Commercial plumbing projects can involve requirements that differ from ordinary residential repairs.
The City of Sterling Heights administers plumbing permits and inspections through its Office of Building.
Depending on the scope of work, commercial plumbing alterations, new installations, and certain equipment replacements may require permits and inspections.
Commercial Drainage & Grease Management
Sterling Heights also regulates certain wastewater discharge activities.
The city’s sewer regulations address grease, oil, and sand interceptors used to prevent harmful materials from entering the sanitary sewer system.
Restaurants and vehicle service garages have specific interceptor requirements under the municipal code.
These systems must meet applicable requirements for capacity, accessibility, cleaning, and inspection.
Businesses should understand which requirements apply to their operations before making significant changes to drainage infrastructure.
Backflow Prevention
Commercial plumbing systems may also require appropriate protection against cross-connections that could allow contaminated water to enter the drinking water supply.
Michigan’s cross-connection control requirements address inspections and testing of applicable backflow prevention devices.
The appropriate protection depends on the plumbing application and the degree of potential contamination risk.
Commercial plumbing work should account for applicable local codes, permits, and specialized system requirements.
