28 Greenfield s Voluntary Approach to PP I/I Reduction Greener Greenfield Program Presenter: Jeff Tamblyn Environmental Engineering / GIS Technician

29 Overview / Guidelines / Goals A voluntary program designed and administered by the City to reduce private property I/I through: Foundation drain disconnection capping palmer valve / sump pump installation / downspout disconnection Sanitary lateral rehabilitation Grading, drainage or piping improvements if they directly reduce I/I Work Plan and Funding Agreement established with MMSD $1.3 million was available to the City through MMSD Initial Work Plan with the MMSD allocated $635K A supplemental Work Plan was recently approved by MMSD to allocate the remaining $688K Design/Investigation/Planning efforts capped at 20% of total allocation Program targets properties built before 1954, assumed to have foundation drain connections and aging clay laterals Program should help to educate residents about I/I issues even if they do not follow the program through to rehabilitation Property data collected as part of program inspections will be provided to MMSD regardless of rehabilitation outcome Program is not intended to be an emergency plumbing repair program. To be eligible for sanitary lateral rehabilitation, foundation drain disconnection must be completed prior to, or in conjunction with lateral rehabilitation work

30 Overview / Goals / Guidelines Residents are not required to correct illegal plumbing/building configurations found during City inspections unless they plan to seek reimbursement from the program. Repairs to fix illegal plumbing/building configurations are not typically covered repairs under the program. City crews will point these out to residents during the inspection Residents contract directly with contractors to complete rehabilitation work. Residents should not incur costs or be obligated until they sign a contract for construction. ** Lateral cleaning costs may apply during investigative phase For foundation drain, sump pump and lateral rehabilitation work, the program reimburses residents up to 100% for the first $6,000 and thereafter at a rate of 75% up to a total of $12,000 per property. $8,000 job = $7,500 program cost + $500 resident cost For grading improvements or modifying existing sump discharges the reimbursement is at a rate of 50% up to a total of $6,000 Program reimbursement is based on the low contract bid. City requires a minimum of three (3) comparable bids before we will grant approval for rehabilitation work to begin Residents are to be reimbursed from the City within a 90 day reimbursement window following construction City should invoice MMSD quarterly for reimbursement related to its administrative efforts

31 5-year Program Target Areas 2400 properties identified with construction before 1954 Properties constructed before 1915 probably have no drain tile 500 contacts per year estimated to be manageable Density of target properties helped determine program areas Part of Year 1 area was in noncompliant metershed.

32 Process Application Inspection - Investigation Data Analysis - Summary of Repairs Quotation Conditional Approval Construction Reimbursement

33 Information packet is mailed to targeted group Applications returned to Engineering Division and entered into PP I/I database Applicant list provided to DPW to coordinate inspection process Application

34 Inspection - Investigation Inspection takes about 1-2 hours DPW - 2 man crew At most, 5 inspections per day Property exterior Site grades Downspouts Property interior Basement plumbing / clean-out Floor drain / sump pump Foundation wall issues Illegal connections Televise sanitary sewer lateral Digital still photos taken as needed Follow-up inspections by Plumbing Inspector may be needed

35 Data Analysis / Summary of Repairs Engineering staff reviews DPW inspection data Same person does each review NASSCO certified Research property records and permits on file Prepare summary letter to identify scope of work and cost estimates under program Resident is provided with materials and asked to obtain 3 quotations Summary letter List of vetted contractors Checklist Copy of data from DPW inspection

37 Conditional Approval Engineering Division reviews contractor quotes and works with Owner + Contractor to verify any issues with quotations. Engineering Division prepares Conditional Approval letter to verify final scope of work and cost estimates under program based on actual quotations. Once Conditional Approval is granted, reimbursement for any changes must be approved by City prior to work taking place. Multiple contractors can be used. Resident is not obligated to use the low bid contractor. Resident pays out of pocket for extra above low bid amount.

38 Construction Completion of construction is required within 6 months of Conditional Approval Reimbursement Resident is required to provide a written request for reimbursement Construction start and end date Contractor information and final invoicing Permit information Digital copy of any photos or video taken In the case of lateral lining, a post-lining video is required City uploads data to MMSD via web interface and makes formal reimbursement request MMSD approves and provides payment to City. City sends owner reimbursement check Reimbursement process typically takes days

41 DPW Inspection Can t properly access basement due to clutter Stuck floor drain, clean-out and vent stack covers Unusual plumbing configurations DPW crews are not plumbing inspectors Laterals not cleaned prior to inspection Damage to lateral push camera Residents say they have lateral cleaned and when DPW re-televised, its clear it has not been properly cleaned People do not always make the best choices Challenges

