Impact of irrigation inefficiencies


Impact of customer leaks

-
10% waste 90 gallons a day or more via leaks


Fixing leaks in 5% of American homes can save 177
billion gallons of water annually


Consumers generally more concerned about the waste
of water than the bill impact of leaks

communications system


2009: 8% of the 39 million water
meters read remotely in the US
and Canada


2016: estimated to grow to 26%.

Growth driver: Water
conservation

36 U.S. states will face water
shortages by 2013, according to
government projections

Battery Life: A major difference between electric smart meters
and
gas or water meters

Water
striving for 20 year battery life

Strategies to conserve power


Highly efficient power management


Low power radios


Battery devices may not act as full nodes

in mesh smart meter networks

Challenges


Fewer facilities available for placement than other utilities


Transmission/Distribution infrastructure underground


Data need to be transmitted from indoor or pit water meters to the
collectors

Supports customer engagement strategies

METER DATA MANAGEMENT SYSTEMS

WHAT IS AN MDMS?

Scale of meter data with an AMI at
hourly interval

720
reads a month
(
for one meter
)


7.2
million reads
a month (
for 10,000 meters
)


State of California (10 million meters) 7.2 billion reads per month…

MDMS
provides a database repository and utility
-
specific
business logic


Automate and streamline the complex process of storing AMI water
meter data


Evaluate the quality of that water data and generate estimates of read
exceptions and gaps


Deliver that data in the appropriate format to utility water billing
system & to end users

The critical role of an
MDMS is
to pre

process granular interval
meter data at large volumes very
quickly

AMI/MDMS CASE STUDIES

City of Palm Desert, served by Coachella Valley Water District

Funded by the California Energy Commission PIER (Public
Interest Energy Research) Program

Purpose


Determine if water customers will shift water use out of peak period
(Southern California Edison peak period weekdays, noon
-
6pm, June
-
September)


Determine if on peak water savings will result in on peak electrical
savings by water agency

COACHELLA VALLEY WATER
DISTRICT
(CVWD) TIME OF USE STUDY

17

During study, approximately 30% of residences experienced
leaks (defined as continuous water flow for 24 hours)

28% of residential leaks required component repair or
replacement


Residential leaks totaled 165,000 gallons per month, 7% of total
participants water usage.

LEAK DETECTION

18

Customers that participated
reduced water consumption as
compared with control group

Large on
-
peak reduction and
smaller total reduction


CUSTOMER WATER
USAGE REDUCTIONS

19


Residential customers reduced peak use and also
reduced overall consumption


Reduced CVWDs peak period electricity demand by
about 6.5kW


No statistically significant shift in Commercial,
industrial and irrigation water peak or total usage;
however these groups benefited from the leak
detection


30% of business participants had leaks, wasting about 6% of their total
water use


About 15% of irrigation class experienced leaks, wasting about 3% of
total water use

STUDY
RESULTS

20

Service area is in New South Wales, Australia where the
government was encouraging electric smart meter systems.

Provides water and wastewater service to 1.8M properties.

Study was designed to look at synergies between water, electric
and gas AMI.

Initial study looked at benefit opportunities.

The study initiated further trials of smart metering including a
1,000 household collaborative study with Energy Australia.

Utility owned
-

Traditional approach


Complete utility control and management


Greatest impact on utility IT resources and infrastructure


Solutions allow for virtual machine implementation

Hosted solution


Third party (either MDMS vendor or other) provides dedicated utility
hardware in remote data center


Less impactful than utility owned but less control

System as a Service (SaaS)


No dedicated infrastructure

AMI & MDM Project Interaction


Properly aligning and coordinating the AMI and MDM projects is
essential

Mitigation Steps:


Synchronize MDM project schedule with AMI
schedule


which one
should go first


Involve AMI vendor(s) early at interface specification workshops


Understand the internal roles for project and get them involved in the
MDM early


GENERAL


LESSONS LEARNED

29

CIS & MDM Alignment


Properly coordinating and working through the MDM impacts to CIS is
essential

Mitigation Steps:


Identify development resources


Meet early to discuss impacts to CIS and associated
issues


Is a CIS replacement part of the landscape?


Ensure that CIS test/QA environments will be available for
MDM

GENERAL


LESSONS LEARNED

30

Dedicating staff for project work


Inadequate staffing from either the utility, SI, or MDM vendor can
cause delays


Need to identify utility staff knowledge transfer needs early


Need to monitor SI and make sure the ask/receive needed support
from MDM vendor

Mitigation Steps:


The ability to adjust staff and resources as problems emerge (
all
parties
)


Require SI/MDM to identify what staff is supporting what work


Develop detailed schedule identifying resourcing needs


Good communications and
coordination
