Pond Liners for Water Harvesting: Can they help scale up water storage?

Water harvesting has emerged as a crucial practice whether and turned out to be a sustainable water management solution. Whether for agricultural irrigation, landscaping, or replenishing groundwater, capturing runoff can reduce your reliance on traditional water sources. The use of pond liners stand out as a cornerstone for efficient water retention and management.

It compasses a range of techniques ranging from simple rain tanks to complex systems involving reservoirs and distribution networks.

Pond liners are impermeable membranes or barriers installed at the bottom and sides of a pond to prevent water from seeping into the ground.

Importance of Pond Liners

Pond liners play a pivotal role in water harvesting systems by preventing seepage and leakage, thus maximizing water retention. Without a reliable liner, water stored in ponds or reservoirs can gradually seep into the ground, reducing the effectiveness of the harvesting system and potentially causing environmental damage.

Types of Pond Liners


Made from synthetic materials such as polyethylene, polypropylene, or PVC, geomembranes offer excellent durability and resistance to punctures and UV degradation. They are available in varying thicknesses and can be customized to fit the dimensions of the pond or reservoir.

EPDM (Ethylene Propylene Diene Monomer)

EPDM liners are renowned for their flexibility and longevity. Composed of synthetic rubber, they can conform to irregular shapes and withstand extreme temperatures without deteriorating. EPDM liners are often favored for their ease of installation and resistance to tears and punctures.

Rigid Liners

Constructed from materials like fiberglass or preformed plastic, rigid liners provide a stable and durable option for water storage. While they may be more challenging to install due to their fixed shape, rigid liners offer longevity and are resistant to UV radiation and environmental degradation.

Pond Liner Prices in Kenya

The cost of pond liners is;

  • 0.3 mm – 150 KES per square meter
  • 0.5 mm – 230 KES per square meter
  • 0.75 mm – 340 KES per square meter
  • 1 mm – 450 KES per square meter

Steps to Secure and Anchor your Liner onto the ground

  • Unpack pond liners from the rolls and spread it on the surface.
  • Pull the liner materials and fit it over the excavation.
  • Tuck in the pond liner and ensure it covers every part of the ground without wrinkles.
  • For large ponds create seams to prevent water leaks by conducting welding.
  • Once all surfaces of the pond are secured

Can pond liners scale up water storage

Yes, pond liners can certainly scale up water storage capacity. Pond liners are typically made of materials like reinforced polyethylene or EPDM (ethylene propylene diene monomer) rubber, designed to be durable, flexible, and resistant to UV rays and chemicals. They can be used to create ponds, reservoirs, and other water storage systems of various sizes.

Scaling up water storage with pond liners involves selecting the appropriate liner material and thickness based on factors such as the size of the storage area, intended use of the stored water, and environmental conditions. Larger storage areas may require thicker liners to withstand greater water pressure and potential punctures.

How do I Estimate the Size of the Pond liner I need?

Find out what size of pond liners to use by measuring and calculating the surface of the pond.

The liner is required to cover all parts of the pond excavation including the bottom, walls, and edges.

However, ponds take various shapes as per the land size and terrain. So, the surface of the pond will be entirely covered with a liner. For our case, the formula for calculating the size of the liner needed for common pond shapes exists. Common shapes include rectangular, circular, and rectangular with slanting edges.
