| Recharge
program gains worldwide attention
The Southern Nevada Water Authority (SNWA) operates one of the most
sophisticated and successful artificial recharge programs in the
world. This practice of injecting water underground during the months
of October through May has replenished the valley's groundwater
aquifers, which have suffered water-level declines due to excessive
groundwater pumping in the past.
Water agencies and engineering firms from around the world come
to Las Vegas to view SNWA recharge facilities, which are operated
on behalf of the Las Vegas Valley Water District and City of North
Las Vegas.
A
Japanese delegation representing the Kansai International Airport
Project recently visited the SNWA recharge facilities to learn more
about groundwater storage and subsidence reduction.
Faced with the challenge of keeping afloat an offshore island containing
an airport runway, the Japanese group hopes the use of injection
water wells will help stabilize the island and decrease subsidence.
In recent years, technologies employed by the SNWA recharge program
also have captured the interest of groups from Brazil, China and
Australia.
The artificial recharge program—a significant part of the SNWA
water resource plan—was developed as a resource option to meet future
needs of the Las Vegas Valley's municipal water ratepayers. Utilizing
more than 50 injection wells, the program has increased groundwater
levels and eased the effects of subsidence in Southern Nevada.
Since 1988, the SNWA has banked approximately 242,000 acre-feet
(78.9 billion gallons) of treated Colorado River water into the
valley's underground basin.
Groundwater
fee reminder . . .
If you have not yet sent payment for the annual Las Vegas Valley Groundwater
Management Program fee, please do so as soon as possible. This billing
was distributed to area well users and groundwater permit holders
in August 2001.
Revenue from the fee is used to accomplish specific program goals,
including aquifer protection, artificial recharge and financial
assistance for well users who volunteer or are required by the Nevada
State Engineer to hook up to a municipal water system.
If you have questions or would like more information about the
fee, visit the Groundwater Fee
page of this Web site or call the Groundwater
Information Line at 258-7288.

There are no requirements for water quality testing for small community
wells or domestic wells. However, it is a good idea to get your
well tested periodically.
The Las Vegas Valley Water District and the City of North Las Vegas
have recharged about 242,000 acre-feet of treated Colorado River
water for future use. This water may be used as a future water supply
for municipal water customers.
Through the Las Vegas Valley Groundwater Management Program, up to
5,000 acre-feet of treated Colorado River water may be recharged annually
to remain permanently in the groundwater basin.
Groundwater Update is published tri-annually
by the Southern Nevada Water Authority (SNWA). Comments or questions
