The town utilizes membrane filtration technology. The current plant is reaching its expected life. So in 2012 the membranes will be changed out and replaced with even more state of the art membranes. The excerpt below was copied from the US Filter supplier web site.

 MEMCOR® CP - Ultrafiltration System
Keep it simple; and achieve the lowest treated water cost. The Memcor CP, is a pressurized, pre-engineered membrane system. Its modular "building block" configuration simplifies design, reduces installation and makes operation easy. The robust Memcor hollow-fiber technology provides a verifiable barrier, assuring virus, turbidity, suspended solids, and pathogen removal. The compact configuration reduces overall system footprint, allowing up to 10 MGD (40 MLD) of treated water capacity on one skid. Simple. Reliable. Cost effective.

Ideal for gravity-driven systems, treatment requiring coagulants and pretreatment to RO applications such as drinking water, desalination, reuse and industrial applications, the Memcor CP is able to meet a fast-tracked installation schedule and produce superior water quality.

Memcor CP System provides:
* Bacteria and protazoa > 6-log removal
* 0.04 micron pore size fiber
* 30% flow increase in same footprint
* 30% reduction in energy
* 98% overall system recovery (based on surface water testing)
* Silt Density Index (SDI) less than 2.0 and turbidity less than 0.02 NTU
