PART I $-$ Determine sewer proflie elevations.

Instructor shouid determine a hypothetical percent of slope for the proposed

sewer line and an invert elevation of the sewer line starting at Sta. $0+00$

Known: Sewer line percent of slope:

$2\mathrm{.}00\%$

Invert elevation at Sta. $0+00$ is $14\mathrm{.}50$

Using the known data calculate each proposed sewer elevation for every $25$ foot

station.

Formula: Station $\%=$ V$.$D$.$

then

V$.$D$.+$ Beginning Elev. $=$ Sewer elevation at that station
