Primary maritime pump applications include CHT of
wastewater, brine, bilge and Graywater pumping.
With appropriate treatment and maintenance of reuse systems, Graywater could provide a safe and
reliable local water supply for water-scarce cities.
Using treated Graywater to meet water demand for toilet flushing and laundry has the potential to reduce
demand by nearly 36 percent.
The study's committee, on which I served, concluded that reusing Graywater can improve water conservation by expanding
local water supplies and providing a drought-resistant year-round local water source.
If water conservation is the primary goal, the first step should be reducing outdoor water use,
not using Graywater to preserve landscaping that is inappropriate for local climate conditions.
The National Academies of Sciences, Engineering,
and Medicine recently published a report that analyzes the potential of Graywater reuse, available treatment technologies
and the human health and environmental risks associated with Graywater reuse.
In drought-stricken regions, households and businesses have already started to reuse Graywater, and some builders are installing dual plumbing
systems in new developments to supply treated Graywater for toilet flushing and possibly other nonpotable uses, such as watering gardens.
