Assuming a conservative value for an overflow rate, design several parallel circular sedimentation basins that together must handle a "design" peak daily flow of $0\mathrm{.}05162\frac{m^3}{sec}$ of Alum floc to remove turbidity.

a$.$ Use Table $9\mathrm{.}6($Qasim and in the lecture notes$)$ to select an overflow rate. Conservative means the value that gives you a design that will not fail for all parameter values $($if you have a range of possible values$).$

b$.$ Select the number of basins you feel is reasonable. Justify your answer in a few sentences. You may want to perform several iterative calculations.

c$.$ Determine the diameter of each basin $($select the diameter from standard increments of $1m).$

d$.$ Determine the side$-$water depth of the basin so there is at least $4$ hours of detention time and the basin depth is at least $2\mathrm{.}5m.$ Note, you can design a deeper basin if you decide it is merited. Justify if you do this.
