ROONEY ASSISTANT CITY MANAGER SUBJECT: OPWA RESOLUTION NO 99 -01 ORDINANCE NO. 608 WATER RATE DECREASES FOR RURAL CUSTOMERS DATE: April 15, 1999 BACKGROUND: ' In June of 1998, staff was contacted by Mr. Witt, a resident of the Pleasant View addition, regarding the disparity between water rates charged to customers. Mr. Witt was specifically concerned about the difference in the rates for customers that resided within the corporate limits of Owasso as opposed to those ' that did not. Upon Mr. Witt's presentation to the OPWA, staff was directed to review water rates for those customers and possible adjustments. ' HISTORY: . Historically, the OPWA funded improvements to the water system through the utilization of property taxes. Because the OPWA could not apply a property tax on property outside of the corporate limits of Owasso, the city charged a higher usage rate for water. This insured that all users of the water system shared equally in the expense of the improvements; with the city customers having a lower usage rate and a property tax, and the rural customers having a higher rate and no property tax. In 1992, the OPWA began the process of earmarking additional revenues generated by water and sewer rates to fund capital improvement projects and their associated costs and/or in order to pay debt service on indebtedness relating to improvements. In 1993, the OPWA adopted a policy of a "phased in" program to equalize the rate difference between "in city" and "rural" customers. The program was based on the concept that the city no longer utilizes property taxes to fund water improvements. At that time, rate increases passed on to the OPWA from the City of Tulsa were no longer passed on to our rural customers. ' The current rate structure has rural customers paying 62.39% more than the "in- city" rate. PROPOSED RATE CHANGES: ' Staff conducted a review of the rates between the two es of customers over the last several months. . s While certainly it can be determined that a 62.39% rate difference between the rural rates and the city rates is not equitable, it was determined that a modest difference between the two rates should remain in order to encourage development within the city limits. For instance, if there is no rate difference between rural and city rates and development can "tap on" to city water and sewer, what encourages a developer to develop within the city limits? Without at least a slight benefit of a less expensive water rate, there is no incentive and the city loses all sales tax revenue from infrastructure materials to building materials. Several different rate scenarios were reviewed and staff is comfortable with a rate difference of 20% between the "city' customers and the "rural" customers. This represents an approximate 25% reduction in the current rural rate, and providing the customer uses less than 14,000 gallons of water per month, is slightly below the rate that Washington County Rural Water District #3 charges its customers. The rate decrease represents an annual impact to OPWA revenues of nearly $37,738, however the entire customer base is growing and the impact of $37,738 in 1999 is not what it would have been in 1993 and can be absorbed. ADDITIONAL COMMENTS: Unchanged by this rate decrease are all customers within the city, all those customers of Rural Water District #3 Rogers County acquired prior to November 1, 1993, and all sewer rates. City ordinance also provides for a 20% discount for low - income families who meet established criteria and these discounts would not be effected by this rate change. In order to clarify all water and sewer rates charged by the OPWA, all have been included within OPWA Resolution 99 -01. There is no change in sewer rates. RECOMMENDATION: Staff recommends OPWA adoption of Resolution 99 -01, establishing the water and sewer rates for all customers as set forth within Resolution 99 -01. Staff further recommends Council approval of Ordiannce No. 608. ATTACHMENTS: 1. Water Rate Spreadsheet 2. OPWA Resolution 99 -01 3.

Page 2 Request for Rental and Purchase of Wastewater Collection System Flow Monitoring Equipment FLOW MONITORING PROCESS: Flow monitoring is a technique commonly used to measure wastewater flow rates. Flow monitoring is primarily used to determine the total hydraulic load placed on a wastewater collection system and to detect point sources of inflow and /or infiltration. Inflow is surface water that flows into a wastewater collection system. Inflow is usually caused by holes in manhole covers and cross connections with stormwater systems. Infiltration refers to the ground water that has entered a collection system through defective pipes, pipe joints, connections or manhole walls. Preliminary flow monitoring conducted during phase one of the system evaluation will include: one (1) flow meter placed downstream of the El Rio Vista sub -basin and three (3) additional meters placed in downstream locations of the Ator Heights sub -basin (see Attachment). Flow data will be collected for a period of approximately sixty (60) days so that dry and wet weather conditions may be observed. In addition, a rain gauge will be installed at a central location within , the Ator Heights sub -basin so that flow data can be compared to rainfall times and amounts. The flow and rainfall data collected will be used to determine each of the sub - basin's flow , patterns (i.e., dry weather (base) flows, wet weather (infiltration) flows or storm event (inflows)). The flow pattern data will be tabulated and analyzed to determine the severity of the observed inflow and/or infiltration and pinpoint areas in need of improvement. EOUIPMENT OPTIONS: Staff began evaluating metering equipment options in January 1999. The equipment needed to conduct the study can be either purchased or rented. Purchasing the equipment is not a viable alternative due to acquisition, maintenance and up -grade costs. Rental will eliminate the need to provide equipment maintenance and up- grades as well as enabling the City an opportunity to utilize alternative equipment types, if desired, later in the study. Four (4) equipment suppliers were contacted and asked to provide purchase and rental quotes for metering equipment. The vendors are Badger Meter, ISCO, EPI and Alpha Supply. A listing of each quote is provided in the following table (see Table 1). ISCO, EPI and Alpha Supply indicated that the rental quotes for the metering equipment did not include the cost of the interfacing software package needed to recover the flow data. The software must be purchased separately. Furthermore, Badger Meter, ISCO and Alpha Supply indicated that a laptop computer is required for data retrieval and meter calibration and is not included in their rental quotations. The laptop computers must be purchased separately. Four (4) flow monitors and one (1) rain gauge will be needed to conduct the phase -one study.

