Water Division
WATER SUPPLY AND CERTIFICATION QUESTIONNAIRE
Standard Practice U-18-W
San Francisco, CA
February, 2007
A. PURPOSE AND SCOPE
1. The purpose of this document is to provide guidelines to regulated water utilities on properly preparing and filing the Water Supply and Certification Questionnaire (WSCQ) (see Attachment A) and to provide guidelines for Water Division engineers and analysts (Staff) to utilize in reviewing and processing the WSCQ. This document will guide Staff in the filing requirements for the WSCQ, a detailed review of a WSCQ, the preparation of an approval letter to the Department of Real Estate (DRE) (see Attachment B), and the rejection process for a WSCQ (see Attachment C).
B. BACKGROUND
2. While Public Utilities Code (P. U. Code) Section 1001 allows a utility to contiguously extend its service territory without Commission approval, General Order 103: Rules Governing Water Service Including Minimum Standards for Design and Construction (G.O. 103) applies to the extension. In order to assure compliance with G. O. 103, and to allow the Commission to generate an approval letter to DRE, the water utility must provide the Commission with information which supports its ability to meet these service standards. The WSCQ provides that information.
3. Regulated water utilities are required by G.O. 103 to design their water systems to deliver adequate, dependable, and safe water to all customers under maximum consumption conditions as well as to provide, for a sustained period of at least two hours, the fire flow requirements of the local fire protection agency (or, if no local agency exists, the minimum flow requirements outlined in G.O. 103). These design conditions must be met while maintaining normal operating pressures. In addition, G.O. 103 requires that the combined flow from all sources of supply and storage capacity be adequate for four consecutive days of maximum use.1
4. In order to verify that the system, after extension or additional customers, can meet these standards, the utility must submit a WSCQ to the Water Division for review and approval. The WSCQ allows Staff to verify that the system can meet the supply requirements of the current customers, the supply requirements of the anticipated customers, and the fire flow requirements of a maximum demand day. The burden of proof for providing this documentation rests with the utility.
5. Staff will normally encounter a WSCQ either through an advice letter requesting a DRE approval letter (e.g. a new subdivision being developed within the utility's service area) or with an advice letter requesting a contiguous service area extension (to extend its service area to incorporate a new customer/subdivision). Approval for a non-contiguous extension (a new service area more than 2000 feet from an existing service area) requires an application.
6. The Water Division has an agreement with the DRE to provide approval letters (referred to as a PUC confirmation letter) for subdivisions which demonstrate the ability to meet G.O. 103 design conditions. DRE's subdivision application (completed by the developer) requires information about the water supplier. If a water utility is regulated by the Commission, the developer must submit a PUC confirmation letter before DRE will approve the subdivision application.
7. G.O. 96-B, Rules Governing The Filing and Posting of Schedules of Rates, Rules, and Contracts Relating to Rates, Applicable to Gas, Electric, Telecommunications, Water, Sewer System, Pipeline and Heat Utilities, allows utilities to request Commission action when the request is not so complex as to require an application. The Water Division has historically allowed utilities to submit Water Supply Questionnaires (the precursor of the WSCQ) informally. However, as of April 5, 2000, policy now dictates that all WSCQs be submitted using the advice letter process.
C. WSCQ FILINGS GENERALLY
8. Since the processing time for a WSCQ either accompanying an advice letter requesting a PUC confirmation letter or with an advice letter requesting a modification of the service area maps is 30 days (Tier 2), the utility must allow adequate lead time for processing. The utility bears full responsibility in meeting any deadlines imposed by the developers of the subdivisions or DRE. Processing time will not be modified because a utility has failed to file in a timely fashion.
9. Sometimes Staff will encounter a WSCQ that has been submitted without an assigned DRE number. DRE will accept a PUC confirmation letter for subdivisions using only the subdivision name. Under this circumstance, Staff must verify with the utility that the correct subdivision name is included. By doing this, Staff is able to release the PUC confirmation letter, thus eliminating a duplicate WSCQ once the DRE number has been assigned.
10. DRE will only accept PUC confirmation letters which are no older than one year. DRE will require the developer to obtain a new PUC confirmation letter if a previous confirmation letter is older than one year. Likewise, the Water Division will only accept supporting documentation and figures in a WSCQ which are less than one year old.
11. Requesting a PUC Confirmation Letter. In the case where the utility is providing service to a new subdivision within its certificated service area and is requesting a PUC confirmation letter, Staff will review the WSCQ and verify that the G.O. 103 design requirements can be met. Typically, this advice letter is a simple filing and requires only verification that the subdivision is within the current certificated service area and that design requirements will be met.
