2015-12-15 CC Spec Wksp Sewer PPTSewer Lateral Program Workshop December 15th, 2015 Next Steps: Direct Staff to prepare ordinance/code changes to match desired program Language written by staff, engineering, legal, and reviewed For council consideration at a later date Next Steps: A proposed ordinance should... • Re -define ownership boundaries of sewer laterals • Define and establish Point of Sale program • Define and establish Demo/Rebuild/Addition Program • Define and establish Voluntary/Self Reporting Program • Define Clearwater, Inflow • Define Cross connections • Define sump pump discharge connections • Define foundation drain and down spout connections • Define Infiltration • Define broken/leaky pipes • Define the appearance of groundwater flow • Define and establish sewer fees to sewer bills Risk Targeted Inspection Projects: Funding options available to pursue inspection projects • G.O. Funds • Spreads cost over greatest number of taxpayers • Sewer Revenue funds • Mindful of the current rates • We are already spending these dollars in a similar fashion to satisfy MCES Surcharge/required work • Need to make sure we continue to tackle municipal main projects as well • 1/1 sewer fee • Fees could be dedicated to 1/1 work and the balance of the fund could dictate the amount of work to be performed Risk Targeted Inspection Projects: • Update analysis performed in the 2007 1/1 study with up to date data, and include MCES lift stations with new data (the white hole phenomenon in our maps) • This would allow us to focus on high 1/1 areas that we know exist from available data • Laterals would be televised, paid for by the city • Certifies the home free of Inflow sources: • No Cross connections • No Sump Pump connections • No Foundation drains or downspout connections • Damaged or leaking/infiltrating lateral pipe are recorded and will trigger repair at point of sale or at a later date reserved by the city Risk Targeted Inspection Projects: • Discovery of Inflow connections would require repair within a certain time frame • Inflow connections would initiate the sewer fee if not completed within a reasonable amount of time • Damaged or leaking/infiltrating lateral pipe are recorded and will trigger repair at point of sale, or at a later date reserved by the city 33 Risk Targeted Inspection Projects: •�• CITY OF MOUND INFILTRATION & INFLOW STUDY w I � t & 1 RANKING BY IFr ------ ATION � SERVICEAREA _. -- I1ER LFI i FIGURE NO.
