Land, Brenda . 2004. Portable Vault Toilet Service Unit. 0423 1304P. San Dimas, CA: U.S. Department of Agriculture, Forest Service, National Technology and Development Program. 4 p.

Field personnel asked the San Dimas Technology and Development Center (SDTDC) to find a better method to empty vault toilets. The grinder pump and poly tank used by districts to empty toilet vaults caused frequent pump jams that had to be cleared by hand. SDTDC developed the specifications and Marsh Industrial fabricated and manufactured a small vacuum pump service unit as a better method of emptying vault toilets.
