History of Water Treatment |
The need for a clean, safe and
reliable source of water has been a driving force of human civilization.
Population centers would accumulate and grow around areas of clean water.
Ancient humans recognized that a source of nearby water was a necessity. Its
presence was essential to all life, not just for their own uses, but critical
for the animals they hunted, and plants they harvested.
4000 years ago, in India and parts of China, the Hindu’s devised the first
recorded drinking water standards. It directed its people to heat foul water by
boiling and exposing to sunlight and by dipping seven times into a piece of hot
copper, then to filter and cool in an earthen vessel.
This enlightened treatment not only produced aesthetically acceptable water, but
a disinfected potable source. This treatment was a directive intended for
individuals and families, not a community water supply.
Only after the Dark Ages, due to advances in science and technology, was there a
realization that clean looking water was not necessarily safe water. Before the
invention of the microscope, the idea of microscopic life was unimagined. Even
with that tool it still took over 200 years before a connection between microbes
and disease was made. In the mid 19th Century it was proven that cholera was
spread by contaminated waters. By the late 19th Century, Louis Pasteur developed
the particulate germ theory of disease, which finally established a cause and
effect relationship between microbes and disease.
Filtration of water was established as a method of clarifying water in the 18th
Century. In 1832 the first municipal water treatment plant was built in
Scotland. Unfortunately the aesthetic properties of the water were the major
concerns of the time, while effective water quality standards remained absent
until the late 19th Century.
In the US, municipal water systems originated as early as 1799, by 1860 over 400
were in service providing water to major cities and towns. Because water quality
standard were lacking, these systems contributed to major outbreaks of disease
by spreading pathogenic organisms.
In the 1890’s effective water treatment techniques began to develop. Coagulation
and rapid sand filtration were instituted, which significantly reduced both
turbidity and bacteria in water supplies. Chlorination of water was eventually
introduced in 1908. Finally a community's water supply could, in fact, be
considered safe.
Buffalo’s water system history began in 1827, when the Buffalo & Black Rock
Jubilee Water Works was formed. It supplied well and spring water through an
assemblage of wooden pipes. In 1852 the Buffalo Water Works Co. formed, and
pumped its water from the Niagara River. The City of Buffalo purchased both
companies in 1868 and began construction of an Intake and tunnel system in the
Niagara River. This location proved unfortunate. River turbulence and shoreline
pollution caused a public outcry for a new intake. In 1913 this new intake was
completed. It was located upstream from the original one, in Lake Erie’s Emerald
Channel. In 1914 Buffalo began chlorinating its delivered water, and in 1926 the
Water Treatment Plant was built utilizing coagulation and filtration along with
disinfection of its delivered water.
