1) Trench drains typically drain to an interceptor. Test trench drains and all floor drains in the
Auto Center.
E. Procedure:
1. Test each drain separately according to the procedure outlined.
2. Locate drains to be tested. Locate grease and oil interceptor. Open the manholes over the grease and oil
interceptor and verify that it is the correct structure.
3. Station one person at the interceptor with the manhole open. Barricade the area appropriately to prevent
accidental personnel or vehicular entry. Station another person at the inside drain to be tested. Connect
hose to a nearby spigot (usually located in the bakery department) and remove the cover over the floor
drain. Avoid spilling water on the sub-grade.
4. Notify person at interceptor by radio that the test is about to begin. Add water from the hose into the floor
drain and inject dye into the water stream. Notify person at interceptor that the test has begun. The person
at the interceptor shall notify the person at the floor drain as soon as the dye appears at the interceptor. The
dye at the interceptor should generally appear within ten minutes from the introduction of the dye into the
floor drain.
5. If the dye does not appear at the interceptor, continue to add dye with the running water and open cleanouts
to check if any dye is apparent in the lines. Document which cleanouts do and do not have the appearance
of dye. Check all other interceptors to determine presence of dye.
6. If dye is not detected at any of the inspected locations, inspect the nearest manhole of the sanitary sewer
system for the presence of dye. If there is a retention pond onsite, inspect the pond for the presence of dye.
7. Document dye test activities including the time dye was added at each drain location and the time period
between when dye was added and when it was detected. Identify any irregular occurrence of dye in the
interceptors, cleanouts, or sewer lines.
8. Upon completion of testing, replace all floor drain, vault, and manhole covers. Notify the Wal-Mart
Construction Manager when the testing has been completed.
