Objectives of water treatment
•
Production of a safe and aesthetically appealing water that
is protective of public health and in compliance with current
water quality standards.
•
The primary goal of a public or private water utility or
purveyor is to provide treated water without interruption and at a
reasonable cost to the consumer.