Since we have no ' previous experience with Badger Meter, we requested a listing of companies that have either purchased or rented similar equipment within the last two (2) years. Included in the listing was the City of Claremore, which is currently under Consent Order by ODEQ for unpermitted wastewater bypasses. The City of Claremore had purchased a number of flow meters from Badger in 1997 for the purpose of flow monitoring its wastewater collection system. Based on this information, staff contacted representatives from Claremore and inquired into the performance and accuracy of the meters purchased from Badger Meter. Representatives from Claremore indicated that re- occurring problems were present while using the Badger meters. NData that was collected was non - continuous, as the meters would often record information, and then shut down due to low battery capacity. An additional problem encountered, was periodic fouling of the flow meter sensors. The flow meters would function by recording both depth of water and the velocity of the flow. The level sensor functioned correctly, but the velocity sensor fouled and recorded very low values for long periods of time. w. As a result of the problems encountered with the Badger meters, the City of Claremore a purchased flow - monitoring equipment from EPI. The Sigma meters provided by EPI have performed reliably, accurately and require little field maintenance. Page 4 Request for Rental and Purchase of Wastewater Collection System Flow Monitoring Equipment Based on City of Claremore experiences with Badger Meter, staff decided to investigate the capabilities of the Sigma flow meter (supplied by EPI). Discussions with representatives from EPI indicated that the monitoring equipment provided by Sigma will be simple to use, provide accurate data, require minimal maintenance and will be supported by factory, technical staff that can be contacted 24 hours a day / 7 days a week to answer questions. EPI is capable of supplying the needs for the City of Owasso flow - monitoring project and has submitted the second lowest quote for metering equipment (see Attachment). Staff recommends purchasing and renting metering equipment from EPI. FUNDING SOURCE: _ The FY 98 -99 Wastewater Collection Division Budget did not anticipate this expenditure. Adjustments in various line items can be accomplished. The division budget contains sufficient funds for the rental and purchase of the equipment. RECOMMENDATION: Staff recommends Trustee approval of 60 -day rental of four (4) flow meters, one (1) rain gauge and the purchase of an interface software package from EPI Inc of Tulsa, OK in the amount of $7,475.

Garnett, Suite I Tulsa, OK 74146 MEMORANDUM TO: HONORABLE CHAIR AND TRUSTEES OWASSO PUBLIC WORKS AUTHORITY FROM: F. ROBERT CAM JR., P.E. � ✓� PUBLIC WORKS DIRECTOR ' SUBJECT: SLUDGE HAULING ' DATE: April 14, 1999 IBACKGROUND: The existing City of Owasso wastewater treatment facility was constructed in 1986. Phase I improvements to meet changes in water quality criteria were completed in 1998. The plant improvements consisted primarily of construction of oxidation ditch aeration, external clarifiers, ' and additional sludge drying beds. The plant improvements were designed to treat an average daily flow of 2.15 million gallons per day (MGD). The treatment scheme (see Figure 1) allows untreated wastewater to flow into the oxidation ditch, where it combines with the bacterial mass growing in the basin to remove organic material. The organic material is used as food for the bacteria and the environment results in increased bacteria (solids) growth. The bacterial mass is then transported to the clarifiers, where the solids are allowed to settle. Solids in the clarifiers are pumped to the sludge drying beds to enable excess liquid to be removed from the solids prior to disposal in the landfill. Current average daily flow is approaching the original design capacity of the treatment plant and quantities of solids removed from the wastewater exceed that projected during design of the facility. As a result of the increased flow and solids produced, the sludge drying beds are full I and solids have been accumulating since March 1998 in the aeration basin and clarifiers (see Figure 2). In order to keep solids from being washed out of the clarifiers and into the plant effluent, operating personnel have attempted to control flow through the plant until the solids could be removed. To keep from exceeding permitted effluent discharge criteria solids levels in the clarifiers had to be reduced. It was originally estimated that removing 750,000 gallons of sludge should be able to get the plant under control. An additional 75,000 gallons per week was Iprojected that will need to be removed to keep accumulations from re- occurring ALTERNATIVES EVALUATED: Solids need to be removed from the treatment system to reduce