Zimmerman is Kohler’s senior staff engineer for water conservation initiatives. He presented his material in tandem with interior designer Jamie Gibbs.
The workshop took place on the trade show floor on a stage divided into three parts that could present that many workshops simultaneously. Sponsors for the area, known as the Kitchen-Bath Showcase, included Kohler (Platinum), Sterling (Gold) and Bath & Kitchen Pro magazine (Silver).
At least half of Zimmerman’s strategies hinted at his potential areas of concern for water-saving products. These are:
Drainline carry. Even though a California study on high-efficiency toilets suggests this won’t be a problem, isolated problems are likely.
Cross connections. Systems for potable water and rainwater/graywater in the same building must be kept separate.
New equipment. New products that require filtration or ultra-violet disinfection must be maintained properly. Homeowners, many of whom forget to change their furnace filters, must adjust their habits if new products are to provide lasting effectiveness.
Building designs. The quest for efficiency may constrain a building’s size and shape. Multifamily and neighborhood designs may become more common.
