Dam liners definition- Dam liners are thick sheets of polythene that are used to cover separate water from the ground where it is being stored. Dam liners are used to harvest water in places where the soil is porous. Harvested water is stored for future use. For example, during the rainy season, water can be harvested for irrigation, drinking, or other domestic uses during the dry season.
What kinds of liners are best for ponds?
The best dam liner to use depends on the water held and the surface type. If it is a large reservoir, a thicker liner is better. If the surface is smooth then a lighter gauge liner will work.
What are the different types of dam liners in Kenya?
Dam liners are found in different thickness sizes which include; 0.5mm, 0.8mm, and 1mm thick. They are in widths to fit the size and shape of the reservoir or tank.
How is the thickness of dam liners determined?
The amount of water being stored in the storage area. The more the amount of water being stored, the heavier it will be hence a thick dam liner will be required while the lesser the amount of water being stored the lighter it will be and the less thickness of a dam liner will be required.
The floor texture of the ground. If the floor of the storage area is rough, one will go for a thicker liner to prevent it from being torn by the rough surface. If the surface of the floor is smooth, one will go for a lighter liner as there are minimum chances of it being damaged by the floor.
