Calculating the size of a damliner required for dam lining or fish pond lining is always a challenge to farmers. A simple damliner calculator will help you solve this.

How to Calculate damliner required for rectangular reservoirs/ponds

To determine the damliner size required use the damliner calculator formula:

Length: add overall length plus twice the maximum depth width plus allowance of a meter or more on either side for overlap

Width: add overall length plus twice the maximum depth width plus allowance of a meter or more on either side for overlap

For example. Assuming you have a pond measuring 10m length , 4m width and 2.5m depth. Damliner required =

L= L+2*D+(1+1)

W= L+2*D+(1+1)

L= 10+(2*2.5)+2

  = 10+5+2

  =17m

W= 4+(2*2.5)+2

    = 4+5+2

    =11m

So damliner required= 17m x 11m.

Note that 2m is the allowance to allow for overlap that will ensure the damliner is properly covered.

How to calculate damliner required for cylindrical/circular reservoirs

For cylindrical tanks, just add the diameter of the tank plus twice the height plus a small allowance on either side for overlap.

Example

Tank Diameter= 10m

Height= 2m

Damliner required

L= 10m + (2×2)+ (0.5+0.5)

=10+4+1

=15m

Since it’s a circular tank, the length equals the width, so width = 15m.

Damliner required = 15m by 15m = 225m2

Please note that circular structures use more damliners and carry less water than rectangular/square structures for the same liner size. So always strive to have rectangular or square reservoirs.
