ICC Sizing Water Distribution, Drainage and Venting Standard Consensus Committee
(IS-SWDDV)
ICC 815 – Standard for Sizing Water Distribution, Sanitary Drainage and Vent Piping Systems
Project Description: As an ANSI-accredited SDO, ICC is developing a new standard to establish minimum requirements for a comprehensive design methodology for sizing water distribution, sanitary drainage, and vent piping systems for residential, mixed-use, and institutional occupancies.
Project need: A new standard would provide a complete plumbing system design method for sizing indoor water, sanitary drainage, and vent piping for residential, mixed-use, and institutional occupancies based on the water use of plumbing fixtures and appliances that are manufactured today, technical advances in estimating water usage pattens and the impact of the COVID-19 pandemic as more people work from home. Pipe sizing provisions in current codes and standards are predominantly based on outdated water usage patterns and do not address post-COVID 19 societal changes.
