HomeMy WebLinkAbout10A - Prior Lake Sanitary Sewer Maintenance Policy MEETING DATE: AGENDA #: PREPARED BY: AGENDA ITEM: DISCUSSION: 4646 Dakota Street S.E. Prior Lake, MN 55372-1714 CITY COUNCIL AGENDA REPORT FEBRUARY 2, 2009 10A CRAIG ELDRED, STREET AND UTILITIES SUPERVISOR CONSIDER APPROVAL OF A RESOLUTION ADOPTING THE CITY OF PRIOR LAKE SANITARY SEWER MAINTENANCE POLICY Introduction The purpose of this agenda item is to consider approval of the City of Prior Lake Sanitary Sewer Maintenance Policy. Historv Currently, the City of Prior Lake maintains 565,435 lineal feet or 107 miles of public mains, 2,809 manholes and 39 lift stations within its sanitary sewer system. Although City staff maintains records on maintenance activities, there is no written policy and procedures that state the practices, frequency, direction or purpose for maintaining one of the City's largest assets. Current Circumstances The League of Minnesota Cities (LMC) is the City's insurer and has recommended that all Cities have an adopted policy and procedures to limit liability and ensure coverage by insurance. The procedures identified in this policy are intended to maintain the City's sanitary sewer system to prevent sewer backups and to extend the service life of the system. While developing this policy, City staff took into consideration public safety, city budget, personnel, environmental concerns, and the cost of implementation versus the benefit to be achieved. As in the past, the City will use its employees, equipment and/or private contactors to provide this service. Attached, you will find a copy of the proposed Sanitary Sewer Maintenance Policy and completed Sanitary Sewer System Assessment utilized to develop the Policy. Conclusion The Council is being asked to approve the Sanitary Sewer Maintenance Policy so that staff can implement and educate the citizens of Prior Lake about the policy through pamphlets, local newspaper and additions to the City's website. Staff intends to continue an annual review of the policy and improvement processes, along with periodic annual updates to ordinances which relate to City water and sanitary sewer systems. R:\Council\2009 Agenda Reports\02 02 09ISaoi~CS&0l00al~00ei>o~~4245 www.cityofpriorlake.com ISSUES: This agenda item allows the City Council, City Staff, and the residents of the city an opportunity to completely understand the responsibilities involved in maintaining the city sanitary sewer system. The LMCIT has recommended the City adopt this policy and follow its procedures to ensure that City's insurance is not voided due to unintended actions thereby exposing the City to additional liability. Of particular concern to City Staff is clarification of the City's involvement in sewage backups in private residences caused by plugged sewer mains. The League has been very clear in directing that if a City has an adopted sewer maintenance policy and follows procedures that the City should only assist with cleanups related to sewer backups. This prohibits the City from participating in restoration of property damaged due to sewer backups. The LMC policy on this type of incident is clear in that restoration is the responsibility of the homeowner and they should carry the required insurance protection. FINANCIAL IMPACT: Although there are no current financial impacts, City staff have previously budgeted $2,000.00 for lift station/jetting notifications as part of the sewer utility enterprise fund, account #49450-203. These funds will be utilized to mail pamphlets informing all residents of the new sanitary sewer maintenance policy. The pamphlets and any additional information will be available on the website in the new area under Public Works that relates to sanitary sewer. ALTERNATIVES: 1. Approve a resolution authorizing the adoption of the City of Prior Lake Sanitary Sewer Maintenance Policy dated February 2, 2009. 2. Table this agenda item for a specific reason. 3. Deny this agenda item for a specific reason and provide staff with direction. RECOMMENDED MOTION: Alternative #1 ReVieW~y: ul ~ ~t\A.

