SECTION 4 – Plumbing
Existing Conditions
The building was constructed in 2005-6 and all systems are original to the building. The building was constructed prior to recent lead-free standard and should be considered as future renovations are made. Unless noted otherwise, the piping systems, equipment and components are in good condition.
Storm System
Roof drains are routed internally to columns or exterior walls and then to the exterior of the building where it is collected via an underground site storm system and exits the building in two (2) locations closest to the large parking lot. One exit is on the south building side and the other exit on the north side.
The areaway storm drains on the north side are collected and routed underfloor to the storm ejector pit located in the basement mechanical room of building 185. The 48” diameter by 84” deep pit has duplex submersible pumps with capacity of 200 gpm for each pump at 25 feet total dynamic head and 5 HP each at 460 volts. The pumps are controlled with an automatic float system and wired through a control panel. This pump system is connected to the building for any alarms.
Sanitary System
Sanitary waste for floor drains, sinks, water closets, urinals, lavatories, janitor’s sinks, pantry sinks and electric water coolers are routed underfloor and vented overhead. The sanitary piping is no-hub cast iron and is routed underfloor to the exterior where it is collected via an underground site sanitary system to exit building west toward the Visitor’s parking lot.
The basement mechanical room floor drains and utility sink on legs are collected and routed underfloor to the sewage ejector pit. The 42” diameter by 72” deep pit has duplex submersible pumps with capacity of 150 gpm for each pump at 25 feet total dynamic head and 5 HP each at 460 volts.
