Subject: REVISED EQUIVALENT DWELLIPJG UNIT (EDU) DEFINITION
Statement of the Matter
Pursuant to the City Council's request of April 18, 1977, the staff has reviewed the existing EDU definition and has developed an interim ordinance revision with
a new definition which is more realistic and which is patterned after criteria
used by other agencies.
The present ordinance uses "units" rather than EDU in determining the amount of
connection fees and sewer service charges. as "units" and counts only water closets and urinals in business and commercial buildings as "units." The new EDU definition will eliminate the inequities in
the present ordinance.
It also recognizes all dwelling units
The proposed new definition of EDU will require two. additions, one minor amend-
ment, and the repeal of one small section of the Carlsbad Municipal Code. This
is shown on Exhibit "B". .. .

SUBJECT: SEWER CONNECTIONS; DETERMINATION OF "EQUIVALENT DWELLING UNIT"
The existing sewer moratori urn has pointed up several probl ems in admi ni s teri ng Title 13 (Sewers) of the Municipal Code. The shortage of a comnodity (sewer plant capacity) which was not previously considered a constraint, causes us to consider how to best manage this important public facility. we need a method of insuring that capacity (and hence the ability to develop) goes where it best meets the community needs and where it is most efficiently used.
It becomes apparent
Staff is researching how other communities have addressed this problem. are a number of potential methods under analysis and, as with any management system, the more complex the system, the greater is the effort required to administer it. concerning any proposed sewer management system, would discourage a complex system with its attendant bureaucracy unless it can be established that it pro- vided the best cost-benefit return to the people of Carlsbad.
There
Staff is of the opinion that the Council, in its policy decision
While we are seeking comprehensive solutions to these major issues, we face the need to resolve an imnediate problem. What is an "EDU" and how is it determined? The answers could range from considering each physical tie-in to the system as an EDU, regardless of its flow, to requiring a detailed, updated analysis of each use of each building tied into the system. The first is obviously an over- simplification while the latter may require more effort to administer than should be required when considering the benefit.
The ordinance proposed by staff is offered with the knowledge that the inaccuracies inherent in averaging flows by class of use is offset by the ability to administer the system within our present framework. Provision is also made to deal with that one application which does not fit in with the other 99% that can be averaged
WHAT IS IN THE CODE AND HOW IS IT ADMINISTERED NOW?
To understand where we are now we should know where we came from. pre-incorporation, pre-Encina Water Pollution Control Facility days, sewage in "the town" was collected and discharged into a comnunity "septic tank" which then discharged to the Buena Vista Lagoon. concerned about who connected up. There was no sewer service charge, as such, since the system was operated by a sewer district which was funded from assess- ments based on property valuation.

MEMO to PWA Re: EDU -2- April 26, 1978
In the early days of Cityhood, folklore has it that when the City took over the district's functions a sewer service charge was thought to be a good idea to finance the operation of the system. A monthly sewer service fee was established per "unit." This "unit" is still in our existing SEWER SERVICE CHARGES Ordinance (13.12.010(3). Basically, - each residential unit (whether a house, or hotel room, etc.) was considered a "unit." closets and each urinal in a business or commercial building shall constitute a 'unit' .I'
In addition, 13.12.010(3)(F) says, "Each water
When, in addition to the sewer service charge, the City established a sewer con- nection charge, the ordinance required the appropriate sewer connection fee for each "living unit."
In 1968 an administrative directive (see attached) provided that a "livin unit" for other than residential was indeed the "unit" (water closet and urinal! that was used in the sewer service ordinance.
Since 1968, therefore, each nonresidential project which connected to the pub1 ic sewer system was charged a sewer connection fee based on the number of water closets/urinals in the structure. bears no relationship to the number of water closets. The most famous of all is the Burroughs Printed Circuit Manufacturing Plant which has 39 water closets yet generates the equivalent of 1100 - 1300+ "living units." laundromats, hospitals and clinics, produce and meat markets, and many industrial process businesses are high sewage generators and sewage flow has little or no relationship to such criteria as number of water closets, employees, or size of structure .
There are many instances where sewage flow
Full service restaurants,
Conversely, there are some projects with a relatively high number of water closets yet low sewage flow. each subspace has its own "convenience" restroom facilities (high ratio of water closets to employees).
An example is a luxury office building, or complex, where
Rather than wait for a more exhaustive analysis of the sewer code, staff is recommending a limited code amendment at this time.
