22 LEVERAGING GIS BEFORE THE FAILURE 22

23 SO, WHAT S THIS ALL ABOUT? 23 The Problem Stream bank erosion causing pipeline failure Sanitary Sewer Overflows (SSOs) PRESENTATION OVERVIEW Co$tly emergency repairs The Solution Proactive Site Identification Site Field Review Prioritization and Recommendations 23

24 THE PROBLEM THE PROBLEM Emergency repair Pipeline exposed following an erosion event 24

25 SEWERS AND STREAMS THE PROBLEM: SEWERS ALONG STREAMS Many sanitary sewers built along streams Facilitates access and elevations for gravity flow Increases susceptibility to stream bank erosion Older pipes are especially at risk 25

26 THE PROBLEM: EROSION & EMERGENCY REPAIRS WHEN IT Gradual erosion worsens Potential exists for major failure of stream banks Emergency repairs are necessary weather can impede access Immediate environmental hazard Emergency repairs can be costly Pictured Stream bank failure necessitates emergency repair 26

27 THE SOLUTION THE SOLUTION Analysis and planning can prevent costly sewer failures 27

28 BEFORE A BECOMES AN THE SOLUTION: OVERVIEW Proactive is better than reactive Identify areas of concern Sites Reviewed GIS Aerial Review Field Inspections Identify highest priority sites Estimate cost of prevention Predict and prevent emergency failures, don t wait until it s too late 28

29 WHERE S THE TROUBLE? THE SOLUTION: SITE IDENTIFICATION Accurate sewer locations maintained in GIS Digitize stream bank where pipes cross or follow Review map to identify potential problem locations Stream bank digitization based on latest highresolution aerial photography from NCTCOG 29

30 THE BASICS OF SITE REVIEW Parameters of concern include: SITE REVIEW: MAJOR PARAMETERS All four are considered when prioritizing sites for preventative measures Parameters are evaluated by combining field inspections and GIS review 30

31 SITE REVIEW: BANK EROSION SEVERITY TAKING IT TO THE BANK Stream bank qualities evaluated in the field Each site given a weighted score based on parameters Sites are ranked to facilitate comparison and overall evaluation Scoring matrix adapted from: Bank Erosion Severity 2C Bank Soil Texture 2 Average Bank Slope 1 Average Bank Height 3 Vegetative Bank Protection 3 Bank Cutting 1 Mass Wasting 1 Bank Soil Texture Johnson, P.A., G.L. Gleason, and R. D. Hey, Rapid Assessment of Channel Stability in Vicinity of Road Crossings, ASCE, Journal of Hydraulic Engineering Vol. 125, No 6. Values 1.2 Average Bank Slope 0.6 Average Bank Height 2.4 Vegetative Bank Protection 2.4 Weighted Values Bank Cutting 0.4 Mass Wasting 0.8 Score 7.8 Bank Erosion Severity Ranked Values 3 31

32 THE RISK OF FAILURE SITE REVIEW: INTERCEPTOR FAILURE RISK Failure risk based primarily on bank height Bank height measured in field Difference in bank height and invert elevation gives overall failure risk Stream Stream Bank Failure Plane Stream Bank Toe Field measurements are updated and adjusted based on available contour data HIGH R I S K LOW 32

33 LEARNING FROM THE PAST Aerial photography past versus current Digitized to determine change due to erosion Can determine sewer distance to bank Years to exposure based on rate of erosion progression SITE REVIEW: GIS AERIAL REVIEW 2000 Stream bed Change / Time = Rate of progression 2007 Stream bed Progression rate estimate assumes constant, gradual erosion 33

34 SITE REVIEW: POTENTIAL FOR LEAKING LEAKING POTENTIAL Sewers and manholes evaluated based on: Exposed interceptor/manhole Material Visible damage/deterioration 2000 Stream bed Encasement, rip rap, and other protection Undermining Odor Visible leakage 2007 Stream bed Each parameter is given a score Scores added together for overall leaking potential Analysis of leaking potential allows for more informed prioritization of sites 34

35 REPORTING FROM THE FIELD SITE REVIEW: FIELD INSPECTIONS Field inspections performed by experienced water resources engineers Provide additional information about sites, including: Actual length of stream bank erosion Informed observation of quality/type of erosion Discussion of geological features (e.g. soil type, gullies) Initial comments and recommendations Can obtain GPS location of bank edges Professional judgment and observation complements calculation, scoring, and ranking of site parameters 35

36 PUTTING ALL THE PIECES TOGETHER All parameters are scored, ranked, weighted and combined to determine an overall priority ranking SITE PRIORITIZATION: PRIORITY RANKING Site Bank Erosion Severity Observed Values Ranked Values (1 to 5) Progression Rate (ft/yr) Avg Vertical Dist between Invert & Stream (ft) Leaking Potential Bank Erosion Severity Rankings allow prioritization of sites for recommendations Progression Rate Interceptor Failure Risk Leaking Potential 8C Bank Erosion Condition Bank Erosion Severity Interceptor Risk Progression Rate Bank Erosion Ranking Sewer Condition Leaking Potential Total Priority Ranking Condition Poor 36

37 SITE CONDITIONS Site conditions determine recommendations Good Monitor after rainfall; periodic full evaluation Fair Monitor after rainfall; periodic full evaluation SITE ANALYSIS: CONDITIONS Poor Consider beginning stream analysis and protective measures design Needs Immediate Attention Monitor after rainfall and evaluate annually Erosion failure may be imminent, consider immediate action to stabilize bank Additional recommendations based on unique site conditions 37

38 WHAT DO YOU RECOMMEND? SITE ANALYSIS: RECOMMENDATIONS Options for preventative measures include: Stream bank restoration Engineered solutions Pipe realignment Recommendations depend on site observations Range of repair for various options Address highest priority sites 38

39 EVERYONE WINS! A WIN WIN SITUATION Cost estimates can be compared and selected In general, preventative measures are more Comprehensive Permanent Environmentally friendly Cost effective than emergency repairs Prevention protects the environment from harmful SSOs Bank erosion prevention is a win win for utilities and the environment 39