Sanitary Maintenance Policy 2009 B. Routine Maintenance and Inspection Goals Sanitarv Sewer Mains Scope of City's Responsibility - The City will maintain the components of the public sanitary sewer system. This includes sanitary sewer mains, manholes, lift stations, and other components. Private property owners are responsible for the maintenance of sanitary sewer service components from their property up to and including the connection to the public system. Examples of these components are as follows: . The entire service line from the house to the city sanitary main line. . The connection to the city sanitary main. . Clean out access points over areas of 100' of service line. . Venting stack cleared of debris to eliminate bubbling or surging of water from toilet or laboratory fixtures. Schedule - The City's goal is to inspect and maintain the components of its sanitary sewer system according to the attached schedule, Exhibit A. The sanitary sewer mains and facilities identified as Category 1 will receive ordinary routine maintenance as noted on sewer maps. The sanitary sewer mains and facilities identified on the sewer map as Category 2 will receive more frequent maintenance and those identified as Category 3 will receive less frequent maintenance. When a sewer main or facility is identified as anything other than Category 1, the reasons why maintenance is needed on a different schedule will be documented. Sewer mains and facilities will receive maintenance according to the attached schedule, Exhibit A. Equipment - The equipment used to perform maintenance will depend upon the equipment available and its effectiveness as determined by qualified staff. Such equipment may include vactor/jetter, easement cleaning machine and other construction equipment to maintain access and repair of sanitary related structures. Television Inspection - The City's sanitary sewer mains will be inspected by television camera in accordance with the attached schedule, Exhibit B. Any sewer mains located on a street where a street maintenance project is planned will be inspected before and after such a project. Sanitary sewer mains in a new development must be televised before said mains are turned over to the City. Television inspection may also be used to inspect the system where there are possible problems. In addition, the City may require any main near a construction site to be televised before and after the construction (Le., near blasting, digging, other activities that might disrupt the main, etc.) Visual recordings of sewer main televising will be required of any vendor performing this service for the City. A written report summarizing and interpreting the findings of the televising will also be required. All visual and written reports must include pipe segmenting. Prior contact with the City Engineering/Public Works Departments must be completed for coordination of pipe numbering segments. Contact Information (952) 447-9830. These records will be kept by the City for a minimum of 12 years. S/Sanitary/Sewer main! Sanitary Maintenance Policy 2009 The Public Works Maintenance Supervisor determine whether a main or facility is Category 1, receiving routine sewer maintenance, Category 2, receiving more frequent maintenance or Category 3, receiving less frequent maintenance. Based on periodic assessment, maintenance will be adjusted and a sewer main may be moved from on category to another. Sanitarv Sewer Lift Stations The City maintains lift stations using specific maintenance that is reasonable and recommended. The number of lift stations, location, date of installation, and capacity of each lift station is kept on record. Maintenance for each lift station is reflected in Standard Operating Procedures (SOP) and Standard Maintenance Procedures (SMP). Components of SOP and SMP are included in Exhibit C c. Inflow and Infiltration Inflow and infiltration occur when clear water gets into the sanitary sewer system. This may occur through cracks or leaks in the sewer pipes and manholes or through sump pumps incorrectly connected to the sanitary sewer system. Inflow and infiltration can lead to backups, overflows and unnecessary and expensive treatment of clear water. City employees will periodically inspect manholes to identify any that contribute to this problem. Sanitary sewer mains will be maintained and inspected pursuant to the City's Sanitary Sewer Maintenance Policy. D. Personnel Responsibilities and Requirements a) Exercise of Professional Judgment It is expected that City employees, in accordance with their job duties and responsibilities, will exercise their professional judgment in the implementation of this policy. Further, it is expected that in emergency situations City employees will be required to exercise their discretion and weigh political, social, and economic considerations including but not limited to public and employee safety, the potential for damage to private property and the City sanitary sewer system, and environmental concerns. b) Training and Education The City will provide training to employees responsible for maintenance of and emergency response to issues with the sanitary sewer system. Training of employees will include education necessary to earn and maintain appropriate operator certifications. Training will also address standard operating procedures, proper use of equipment, emergency response and other topics required by state and federal regulatory agencies. S/Sanitary/Sewer main! Sanitary Maintenance Policy 2009 c) Work Schedule Full-time City employees in the Street and Utilities department will be expected to work eight-hour shifts. In emergencies, employees may be required to work in excess of eight hours. Budget and safety concerns may limit the length of time an employee is permitted to work. d) Weather Conditions Regular sewer maintenance operations will be conducted only when weather conditions do not endanger the City employees and equipment. Factors that may delay sewer maintenance operations include, but are not limited to: severe cold, severe heat, flooding, rain, snow and other severe weather events. E. Documentation The City will document all of its inspection and maintenance activities and emergency responses for its sanitary sewer system. The City will also document circumstances that limit its ability to comply with this policy. A report should be prepared periodically for the purpose of evaluating maintenance activities and for determining goals for the future. These records will be kept in accordance with the City's records retention schedule. F. Public Education Periodically, the City will inform residents of their responsibilities related to sanitary sewer service from the City of Prior Lake. Examples will include the City website (www.citvoforiorlake.com) , Wavelength, and Prior Lake American. G.

