Elevator related code requirements are set forth in ASME A17.1 “Safety Code for Elevators and Escalators”, CSA B44 “Safety Code for Elevators”, as well as The Texas Department of Licensing and Regulations. The code is published by the American Society of Mechanical Engineers and is a widely accepted and recognized handbook in the building code and engineering industries.
ASME A17.1/CSA B44 requires that all elevator pits for elevators that have Firefighters’ Emergency Operation, be provided with a drain or sump pump. The pit drainage shall be designed to remove a minimum capacity of 3,000 gallons per hour (or 50 GPM) per elevator car.
Where this elevator waste is discharged to (and how it is treated) is a different story, that is most often dictated by the Authority Having Jurisdiction. The jurisdiction will outline whether the discharge is routed to a sanitary sewer or storm system, whether it is directly or indirectly connected, or if additional protection (such as oil/water separation or an oil-sensing alarm) is required.
In the City of Austin, elevator discharge must comply with the requirements set forth by the City of Austin Industrial Waste Department. This department will review substantially complete plans to verify that elevator discharge is compliant with their standards. Official sign-off is required from Industrial Waste prior to the issuance of a building permit.
Some pertinent City of Austin Elevator Discharge requirements are as follows:
In summary, the requirements for drainage of elevator pits is dictated by ASME A17.1 “Safety Code for Elevators and Escalators”, CSA B44 “Safety Code for Elevators”, as well as The Texas Department of Licensing and Regulation. The authority having jurisdiction will provide mandates outlining the requirements for the discharge and treatment of the elevator waste. It is important to factor in review time necessary for the Jurisdiction’s Industrial Waste/Pretreatment Review as this process can often take weeks to complete and approval is necessary prior to permit issuance.