the accumulation in the ' oxidation ditch and the clarifiers. Concentrated solids could be taken from the clarifiers for � I Page 2 Sludge Hauling removal from the plant. Various methods to dispose of the liquid solids was investigated by plant operating personnel. These methods included: Transporting in tank trucks to the landfill At the landfill, the liquid solids would be solidified and buried with hazardous waste materials. Costs included transportation, solidification and disposal. Transporting liquid sludge was quoted at $55 per 3,000 gallon load. Solidification was stated to cost approximately $0.10 per gallon. Total estimated cost for 750,000 gallons was $88,750. Contracting for land application Land application of liquid sludge is a common disposal practice. A disposal location would need to be permitted by a contract hauler, which could take considerable time. Costs of disposal were estimated to be as high as $0.05 per gallon. Total estimated cost for 750,000 gallons was $37,500. - Transfer sludge to stormwater holding basin _ Sludge could be piped to the plant stormwater holding basin and held until sludge processing equipment is installed in the next phase of construction. Costs would include dredging to return the sludge to the plant. Transporting in tank truck to City of Tulsa Northside Wastewater Treatment Plant Liquid sludge would be transported to Tulsa and disposed of in their sludge lagoon. The lagoon is scheduled to be cleaned and dried sludge material land applied in the Summer 1999. Costs included transportation and a pro -rated portion of the lagoon cleaning charge. Estimated total costs were projected to be $4,650 for transportation and approximately $15,000 at $0.02 per gallon for disposal. Based on the above alternatives, the most timely and cost - effective solution was to truck liquid sludge to the Tulsa Northside Plant. A verbal agreement was made with Tulsa for the disposal of 750,000 gallons of liquid sludge. The City of Owasso would also be requested to pay a pro -rated portion of the land application costs when Tulsa cleans the sludge lagoon this Summer. Based on previous disposal contracts, the City of Tulsa estimated the cleaning costs to be approximately $0.02 per gallon. PROJECTED HAULING COSTS: Sludge Technology, Inc., Muskogee, Oklahoma was selected as the less cost vendor for sludge hauling. Various other haulers were contacted and quotes for hauling received, but the trucking costs exceeded those stated by Sludge Technology. Sludge Technology could haul 6,000 gallon loads at a cost of $37.20 per load. The total 125 loads (750,000 gallons) were calculated to cost $4,650. This value did not exceed the $5,000 spending authorization limit of the City Manager, therefore, sludge trucking was initiated immediately on March 22, 1999. ' Page 3 Sludge Hauling ' ADDITIONAL HAULING REQUIRED: Following the initial hauling, plant operating personnel assessed the removal effectiveness. They determined that additional sludge removal is still required. Contact was made with City of Tulsa personnel and authorization for an additional amount of sludge disposal was verbally received. Approximately 12 — 6,000 gallon loads hauled once per week for 6 -8 weeks was authorized. The additional estimated sludge quantity could be 576,000 gallons at a hauling cost of an additional $3,571.20 (12 loads per week for 8 weeks at $37.20 per load). The total estimated cost of trucking liquid sludge is $8,221.20, which exceeds the City Manager spending authorization. In addition, the OPWA requirement for bidding purchases above $7,500 would be exceeded. 1 DECLARATION OF AN EMERGENCY: Removal of the sludge is imperative to successfully meeting plant effluent discharge criteria. Plant operating staff initiated sludge removal anticipating more positive results than actually r obtained. Continued sludge removal is needed to achieve adequate process control. To cease removal of the sludge at this time would be ineffective. ' Since operations staff are currently removing sludge, time constraints will not afford an ability to prepare specifications, advertise and award a bid. Quotes for transporting liquid sludge previously had been received. Therefore, staff is requesting Trustees declare an emergency and ' waive competitive bidding requirements. FUNDING SOURCE: Funds for this expenditure were not included in the FY98 -99 budget. Adjustments in various line ' items can be accomplished and the Division budget contains sufficient funding needed to accomplish the necessary trucking. The pro -rated cleaning expense for the city of Tulsa sludge lagoon will be included in the FY99 -00 budget. RECOMMENDATION: Staff recommends Trustees declare and emergency and waive competitive bidding requirements and authorize an expenditure in an amount not to exceed $9,000 for sludge hauling to Sludge ' Technology, Inc., Muskogee, Oklahoma.
