Abstract

Backwater valves in sanitary sewer laterals have become a primary mechanism for reducing the risk of basement flooding in residential homes. Despite widespread reliance on these devices to prevent sewer back-up, the performance of backwater valves during significant rainfall events is mostly unknown. Using a questionnaire-based approach followed by an in-field site visit, this paper identifies installation and maintenance as the two key factors that lead to potential failures of backwater valves. Among the results discussed, failures were linked to a general lack of knowledge on backwater valve devices and the maintenance procedures required to ensure adequate performance.
