John Bock, Administration Manager of Utilities, appeared before the Board to review proposed changes in the Municipal Sewer Code. When a house is demolished with plans to rebuild a new house, sewer services have been lost during a demolition without a correct cutoff. The proposed ordinance changes will help the Utilities Department manage and control these services at demolition . The proposed ordinance changes will have Municipal Code 12-2-4: Private Sewers , Connections and Repairs read as follows: City Code 12-2-4: Private Sewers, Connections and Repairs. B. Old Private Sewers: The use of existing or aging cast iron, clay tile or concrete sewer service pipes will not be permitted at new buildings on properties where there has been a change of ownership 'tvithin the last twelve months . The old sewer service must be replaced from the building to the main with approved pipe. Owner/occupants of properties who desire to replace a building with the intent to occupy it themselves may seek a variance from the Water and Sewer Board if the existing pipe is found by Utilities Department inspectors to be in sound condition. Utilities Department inspectors may require all necessary tests to conclusively establish the condition of the existing sewer service pipe. Abandoned private sewers shall be plugged at the sewer main and at the user's expense upon discontinuance of service . The plug in the old private sewer must be inspected and approved and a plan review and inspection fee will be charged by the City. Existing sewer saddles or wye connections may be used for new sewer services if approved by Utilities Department inspectors. If an abandoned sewer service is not plugged at the main within 30 days, the City may perform the disconnection and may charge time and materials against the property either through the next regular quarterly water bill or by lien . • • • I Discussion ensued with Mr. Woodward and Mr. Clark regarding the intent of the change . It was recommended that, "within the last twelve months" be removed from the proposed ordinance change. The Board concurred. Mr. Bums moved; Mr. Clark seconded: Ayes: Nays: Members absent: Motion passed. To recommend Council approval of the proposed Municipal Code1changes to City I j ' Code 12-2-4 (B), Private $ewers, Connections and Repairs .. Bums, Clark, Cassidy, Wiggins, Woodward, Oakley, Habenicht None Moore, Higday 4 . POLICY CHANGES REGARDING WATER AND SEWER SERVICES AT BUILDING SCHEDULED FOR DEMOLITION. John Bock, Administration Manager of Utilities appeared to discuss changes to the existing policy regarding water and sewer services before, during and after the demolition of structures. He explained that sewer services are being lost in demolition, so no proper disconnection is assured . Water services are being disconnected at the curb stop and left live, sometimes for years. With the intent of controlling these services at demolition, the Utilities staff is recommending the following policy and Code changes: A. The Building Department will notify the Utilities Department when it receives an application, via the permit tracking system, for a demolition permit. The Utilities Department will notify the applicant of our water/sewer service cut off and inspection requirements. B . At the time of application, a "to be completed by'' date for the water and/or sewer will be determined for the water and/or sewer service cutoffs. The cut offs must be completed within 30 days after the "to be completed by" date. If the applicant does not amend the cutoff date, the Utilities Department may perform the cutoffs or hire a private contractor and charge time and materials against the property. C. New sewer service pipe may be extended to property line at the time of cutoff to avoid multiple alley cuts . The cutoff must be marked with a department-approved • • • / locating device . Existing saddle or wye connections may be used if approved by the , Utilities Department inspectors . If abandoned, sewer service lines must be cut off at the mam. D . New or replacement water or sewer taps at the main will not be allowed at new construction prior to disconnection of the previous water and sewer taps unless the Utilities Department has approved use of the existing pipes. . i i E. The Distribution/Collection Supervisor will be notified. of a~y #ater or sewer service line cutoffs . I ,, Mr. Habenicht moved; Mr. Cassidy seconded : Ayes : Nays: Members absent: Motion passed. To approve the policy changes recommended by the Utilities Department staff regarding water and sewer services for buildings scheduled for demolition. Burns, Clark, Cassidy, Wiggins , Woodward, Oakley, Habenicht None Moore, Higday 5. RAW WATER FLOW METER REPLACEMENT AND HATCH. Bill McCormick, Operations Superintendent of Utilities, appeared to discuss the raw water flow meter replacement and hatch at the Allen Filter Plant. The original 42" raw water magnetic flow meter tube has failed