Benjamin Franklin is frequently quoted as having said: "We will never know the true value of water until the well runs dry." Although conservation was the first attempt at preserving and maintaining limited fresh water supplies, the idea of "reclaim, recycle, and reuse" was the next push for managing them.

Water reuse has gone from being a positive environmental alternative to a growing necessity. Reusing wastewater saves money and the environment, but it can be expensive to pipe treated water through miles of distribution lines from a centralized reclamation facility to where it is needed.

Over the past few decades there has been an increased awareness of the importance of water quality. Many municipalities and industrial facilities have upgraded or installed new technologies to meet the demand for clean water. Advances in water quality science show that further improvements are needed to ensure a plentiful water supply and to protect the natural environment.

Membrane bioreactor (MBR) has emerged as the wastewater treatment technology of choice for an increasing number of municipalities over the last five years. This growth is driven by the very high quality effluent produced by MBR -- exceeding strict standards or ideal for direct reuse -- and is fuelled by a steady reduction in treatment cost resulting from improvements in membrane productivity.
