The Town of Franklin, UT depends on chlorinated spring water from surrounding mountains for their water supply. During the spring months, runoff made the water turbid so the city hired Forsgren Engineering to complete a facility planning study. Their findings led to the decision to employ membrane treatment technology.

A pilot trial, completed during spring runoff, confirmed that feed water turbidities, as high as 40 NTU (nephelometric turbidity unit), were successfully treated through the membrane system, which incorporated an AltaFilter™ provided and installed by WesTech Engineering.

The membrane system is configured in two banks, each with six modules. There are two open slots on each bank for future expansion. Franklin also faced challenges regarding their waste streams. The water treatment facility is located on a small piece of land, without a sewer connection. WesTech’s solution was to include two extra modules which further concentrate the backwash water, raising facility efficiency to over 98%. “The total system gives us good, safe drinking water and resolves our problems for decades to come,” says plant operator, Cory Richards.