SIGNATURE OF PRINCIPAL EXECUTIVE OFFICER OR AUTHORIZED AGENT I SIGNATURE OF CHIEF OPERATOR PHONE DATE DATE CERTIFICA TION# Page D2 of D2 Maintenance Center 17073 Adelmann Street S.E. Prior Lake, MN 55372 Date, The City of Prior Lake is scheduled to clean sanitary sewer mains in your neighborhood on April II th for a period of up to two weeks. The sanitary sewer lines are cleaned using high performance sewer cleaning equipment. A cleaning nozzle is propelled from one manhole to the next using water under high pressure. The nozzle is then pulled back to the starting manhole. As the nozzle is pulled back, water scours the inside of the sanitary sewer pipe. Any debris in the pipe is pulled back with the water. The debris is removed from the manhole with a vacuum unit. If roots are found, they are cut with a root cutter. This process is repeated on every sewer line cleaned. During cleaning of sanitary sewer lines, air occasionally vents into a home through the sanitary sewer service line and ventilation system. When this happens, water in the toilet bowl can bubble or surge or, in rare instances, splash out of the bowl. The common causes of air venting into homes during sanitary sewer cleaning are: air movement from normal cleaning operations, the use of higher pressure needed when cleaning sanitary sewer lines that have a steep slope, sewer lines running close to the building, a plugged roofvent, and the size and complexity of the home's waster and ventilation system. To minimize water splashing out of your toilet bowl, keep the lid down. If you have any further questions, please contact the Public Works Department at 952- 447-9830. Thank you, CraifrEldred- Craig Eldred Streets & Utilities Supervisor www.citvofnriQrlake.com S'\Sanitary\Jetlina\sanitarv sewer clean out informationarmemO.doc Phone 952.440.9675 / Fax 952.440.9678 ... TO: PRIOR LAKE RESIDENT FROM: PRiOR LAKE PUBLiC WORKS DEPARTMENT RE: SANITARY SEWER CLEANING The City of Prior Lake has scheduled to clean the sanitary sewer mains in your neighborhood on for a period of up to two weeks. The sanitary sewer lines are cleaned using high performance sewer cleaning equipment. A cleaning nozzle is propelled from one manhole to the next using water under high pressure. The nozzle is then pulled back to the starting of the manhole. As the nozzle is pulled back, water scours the inside of the sanitary sewer pipe loosening the material in the pipe. Any debris material in the pipe is pulled back with the water. The debris is then removed from the manhole with the vacuum unit. If roots are found, they are cut with a root cutter which also utilizes water during the root cutting process. These processes are repeated or utilized on every sewer line cleaned. During cleaning of the sanitary sewer lines, air occasionally vents into a home through the sanitary sewer service line and household ventilation system. When this happens, water in the toilet bowl can bubble, surge, or in rare instances, splash out of the bowl. We re- mind you that the water that could come from this type of incident is from the bowl itself. Therefore during the two week period it would be beneficial to make sure to keep the lid of your toilet bowl down to minimize the water splashing for your toilet. The common causes of air venting into homes during sanitary sewer cleaning are: air movement from normal cleaning operations, the use of higher pressure needed when cleaning the sanitary sewer lines that have steep slope, sewer lines running close to the house or building, a plugged roof vent, and the size and complexity of the home's waster and ventilation system. If you have questions or concerns regarding this matter feel free to contact the Public Works Department at 952-447-9830.
