PRIVATE WATER SUB-METER INFORMATION PACKAGE
|INTENTIONS OF THIS PACKAGE:||FMD SSC Info|
|To allow customers to be billed sewer service charges (SSCs) based upon private water sub-meter readings for commercial properties and five dwelling units and more on a single water meter.|
The information in this package will provide you with the following:
1. Background information about the program.
2. Points to consider about the benefits and responsibilities of private sub-metering.
3. The necessary steps to install a sub-meter.
4. Another alternative to calculate your discharge to the sewer.
1. BACKGROUND INFORMATION
The City Council has authorized a procedure that allows City of Los Angeles sewer system customers to use data from private water sub-meters in the calculation of their sewer service charges (SSC). The program is totally optional and the customer will bear all costs associated with it.
The program requires that the customer's plumbing be configured to separate the water distribution lines on the customer's property which drain to the sewer ("tributary lines") from those which do not drain to the sewer ("nontributary lines"). The private sub-meter may be installed on either the tributary or the nontributary line. Only one (1) sub-meter is allowed per DWP water meter in accordance with Los Angeles Municipal Code (LAMC) Sec. 64.41.03(g)3Aii. See the diagram on page four (4) for more information.
The present SSC system bases the SSC on a percentage of the volume of water delivered through the City meter and uses an estimating procedure to determine the nontributary percentage. The private sub-meter will substitute actual data for the estimate. Thus, the program should benefit many customers who use a greater than average volume of water for irrigation or other uses which are not tributary to the sewer.
Since the data from
the private sub-meter will provide the best available estimate of the
sewage flow generated from a customer’s property, the City's base rate
of $3.57 per hundred cubic feet (hcf) of sewage flow in effect on July
1, 2012, will be applied to the readings of a private sub-meter (on the
tributary line), or the difference between the readings of the
Department of Water and Power (DWP) meter and the private sub-meter on
the nontributary line, to calculate the customer’s SSC bill.
The $3.57 represents the City's cost to treat one hcf of sewage
This rate is the same as the current SSC rate of $3.57/hcf for
customers applied to 93% of the water delivered. This
includes an assumption about the percentage of water delivered that
(93% for most commercial customers which includes multiple dwellings of
five units or more). In other words, the $3.57 will be
applied to the volume of actual sewage discharge.
|2. IS THIS PROGRAM BENEFICIAL TO ME?||Top|
For those SSC customers that may be considering installing a private water sub-meter in order to decrease their SSC bill, the following will help you decide if this is the right solution for your property.
B. Is your irrigation plumbing totally separate from your inside plumbing? If not, you will have to rearrange your plumbing to separate the tributary and nontributary uses. There is an exception for hose bibbs, which may remain attached to the tributary plumbing, but no credit against the SSC will be given for nontribuary water discharged through hose bibbs.
C. The estimated cost for the private water sub-meter1 and its installation as depicted in our attached schematic is approximately $400 to $1100. This includes two hours of time for a qualified licensed and bonded plumber. The replumbing referred to in (B) above would cost extra.
D. THE PRIVATE SUB-METER PARTICIPANT HAS THE FOLLOWING RESPONSIBILITIES:
2. Since this is a private water sub-meter, you will be required to maintain it in good operating condition per the manufacturer's specifications.
3. You will be required to periodically calibrate the private sub-meter per manufacturer's specifications and recommendations and send the results to the City.
4. You must install the private water sub-meter in a location in front of the building that is readily accessible to the DWP meter readers.
5. The meter must be installed as a horizontal installation. See note 1 above and diagram on page 4.
6. If your sub-meter is malfunctioning and you do not take the necessary steps to correct it, you will be put back on the City's standard billing system. That system bills you SSC based upon 93% (commercial class) of delivered water.
7. If at anytime you decide to discontinue being charged based upon the private sub-meter readings and revert to the City's standard average sewage system, you will not be allowed back on the private water sub-meter billings until one year has elapsed.
8. You must sign
release form that indemnifies the City from any damages (physical or
financial) which may arise from the installation of the private water
sub-meter at your premises. See LAMC 64.41.03(g)3ii.
|3. HOW WOULD I GO ABOUT ACQUIRING A PRIVATE WATER SUB-METER?||Top|
B. Then, take the DBS permit to the DWP to purchase a private water sub-meter1 and its enclosure box (approximately $140 - $800 depending upon the size of the meter). The water sub-meter must be purchased from DWP if you want to qualify for this program. DWP will not read the meter if it is not purchased from them. Please contact DWP at 213 367-2130 to find the office nearest you.
C. After the private sub-meter has been installed, you will notify DBS that the sub-meter has been installed and is ready for inspection. If the DBS plumbing inspector finds that the tributary and nontributary lines have not been totally segregated (except for hose bibbs as explained on the diagram), additional plumbing work will be necessary and inspection cost incurred. Once the DBS plumbing inspector has approved the installation, DBS will notify DWP to begin reading your private water sub-meter and bill you under the new system.
D. You will receive your first DWP bill with the SSC based upon the private sub-meter readings after you have accrued one complete cycle of private water sub-meter read data (approximately 30 or 60 days) depending on the frequency of your current billing.
|4. REQUEST FOR SSC ADJUSTMENTS OR MORE INFORMATION||Top|
Financial Management Division (FMD) can do an investigation, upon written request, to compute an estimated percentage discharge for your property before any money is spent by you to install a private water sub-meter. FMD will require that the customer send a letter that states the basis on which you believe the property qualifies for an adjustment such as occupancy, irrigated area, water that goes into a product or cooling tower evaporation, etc. Also include a copy of the latest DWP bill or bills for the service address. The requests for an SSC adjustment must be in writing and sent to: Bureau of Sanitation, Commercial SSC, PO Box 79112, Los Angeles, CA 90079-0112 or faxed to: 213 485-2984 or 485-4269.
HOW CAN I GET MORE INFORMATION REGARDING THESE PROGRAMS?
If you have additional questions, please call the Bureau of Sanitation, SSC Hotline at 1 800 540-0952 or 213 473-4181.
