FIGURE P$-19-9$

Map for sewer layout. Elevations are in meters above mean sea level at points noted by dots. These are not manhole locations.

$($Adapted from Metcalf & Eddy, $1981.)$

$19-10.$ 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.

$19-11.$ Design a VCP main for the Bastogne Retirement Center $($Figure P$-17-23)$ by preparing a sewer design table similar to that shown in Example $19-2$ and a profile drawing similar to Figure $19-13$b$.$ Mark and number the manhole locations on a copy of Figure P$-17-23$ in Chapter $17.$ The sewer design is to terminate at
