Water Conservation Plan
STAGE I -VOLUNTARY 25%REDUCTION IN TURF IRRIGATION
TRIGGER
During a period of substantial irrigation demand,when Expected Peak Demand reaches 90%
of Current Capacity or system demand is generating a high number of areas with low
pressure,or there are other indications that without wise usage of water,a shortage could
occur.
ANTICIPATED IMPACT
It is anticipated that Stage I will most likely be triggered during peak irrigation season.In a
typical year irrigation can account for as much as 40 MGD of demand on a peale day.If this
is the case,a 25%reduction in irrigation will result in a 10 MGD reduction in total demand.
At peak demand 10 MGD would be more than a 10%reduction.
GOAL
A 10%reduction in system demands as compared to Expected Peak Demand.
ACTION
Request a city wide 25%reduction in lawn irrigation.
Encourage customers to optimize their irrigation systems so water is not directed onto
impervious surfaces and turf is not overwatered.
Recommend customers irrigate on alternate days,by a system under which even numbered
addresses water only on even days of the month,and odd-numbered addresses water only on
odd-numbered days of the month.
Suspend City ofWaukees'hydrant flushing program except for water quality purposes.
The City will minimize high water use activities such as street sweeping and watering golf
course fairways.
Coordinate with wholesale customers to ensure they are relaying the same message.
ENFORCEMENT
There will be no enforcement at this stage.
STAGE II -VOLUNTARY 50%REDUCTION IN OUTDOOR WATER USE
(INCLUDING TURF IRRIGATION)
TRlGGER
During a period of substantial irrigation demand,after Stage I has been implemented and
failed to achieve an adequate reduction in consumption,when Expected Peak Demand
exceeds 90%of Current Capacity,or system demand continues to generate areas of low
pressure,OTthere are other indications that without further reductions in demand,a shortage
could occur.
ANTICIPATED IMPACT
It is anticipated that Stage II will most likely be triggered during the peak outdoor water use
season.In a typical year outdoor water use can account for as much as 50 MGD of demand
on a peak day.If this is the case,a 50%reduction in outdoor water use will result in a
25 MGD reduction in total demand.At peak demand 25 MGD would be more than a 25%
reduction.
GOAL
A 25%reduction in system demands as compared to Expected Peak Demand.
ACTION
Request customers further reduce water consumption by taking the following measures in
addition to those implemented in Stage I:
Request a city wide 50%reduction in outdoor water use.
Remind customers to optimize their irrigation systems so water is not directed onto
impervious surfaces and turf is not overwatered,
Reinforce the recommendation fOTcustomers to irrigate on alternate days.
Encourage wise use of water during outdoor activities including washing cars,playing in the
sprinkler,playing with water toys,and filling swinnning pools.
Encourage wise use of water indoors including identifying and repairing leaking fixtures,
washing only full loads in dishwashers and washing machines,shorter showers,etc.
Coordinate with wholesale customers to ensure they are relaying the same message.
Request that public agencies (City,County,or State)set an example by:
Closing recreational facilities with known water inefficiencies.
Suspend the operation of decorative fountains.
ENFORCEMENT
There will be no enforcement at this stage.
STAGE III -TURF IRRlGATION PROHIBITED AND NO USE OF AUTOMATIC
IRRlGATION SYSTEMS
TRIGGER
During a period of substantial irrigation demand,after Stage I and Stage II have been
implemented and failed to achieve an adequate reduction in consumption,when Expected
Peak:Demand exceeds 90%of Current Capacity,or system demand continues to generate
areas of low pressure,or there are other indications that without further reductions in
demand,a shortage could occur.
ANTICIPATED IMPACT
It is anticipated that Stage III will most likely be triggered during peak:irrigation season.In a
typical year irrigation,primarily turf irrigation,can account for as much as 40 MGD of
demand on a peak:day.If this is the case,prohibiting irrigation will result in a 40 MGD
reduction in total demand.At peak demand 40 MGD would be ahnost a 40%reduction.
GOAL
A 40%reduction in system demands as compared to Expected Peak Demand.
ACTION
Require customers to further reduce water consumption by suspending all turf irrigation and
the use of all automatic irrigation systems.This reduction is in addition to all steps
implemented in Stage I and Stage II.
ENFORCEMENT
Customers observed by the City of Waukee irrigating in violation of this policy will be
notified by a tag left at the property.If irrigation is not suspended within 48 hours,water
service will be terminated and the published termination fee will apply.Water service will
be restored only upon receipt,by the City of Waukee,of an undertaking by the customer that
the customer understands and will comply with the mandatory conservation measures.Any
subsequent violation will result in further termination of service.In addition the use of water
for irrigation in violation of this plan shall be deemed an unauthorized use of water and
"Charges for Breaking Seal or Tampering With Meter",as set forth in Section 203.6 ofthe
Waukee Municipal Code shall apply and must be paid before water service will be restored.
STAGE IV:WATER RATIONING
TRIGGER
During periods of substantial irrigation demand,after Stage I,Stage II,and Stage III have
been implemented and failed to achieve an adequate reduction in consumption,when
Expected Peak Demand exceeds 90%of Current Capacity,or system demand is generating a
high number of areas with low pressure,or there are other indications that without wise usage
of water,a shortage could occur.
Stage IV may also be invoked,without resort to Stages I through ill,if Expected Peak
Demand exceeds 90%of Current Capacity for any reason that cannot be addressed by the
measures contemplated by Stages I through III.
ANTICIPATED IMPACT
It is anticipated that Stage IV will only be triggered in the event of a significant and severe
water shortage,or other event,which severely reduces capacity relative to demand.In this
case a reduction in demand to the lowest level which will meet public health and safety
standards will be sought.
GOAL
A reduction in system demands as compared to Expected Peak Demand sufficient to allow
the Des Moines Water Works to meet public health and safety standards.
ACTION
Water rationing measures will be implemented and enforced by application of an Emergency
Water Shortage Rate.In order to implement such rate the City of Waukee shall set a target
level for demand consistent with its Current Capacity and shall use such target to establish a
"Rationing Factor"as defmed in this Plan.All customers will be asked to reduce their
consumption to a level at or below a "Stage IV Monthly Water Ration",and consumption
above such level will be charged at the Emergency Water Shortage Rate intended to strongly
discourage consumption above such level.
ENFORCEMENT
"Stage IV Monthly Water Ration"means for each customer the Typical Off-Peak
Consumption of such customer multiplied by an announced Rationing Factor."Typical Off-
Peak Consumption"shall be computed as ofthe date that Stage IV is invoked as the mean
monthly consumption of the customer for the inunediately preceding months of March,
April,and May.The Rationing Factor shall be a percentage,which may be above or below
100%,as announced by the City of Waukee and designed to effectively reduce consumption
to the level as required by the prevailing circumstances.
While Stage IV is in effect all water used beyond the Stage IV Monthly Water Ration for
each customer will be billed at the "Emergency Water Shortage Rate".The Emergency
Water Shortage Rate shall be four times the rate otherwise applicable to such customer.
Customers may appeal the Typical Off-Peak Consumption level determined for the customer
as the basis for the customer's bill as inaccurate or inequitable under the circumstances
applicable to the customer.Appeals must be submitted in writing and will be considered on a
case-by-case basis as provided uuder these Rules and Regulations.
