Water Savings
To calculate water savings that can be achieved from replacing an existing flushome-

To calculate the simple payback from the water savings associated with replacing an
existing flushometer-valve toilet, consider the equipment and installation cost of the
replacement flushometer-valve toilet, the water savings as calculated using Equation
and the facility-specific cost of water and wastewater.
