On September 27, the Donghu Water Plant, as the first water plant in Shenzhen, the capacity expansion and renovation project of Donghu Water Plant was officially launched. As the first direct-drinking demonstration smart water plant with advanced treatment technology to be built in Luohu District, the reconstruction of the project is of great significance for improving the safety and security of regional water supply and accelerating the promotion of tap water in Shenzhen.

Donghu Water Plant is located at No. 4002 Aiguo Road, Luohu District, adjacent to Shenzhen Reservoir in the east. It covers an area of 45,000 square meters. It was built in 1961 and was the first water plant to be constructed in Shenzhen. After the expansion, the current water supply scale of 350,000 m3/d will be formed. The main service area is Luohu District (except Liantang Street). There are four DN1000 factory pipes, three of which are in the direction of Aiguo Road and one in the direction of Buxin Road.

The scale of the expansion and renovation project of the East Lake Water Plant is 600,000 m3/d, with a total investment of 2.024 billion yuan. It is constructed by Shenzhen Environmental Water Affairs Group, designed by Shanghai Municipal General Research Institute, and undertaken by Special Zone Construction Engineering Group. Including the newly built 600,000 m3/d water intake and water intake pipe, conventional treatment and advanced treatment technology, and simultaneous construction of sludge treatment facilities of the same scale. After the renovation, it covers an area of 56,000 square meters and is expected to be completed by the end of 2024. The municipal headquarters of the Special Zone Construction Engineering Group is the lead unit of the project EPC general contractor.

The expansion and renovation project of the East Lake Water Plant is a major livelihood project at the city and district levels. As the first direct drinking demonstration smart water plant with advanced treatment technology in Luohu District, Donghu Water Plant is of great significance for improving regional water supply security capabilities and accelerating the promotion of tap water in Shenzhen.

The East Lake Water Plant will be constructed according to the high standards of the Zhan Tianyou Award, and will be built into a new era modern smart water plant with advanced concepts, highly intensive, green and low-carbon, natural and efficient, and smart empowerment. The transformation of "" has become a "exquisite project, demonstration project, and name card project" in the water industry, providing deep water protection for the city's direct drinking in 2025, drawing a new chapter for the water supply industry in Shenzhen in the new era, and setting a demonstration for the national modern drinking water plant.

Forward policy first-the deep water origin, born towards the new

As the first water plant in Shenzhen, Donghu Water Plant is the origin of Shenzhen's water business and the starting point for innovative water supply models. In the planning and construction, Shenzhen Environmental Water Affairs Group first introduced advanced services before the construction of the project, creatively proposed the project positioning of "deep water origin, new birth", and condensed the formation of the image symbol of "East Lake 1961" and the design element of "circle" , Running through the architecture, landscape, and detail design of the factory area, creating a water culture of “six gardens and nine sceneries” in space, making Donghu Water Plant a city water culture with history, story, technology, and connotation public space.

Process innovation-pool body overlap, intensive and efficient　

Faced with the reality that the land use index is only 36% of the underground limit for the construction of the national water supply project, the Donghu Water Plant determined the process plan for the pool body superimposition, through the combination of pre-ozone pools, advanced treatment comprehensive pools, and sludge treatment comprehensive pools. Realize the national optimization of land use indicators and build the first highly intensive water plant in China. At the same time, the advanced treatment process of "ozone + upward flow biological activated carbon" is added, the water quality of the factory will be greatly improved, and the taste of direct drinking will be significantly improved.

Construction innovation-combination of demolition and construction, safety guarantee

Donghu Water Plant is the main water plant in Luohu District, and it is responsible for the safety of water supply. Faced with the dual difficulties of land shortage, not affecting residential water use, and water quality of the Shenzhen Reservoir, the reform idea of "demolition of single construction process" and the construction steps of "demolition first, then construction, step-by-step" were put forward to ensure the need during the expansion and reconstruction period. Guaranteed 300,000 m3/day water supply scale.

Green innovation-energy saving and emission reduction, low carbon and environmental protection　

The Donghu Water Plant implements the concept of green and low-carbon. It saves energy and reduces emissions by carefully optimizing the pipeline direction and vertical layout, carefully analyzing the operating hydraulic conditions of the system under different working conditions, and scientifically optimizing the selection of important equipment for super-large pumping stations. Reduce operating costs.

Technological innovation-BIM application, smart creation

Donghu Water Plant adopts BIM and digital twin technology to create multiple intelligent systems covering production, equipment and facilities, safety control, integrated operation, project management, etc., forming a digital full life cycle management from design, construction to operation, and will become the future "unmanned "On duty, few people on duty" smart water plant template.
