Southern Nevada Water System (SNWS) switched from constant rate to variable rate filtration in
1997. By pumping and treating water at maximum rate during nighttime hours and then cutting
back during the daytime, when power rates are higher, operating costs have been significantly
reduced. There is some concern that variable rate filtration could have a negative impact on
filtered water quality. Preliminary studies in 1999 and 2000 showed no such adverse effects at
SNWS. The current study further supports this conclusion and suggests that, if the filtration rate
is changed gradually over several hours, variable rate filtration can yield improved water quality.
