6. HIGH-EFFICIENCY CLOTHES WASHING MACHINE FINANCIAL INCENTIVE PROGRAMS
A. Implementation
Implementation shall consist of at least the following actions:
- Until June 30, 2008, the water agency shall offer a
financial incentive, if cost effective, for the purchase of high-efficiency
clothes washing machines (HEWS) meeting a water factor value of 8.5 or less.
The water agency shall receive credit for HEWs with water factors greater
than 8.5 but not exceeding 9.5 until June 30, 2007.
- Any financial incentive offered shall be not less than the
marginal benefits of the water savings, reduced by the necessary expense of
administering the incentive program. Incentive levels shall be calculated by
using methods found in A Guide to Customer Incentives for Water Conservation
prepared by Barakat and Chamberlain for the CUWA, CUWCC, and US EPA, February 1994.
A water agency is not required to implement a financial incentive program if the
maximum cost-effective financial incentive is less than $50.
The Council shall begin to review this BMP before July 1, 2007. This review shall
determine appropriate agency implementation activities after June 30, 2008. The purpose of this
review is to revise this BMP to account for potential Federal and State standards, the
market share of HEWs with various water factors, further advances in washer efficiency,
funding partner activities, and consumer participation.
B. Implementation Schedule
- For Agencies signing the MOU prior to July 1, 2003, implementation shall commence no later than July 1, 2004.
- For Agencies signing the MOU or becoming subject to the MOU after
July 1, 2003, implementation shall commence no later than July 1 of the second year following the
year the agency signed or became subject to the MOU.
C. Coverage Requirements
Overview
The Council’s objective is to transform the clothes washer market by increasing sales of HEWs. The Council anticipates
this interim program will have a positive and long-lasting effect on the market share of HEWs; thus decreasing the future efforts
needed by the Council and its members to achieve water efficiency in this sector.
The goal for this BMP is to at least triple the market share of HEWs purchased for use inside residential dwelling units,
where no incentive program exists. For purposes of determining coverage requirements, the Council's estimates a non-incentive
market share of HEWs at 12% of all clothes washing machine sales (derived from year 2000 Energy Star data). The coverage requirements
are based upon the goal of increasing the market share of HEWs to thirty-six percent (36%) of all clothes washing machine sales.
Coverage Goal
The Council developed a Coverage Goal (CG) system to more easily determine coverage progress, and allow agencies to obtain
additional credit for promoting the purchase of ultra high efficiency machines with water factor values of 6.0 or less. The CG is
based on the total quantity of dwelling units (single-family and multi-family) in each agency's service territory. The Council chose
to use the quantity of both single-family and multi-family dwelling units because US Census data on in-home clothes washing machines
includes both types of dwelling units.
Agency determines its CG by the following calculation:
CG = Total Dwelling Units x 80% x 6.67% x 12% x 3 x 4
- Where:
- CG = Coverage Goal
- Dwelling Units = total SF and MF dwelling units in agency service territory
- 80% = percentage of all dwelling units with in-home clothes washers
- 6.67% = percentage of washers requiring replacement each year
- 12% = Average HEW market share when no incentives exist
- 3 = tripling non-incentive market share
- 4.0 = years of program activity from July 1, 2004 to June 30, 2008
Simplified Formula: CG = Total Dwelling Units x 0.0768
Agencies may request an adjusted CG where US Census data or other statistically valid
surveys prove that less than 80% of all dwelling units (single-family and multi-family) in
their service territory include a clothes washing machine. Agencies signing the MOU after
July 1, 2003, shall use a prorated CG based on implementation period of less than 2.5 years.
Coverage Points
Agency shall earn points towards its Coverage Goal for the purchase and installation of
HEWs in its service territory where agency provides a financial incentive. In efforts to transform
the market place towards ultra-high efficiency washers, agency may earn additional points for HEWs
with water factor values of 8.5 or less.
- Agency shall earn 1 point for each HEW incentive issued between July 1, 2004 and June 30, 2007,
which results in the purchase and installation of a HEW with a water factor value greater than
8.5 but not exceeding 9.5. No points shall be earned for these HEWs after June 30, 2007.
