The Industrial Customer Class shall consist of those customers whose sewage contains wastewater from a product manufactured, processed or fabri- cated by the customer. The Monitored Group Class shall consist of those customers determined by the Director of the Waterworks Department to be producers of waste- water that is, in his judgment, abnormal sewage. lhe Commercial Customer Class shall consist of �hose customers which have three or more living - 1 - units served by a single water meter, or which have one or more businesses served by a single water meter. A"living unit" is defined as a residential unit providing complete, independent, living facilities for one family, including permanent provisions for living, sleeping, cooking, eating and sanitation. Abnormal Sewage. The term "abnormal sewage" shall mean any sewage having a suspended solids or B.O.D. content which is, in the judgment of the Director of the Waterworks Department, signifi- cantly in excess of, or below, that found in normal sewage, but is otherwise acceptable into the City of Fort Worth Sanitary Sewerage System. Normal Sewage. By the term "normal sewage" is meant sewage which when analyzed, shows by weight a daily average of not more than 260 mg/1 of suspended solids and not more than 170 mg/1 of B.O.D., and which is otherwise acceptable into the Fort Worth Sanitary Sewerage System. B.O.D. (denoting biochemical oxygen demand).

Within ninety (g0) days after the eifective date hereof, any person desiring to deposit or discharge, or who is now depositing or discharging industrial waste into any sanitary sewer in the city shall make application to the chief plumbing inspector ior a permit. Application forms will be furnished by the chief plumbing inspector on request. The chief Plumbing inspector shall refer all such applications to the director for his approval or disapproval. The director shall approve such applications and grant an industrial waste permit only when the evidence submitted by the applicant demon- strates that the waste or wastewater to be deposited by the applicant in the sanitary sewer will comply with all the regulations of this Code. (b) Structures required. Within one hundred eighty (180) days after the effective date hereof (January l, 1g70), any person discharging industrial waste into a sanitary sewer in the city shall construct a suitable control manhole, downstream from any treat- rnent or storage tanks or other approved works utilized by such person for pretreatment, such control manhole to be for the purpose of facilitating observations, - 17 - measurements and sampling of all waste created and discharged by such person. The control manhole shall be constructed at a location and in a manner approved by the director. The control manhole shall be con- structed and installed at the expense of the person discharging the waste, and it shall be maintained at the expense of such person at all times in a safe, acceptable and proper operating condition. (c) Disconnection. If any person, depositing or discharging industrial waste into the sanitary sewer fails to secure an industrial waste permit within the time prescribed herein or if any person allows or causes waste of unacceptable quality under the require- ments of this section of the Code to be discharged into any sanitary sewer in the city, the director is author- ized, if such person is using city water, to disconnect such person's service line from the city water system and/or the city sanitary sewer system and the same shall only be reconnected at the owner's expense. If such person does not use city water, the director is authorized to disconnect such person's service line from the city's sanitary sewer system and the same shall only be reconnected at the owner's expense. The director shall notify the occupant or user of the premises where the waste is generated twenty-four (24) hours before disconnecting the service line. No sani- tary sewer connection or water connection disconnected hereunder shall be reconnected until the condition causing the disconnection has been corrected. (d) Inspection. The inspectors, agents or repre- sentatives of the City of Fort Worth charged with the enforcement of this section of the Code shall be deemed to be periorming a governmental function for the benefit of the general public and neither the City of Fort Worth, the director nor the individual inspector, agent or representative shall ever be held liable for any loss or damage, whether real or asserted, caused or alleged to have been caused as a result of the per- formance of such governmental function. The owners or occupants of premises where industrial waste is created or discharged into the sanitary sewer shall allow the director, his inspectors, agents or representatives free access at all reasonable times to all parts of such premises for the purpose of inspection or sampling or the performance of any of their duties hereunder, and the failure or refusal of such owners or occupants to comply with this provision shall be grounds for the disconnection of water and/or sewer service. (e) Measurement of flow. The volume of flow used in computing abnormal sewage surcharges shall be based upon metered water consumption as shown in the records - 18 - of ineter readings maintained by the Fort Worth Water Department. In the event that a person discharging waste into the city's sanitary sewer system produces evidence to the director demonstrating that a sub- stantial portion of the to�al amount oi water used for all