According to the **Central Water Commission**, more than 70% of Rajasthan’s geographical area is classified as arid or semi-arid. This makes efficient water storage systems not just a necessity but a lifeline for agriculture, industry, and domestic use. In 2025, a leading agro-industrial entity based in **Jaipur, Rajasthan**, partnered with Ocean Non Wovens to construct a **water storage pond using Ocean’s HDPE Liner 750 Micron**. The aim was to develop a high-capacity, long-lasting solution for irrigation water retention in an area prone to evaporation and seepage. ### The Growing Role of Geosynthetics in Water Storage Applications Traditional ponds made with compacted soil or concrete often suffer from seepage, erosion, and high maintenance costs. This is where **geosynthetics—particularly HDPE geomembranes—offer superior performance**: - **Seepage Prevention:** HDPE liners have an extremely low permeability (less than 1 x 10⁻¹³ cm/s), making them nearly impermeable. - **UV & Chemical Resistance:** Essential in regions like Rajasthan, where high solar radiation and saline water are common. - **Durability:** High tensile strength and resistance to punctures and stress cracking ensure a lifespan exceeding 20 years with proper installation. - **Flexibility:** Adapts to irregular pond geometries and differential settlement without cracking. According to a 2022 report by **Global Geosynthetics Market Outlook**, HDPE geomembranes are among the fastest-growing segments in the geosynthetics industry, with the water conservation sector accounting for over 25% of its usage globally. ### The Jaipur Project: Technical Insights & On-Ground Implementation **Scope of Work:** The client required a water retention pond to support year-round irrigation for over 100 acres of farmland. With erratic rainfall and high infiltration rates in the region’s sandy soils, traditional pond designs had proved ineffective in the past. **Material Supplied:** Ocean Non Wovens supplied **5,500 SQM of Ocean HDPE Liner 750 Micron**, which was installed over a pre-excavated pond base. **Product Technical Specifications:** | Property | Specification | | --- | --- | | Thickness | 750 Micron (0.75 mm) | | Material | [High-Density Polyethylene](https://en.wikipedia.org/wiki/High-density_polyethylene) (HDPE) | | Tensile Strength (ASTM D638) | ≥ 25 kN/m | | Puncture Resistance | ≥ 600 N | | UV Resistance | > 90% strength retention @ 1600 hrs | | Seam Strength (Welded) | ≥ 90% of parent material | | Chemical Resistance | High (suitable for fertilizers, waste) | **Installation Process Overview:** 1. **Base Preparation:** The pond bed was graded, compacted, and cleared of all sharp objects to prevent liner damage. 2. **Panel Laying:** HDPE sheets were rolled out with 150 mm overlaps, aligned according to wind direction to minimize uplift. 3. **Welding:** Double hot wedge welding was used for primary seams, followed by extrusion welding for T-joints. 4. **Quality Assurance:** Air pressure testing and spark testing were conducted to check for seam integrity and puncture vulnerabilities. 5. **Protection Layer:** A geotextile cushion layer was laid under and above the liner for enhanced protection and longer service life. ### Impact: Tangible Benefits Delivered The use of Ocean HDPE Liner resulted in **a complete elimination of seepage loss** and significantly improved the client’s ability to store and manage irrigation water efficiently. The impact is measurable and multifaceted: - **Water Conservation:** Prevented an estimated **1.2 million liters/month** of seepage loss. - **Operational Savings:** Reduced pumping cycles and energy costs by 25%. - **Long-Term ROI:** With a lifespan of 20+ years, the total cost of ownership was significantly lower than concrete-lined alternatives. - **Rapid ROI Recovery:** The project paid for itself in less than 3 cropping seasons. ### The Overlooked Aspects: What Most Don’t Mention While most case studies emphasize liner strength and waterproofing capabilities, our real-world experience uncovers **less-discussed but critical advantages** of HDPE geomembranes: #### 1. **Algae and Biofilm Resistance** Pond liners with poor surface finish promote algal buildup, which reduces oxygen levels and affects water quality. Ocean’s HDPE liner 750 Micron has a smooth finish that discourages biofilm formation—ideal for agricultural ponds. #### 2. **Thermal Insulation** The thick liner provides partial thermal insulation, reducing water temperature fluctuations that could otherwise harm sensitive crops or aquaculture operations. #### 3. **Resistance to Root Penetration** In areas where trees or invasive plant roots can puncture traditional liners, our HDPE liner 750 Micron acts as a reliable root barrier—critical in rural Rajasthan where Acacia and Neem are common. #### 4. **Ease of Repair** Our liner comes with **on-site repair kits and training**, enabling clients to perform emergency patching with minimal downtime—a value-add not commonly offered in the industry. ### Why Ocean Non Wovens?