12. Requesting a Service Area Extension. When the utility is extending its line, plant or service to include new customers or a subdivision, the advice letter will not only include the specific material required above, but will also include the following:
· a statement confirming the copy of the filing has been sent to the appropriate Local Agency Formation Commission,
· documentation demonstrating that the project for which the service area is being extended has at least preliminary approval of the local permitting agency. This is normally in the form of a letter from the local permitting agency,
· documentation, normally in the form of a letter, from the local fire protection entity having jurisdiction that it is satisfied with the water supply capability of the system planned for the new area,
· a fully completed and executed WSCQ, and
· documentation that the owner of any land who has not requested service has been informed that his/her property is being included in the utility's service area.
The need for this information results from the request of the Association of Local Agency Formation Commissions; the Commission's policy of limiting service area extensions to the land for which specific requests for service have been received; the need for assured fire flows in conformance with local requirements; the Commission's responsibility of certifying to the DRE that a subdivision receiving service from a regulated utility has an adequate water supply; and the due-process requirement of informing customers of actions that could affect water bills or other costs.
D. REVIEW OF A WSCQ
13. The WSCQ must clearly show that (1) the "requested area" is, or will be, entirely within the certified service area of the water utility, (2) the water utility has the ability to serve existing customers, the "requested area", and any projected growth during the development of the "requested area" (collectively referred to as the "entire system"), and (3) that an adequate fire flow exists for the "entire system". 2
14. Supporting data, calculations, and conclusions must be included in the WSCQ filing. Supporting data (flow quantities, fire flow test, letter from fire protection agency, number of customers, etc.) may not be older than 1 year from the date of the WSCQ. Calculations must be shown, where required. Any deviation from this format may cause delays in processing or possible rejection of the filing. Should Staff need additional information, Staff will contact the utility.
15. Review of the WSCQ should be done in two steps: (1) an administrative or cursory review and (2) a detailed review. The first review is to ensure all parts of the WSCQ are complete. Staff should immediately reject the WSCQ should any of the conditions outlined in the "Rejecting a WSQ" section below occur. The second step is a detailed review, with Staff verifying supporting data, calculations, and conclusions in the WSCQ. Staff will review each section of the WSCQ and should pay particular attention to the areas as noted below.
16. Rejecting A WSCQ. Staff shall automatically reject any filing under the following conditions:
a. any filing which is submitted with information older than one year,
b. failure to complete any requirements of the WSCQ,
c. failure to provide information, or
d. failure to verify the WSCQ.
17. The utility shall be sent a rejection letter indicating the reasons for rejection and be instructed to file a new advice letter correcting the deficiencies noted (see Attachment C).
18. Staff will continue to reject any subsequent refilings if any of the conditions listed above apply. It is the utility's responsibility to file correctly.
19. Reviewing a WSCQ.
a. Section A - WSCQ Processing Information Sheet. This section contains vital information which will aid Staff in processing the WSCQ. Staff should review it to ensure that all information is included. Staff should pay particular attention that the assigned DRE number is listed, whether a PUC confirmation letter (DRE letter) is required or not and that the correct subdivision name and tract number are included.
b. Section B - Water Source and Certification of "Entire System." This section provides information on the water supply requirements to meet the immediate demands of all customers during the time of maximum system usage. Staff should assure that all areas of this Section are filled in, including the main extension agreement information. A utility should not agree to serve a new subdivision without first having a main extension agreement in place. If the utility states that it does not have such an agreement, Staff should require a written explanation as to why the agreement has not been executed. This explanation should be attached to the WSCQ for future reference.
c. This section also provides information on the current water supply (including sources of supply and storage) available for the "entire system". It does not allow for planned additions, such as additional sources of supply or storage, to meet additional demand by the new customers or subdivisions. Planned additions are addressed in Section C (Minimum Two Hour Total Flow Conclusion For the "Requested Area") of the WSCQ.
d. All sources listed should be shown in gallons per minute and all information provided is subject to a one-year age limitation. Should a water supply source be another water agency, the utility must provide a letter from that agency confirming that the flow listed is available as stated in the WSCQ.
e. The total discharge capacity is determined as shown. It is the lesser of the (a) calculated rate of flow or (b) actual pipeline capacity available. The rate of flow available from storage is usually calculated by dividing the storage, in gallons, by 240 minutes. This figure represents the flow available from storage for four hours at the maximum demand. Four hours has been used under the assumption that most systems have two 2-hour periods of peak or near peak use on a maximum demand day and that usually it is not possible for the storage to be replenished during the time interval between these two peaks.
