WATER/WASTEWATER TASK FORCE MEETING August 12, 1999 11:30 a.m. - 1:30 p.m. Civic Center, Room 325
Citizens in attendance included Ed Gerding (Oregon Cherry Growers), Mark Fields (Suburban East Salem Water District), David Higgins, and others. Staff present included Frank Mauldin (Public Works Director), Tim Gerling (Assistant Public Works Director), Diane Taniguchi-Dennis (Wastewater Services Manager), Paul Eckley (Chief Utilities Engineer), Jack Merritt (Assistant Finance Director), Pat Dodge (Management Analyst II), Karl Goertzen (City Engineer), Rolland Baxter (Operations Services Manager), Randy Pecor (Wastewater Collection Superintendent), Ken Roley (Facilities Engineer), Jim Long, (Housing Rehab Project Coordinator, Community Development), John Russell (Redevelopment Program Supervisor, Community Development). It was announced at this time that Diane Taniguchi-Dennis, Assistant Public Works Director, is now Public Works staff liaison for this Task Force (replacing Floyd Collins as liaison). Also mentioned - new binders are available at this time. 3) CITIZEN INPUT None at this time. 4) MINUTES Minutes from June 10, 1999, meeting were approved unanimously as written. 5) COSA - FINANCIAL FEASIBILITY STUDY UPDATE Jack Merritt, Assistant Director of Finance, gave a brief update. There is a consultant meeting scheduled August 25 for sharing/incorporation preliminary results of the financial feasibility study that CH2M-Hill has been working on and following that will be incorporating the results into the COSA work and the rate design work. At that point, information will probably be brought back to the Task Force at the October meeting. 6) NATURAL TREATMENT SYSTEM DEMONSTRATION PROJECT UPDATE Diane Taniguchi-Dennis was introduced to present an update on the Natural Treatment System Demonstration Project. She reviewed the history of the project. The goal is to complete the feasibility study with the environmental assessment and submit it to the Bureau of Reclamation for review by December 1999 or January 2000. Right now, the demonstration project conceptual plan is being created and then will be going through a review with a panel of technical experts on Natural Treatment Systems. 6) SEWER LATERAL POLICY ISSUE Diane Taniguchi-Dennis presented Discussion Paper #3 on Sewer Lateral Replacement Policy as provided in the handout material and covered in the verbal presentation. She presented a summary of the previous discussions as well as new material including: Sewer R/R Program Focus; Refining the Approach (Identification and timing of Sewer Lateral R/R requirements); Refinement of Replacement Responsibility Alternatives; Preliminary Cost Comparison of Alternatives; Items for September 1999 meeting. The tentative schedule planned is for a draft policy development to be brought back to the Task Force in October 1999 with a more detailed report to read. We will look at targeting to move to a final Task Force policy recommendation in November 1999, but based upon need for public input, this schedule may change. The discussion of the Sewer R/R Program included the five elements of the Perpetual Life and I/I Reduction Program: A. Replacement of Aged Sewers; B. Replacement of Prematurely Failed Sewer Mains; C. Street Pavement Restoration/Resurfacing Avoidance; D. Positive Protection Program; E. Sewer Lateral Replacement Program. Also covered was the Sanitary Sewer Overflow Control Program which is required under the Mutual Agreement and Order and Waste Discharge Permit. Replacement responsibility alternatives included full private responsibility, joint responsibility, and enhanced existing responsibility. A summary of each of these alternatives was given, showing where responsibility lies for each (City vs. Homeowner). A clarification is needed on how the current policy deals with individual sewer lateral failures that are reported. They come into the City in many different ways. Generally, it is a complaint of a sink hole or standing water on private property or in the street. The current policy for these individual failures is that the homeowner is responsible for the repair or replacement all the way to the sewer main in the street. A homeowner typically wants to do a sewer lateral repair as opposed to replacing the full sewer lateral because of the costs involved. Therefore, if the utility inspectors find that the issue is on the private property, the homeowner will typically repair the lateral. If it is a sinkhole in the street, the homeowners have a difficult time accepting the responsibility to repair the sewer lateral because the problem is in the street. In the case of when an orangeberg pipe sewer lateral fails, the entire lateral must be replaced. The homeowner is responsible for the replacement all the way from the house to the street. There are two approaches to sewer lateral replacement: The Sewer Main R/R Approach where sewer laterals are replaced in conjunction with sewer main R/R projects. In the enhanced approach, multiple sewer lateral only projects would be grouped together as part of the CIP program. You also have to deal with sewer repair/replacement permit process where there are the individual sewer lateral failures. Orangeberg pipe is an example of this. This is as compared to the Home Sales Approach. In general, this approach uses an inspection upon home sale or home listing and certification of whether or not that sewer lateral meets some current standard. A case history was given from City of Alameda California. This was used to present an example of how this would work for the City of Salem and it was shown how it could be used in refinement of replacement responsibility alternatives for the City of Salem. Alameda is a smaller community than Salem, but their whole purpose of instituting the program was because of high I/I. Statistics show that 90 percent of the sewer laterals fail certification tests and are replaced in a home sales approach. There are three responsibility alternatives which have been discussed previously: Alternative 2 (Full Private Responsibility), Alternative 3 (Joint Responsibility), and Alternative 5 (Enhanced Existing Responsibility). These were modified to include the responsibility for an Inspection/Certification program. There was a discussion that there is the potential to reduce infiltration and Inflow (I&I) with an aggressive sewer lateral replacement program and extraneous water removal program but there is currently not enough data available to give an accurate estimate of affect on the peak flow that must be conveyed to the treatment plant. There was detailed discussion of this information. A discussion on the relative construction cost to meet the replacement needs for the various approaches was presented. Policy items discussed at length: 1) Where should the transition for sewer lateral replacement responsibility be? Should the property owner be responsible to the sewer main (owner)? Should the property owner be responsible to the property line and City in ROW (joint)? Should the City be responsible to the sewer main (City)? These minutes are transcribed from notes and the tape recording of the Task Force meeting on August 12, 1999, as an overview of the meeting. They are not verbatim. The tape recorded meeting is available for review in the Office of the Public Works Director. The attachments are to the file copy only. Copies of the attachments were distributed at the meeting and by mail to those unable to attend the meeting. These minutes were approved as written at the Task Force meeting on September 23, 1999.
