What publication mandates the installation of Black Water Holding Tanks (BWHT) and Grey Water Holding Tanks (GWHT)?

The requirement for the installation of Black Water Holding Tanks (BWHT) and Grey Water Holding Tanks (GWHT) is primarily governed by specific standards and codes pertaining to RV manufacturing and installation. NFPA 1192 is published by the National Fire Protection Association and addresses the safety and performance of recreational vehicles, which includes provisions for sewage disposal systems like BWHT and GWHT.

CSA Z240, on the other hand, is a standard from the Canadian Standards Association that covers RVs and includes relevant details about wastewater management as well.

Therefore, the correct choice is that both NFPA 1192 and CSA Z240 mandate the requirement for these holding tanks in RVs, as they help ensure safety and compliance with sanitation regulations. The idea that neither of these publications mandates the installation of BWHT and GWHT is not accurate, as both play a significant role in outlining the necessary requirements for proper waste management in recreational vehicles.
