5 major projects involving 537 km of pipeline networks, with a total investment amount of nearly 400 million yuan

Thread Content

With the ongoing integration of urban and rural water supply systems, the renovation of old pipelines, and efforts to reduce water losses, investment in water supply infrastructure across the country is accelerating. Recently, regions such as Guangxi, Heilongjiang, Guizhou, and Yunnan have launched a series of water supply pipeline projects, with a total investment of nearly 400 million yuan and a total pipeline length of over 537 km. Comprehensive Overview of the 5 Major Projects: The Real Needs Behind 537 km of Pipeline Networks

1. Phase III of the Centralized Water Supply Project in Mashan County, Guangxi (approximately 98 million yuan)
Constructor: Mashan Subo Industrial Investment Co., Ltd.
Key components: Approximately 19 km of main pipelines from Guzhai to Jiafang; around 300 km of main and branch pipelines for water distribution in villages. Additional facilities include valve chambers, pressure reduction valves, and support pillars.
👉 Key valve requirements: A large number of gate valves/butterfly valves for the water distribution network; pressure reduction valves, vent valves, and sludge discharge valves; as well as small-diameter control valves at the village level.
👉 Estimated valve demand: Based on standard configurations for rural water supply, 8–12 valves per kilometer. Estimated total demand: around 2,500–3,500 valves.

2. Rural Water Supply Project in Hengshan District, Jixi City, Heilongjiang (12.08 million yuan)
Pipeline length: 82 km. Additional facilities include 1,303 water meters, 3 booster water plants, and 24 disinfection systems.
👉 Key valve requirements: For pump stations – check valves, gate valves, and control valves; for water plants – electric butterfly valves and control valves; for the pipeline network – mainly medium and small-diameter valves.
👉 Estimated valve demand: Total demand is approximately 600–1,000 valves.

3. Leak Reduction Project in Luodian County, Guizhou (approximately 58.98 million yuan)
Scope of work: Renovation of 3 pump stations, construction of a 1,000 m³ water tank, and renovation of approximately 24 km of pipelines with diameters ranging from DN100 to DN300.
👉 Key project concepts: “Leak reduction + precise control.”
👉 Upgraded valve configurations: High-sealing gate valves/ball valves, zone-specific metering valves, and pressure control valves.
👉 Estimated valve demand: Around 800–1,200 valves.

4. Pipeline Network Renovation Project in Guilong Area, Longli County, Guizhou (approximately 85 million yuan)
Pipeline scale: 35.3 km (with diameters from DN150 to DN600). Additional facilities include 4 booster pump stations, 155 secondary water supply units, and 253 pressure monitoring devices.
👉 Valve requirements by category: For main pipelines – large-diameter butterfly valves/soft-sealing gate valves; for the secondary water supply system – pressure reduction valves and pressure stabilizing valves; for intelligent systems – electric/remote-controlled valves.
👉 Estimated valve demand: Around 1,200–1,800 valves.

5. Water Supply Improvement Project in Shiping County, Yunnan (approximately 115 million yuan)
Key scale: 27.82 km of main pipelines, 44 km of branch pipelines, 13 km dedicated to leak reduction; water delivery pipes with a diameter of DN600.
👉 Key project concepts: “Renovation of old systems + smart water management.”
👉 Key valve requirements: Intelligent control valves, zone-specific metering valves, and highly reliable valves for main pipelines.
👉 Estimated valve demand: Around 1,500–2,500 valves
