Why carry out high-level secondary water supply equipment renovation?

2025/11/12??????view:
Why carry out secondary water supply equipment renovation for high-rise buildings?
1. Serious water pollution: Due to poor management and aging equipment, the water supply facilities in old residential areas are polluted by microorganisms, moss, small insects, and other factors, seriously affecting the health of residents.
2. Equipment aging and serious water leakage: Many water supply equipment in residential areas have a long service life, resulting in serious water leakage and high operating electricity consumption, leading to waste of water resources and increased electricity bills.
3. Non standardized management: Some property units do not attach importance to or regulate the management of secondary water supply facilities, lack long-term mechanisms, resulting in untimely maintenance of facilities and inability to guarantee water quality safety.

What are the benefits of renovating secondary water supply?
1. Improving water quality and pressure: The renovated water supply facilities adopt a fully sealed structure, which eliminates secondary pollution and ensures water quality safety. At the same time, the stability of water pressure is significantly improved, making it safer and more convenient for users to use water.
2. Energy saving and emission reduction: The new equipment operates automatically with variable frequency, saving 30-60% of electricity compared to the old equipment, reducing losses during water transportation, and lowering electricity costs.
3. Management standards: The renovated water supply facilities are managed and maintained by professional water supply enterprises, which improves management level and response speed, ensuring the continuous and stable operation of the water supply system.
4. User benefits: After the renovation, daily meter reading, charging, service, and maintenance will be the responsibility of the water supply enterprise, making it more convenient and efficient for users to use water, and the payment methods will be diversified, making it more convenient for residents to pay.

Specific measures and effects of secondary water supply renovation
1. Facility update: The renovation involves the cancellation of old water supply facilities and the construction of efficient and safe high standard facilities, including pump rooms, water tanks, control cabinets, etc.
2. Pipeline upgrade: Using durable and hygienic materials such as stainless steel water tanks and stainless steel pipes to ensure water quality safety.
3. Technological progress and equipment upgrades: With the development of water supply technology, secondary water supply equipment is constantly undergoing technological innovation and equipment upgrades. For example, a new type of water supply equipment that adopts digital microcomputer automatic control and high efficiency and low consumption, with a built-in PID controller, can automatically adjust the speed of water pumps and the start and stop of multiple water pumps according to the instantaneous pressure and flow changes in the pipeline network, ensuring that the water supply pressure is always constant at the preset value, while also having the characteristics of high efficiency and energy saving.

4. Intelligence and remote monitoring: Secondary water supply equipment is gradually developing towards intelligence, with the addition of data collection and remote transmission systems, security systems, remote monitoring systems, etc. in pump rooms to achieve remote monitoring and fault warning of equipment, improving the reliability and maintenance efficiency of equipment operation. For example, wired or wireless remote control of equipment can be achieved through GPRS/MODEM, enabling real-time control of the working status and pressure of each pump in different locations.
5. Water quality safety and maintenance management: During the renovation process, the original cement tank will be replaced with a food grade stainless steel water storage tank, and intelligent equipment will be installed to monitor water quality in real time. The water tank will be regularly cleaned to effectively improve the water quality of secondary water supply for high-rise residential buildings and ensure the safety of residents' water use. In addition, the renovated facilities will be professionally managed by the water supply company to ensure their long-term stable operation and maintenance.

Policy support and market demand: Provide policy support for the renovation of secondary water supply facilities to promote the smooth progress of the renovation work. For example, Jinan City plans to complete the complete renovation of secondary water supply facilities and user water meters in residential buildings within three years, and hand them over to water supply enterprises for professional management to solve water fee disputes caused by long-term water outages and pipeline leaks due to equipment damage. This policy support provides a broad market demand and development space for the renovation of secondary water supply equipment.
