"At least once in every two years the City's consulting engineers hereinafter referred to in Section l5(d) of this ordinance, after making their examination and report on the condition, operation, and needs of the City's combined water and sewage system as provided in said Section l5(d), shall, by written instrument filed in the office of the City Clerk......, certify whether or not in their opinion, the moneys in the "Combined Water and Sewage System Extension and Bond Ret irement Account" are in excess of the amount reasonably required to be maintained in such account for extending, improving or enlarging the City's combined water and sewage system, and, if so, the amount of such excess." I I I Section 15 (d). "At least once in every two years the City will employ an independent consulting engineer or firm of consulting engineers having a reputation for knowledge, skill and experience in the con- struction and operation of municipal water and sewage systems and will cause such consulting engineer or engineers to make an examination and report on the condition and operation of the City's combined water and sewage system, such report to include recommendations as to any changes in such operation deemed desirable. Such report shall also make reference to any unusual or extraordinary items of maintenance and repair and any improvements or extensions that may be needed in the ensuing two-year period." I I I I The first such report was prepared in 1964 and this is the second report. I I I I I I 1 I I I 1961 BOND ISSUE I On 13 July 1961, the City of Salina, Kansas authorized the issuance of $3,600,000 in Revenue Bonds, the proceeds to be used to refund the principal amounts of two previous outstanding bond issues and "for the purpose of altering, improving, extending and enlarging the waterworks of said City......and for the purpose of altering, improving, extending and enlarging the sanitary sewer system of said City (said waterworks and said sanitary sewer system now having been combined into a combined water and sewage system of said City)". I I I The 1961 Bond Issue was supplemented by a $250,000 Federal grant to assist in the construction of improvements to the sewage treatment plant. The funds available for improvements to the water and sewerage system after refunding previous bond issues were as follows: I $3,600,000 250,000 I 1961 Bond Issue Federal Grant Total Funds Available for all Purposes $3,850,000 I Previous Bond Issues Refunding 1,182,000 Total Funds Available for Improvements $2,668,000 I I I I I I I I I 2 I I I 1961 BOND ISSUE EXPENDITURES I The following tabulation summarizes the expenditures for improvements to the combined water and sewerage system, such expenditures being solely from the original bond issue. All improvements are in accord- ance with recommendations of the City's Consulting Engineers and of the City Engineer's Office.

I I I I I I I I I I 3 I I I SYSTEM IMPROVEMENTS I While the closing of Schilling Air Force Base reduced the total number of accounts, the need for expanding water and sewerage service to newly developing commercial and industrial areas, the proposed incorporation of the former Air Base water system into the City's water system and the necessity to provide better service within the present system require a continued program of system improvements. A number of the improvements were recommended in earlier Consulting Engineers' studies and reports and some are required by more recent developments. I I I Among the earlier recommendations still to be implemented in the sewerage system are the Wayne Street Relief Main and the installation of variable speed pumping equipment in two major sewage pumping stations. A number of additional water main improvements were incorporated in a Consulting Engineers' report of 1963; however, the service area has expanded so rapidly in the last two years that it is recommended that another system analysis be undertaken before major water system improvements are considered for construction. I I I There is a continuing program of city participation in the construction of subdivision extensions of the water and sewerage system to pay the increased cost of enlarging mains as required by overall master planning.

Any additional expenditures must come from revenue income. I 4 I I I Another water main improvement which may be required in the near future and one which has not been programed is a reinforcement main on South Ohio Street from Republic Street to Cloud Street. It would be well to determine the size of this line in a overall system analysis. I I An additional study is required to determine the feasibility and the economics of disposing of that portion of the water softening plant sludge which is now being discharged into the Smoky Hill River and/or the sewerage system. I I I I I I I I I I I I I I 5 I I I REVENUE I Revenue is derived principally from a water rate schedule and a sewer service charge schedule. Both schedules are based on customer usage. The sewer service charge schedule was established at the time the water and sewerage departments were combined, there having been no previous direct charge for this service. The sewer service charge schedule has been revised on several occasions, primarily to establish equitable rates for special cases. The water rate schedule has remained unchanged. The excess of total revenue over operating expenditures (not including the bond issue debt service, reserve requirements and capital improvements), compared to the amount estimated by First Securities Company in their "1961 Financial Feasibility Report", is as follows: I I I I 1961 1962 1963 1964 1965 Actual Balance $411,625 $514,197 $456,503 $421,609 $345,014 Estimated by First Securities* $377 ,949 $377 ,949 $377 , 949 $377 ,949 $377 ,949 *25 Year Average I I I With exception of 1965, the actual balance has been in excess of that estimated and revenues appear to be adequate. It should be pointed out that the first several years of operation of the combined system were during near drought conditions and water sales were relatively high. I The closing of Schilling Air Force Base in 1964-1965 produced a marked effect upon the number of customers served by the municipal water and sewerage systems and upon the revenue derived. The Base closing was responsible for the loss of approximately 4,000 residents of the City and approximately 1,700 water and sewer accounts. The following chart indicates graphically the number of accounts and total revenue derived on a month-by-month basis. I I I City Ordinance No. 6546 requires that the City "maintain and collect rates, fees and charges for the use of or services rendered by its combined water and sewage system which will be sufficient to enable the City to have in each fiscal year a net operating income from such system in an amount that will be at least one hundred thirty-five percent (135%) of the amount required to be paid by the City in such year on account of both principal of and interest on the bonds herein authorized at the time outstanding." I I The following table indicates the Water and Sewer Department income position as compared to the requirement above: I I 6 I I I 1961 1962 1963 1964 1965 Net Operating Income $411,625 $514,197 $456,503 $421,609 $345,014 Principal and Interest Payments $107,242 $248,624 $234,270 $231,318 $228,965 Ratio, in percent * 207 195 182 151 I I I I *Not a full year of operation The required ratio of 135 percent has been exceeded through 1965.

