The world is changing and so is our climate. Unpredictable seasons and changing rainfall patterns are becoming the norm. We cannot continue to rely on the rainfall patterns we used to have and we have to find new ways to provide water for all our uses including irrigation. As farms need huge amounts of water, storing water in plastic tanks is financially untenable and, in some cases, drilling costs may be out of reach.
For this reason, digging a water pan is the most economical model for storing water. Unfortunately, water will leak into the ground from the water pan. That’s where having a dam liner prevents the water loss by infiltration.
A dam liner is an impermeable Geo-membrane used for retention of liquids, including the lining of reservoirs, retention basins, hazardous and nonhazardous surface impoundments, garden ponds and artificial streams in parks and gardens.
The price of dam liners in Kenya is determined by their thickness which ranges from 0.3mm to 1mm.
The choice of which dam liner to use is determined by the following factors.
- The surface on which it will be placed. The rougher the surface the thicker the dam liner should be.
- The volume of water to be stored. The higher the volume the thicker the membrane should be.
Generally, dam liners are UV treated to ensure longevity and should last from 12 years for the 0.5mm thick to 35 years for the 1mm one.
The longevity is only achieved with the correct use.
In Kenya, the price of dam liners should range from Ksh 200 to Ksh 380 per square meter and vary depending slightly depending on the supplier you purchase from and your location.
