The FTH systems in Koyukuk were installed as a demonstration project with the idea that if they work out then more units may be installed later. However, the City of Koyukuk has not had the financial or technical capacity to operate the project successfully. Cowater visited the project three years ago and assisted homeowners to service their systems. However, Koyukuk needs to install additional units so that they can operate a financially viable haul service.

A unique feature of this project was the construction of a pipeline from the dumpsite to the lagoon. This feature worked out very well.
