The act allocated $906.9 million for the drinking water fund
and $1.489 billion for the clean water fund, restoring most of
the monies cut in last year’s budget sequestration. Last year,

or in part by SRF loans follow new “Buy American” require-

and steel products were not available in suffcient quantities
or of satisfactory quality. WW