f. The actual pipeline capacity available is usually dictated by the size, length, and allowable pressure drop of pipeline facilities from storage, or is an actual number measured by the utility. Staff should bear in mind that oftentimes a utility will not know the actual pipeline capacity available, but should be able to calculate this figure. If the utility does not have the expertise to determine this number, then it should say so and utilize the calculated rate of flow as the discharge capacity.
g. Regardless of which figure is utilized for the discharge capacity, should there be less than one maximum day's storage available, the discharge rate should be multiplied by the ratio of the total storage (in gallons) to one maximum day's requirement (in gallons). This adjusted discharge rate would be used as the total discharge capacity available.
h. Staff should pay particular attention to the calculations of "QT," all calculations, and the indicated number of customers. Staff must also verify that a reasonable justification of the "c factor" is given. Generally, the utility will utilize the midpoint for the c factor. Regardless of what value is utilized, the utility must provide a reasonable justification for the c factor used.
i. The supply of water to be made available for a pressure system should be adequate to meet the requirements for the maximum hourly demand. The wells and other sources of supply must be capable of delivering continuously this maximum demand for least two hours. This requirement can usually be determined from the formula Q = n * c * f or taken directly from Chart 1 in G.O. 103. If additional demands of large users are known to exist these should be added to the total demand obtained from the formula or chart.
j. The maximum hourly demands of flat rate domestic water systems in permanent communities can be fairly accurately estimated at 1-1/2 times the average demand on the maximum day. The use of this method requires some means of recording the total use on the maximum day. The maximum hourly demand of metered domestic water systems in permanent communities is normally 1-3/4 to 2 times the average demand on the maximum day. The maximum hourly and daily demands of water systems in resort or seasonal communities can usually be estimated at about one half of the demands of a similar system for a permanent community under the same climatic conditions.
k. The system pumping capacity should usually be about 1-1/4 times the total water supply requirement in order to permit the pumps to restore water and pressure in the tanks at the same time as it is meeting the maximum system demand. This results in providing a reasonable safety factor because any centrifugal pump will deliver more water at the lower end of the pressure range than it will average within the pressure range.
l. As a general rule, a pressure system should not be designed to operate for more than one year with a single well facility. Any pressure system should be able to meet its average daily summertime demand when its largest pumping facility is out of service.
m. Section C - Minimum Two Hour Total Flow Conclusion for the "Requested Area." This section provides information on the minimum 2 hour flow required, either from the applicable fire protection agency or from the flow standards set by the Commission. In the case where there is no governing fire protection agency, the Commission's standards will govern. The utility must provide a written statement from the applicable fire protection agency outlining its requirements.
n. Staff should pay particular attention that the fire flow letter is attached, the average daily requirement is calculated correctly ("all existing customers" in this calculation does not include customers in the subdivision), all data submitted is no older than 1 year, and all calculations are correct.
o. The total water supply requirement is that flow which is required to meet the immediate demands of all customers during the time of maximum system usage and the applicable two hour fire flow requirement. The term "total water supply requirement" should not be confused with the actual water supply available for any particular water system. A water system having storage facilities which can store in excess of 10% of the maximum day's demand can normally meet its customers' demand with an available water supply which will be appreciably less than the total water supply requirement. Where the available water supply is very limited or seasonal, it will be necessary to provide storage facilities with a capacity large enough to store up to one or more maximum day's demand.
p. Section D - Supporting Documentation. Staff should pay particular attention that all maps are attached (system and subdivision), with all fire flow test(s), water sources, storage facilities, and pressure zones indicated. Verification should be made that all supporting data submitted be no older than 1 year.
q. The system maps and subdivision maps submitted under this section are not the same maps that the utility will submit as its tariff map (e.g. in the case of a service area extension), but are for use only in support of the WSQ.
r. Section E - Certification and Verification Sheet. This sheet should be signed and a title indicated, if applicable. If anything on this sheet is illegible, the utility must resubmit so that it is legible.
E. PROCESSING A WSCQ
20. As stated previously, all WSCQs are to be filed as advice letters. As such, they are subject to the statutory processing time. At the minimum, a 20 day protest period must be observed prior to the release of the PUC confirmation letter. Processing time will not be modified because a utility has failed to file in a timely fashion or has incorrectly filed the WSCQ.
21. Staff should, within 7 days of receipt of the filing, complete the administrative/cursory review and should either accept or reject the filing. If the filing is accepted, Staff should continue with the detailed review. If the filing is rejected, Staff should immediately return the filing to the utility with an accompanying rejection letter.
