The pond has a rectangular shape with dimensions as follows: length $(L)=50$ meters,

width $(W)=30$ meters, and a maximum depth $($D$)$ of $5$ meters. The wastewater in the

pond has a specific gravity of $1\mathrm{.}1$ and a temperature of $20C.$ Calculate the required

thickness of the geomembrane to prevent leakage, considering a safety factor of $2\mathrm{.}0.$
