Note: Contractor shall disregard line weights shown (thick vs. thin). Line weight does not indicate demo or existing conditions on these drawings. Follow graphic symbols, notes, and keynotes for scope of work.

Once building 4 has been connected into the dual walled fiberglass piping, the contractor shall cut off old wastewater piping from building 4 and cap it to prevent wastewater from buildings 5 and 174 flowing into abandoned section. Contractor shall add piping that will turn up and create a clean out for buildings 5 and 174. Clean out shall be accessible from the surface and have a removable cap rated for vehicle traffic.
