewater, discharged into a water body or discharged on the land.
Fire protection works
Fire protection works include fire protection system works of cities and buildings. It includes fire hydrant systems, automatic sprinkler systems, water spray systems, water curtain fire extinguishing systems, fire water cannon systems, and rain shower systems.
