Quenching a Thirsty Land: A Water Reservoir Project in Sundargarh, Odisha

May 13, 2024 | Case Studies

Picture this: Sundargarh, Odisha. A region grappling with water scarcity, facing the brunt of erratic rainfall patterns. But amidst the challenges, a glimmer of hope emerges. A new water reservoir project is underway, promising to transform the landscape and secure a sustainable water source for the community. This case study delves into the critical role our geosynthetics – Ocean HDPE Liner-1.5MM and Ocean NonWoven Geotextile-250GSM – played in bringing this vital project to life.

The Challenge: Securing Water, Preventing Loss

Building a water reservoir is no small feat. The primary challenge lies in containing the precious water within the designated area. Traditional methods often rely on concrete or compacted clay liners. However, these methods can be susceptible to cracking and leakage over time, leading to significant water loss through seepage. This not only undermines the project’s effectiveness but also raises environmental concerns.

The Solution: A Geosynthetic Shield

This is where our Ocean HDPE Liner-1.5MM stepped in. This high-density polyethylene (HDPE) liner is a robust and impermeable barrier. During installation, a massive 12,000 sqm of this liner was laid across the base and sides of the reservoir. The HDPE liner acts as a virtually leak-proof shield, preventing water loss through seepage. This ensures that the collected rainwater remains within the reservoir, maximizing its availability for the community.

Here’s what makes Ocean HDPE Liner-1.5MM the perfect fit for water reservoir projects:

  • Exceptional Impermeability: The HDPE material boasts a very low permeability coefficient, meaning it excels at preventing water from passing through. This minimizes water loss and ensures the reservoir functions at optimal capacity.
  • Durability and Longevity: Made with high-quality HDPE, our liner is resistant to UV radiation, chemical degradation, and punctures. This translates to a long service life, minimizing the need for frequent replacements and maintenance.
  • Environmentally Friendly: Unlike traditional methods that can involve significant excavation and disruption of natural habitats, geosynthetic liners offer an eco-friendly solution. They minimize environmental impact and ensure the sustainability of the project.

Beyond Containment: Protecting the Foundation

While the HDPE liner acts as the primary barrier, another crucial element contributes to the project’s success – the Ocean NonWoven Geotextile-250GSM. An additional 12,000 sqm of this geotextile was laid underneath the liner, serving multiple purposes:

  • Protection from Subgrade Damage: The geotextile acts as a cushion, protecting the liner from sharp objects or unevenness in the underlying soil. This minimizes the risk of punctures and ensures the integrity of the liner is maintained.
  • Enhanced Drainage: The non-woven structure of the geotextile allows any water that might infiltrate through cracks or minor imperfections in the surrounding soil to drain away efficiently. This prevents water buildup behind the liner, which could lead to pressure and potential damage.
  • Cost-Effectiveness: Geotextiles offer a cost-effective solution compared to traditional methods like using thick layers of sand or gravel for drainage.

A Reservoir of Hope

The Sundargarh water reservoir project exemplifies the power of geosynthetics in water management. By utilizing Ocean HDPE Liner-1.5MM and Ocean NonWoven Geotextile-250GSM, the project engineers ensured:

  • Efficient Water Storage: The impermeable liner minimizes water loss, maximizing the amount of water available for the community.
  • Long-Term Sustainability: The durability of the geosynthetics safeguards the reservoir’s functionality for years to come.
  • Environmental Responsibility: The project minimizes environmental impact and promotes sustainable water management practices.