- Agency shall earn 2 points for each HEW incentive issued on or after July 1, 2004
resulting in the purchase and installation of a HEW with a water factor value greater than 6.0
but not exceeding 8.5.
- Agency shall earn 3 points for each HEW incentive issued on or after July 1, 2004
resulting in the purchase and installation of a HEW with a water factor value of 6.0 or less.
Past Credit Points
Agency shall have the option to receive points towards its Coverage Goal for past efforts
(efforts prior to July 1, 2004) by one of the following methods of agency’s choosing:
- Agencies shall earn points according to point scale described above in
"Coverage Points; 1, 2 and 3"for each HEW incentive issued before July 1, 2004,
resulting from agency incentive program, where agency has documentation of participation.
Agency shall not receive any credit for HEWs with water factors greater than 9.5..
Agencies shall not receive credit for any HEW sales or installations where the agency did not
materially and substantially participate in the incentive program.
OR
- Agencies shall earn 1 point for each HEW incentive issued before July 1, 2004, resulting
from agency incentive program, where agency has documentation of participation. Agencies shall
not receive credit for any HEW sales or installations where the agency did not materially and
substantially participate in the incentive program.
D. Requirements for Documenting BMP Implementation
- Agency shall provide documentation for all of the following items:
-
- a) The quantity of single-family and multi-family dwelling units in the agency service area and the calculated Coverage Goal.
- b) The quantity and value of financial incentives issued for HEWs with water factor values greater than 8.5, but not exceeding 9.5.
- c) The quantity and value of financial incentives issued HEWs with water factor values greater than 6.0 but not exceeding 8.5.
- d) The quantity and value of financial incentives issued for HEWs with water factors of 6.0 or less.
- e) Average or estimated administration and overhead costs to operate the program.
- f) To receive credit for past programs, agency shall provide: quantity and value of financial
incentives, water factor values and date of incentives issued for high-efficiency clothes washers installed before July 1, 2004.
- Agency shall retain records of each participant of the incentive program, including: name, address and telephone number of participant;
water account number of building or dwelling unit; make and model of HEW purchased; water factor value; dollar amount of the agency’s financial
incentive; dollar amount of program partner’s financial incentive (if applicable); and name of program partner(s).
E. Criteria to Determine BMP Implementation Status
Agency is offering a financial incentive to customers in its service territory for the purchase of high-efficiency clothes washing machines with
water factors of 9.5 or less until June 30, 2007 and with water factors of 8.5 or less until June 30, 2008, and agency is meeting the coverage requirement
as stated in this BMP.
Agency shall be considered on-track to meet its coverage requirements according to the following table:
| Implementation Status Schedule |
| Date | Percent of Points Earned Towards Coverage Goal |
| January 1, 2005 | 10% |
| July 1, 2005 | 30% |
| January 1, 2007 | 50% |
| July 1, 2007 | 67% |
| July 1, 2008 | 100% |
Agencies signing the MOU after July 1, 2003, shall have a prorated Implementation Status Schedule, based on implementation
period of less than 4.0 years.
F. Water Savings Assumptions
Gross water savings (gallons) from financial incentive programs that result in the purchase and installation of High Efficiency
Washing Machines with water factors equal to or less than 9.5 shall be calculated using the following formula:

- Where:
- N is the number of machines replaced.
i is the water factor, defined as less than 9.5 until June 30, 2007, and less than 8.5
until June 30, 2008.
- 13.3 is the Baseline WF for washers sold in 1994, as supplied to DOE by the Association of Home Appliance Manufacturers (AHAM).
- 14 yr. is the assumed average useful life of residential washers. (Based on information from the Bern Kansas study)
- 1,170 gallons/year is the average change in water use for a unit change in water factor. This value was developed by the California Energy Commission.
Net water savings (gallons) from financial incentive programs shall be calculated using the following formula:
NWS = GWS x (1 - FR),
where FR is the estimated rate of free ridership for the BMP 6 financial incentive program.
