Access to clean and safe drinking water is fundamental for maintaining human health and enhancing well-being. Borewells are commonly utilized by households, particularly in rural regions, to tap into groundwater for daily requirements. Establishing appropriate borewell infrastructure is vital for sustainable water extraction while preventing contamination. This is where UPVC pipes, or unplasticized polyvinyl chloride pipes, outperform the traditionally utilized galvanized iron (GI) pipes in borewell casing and water lifting operations.

UPVC pipes offer numerous benefits, making them the favored option for constructing new borewells and upgrading outdated GI pipelines.
Exceptional Resistance to Chemicals and Corrosion
The primary benefit of UPVC pipes originates from their remarkable resistance to chemicals. UPVC is composed of carbon and chlorine, ensuring a stable, inert nature against multiple chemicals and compounds.
In comparison, GI pipes contain iron, rendering them susceptible to rust and corrosion, especially when conducting water. A study by the Water Research Foundation noted that nearly 59% of water supply pipes in the US remain made from corrosion-vulnerable materials such as GI. This can lead to the undesirable leaching of metals like iron, manganese, and lead into the water supply, making it unsafe for consumption.
Conversely, UPVC pipes exhibit complete corrosion resistance, with studies reporting negligible corrosion even after more than ten years of exposure to aggressive chemicals. This remarkable chemical stability guarantees the maintenance of water purity through UPVC borewell systems without metal contamination, even after decades of use.
The Indian Plumbing Association recommends that households switch from aging GI pipes to modern, non-reactive UPVC tubes to avoid water quality problems. Choosing UPVC during the initial phase of construction mitigates future replacement costs due to corrosion. Typically, GI systems require replacement within 8-10 years due to degradation, while UPVC can function effectively for 15-20 years.
Reduced Maintenance Needs
UPVC's corrosion resistance translates to substantially lower maintenance needs than metal piping. Regular maintenance is required for borewell systems to ensure they function properly and the water quality remains intact. GI pipes are more vulnerable to issues like corrosion, rust, mineral buildup, and biological growth.
A DHI study determined that corrosion shortens the life expectancy of GI pipes to merely 12-15 years, necessitating replacement sooner than UPVC, which boasts a service life exceeding 50 years, accompanied by consistent optimal flow and minimal energy pumping requirements. The lack of rusting and buildup ensures reduced operating costs, which can be over 75% lower with UPVC pipelines compared to their metal counterparts. Utilizing quality UPVC pipes that meet BIS and NSF standards ensures long-lasting performance with minimal repairs or replacements.
Enhanced Hydraulic Performance
The friction coefficient is crucial for understanding hydraulic efficiency in piping materials. It dictates how readily water moves through the pipelines. Metallic materials, including steel or GI, possess higher friction coefficients relative to smoother plastics like UPVC and polyethylene.
Research by the American Water Works Association has demonstrated that when transitioning from 150 mm GI pipes to 125 mm UPVC counterparts, there's a reduction in pumping electricity consumption of over 20%. This directly boosts hydraulic efficiency and reduces operating expenses for borewell systems constructed from UPVC.
Additionally, metallic pipes tend to decrease in diameter as corrosion advances over time, necessitating increased pumping pressures for adequate water flow. Conversely, UPVC maintains a consistent performance level throughout its usable lifespan.
A 20-year financial analysis on UPVC compared to GI pipelines reveals about 40% less expenditure on the former, primarily due to reduced maintenance, absence of corrosion, and lowered pumping expenditures.
Simple and Efficient Jointing
Metal piping systems generally rely on threaded connections, which necessitate skilled labor and equipment for installation, leading to potential leaks from improperly sealed threads.
In contrast, UPVC pipes utilize solvent cement welding to form robust, leak-proof joints in mere minutes, simplifying the installation process and minimizing the risk of leaks. Solvent cement joints also offer mechanical strength comparable to the pipes themselves, withstanding substantial tensile loads without failure. Consequently, this enables quicker and more secure installations, further adding to the reliability of UPVC systems.
Minimal Environmental Impact
In terms of sustainability, UPVC pipes emerge as a superior choice. The production of GI and other metal pipes generates significantly higher CO2 emissions, estimated to be five to eight times more than that of UPVC manufacturing. Additionally, the usage of recycled plastics in UPVC contributes to a substantial reduction in its carbon footprint, by more than 20%.
A lifecycle analysis indicates that UPVC pipes boast the least environmental impact among common materials used in water transport, making them a sustainable option.
Simplified Installation and Handling
When it comes to practical considerations for installation, UPVC pipes offer clear advantages over their metallic counterparts. Weighing significantly less—up to 75% lighter—UPVC pipes are easier to transport and handle, thereby minimizing risks during loading, unloading, and laying operations.
Moreover, UPVC can be supplied in longer lengths (6 or 12 meters) as opposed to the standard 6-meter GI pipes, allowing fewer joints, reducing the complexity of the installation process within borewell shafts.
Maintaining Water Purity
One of the key reasons for establishing borewells is to ensure a consistent supply of potable water. As previously noted, UPVC pipes are entirely inert, minimizing the risk of chemical interactions or leaching of contaminants.
Multiple studies have shown that water samples from UPVC systems reflect minimal traces of various volatile organic compounds, adhering to WHO and BIS safety limits. In stark contrast, water supplied through GI pipes often contains elevated levels of harmful metals due to corrosion, making it unsafe for consumption and necessitating additional purification steps.
Mitigating Contamination Risks
With borewell systems, there exists a constant risk of external contaminants infiltrating through damaged casings or pipes. Furthermore, the chemical composition of GI pipes increases the chance of microbial-induced corrosion, allowing pollutants such as heavy metals and organic materials to mix with the extracted water.
This scenario has been linked with various health issues, highlighting the importance of utilizing UPVC pipes, which prevent contaminant ingress and maintain the integrity of the water supply over time.
Resilience to Harsh Underground Conditions
Considering the challenging subterranean environment, UPVC pipes are engineered for exceptional performance. Utilizing specialized materials like titanium dioxide and antioxidants enhances their resistance to heat, chemicals, and mechanical strain, ensuring longevity despite adverse conditions. UPVC pipes maintain over 85% of their strength and visual quality after exposure to harsh underground settings.
Reliability in Diverse Climates
UPVC pipes are also capable of withstanding extreme temperature variations, proving effective in regions experiencing shifts from hot summers to freezing winters. With operating temperature resistance between -10°C and 60°C, their performance remains stable under various climatic conditions, making them suitable for borewell applications across the Indian landscape.
Cost Efficiency
Even with its superior characteristics, UPVC offers considerable cost advantages over traditional GI pipes. The price difference can be significant—typically 20-30% lower for UPVC compared to GI, leading to substantial savings over extended system lengths.
Additionally, lower maintenance needs and energy-efficient operation contribute to overall long-term financial savings exceeding 40% over a typical 20-year lifecycle.
Wide Availability across India
In recent years, improvements in domestic production and distribution networks—supported by initiatives like the Jal Jeevan Mission—have made UPVC pipes readily available across India. With major manufacturers ramping up production, these high-quality piping solutions can now be acquired in both urban and rural areas at competitive prices.
Conclusion
Ensuring the availability and quality of water is critical in the face of growing populations and environmental strains. Borewell systems provide a viable means to attain self-sufficiency, addressing local water needs sustainably.
