$19-10.$ Using Figure P$-19-9,$ lay out the sewer lines $($placement$,$ direction of flow, and

manhole locations$)$ for the residential area that includes the following streets: Ash,

Sycamore, Forrest, Cedar, Birch, Elm, and Acorn. The mains may connect either to a

trunk line that connects to an intercepting sewer along Main Street or directly to the

intercepting. The trunk line discharges into the WWTP at the junction of Bull Run and

Main Street.

$19-13.$ Design a VCP gravity flow sewer main starting at the intersection of $4$th and G

Streets and ending at the intersection of $2$nd and B Streets $($Figure P$-19-13).$ Prepare

a sewer design table similar to that shown in Example $19-2$ and a profile drawing

similar to Figure $19-13$b$.$ Use the following assumptions: minimum invert depth is

$3\mathrm{.}0m,$ the invert of the sewer entering the main from G Street $($east and west$)$ is at an

elevation of $102\mathrm{.}13m.$ Contributing flows, including I$/$I$,$ from mains are given below.