purposes does not reach the city's sewer system, an estimated percentage of total water consumption to be used in computing charges may be established by the director. Any person discharging industrial waste into the sanitary sewers of the city-who procures any part or all of his water supply from sources other than the Fort Worth Water Department, all or part of which is discharged into the sanitary sewer, shall install and maintain at his expense water meters of the type approved by the director for the purpose of determining the proper volume of flow to be used in computing sewer service charges. Such meters shall be read monthly and tested for accuracy when deemed necessary by the direc- tor. Where it can be shown to the satisfaction of the director that a substantial portion of the water as measured by the aforesaid meter, or meters, does not enter the sanitary sewer system of the city, then the director may require or permit the installation of additional meters at the owner's expense in such manner as to measure the quantity of water actually entering the said sanitary sewerage system from the lot, parcel of land, building or premises of such owner or occupant, and the quantity of water used to deter- mine the sewer service charge may be the quantity of water actually entering the sewerage system as so determined, if the director so elects. If the director finds that it is not practicable to measure the quantity or quality of waste by the aforesaid meters or monitoring devices, he shall determine the quantity or quality of the waste in any manner or method he may find practicable in order to arrive at the percentage of water entering the sanitary sewerage system of the city and/or the quality of the sewage to be used to determine the sewer service charge. (f) Determining the charac'cer and concentration of waste. The industrial waste discharged or deposited into the sanitary sewers shall be subject to periodic inspection and sampling as often as may be deemed necessary by the director. Samples shall be collected in such manner as to be representative of the character and concentration of the waste under operational con- ditions. The laboratory methods used in the examina- tion of said waste shall be those set for'ch in the - 19 - Standard Methods. The determination of the character and concentration of industrial waste shall be made by the director at such times and on such schedules as may be established by the director. Should an owner or occupant discharging industrial waste to the sanitary sewers desire a determination of the quality of such industrial waste be made at some time other than that scheduled by the director, such special determination may be made by the director at the expense of the owner or occupant discharging the waste. (4) PRETREATMENT (a) Pretreatment. Owners or occupants, or any other person, generating waste prohibited from dis- charge into public sewers by the foregoing shall pretreat or otherwise dispose of such prohibited waste so as to make the waste discharged to the public sewer acceptable under the standards established in this chapter. (b) Plan, specifications. It shall be the responsibility of any person, owner or occupant dis- charging waste into the sanitary sewerage system of the city to furnish the director with drawings or plans and specifications in such detail as he may require to determine if the pretreatment structure planned by such person, or in use by such person, is suitable for the purpose intended. However, the approval of such plans by the director will in no way relieve such person of the responsibility for modifying the structure once constructed as necessary to produce an effluent accep- table to the director under the terms of this section." - 20 - SECTION 4. That this ordinance shall repeal every prior ordinance and provision of the Fort Worth City Code in conflict here- with but only insofar as any portion of such prior ordinance or provision shall be in conflict, and as to all other ordi- nances or provisions of the Fort Worth City Code not in direct conflict herewith, this ordinance shall be and is hereby made cumulative. - 21 - , ; � �_ �`�� ' � � � , � _ SECTION 5.

Vt as noted that, under the recommended water rate schedule, the present combined wate�` and wastewater service rate would be eliminated as it does not provide a basis fo� the separate accounting of water and wastewater related bi?�ing proceeds, Another reason for eliminat�ng the combined rate �s that dissimslar`�ties between the cu5tomer service characterlstics and costs of the wate� and wastewater utilities make it difficult to design and admin�ste.r a practical common rate for the two utilities. �t �s recommended that, under the proposed rate, charges be computed in the same manner for all customers, based on the total water use passing through each metered service connection, irrespective of the number of living or commercial units subsequently served through the connection. Proposed Raw Water Rate The consultants propose that raw water prices remain at the same rate of $0.16 per 1,000 gallons for first million gallons of monthly use and $0.13 per 1,000 gallons for a11 additional monthly raw water used as currently an effecto Proposed Private Fire Protection Water Service Charge Serv�ce Connection 4-inch 6��nch 8-inch 10=inch Monthly Charge �7hese are the same as at p�`esent except for the 10-incho) Effect on Residen�ial Customer After �hese new rates become effective, all customers who are served by both wate� and