Promoting piped drinking water is a vital public welfare project that aligns with contemporary demands and concerns the well-being of citizens. Its significance spans multiple critical dimensions including health protection, economic optimization, social sustainability, and urban development, which can be summarized as follows:
I. Health Protection: Addressing traditional drinking water safety hazards by providing high-quality direct drinking water
The core value of piped drinking water lies in achieving end-to-end safety control from source to tap, fundamentally resolving the pain points of traditional drinking water methods.
      • Removes harmful substances: Utilizes advanced treatment processes like ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO) to effectively eliminate bacteria, viruses, heavy metals (e.g., mercury, arsenic, lead), and organic contaminants (e.g., pesticide residues, industrial solvents) from tap water (or water meeting potable standards).
      • Prevents Secondary Contamination: Replaces aging, corroded traditional water pipes with an independent, sealed food-grade stainless steel (e.g., 304 stainless steel) circulation network. A 24-hour water circulation mechanism ensures fresh water quality within the network, eliminating bacterial growth in stagnant water.
      • Consistently compliant water quality: Strict adherence to the “Drinking Water Quality Standard” (CJ 94-2005), which imposes stricter requirements than standard tap water for parameters including turbidity (≤0.5 NTU), total coliform bacteria (not detectable), residual chlorine (0.05-0.3mg/L). Real-time monitoring via online water quality equipment ensures terminal water consistently meets direct drinking standards.
II. Economic Optimization: Reducing Long-Term Water Costs, Enhancing Cost-Effectiveness
Pipe-direct drinking water adopts centralized treatment and large-scale operation models, significantly lowering per capita usage costs. Over the long term, it proves more economical than traditional drinking water methods.
      • Compared to bottled/barrel water: Barrel water costs approximately 1-2 RMB/liter (550ml bottled water costs about 2-3 RMB), while piped drinking water costs only 0.2-0.3 RMB/liter—equivalent to 1/5 to 1/6 the price of barrel water. For a family of three, annual costs for piped drinking water (around 300-500 RMB) are substantially lower than purchasing bottled water (around 800-1500 RMB) or using a home water purifier (filter replacement + machine cost approx. 1000-2000 RMB/year).
       • Reduced hidden costs: Eliminates time and labor costs associated with ordering, delivering, and replacing bottled water, as well as the hassle of regularly replacing filters in home water purifiers, delivering instant-on convenience.
III. Social Sustainability: Promoting “Plastic Reduction and Carbon Reduction” to Support Ecological Civilization
The promotion of piped drinking water serves as an effective measure to combat “white pollution” and achieve “dual carbon” goals.
      • Reduce plastic usage: Statistics show that producing 1 liter of bottled water consumes approximately 0.3 liters of petroleum, with roughly 8 million tons of plastic bottles entering oceans globally each year. Replacing bottled/barrel water with piped drinking water significantly reduces plastic packaging and mitigates the environmental impact of “white pollution.”
      • Conserving Water Resources: The “separate supply” model of piped drinking water (distinguishing drinking water from domestic water) prevents wasteful practices like using high-quality water for low-value purposes (e.g., flushing toilets or washing cars). Additionally, the water recovery rates of nanofiltration and ultrafiltration processes (approximately 70%-90%) exceed those of reverse osmosis (around 50%), making them more water-efficient.
IV. Urban Development: Enhancing Livelihoods and Strengthening City Competitiveness
Pipe-delivered drinking water is a vital component of new urban infrastructure, aligning with the strategic goals of “Healthy China” and “Beautiful China” while driving multiple aspects of urban development.
      • Meeting High-Quality Public Demands: As living standards rise, residents' expectations for drinking water have evolved from “safety” to “health and convenience.” Pipe-delivered drinking water enables “healthy water straight from the tap,” enhancing residents' sense of well-being and embodying the spirit of “people-oriented projects.”
      • Elevating Urban Image: Pipe-delivered drinking water stands as a hallmark of urban modernization, reflecting government commitment to public welfare. For instance, Shenzhen aims for citywide coverage by 2025, while Shanghai has incorporated “household drinking water access” into urban planning—measures that bolster a city's appeal and competitiveness.
      • Driving Industrial Development: The expansion of piped drinking water stimulates growth in related sectors such as water purification equipment manufacturing, smart pipeline systems, and operational maintenance services, creating new economic growth points. Companies like Angel Water have participated in R&D for piped drinking water technology, with their products deployed in major projects like the National Stadium and Daxing Airport, propelling industrial upgrading.
V. Policy Support: Aligned with National and Local Development Directions
The promotion of piped drinking water is not a “spontaneous initiative” but a clear requirement of national policies and local planning.
      • National Strategy: The “Healthy China” strategy (2019 State Council “Opinions on Implementing the Healthy China Initiative”) emphasizes “ensuring drinking water safety”; The 14th Five-Year Plan outlines “advancing new urban development to build livable, innovative, smart, green, people-oriented, and resilient cities,” positioning piped drinking water as a key component of “new urban infrastructure.”
      • Local Policies: Multiple provinces (e.g., Hunan, Henan, Jiangxi) have issued notices promoting piped drinking water construction and retrofitting, mandating “mandatory installation of drinking water facilities in new residential buildings” and “incorporating piped drinking water into old residential area renovations.” For instance, Hunan Province issued the “Notice on Advancing the Construction and Renovation of Urban Piped Direct Drinking Water Systems” in 2022, clarifying the principle of “government guidance, enterprise operation, and user voluntarism” to promote the widespread adoption of piped direct drinking water.
Summary
The significance of promoting piped direct drinking water fundamentally lies in its embodiment of the “people-centered” development philosophy. It addresses the “safety hazards” and “high costs” associated with traditional drinking water methods while advancing ecological civilization through “plastic reduction and carbon emission cuts.” Simultaneously, it elevates urban modernization and competitiveness. With technological advancements and policy support, piped drinking water is poised to become the “standard configuration” for future urban water supply, delivering healthier, more convenient, and sustainable drinking experiences for residents.
