The rapid growth of urban areas in India has reached a level never before seen. As pressure from increasing numbers of people has caused more demand for quality drinking water supplies and existing pipe networks begin to age, distribution efficiency has become a major focus for municipal authorities across the country.

The ability to minimize water waste while improving reliable service delivery will require municipal authorities to construct resilient pipelines over the next few years to continue supporting future growth.

In this regard, medium-density polyethylene (MDPE) pipe products represent a proven, affordable solution for water management in large urban centres. Due to their flexibility, strength, and ability to resist leakage, MDPE pipes are ideal for India’s high-density, complex, urban environments.

Growing Urban Water Challenges in Indian Cities

The various structural and operational difficulties faced by Indian cities when it comes to their water supply systems include:

Rapid Urbanization

• Urbanization has been increasing the demand for water every day due to a growing population living in cities.

• Informal settlements usually do not have enough pipelines to adequately provide the required water to their inhabitants.
• The high density of many of these projects makes it difficult for workers to access the pipelines for repairs and/or upgrades.

Aging Infrastructure

• Many cities still make use of existing metal or concrete pipe systems that are very old.
• These older pipes tend to have issues such as corrosion, scaling and joint failure that create regular leaks.
• When a pipe bursts, it not only creates a water supply disruption, but also causes damage to the pavement or road surface.

Non-Revenue Water (NRW)

NRW refers to water that is lost prior to reaching the consumer due to leakage, theft, or incorrect meter readings. In many Indian cities, the NRW rates approach 30-40%, and this greatly reduces water availability and revenue.

Ground Conditions & Traffic Load

• Water pipelines in urban areas are subjected to heavy loads from vehicles moving above them.
• Soil movement and settling of the ground create significant stress on rigid gas distribution pipes.
• Roads are being excavated frequently for repairs, increasing the potential for damage to pipes during these excavations.

In order to develop solutions for these problems, new materials that possess the characteristics of flexibility, corrosion resistance, ease of installation, and long service life will be needed. The pipes that have the best qualities of these requirements are MDPE pipes.

What Makes MDPE Pipes Ideal for Urban Water Supply Systems

Municipal water distribution networks throughout India are increasingly turning to MDPE pipe because of its exceptionally high-performing characteristics described below.

What Are the Benefits of MDPE Pipes?

• Adaptability to ground movement by being highly flexible
• Break resistance
• Corrosion and chemical resistance
• Smooth interior surface for better flow
• Lightweight and easy to install

Unlike metal pipes, MDPE is not subject to rust or scaling due to the chemical properties found in water. Therefore, MDPE pipe ensures constant water quality and reliability over time.

Technical Benefits of MDPE Pipe:

• High tensile strength for underground use.
• High resistance to cracking due to loads placed on the pipe.
• Compatible with both electro-fusion and compression fittings.
• Can be used for potable water.

MDPE pipe is very effective for service connections, distribution mains, and urban extensions of water supplies.

Role of MDPE Pipes in Reducing Water Loss and Non-Revenue Water

One of the top priorities for urban utilities is to decrease water loss.

How MDPE contributes to decreasing Non-Revenue Water (NRW):

• Leak-free fusion joint connections eliminate water seeping through pipe walls.
• The smooth surfaces of the interiors of pipes minimize friction and pressure losses.
• The high resistance of MDPE pipe to cracking helps reduce burst incidents.
• MDPE has a long lifespan, providing for fewer cycles of repair.

Water lost through underground leaks is not just a waste of valuable resources, but it also adds to operational costs. Municipal planners can drastically cut their leakage rates through the installation of MDPE distribution systems.

MDPE pipes provide more efficient hydraulic performance:

• Smooth internal pipe surfaces reduce the buildup of scale.
• The internal diameter of MDPE pipes is relatively constant.
• Aids in improving the piping efficiency of flow.
• Requires less energy for pumping.

The use of less energy for pumping will lower costs and be more environmentally sustainable.

Cost-Effective Installation and Maintenance Benefits of MDPE

Cost-effectiveness is vital for urban projects. This is true of both materials costs and total life value.

1. Cost-Effective Installation

• Using lightweight piping reduces transportation costs.
• Simplified handling decreases man-hour requirements.
• Quick installation reduces road closure times.
• Preformed coils reduce the need for multiple joints. 

2. Low Maintenance Needs

• MDPE pipes are less likely to need repairs than traditional materials.
• Hold up to corrosion.
• Experience fewer joint failures.
• Sustain less cracking under load.

3. Extended Life Expectancy

With proper installation, an MDPE piping system can deliver up to 40-50 years or more of service and result in the overall cost-effectiveness of the long term.

goflo offers high-quality MDPE pipes for the distribution of potable water. Our MDPE products meet Indian standards and are designed with durability, pressure capability, and long-term performance in urban water systems as the primary requirements. 

MDPE Solutions Supporting Smart Cities and Sustainable Infrastructure

India’s Smart Cities Mission promotes the creation of sustainable infrastructure with the provision of efficient services, and limits environmental damage, which aligns well with the characteristics of MDPE pipe.

Some of the sustainability advantages of using MDPE pipe include:

• Significant reduction in water loss helps conserve precious resources.
• The energy required for pumping is significantly less than that of traditional systems.
• Can be recycled as a material.
• The projected operational life of MDPE pipe results in less waste due to replacements.