The total transfer to the Extension and Bond Retirement Account has been $85,000. (This amount has increased to $90,893 due to interest received on the invested funds). I I I At the current rate of revenue production and with the program of planned expenditures, there will be no excess monies for the 1966-1967 period in the Extension and Bond Redemption account beyond the amount reasonably required to be maintained in such account for extending, improving or enlarging the City's combined water and sewerage system. I I In 1965 the reserve accounts "Bond Reserve" and "Depreciation and Emergency" reached the minimum amounts required by ordinance. Therefore, the $102,000 per year that has been required to be transferred from revenue to those accounts may now be transferred to the Extension and Bond Retirement account and be available for system improvements.

The survey concluded on-site inspections, examination of records and reports, and interviews with department personnel. I The combined water and sewerage department is well equipped to perform the required services to the community. Maintenance, in general, is routine in nature and is accomplished according to schedule and with reasonable dispatch. The purchase and operation of an extremely efficient sewer cleaning machine has enabled sewer maintenance personnel to undertake an extensive program of preventative maintenance. I I The combined water and sewerage department is exceptionally well managed and operated. Administrative personnel are knowledgeable and operate a business-like, efficient public utility. I I In the course of interviews with department personrlel, several matters were discussed which appear to merit consideration for further study and for action. I 1. In billing water accounts, a number of cases have arisen where a single owner may have two or more water meters serving a structure, a complex of buildings or several scattered buildings. The present ordinances governing the water consumption billing procedures do not stipulate a specific method for computing the charges for such cases. The provide the necessary administrative authority for computing these charges, it would appear that Section 30-119, Consumers, of the City Code should be revised, particularly the second definition where the term "in a common enclosure" can be interpreted in many different ways. It is recommended that the revision provide that: I I I a. The water consumption, as shown by multiple meters serving a single structure or a group of structures having single plumbing system, be combined for purposes of computing charges. I I b. All single meter installations be computed for billing on an individual basis. I 2. The present rate schedules for both water consumption and sewer service charges provide for accounts for those customers outside the corporate limits of the City. The present schedules require a double minimum and that the regular schedule of charges be increased by 25 percent when computing the billing for such accounts. On the basis of present detailed analyses in other communities, it has been determined that a more equitable schedule would be approximately twice the in-city rate. It is recommended that a detailed analysis be undertaken to determine the adequecy of present charges to customers outside the corporate limits. I I I 10 I I I I 3. Since 1963, a continuing study has been conducted of the water supply wells, all located within the urban area, to determine the extent of organic matter contained in the water obtained from these sources. The analytical method being used is the Carbon Chloroform Extraction of Dissolved Organics procedure as suggested by the Public Health Service. This procedure is relatively new and much is yet to be learned of the technique and the interpretation of the results. However, the results to date indicate that the existing well field is producing water with dissolved organic content in excess of the Public Health Service suggested limit for public water supplies. It is suggested that studies and surveillance be continued to determine the scope and the implications of dissolved organics in the well water supply. I I I I I I I I I I I I I I I 11 I I I CONCLUSIONS I The results of this study and examination indicate that, as of 31 December 1965, the funds in the Extension and Bond Retirement Account as shown in the Summary of Cash Funds Ac~ount table are not in excess of the amount reasonably required to be maintained in such account for extending, improving or enlarging the combined water and sewerage system of the City of Salina, Kansas. While the closing of Schilling Air Force Base materially reduced the total number of accounts, this situation is believed to be temporary, and no change in the rate structures appears to be desirable for the 1966-1967 period, The reserve accounts "Bond Reserve" and "Depreciation and Emergency" have reached the minimum limit set by ordinance, Thus, $102,000 per year previously required for transfer from revenue to those accounts may now be used for system improvements. I I I I The review of the condition and operation of the combined water and sewerage system indicates that the system is operated in a satisfactory manner and that the condition, in general, is good. However, recent and contemplated expansions of the water works system are so extensive that a review and updating of the system analysis should be performed to determine the need for and the location and size required of new feeder mains and other system improvements. I I I The following is a summary of recommendations and suggestions in regard to the operation of the combined water and sewerage system: 1. A review and updating of the water system analysis. I 2. A study to determine the feasibility and economics of disposing of water softening plant sludge. I 3. Consideration of adopting a specific method of computing charges for those accounts having multiple meter installation. I 4. A review of the charges assessed to those accounts outside the corporate limits. I 5. Continued study and surveillance of the amount of dissolved organics in the well water supply. I I I I 12 I
