Scope and Application of OBC Part 7
General Plumbing Application
Part 7 applies to the comprehensive design and construction of plumbing systems. Its primary objective is to ensure the health and safety of occupants by regulating water distribution and waste disposal. Under Section 7.1.1.1, all new plumbing installations must adhere to these specific guidelines to pass municipal inspections.
Industrial Process Systems and Interconnection
A notable exception in the code involves industrial process systems. While these systems are typically exempt from Part 7, any interconnection with the building's plumbing system triggers strict compliance requirements. These interconnections must be designed to prevent contamination or malfunctions that could compromise the local water supply.
Definitions and Required Facilities
Defining 'Storey' for Plumbing Compliance
The OBC provides a specific definition for a 'Storey' within Part 7. It refers to the interval between two successive floor levels—including mezzanines containing plumbing fixtures—or the space between a floor and the roof. This definition is pivotal for calculating hydraulic loads and venting configurations.
Plumbing Facility Requirements
According to Section 7.1.1B.1, plumbing facilities are mandated based on the occupancy requirements found in Subsection 3.7.4 and Section 9.31. These regulations ensure that buildings provide a sufficient number of fixtures to accommodate their intended use, maintaining high standards of hygiene and accessibility.
