Hi Gordwin,
I think Ajit was referring to this document from 1983 which Brian had posted:

documents.worldbank.org/curated/en/70404...astewater-management

Feachem, Richard G.; Bradley, David J.; Garelick, Hemda; Mara, D. Duncan; Feachem, Richard G.*Bradley, David J.*Garelick, Hemda*Mara, D. Duncan. 1983.
