Erie's 2006 Uniform Development Code and Standards and
Specifications for Parks and Recreation Construction recommend
low water use landscaping designs, good soil preparation, and
efficient irrigation equipment.
Erie currently reuses non-potable water to irrigate a portion of
Vista Ridge and is currently developing a Non-Potable Water
Master Plan. This Master Plan will be used to develop a
distribution system for reclaimed and raw water supplies.

Erie has metered and billed customers based on the amount of
water they have used since 1972. This has proven to be effective
in making customers financially liable for the amount of water they
use and consequently increased customers' awareness on water
consumption.
Erie currently meters water treatment production, diversions of
their ditch water, as well as records calls for CBT and Windy Gap
water. Erie plans to the monitoring of source water stored in their
raw water reservoirs and conveyance system. This monitoring data
could provide valuable information on what improvements could be
made to minimize s stem water losses.
Erie began to replace meters older than 10 to 12 years in 2005.
This improves metering reliability and helps to ensure that
customers are accurately billed for the volume of water consumed.
This also improves Erie's ability to evaluate system water losses
and/or infiltration of water into the distribution s stem.
Erie's current billing system consists of two categories: residential
and commercial. The commercial billing category includes
commercial use, light industrial use, parks irrigation, as well as
HOA irrigation. Because a variety of customer types are grouped
into commercial, it is difficult to monitor water usage among the
customer types.
Erie plans to divide these customer types into individual billing
groups, enabling their water usage to be more easily tracked
among customer types.
Unmetered water accounts for approximately 15 percent of Erie's
total annual water use. Erie plans to begin metering hydrant
flushing during the summer of 2007. This will reduce the amount of
unaccounted for water and subsequently improve Erie's ability to
estimate distribution s stem water losses.

Erie's leakage detection program has been useful in detecting
leaks and the repair of these leaks has reduced system losses.
Erie plans to continue to implement this program, focusing on
certain areas of the distribution system each year.
The SWRF has historically used potable water for the flushing and
cleaning of the plant. Erie plans to use treated reclaimed water in
the future, reducing the plant's potable water usage.
