If the Division or the appropriate district board of health
approves the use of water hauling:
1.
The water must be obtained only from a source that:
(a) Meets primary and secondary standards;
and
(b) Has been approved by the
Division or the appropriate district board of health before the water is
obtained.
The supplier of water shall provide the Division or the
appropriate district board of health with evidence of compliance with this
subsection.
2.
The supplier of water shall provide for:
(a)
The sanitary transfer of water from its source to the tanks used for water
hauling and from those tanks to the tanks owned or used by customers of the
public water system.
(b) The
sampling and analysis of the hauled water, at a frequency approved by the
Division or the appropriate district board of health, to determine whether the
hauled water meets primary standards for coliform bacteria. If the water in any
vehicle fails to meet those standards, the vehicle must not be used for water
hauling until further testing indicates that the contamination has been
eradicated. The supplier of water shall provide the Division or the appropriate
district board of health with evidence of compliance with this
paragraph.
(c) The sanitation and
disinfection of the tanks used for water hauling and of the lines and
appurtenances used for the transfer and distribution of the water. After it is

(1) Such a tank, line or appurtenance must be
disinfected in accordance with American Water Works Association
Standard C651, as adopted by reference in NAC 445A.6663. The disposal
of any spent chlorine solutions must be coordinated with the Bureau of Water
Pollution Control of the Division.
(2) An analysis of the tank, line or
appurtenance which indicates that it meets primary standards for coliform
bacteria must be obtained and reported to the Division or the appropriate
district board of health.
3. The chlorine residual in the hauled water
must be not less than 1 mg/l and not more than 5 mg/l.
4. Except as otherwise authorized by the
Division or the appropriate district board of health, the vehicles used for
water hauling must be used only for the distribution of potable water and must
never have contained, hauled or carried any materials or substances other than
water from a source approved by the Division or the appropriate district board
of health.
5. There must be no
modification of the facilities where the water is obtained or the tanks in
which the water is hauled without the prior approval of the Division or the
appropriate district board of health.
6. The tanks used for water hauling must be
cleaned and disinfected with a chlorine solution, at such frequencies as the
Division or the appropriate district board of health determines appropriate, in
accordance with the following procedure:
(a)
A sufficient amount of chlorine must be added to the tank to bring the chlorine
residual to not less than 50 ppm.
(b) The chlorine solution in the tank must be
agitated thoroughly and allowed to contact the tank and any attached hoses for
not less than 30 minutes.
