(Ordinance 1113.1 adopted 12/3/12; 2004 Code, sec. 13.861; Ordinance 1270 adopted 3/21/19)
(a) The city receives groundwater from seven (7) water wells that draw
water from the Hickory Aquifer and an expected future surface water
source from Brady Lake Reservoir. These two (2) water supply sources
provide redundancy for the city to ensure water is treated and delivered
in case one of the supplies fails to provide adequate volumes of either
groundwater or raw surface water. In spite of this redundancy, the
city must be prepared to respond to any emergency water supply situation.
It must also be prepared to respond to other emergency conditions
occurring in the city’s system.
(b) Four (4) threshold levels have been identified for triggering various
responses to water supply emergencies. These trigger conditions and
corresponding emergency response measures are summarized in attachment
D to Ordinance 1270.
(1) Stage 1 triggers - Customer awareness.
(A) Water customers are requested to voluntarily limit the use of water
for nonessential purposes and to practice water conservation.
(B) Stage 1 will begin: Every April 1st, the city will mail a public
announcement to its customers.