42 Challenges Engineering Review Summary report Permits and hard copy records at City Hall are not always helpful Questions come up when reviewing DPW inspection data that requires follow-up visit now, or later? What do we do if televising data is incomplete? If our summary is not specific about an item, contractors will take advantage and try to add work Quotation Contractors are busy and don t want to spend a lot of time quoting, especially if they are not getting work as a result --- incomplete quotes There are a limited number of lining contractors in our area Contractor change of scope once work has started more thorough review of quotes Program is based on low bid so we need to make sure that quotes are comparable Quotation phase is typically the lengthiest portion of the project Residents Residents do not always tell the entire story up front Many inquires are made to the program as a result of plumbing emergencies Down payment / final payment concerns before signing contract Residents do not follow through investigations sit idle People changing their minds along the way Reimbursement Data upload process to MMSD for reimbursement is time consuming larger sewer videos do not upload City is not provided with everything it needs from the residents up front Contractors do not always pull permits delays reimbursement requests Dealing with people who are waiting for their reimbursement

50 Choosing PPI/I Project Locations Areas of high sewer flow and/or repeated basement back-ups. Foundation drain disconnection is main focus. Accommodation of sump pump discharges is a major consideration.

51 Past PPI/I Projects First project included lateral lining and sump pump installation. Achieved over 85% peak flow reduction; cost over $10,000/property. 2 projects for sump pump installation with connection to storm following street reconstruction. Cost about $3,500/property.

52 Sump Pump/Rain Garden Project Development Opportunity to implement a green solution for the sump pump discharge. Grant funds available for projects that provide water quality benefit to Lake Michigan through Fund for Lake Michigan. Provides sanitary flow reduction and storm water retention.

53 Sump Pump/Rain Garden Project Funding Sump pump installations funded by MMSD PPI/I funds. Rain gardens funded by grant from Fund For Lake Michigan. MMSD funded workshops and rain garden planting labor.

54 Sump Pump/Rain Garden Project Location Selection In addition to criteria for previous PPI/I projects (high sewer flow & foundation drain disconnect) rain gardens were targeted for areas with: No storm sewer available to connect sump pump discharge. Yards large enough to accommodate rain gardens.

55 Letters sent to 128 properties: 50 responded having interest in work 30 volunteered for install after 1 st site visits 20 were constructed

66 Village of West Milwaukee - PPII MMSD Identified WM6002 and WM6011 as areas that exceeded the Peak Wet Weather Flow Performance Standards Village Performed LSSES that included: Sanitary Sewer MH Inspections Smoke Testing of the Sanitary Sewer Ongoing Sanitary Sewer Flow Monitoring CCTV Inspection of Sanitary Sewers Public Rehabilitation performed, but Sewersheds still exceeded peak flow standard Private Property Issues Suspected Village Selected Dye Testing Investigation

67 Dye Water Flooding Overview

68 Dye Water Flooding Overview Traditional practice that has proven to be an effective method for a variety of purposes In this practice, dye flooding is performed in conjunction with CCTV to confirm potential I/I sources that were identified as part of other investigation methods Dye water flooding aids in verifying both the presence and quantification of specific defects during an evaluation

69 Example: Clay Riser Lateral Leaking Standard CCTV Dye Flood CCTV

70 Village of West Milwaukee - PPII Dye testing of the sanitary sewers provides a roadmap to where leaks are present in your system It is important to note that these leaks are predominantly from unintended crossconnections between the storm and sanitary sewers within the right-of-way

71 Village of West Milwaukee - PPII The majority of the Village properties have foundation drains Dye water noted is separate It creates a targeted approach to reducing private property I/I Important for budgeting May be more sustainable way to continue private property I/I removal work Adding lateral televising during dye testing aids in determining the type of rehabilitation needed Identify location of defects along lateral Reveal challenges that may direct rehab approach

72 Dye Water Testing Costs Sanitary Sewer Dye Testing has been performed for multiple communities, including: City of Wauwatosa City of New Berlin Village of Brown Deer Village of West Milwaukee Village of Butler Village of Greendale City of Brookfield (lateral injection specific dye testing) Over time, the cost of dye testing has become a value-added option to standard CCTV, as local contractors are becoming more efficient at completing these projects Costs vary based on total quantity and size of storm sewer or ditches. Budgetary numbers are as follows: $2.50 to $3.50 per lineal foot of sanitary sewer televised $1.00 to $1.25 is typical cost for standard CCTV of sewer Lateral televised for an additional $325 to $400 per lateral during dye testing process On-site inspection and reporting costs not included in above, but typically correlate directly with the total length of sanitary sewer televised
