15" steel casing extending a minimum 10' either
side of the crossing per Detail G (Sheet 11); add
magnetic warning tape 12" above water and sewer
lines
1. Separation distances shall be measured edge-to-edge.
2. Examples of proposed means to mitigate risks include:
a. remove/replace the aged vitrified clay sewer pipe;
b. replace the aged or cracked existing sewer pipe;
c. use thicker or higher pressure class PVC instead
d. of the typical thin-wall sewer pipe; install an in-situ lining to the existing sewer pipe for XX feet;
e. center the sewer line over the crossing to keep the joints as far as possible from the water line;
f. add detectable or magnetic warning tape placed 12 inches above the sewer and/or the water line(s) to minimize possible damage during future excavations;
g. use HDPE pipe for water line or sewer line to eliminate the joints [if there is no sagging or lack-of-sufficient slope problems for HDPE sewer pipes];
h. use restrained joints for water line and/or sewer line near the crossing
