The project was a washout due to lack of funding and support.
Washout is formed from "wash" (from Old English *wæscan*, meaning to cleanse with water) and "out" (meaning away or outside). The word describes the act of washing something away or the result of something being washed out, often referring to erosion or the removal of material.
Think of 'washing' something 'away' — that's why washout means something that has been washed out or removed.