wastewater utillties will receive a statement which separately identifies charges for water and for wastewater service. The statement will also have the �efuse collection and disposal charge which is collected for the Public Works Department shown separately, Example of Wa�er Charge A resident�al customer with a 3/4minch meter uses 1,000 cubic feet of water �n a month� The water part of the bill will be computed as follows: Se�v�ce Charge $1.00 lo ccf x So.46 4.60 TOTAL $5.60 NUMBER � WATER � WASTEWATER RATE STUDIES PAGE �ATE REFERENCE SUBJECT: ] 2 of � S 6i2tf76 G-3088 AND PROPOSED RATE iNCREASES � --- �onc�us�ons Attachment 2P Column 2 illustrates that the existing rates will not yield xhe �evenue �equired in Column 1 by a def►cii of over $1�300,000, The �'P�oposed Rate" schedule will yield revenue as shown in Column 3. �'he �even�e under "P�oposed Rates" as percent of cost of service shown in Column 4 indicates that �esidential customers will not completely pay their cost of service; that commercial class will pay slightly more; and that +ndustry will be paying at cost of service rates� The revenue under "Proposed Rates" as a percent of revenue under existing !`ates rndacates the percent increase each customer class will pay under the pi�oposed new �ate� �t should be pointed out that the proposed increase for an individual customer w�th�n a customer class will vary considerably between customers, The proposed water rates are dPsigned to work toward a true cost of service approach to �ates, but withou} unduly burdening any existing group of cusitomers� I� is antscipated that in future years it will be possible to adjust �he �ate schedule to even mo►'e closely meet a cost of service st�ucture, Compar�son of Proposed Rates with Other Cities Wate� and sanEtary sewer charges for 1,000 cubic feet (7,500 gallons) under �he proposed +~ates effective October 1, 1976, have been compared (Attachment 3) w�th s�milar charges for customers in Arlington, Austin, Dallas, Denver, Houston, Ok�ahoma City, San Antonio, Tulsa and Amarillo. The rates are compared (Attachment 4) with similar charges for customers in �973 and 1g76 fof San Antonio, Houston, Fort Worth, Dallas, Oklahoma City and Austin� Fort Worth's rate increase is less than any of these citiese i"t should be noted that San Antonio and Amarillo sti]1 rely primarily on we1� wate� which �s much less expensive to produce and treat than a surface supply. Rate Adjustment to Customer C�ties The water rate for the suburban customer cities wi]1 be adjusted for a fi�e year per�od beginning October 1978� The wastewater rate is being adjusted for most of the cities on an annual basis; but those who chose to stay with the f�ve year period will be adjusted in 1978.

To these agencies such action can demonstrate a trend which indicates an inadequate utility rate structure which uses its reserves to meet operating, maintenance, and debt service. It is possible that such a procedure will lower the grade of the revenue bonds, if done consistently. The City staff has recognized this procedure as a step to keep the reserves at a minimum safe level while at the same time attempting to operate with the lowest possible ratese . Once these reserves are depleted, the next rate adjustment must be large enough to off�set the revenues that have been provided by using reserves in addetion to any increases that will be necessary because of inflation or new government regulations. Effective Date of Proposed Increase Environmental Protection Agency regulations 35.935-13�a) requires that the Regional Administrator not pay more than 50% of the Federal share of any Step 3 Project unless the grantee has submitted evidence of timely development of its system of user charges and industrial cost recovery. It is estimated that the City will reach 50% about October 1976. ft is proposed that the ordinance adopting the proposed rate schedules be effective with the October 1, 1976 billing, which is consistent with past practice and corresponds to the City's fiscal year start datea The entire data processing system for water and sewer operations must be rewritten to accomodate these new changesa To have this system operational by October 1, 1g76, will require at least 90 days for all programs to be rewritten. Significant work on the programs can not be initiated until the Council has adopted new rate schedules. � � � v � > � � b p� .� c� O O o O w+-� � r- M M Ol � �, � O'� N N M M M Cj ,�„ � r r N N r- f�0 � � U � (/] �� O � � E-�+ „/ O �F.4 C7 p" v �.w.� � � •� ° '� �� :�°' a� � o m o � ax ��v o� rn o o rn o o W � y„ r r r � W y a o aQ � V W� o 0 0 0 0 L1 0 0 0 0 0 L� � o 0 0 0 0 aW � � a p d- � co � cD W� r M lfl CO � , �� N 00 I.f) I.f� r w �� - r— r 00 r-I 4 > � ; �. z Q „ a� W '� ,ik ��"„ H � � Q � r� � y O O O O O � "" W y N�' n.r,�, � O O O O O Q (y�,j �-" � � �'" • �S �`i r t� M l0 00 �'i � , � W tt') d' N l0 00 E-+ � � � M r- 1.!') � o � �� O C� O O O O O ,� �� ,,,U„ O O O O O ��1 `� � O�� 1� L[) 00 O O lfl r (� 1� Ol � U a V� N 00 t.t) 1� r � �f', d' r r CO Z � O o Q o � � � � (� r e- �r !LS � Z3 � ►�i y� -I-t •r •r N O � � � U S- S- v O �r � � •r ld � N � "t7 � +� U � U f-�i � f-- � � .-�� r N M d' � Q� W Q � l0 CO 6� O M O l0 � � l� O M O M � �l � 0 � o r r- r- r r- t� r' al d' N M r- d' N lfl 00 � O O cfi O � p � M O d' O � r � r- r 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 N P P �1 P d- pp lp M � N M tp M N d" I� � M pp ol d- N A .. ^ l0 N r' r r r r 0 0 0 0 0 0 0 0 0 0 0 0 0 0 M �fi � d' d � � 1� a1 N � w e. n e. s.
