Doug's background is in the semiconductor capital equipment industry. His engineering and business management background lead him to found three companies, invented numerous production products, related to reducing contamination in clean rooms and increasing semiconductor production yields. He founded his 4th company Phase Four Industries in 1998 specializing in RV waste management.
Camping was their family's method of enjoying the great outdoors beginning in tents and graduating to a Class A motorhome 2 years before retiring. Doug an inventor by nature decided very quickly that dumping holding tanks on RVs was in need of a better method. After retiring in 1991 he and his wife of 30 years began full time RVing in a bus conversion. As they traveled Doug continued to educate himself on the best method of transferring waste from RVs to a sewer inlet. He spent a lot of time talking with other RVers as well as watching folks dump their tanks at RV sites and dump stations.
He discovered that everyone had his/her own variation of how to do this task without getting ---- on themselves or on the ground around them. More often than not during the dumping process some liquid from the holding tanks would end up on the ground around the dump inlet. Sometimes it was during hose and fitting cleaning prior to storage, other times it was due to hose failure or fitting leaks.
Having full time RVed for 9 plus years and dumped his own tanks hundreds of times with a focus on “a better method” to make this unsanitary necessity of the RV lifestyle he joined the Technical Plumbing Subcommittee with the Recreational Vehicle Industry Association (RVIA) to help create standards for RV manufacturers to provide a system that eliminates this negative aspect to a great lifestyle. RV manufacturers use the National Fire Protection Association, NFPA 1192 Standard on Recreational Vehicles 2005 Edition as their standard by which they build RVs of all kinds.
Doug has done seminars at most retail RV shows across the country, trained sales and service technicians at RV manufacturers and dealerships on the dumping process. He is available to directly answer questions related to dumping holding tanks in a new forum aptly titled “Ask Dumper Doug”.
