Recently, after months of construction, the lighting renovation project of the sewage treatment plant organized and implemented by Jiaxing United Sewage Company of Zhejiang Province has been fully completed and put into operation. Brand-new LED lamps illuminate every key area of the plant, injecting new vitality into the "water purification heart" that safeguards Jiaxing’s water environment.

With the core objectives of improving on-site operation safety, promoting energy conservation and consumption reduction, and realizing intelligent management and control, the renovation has successfully upgraded the lighting system while the plant maintains 24-hour uninterrupted operation. The new system adopts high-efficiency and energy-saving LED lamps integrated with intelligent control technology to realize "on-demand lighting", which significantly improves lighting conditions in the working environment, effectively enhances night inspection efficiency and operational safety, and provides solid support for the stable operation of the urban sewage treatment system.

This renovation was not just a simple "lamp replacement". The project faced multiple challenges, including complex underground pipelines, simultaneous production and construction, and scattered working areas. The project team planned in advance and formulated a zoning, phased and off-peak construction scheme to avoid production peak hours. During construction, engineers strictly implemented safety disclosure and pipeline protection measures, combining manual exploration and mechanical avoidance to ensure "zero damage" to underground pipelines and "zero interference" to production. Meanwhile, the Engineering Department of the company strictly controlled quality, carried out joint acceptance of various equipment and materials, and tracked concealed works throughout the process, ensuring project quality from the source and promoting the successful conclusion of the renovation.

"Intelligence + Green" is the core highlight of this renovation. Based on the actual conditions of the plant, Jiaxing United Sewage Company has elaborately built a refined lighting management mode. In view of the plant’s special environment featuring humidity, corrosion and explosion-proof requirements, LED lamps with appropriate protection grades are selected for different zones, balancing lighting effect and operational safety.

In terms of energy conservation, solar street lamps are installed on main roads, which store energy during the day and supply power independently at night, greatly reducing the load on the power grid. Intelligent time-control systems are adopted in working areas and inspection passages to automatically switch lamps on and off, eliminating power waste. In addition, the intelligent system is equipped with remote monitoring and fault alarm functions, which not only reduces operation costs but also improves the safety and efficiency of night inspections.