and there is no access for removal and replacement. It is necessary for the Allen Filter Plant to have an accurate raw water flow measurement for chemical dosing and pacing demands. Brown and Caldwell Engineers has recommended structural modifications to the existing building to provide access to remove and replace the 42" flow tube and modify the existing piping to create a straight run for a magnetic flow meter. Bids for the raw water flow meter replacement and access hatch were received and Brown and Caldwell recommended Glacier Construction as the lowest, acceptable bid at $30,800.00 . per their letter dated April 2, 2008 . I • Mr. Clark moved; • • Mr. Cassidy seconded: Ayes: Nays: Members absent: Motion passed. To approve the bid for the Allen Filter Plant raw water flow meter replacement and hatch to Glacier Construction in the amount of $30,800.00 as recommended by Brown and Caldwell. Ii Burns, Clark, Cassidy, W,iggins , Woodward, Oakley, Habenicht None Moore, Higday 6. TRANSFORMER REPLACEMENT PROJECT FOR THE ALLEN FILTER PLANT . Bill McCormick, Operations Superintendent of Utilities, appeared to discuss the transformer replacement project for the Allen Filter Plant. The original transformer was installed in 1952 by Public Service Company with a newer transformer installed in the 1980's. A secondary transformer and switch is critical during various events that create power outages from Xcel Energy. The existing transformer then becomes the backup transformer. Also, the anticipated UV disinfection system to be installed at the Allen Filter Plant in the next few years will increase the plant load, making a secondary transformer even more crucial. Because of a 35 to 37 week lead time, the transformer and switch was ordered in July, 2007. The Allen Plant is hoping to get the new transformer on line by the summer of 2008. Bids were received and the lowest acceptable bidder approved by Brown and Caldwell is Glaser Electric in the amount of $106 ,115.00. Mr. Burns moved; Mr. Wiggins seconded: To recommend Council approval of the bid for the installation of the transformer, switch and other improvements in the amount of $106, 115 . from Glaser Electric Company . • • • Ayes: Nays: Members absent: Motion passed. / Burns , Clark, Cassidy, Wiggins , Woodward, Oakley, Habenicht None Moore, Higday ll !. 7 . GRANULATED ACTIVATED CARBON (GAC) AT ALLEN FILTER PLANT . Bill McCormick appeared to discuss turbidity issues due to manganese on our GAC media. At the Allen Filter Plant, the granulated activated carbon was regenerated earlier this year for three filters. The GAC on these three filters have a manganese attachment to the media that is causing unacceptable turbidity when it passes through the GAC and is being oxidized in the clearwell by the chlorine disinfection process. The manganese is causing yellow water in the water distribution system , but the water is still within safe drinking water standards . Bill explained that the plant is trying to correct this condition by adding sulfuric acid to the water to oxidize the manganese out of the media and lower the manganese level to an acceptable level, as per instructions by the GAC supplier. The Allen Filter Plant is continuing this course of action and observing the outcome. If this does not produce the desired results, pre-chlorination will be tried. Ultimately, the GAC media may have to be replaced. 8. IMPACTS OF ANTIDEGRADATION AND USE PROTECTION. The Board received an Executive Summary from the Littleton/Englewood Wastewater Treatment Plant (LIE WWTP) regarding impacts of antidegradation on Segment 14 of the South Platte River. Stream segments are classified based on the level of water quality protection necessary for designated beneficial uses . The LIE WWTP discharges effluent to Segment 14 of the S. Platte River and is classified as "reviewable," whereas if no reasonable alternatives are available , degradation is allowed only if it is necessary to accommodate economic or social development. This may result in permit limitations more stringent than water quality standards. Under the antidegradation review , the LIE WWTP may have to meet stricter limits including additional constituents that have not been permitted in the past. This may require additional treatment processes to comply with the new standards, resulting in increased sewer rate. Attaining a use protection designation would result in permit • • • I limitations to meet water quality standards thereby avoiding additional costs associated with meeting antidegradation requirements. This issue was reviewed with Englewood City Council and there will be a joint meeting with Littleton City Council which is scheduled for April 24 , 2008. The Board adjourned at 6 :14 p.m. . ! i .. The next Englewood Water and Sewer Board will be held Tuesday, May 13, 2008 at 5:00 p.m. in the Community Development Conference Room. Respectfully submitted, Cathy Burrage Recording Secretary