22. Staff should plan to spend no more than eight hours reviewing a properly submitted WSCQ and preparing a PUC confirmation letter. If the WSCQ is not submitted properly (e.g. not in the format requested), then Staff can require a longer period of time to review the WSQ. It is to the utility's advantage to properly submit a WSQ.
ATTACHMENT A
WSCQ AND INSTRUCTIONS
INSTRUCTIONS FOR COMPLETING THE
CALIFORNIA PUBLIC UTILITIES COMMISSION (CPUC)
WATER SOURCE AND CERTIFICATION QUESTIONNAIRE (WSCQ)
The WSCQ is to be completed by the water utility requesting to serve a particular area ("requested area") 3. The WSCQ is to be filed as a standard advice letter, in conjunction with a service area extension, if applicable4.
The advice letter process allows for a ministerial review while the WSCQ allows certification that the water utility has the ability to serve existing customers, the "requested area", and projected growth during the development of the "requested area" (collectively referred to as the "entire system"). The WSCQ must clearly show that all of the items below are met:
(1) The "requested area" is, or will be, either entirely within, or is contiguous5 to, the certificated service area of the water utility,
(2) An adequate supply of water is available to supply the "entire system" and each individual pressure zone within the system where the "requested area" is situated, 6
(3) An adequate fire flow is available to meet the fire flow requirements of the "requested area"7, and
(4) There is an adequate source of water to meet the "entire system" demand and the fire flow requirements if the water system is located in an adjudicated basin.
Supporting data, calculations, and conclusions are to be included in the WSCQ filing. All supporting data (flow quantities, fire flow test, letter from fire protection agency, number of customers, etc.) should be no older than 1 year from the date of the WSCQ certification and verification. Calculations must be shown, where required.
Please note that all areas in this WSCQ are to be completed, all attachments are to be provided, and the entire package must be certified and verified. Failure to do any of these will mean automatic rejection of the WSCQ and the filing.
The water utility should provide the information requested in the format as shown in this WSCQ. Should the CPUC analyst need additional information, he or she will contact the water utility. Once completed, the WSCQ is to be forwarded to:

TOTAL STORAGE CAPACITY |
SECTION B - WATER SOURCE AND CERTIFICATION OF "ENTIRE SYSTEM" (CONT.)
(15) Total discharge capacity is the lesser of (a) total storage capacity [from B(14)] divided by 240 minutes (4 hours) or (b) the discharge capacity that represents the use of storage during 4 hours of peak or near-peak demand where one or more maximum days' storage are available. If less than one maximum day's storage is available, the resulting rate should be reduced by multiplying it by the ratio of the total storage to one maximum day's requirements.
Show both methods of calculating total discharge capacity. Enter the lesser of these two figures in B(9).
(a) Total storage capacity [from B(14)] divided by 240 minutes:
(b) Discharge capacity that represents the use of storage during 4 hours of peak or near-peak demand where one or more maximum days' storage is available. If less than one maximum day's storage is available, the resulting rate should be reduced by multiplying it by the ratio of the total storage to one maximum day's requirements:

SECTION C - MINIMUM TWO HOUR TOTAL FLOW REQUIREMENT FOR THE "REQUESTED AREA"
G.O. No. 103 requires that fire flows are to be calculated on the basis of a residual pressure of 20 p.s.i.g. in the distribution system under flowing conditions.
(1) Fire Flow Required: gpm, as indicated in the attached letter [from Section D] dated , from the applicable fire protection agency.
(2) Average Daily Requirement (ADR) within the "requested area". Determined by calculating the average daily requirement per existing customer (in gpm) and multiplying it by the number of customer connections (lots) planned in the "requested area":
(No. of lots planned) x (Present annual consumption, in gallons)
(All existing customers) x (365 days) x (1440 minutes/day)
Indicate calculation:
ADR = ( ) x ( )
( ) x (365) x (1440)
= gpm

To Whom It May Concern:
This is in reference to Department of Real Estate File No. XXXXXXLA-FOO, the Dudley Do-Right Subdivision (Tract No. 1234) located in Los Angeles County. The Water Supply Questionnaire dated January 3, 2000, was completed by the Any Water Company.
From the data provided by the Any Water Company, it has been concluded by our staff that an adequate water supply is available to meet the anticipated requirements. In addition to domestic requirements, the utility will furnish fire protection to the developments in the minimum amount of 3,750 gallons per minute. This amount meets the fire protection requirements of the local fire protection agency.
We have no objection to the issuance of a final subdivision report.
