Time saving based on typical 5 day spend on doing this using traditional methods. This has been reduced to 1 days checking and revising. Uses Ordnance Survey’s MasterMap and wastewater network attributes to automatically create seamless catchments that are line with WaPUG (CIWEM's Urban Drainage Group) guidelines. The tool incorporates the following:Analysis is undertaken to determine all roofs; roads; paths; property boundaries and any other semi and impermeable areas.Catchments are identified based on proximity to a network asset, then tested to ensure connectivity. All unconnected catchments are reassigned to a neighbouring catchment ensuring model compliance. Within the output data key attributes are populated such as impermeable area (ha) and area take off (ATO) codes.Subcatchments and Area Take Off’s are exported ready for review prior to direct import into network modelling software.
Trunk Mains Risk Model for Thames Water.Created with Thames Water and designed to support investment decisions during PR09 but now being taken forward and used in day-to-day business to support operational decisions and schedule workBased on common-framework approach – combines probability of failure and consequence of failure. Assesses a number of different consequences including internal flooding, interruption to supply, low pressure, health and safety.Built using an MS Access database – this is so that it’s easy for others to understand and can be handed over easily (the functions are stored in “Queries” not VBA to keep the database simple for others to understand.This is a re-usable model that allows risk scores to be calculated based on different scenarios. Over 1.5GB of data is processed during every “model-run”.The output is a list of trunk main pipes prioritised by risk of failure. This is now being used to target and schedule work for AMP5.
significant amounts of monitoring data (82 auto-samplers, 98 long term flow monitors and 24 rain gauges, such that a single rainfall event could collect andanalyse up to
Southern Water Private Pump Station Strategic Planning Support – Part of 2016 Private Pump Station adoption initativeTask to: Identify all unadopted pump stations within SW’s operating areaConfirm details of sites (owner, maintainer etc)Survey a selection (50-100) to determine condition relative to SW and Ofwat specificationsReport findings to support SW’s adoption strategyHow this was achieved:Single spatial database storing all pump station locations, survey information, contact informationAccessed by ArcMap (for GIS users) and Infopath forms (whole team)362 contacts at 106 organisations were contacted to ascertain pump station locationsCorrespondents with contacts linked to spatial site object using common reference within single db (very joined up)PS locations also identified through web form, SW data mining and third party datasets such as EA consented dischargesSite locations reviewed to determine suitable ‘survey clusters’ which were then targeted for survey on a single day optimising site timeOn a ‘survey day’ survey side of database ‘checked out’, loaded onto ruggedised, GPS enabled 7” tablet PC and populated using Infopath form on siteOnce back in office data checked back in to central database and reviewed using same Infopath formWeekly reporting of progress through site visit programme, maps and correspondence numbersAutomated reporting using maps to show all sites, new sites, surveyed sites etcQueries to determine number of calls, sites resulting from calls etcAsset ManagementStrategy development
OlympicsAutomated failure-to-pipe matching process. Manual validation of mains repair data to improve it (remove duplicate records and ensure correct spatial matching to pipes). Then this data was used to determine mains with high failure rates around Olympic Venues or on the Olympic Route Network (and Embargo roads). Plans for all locations were drawn up and delivered to capital delivery etc.Picture is an example ofthe type of output given to Capital Delivery and local authorities to drive projects forward. Other picture is the data example. Data created by Black and Veatch was used across the business as the starting point for other Olympic analyses (waste, resilience, modelling).
Southern Waters SEMD Site Security Surveys – To undertake 136 security assessments and make recommendations including the cost of those recommendationsSites plotted in Google Earth to support route planning / provide overview before visitCustomised ArcPAD forms loaded onto GPS enabled PDA along with background data for each site10 different forms used depending on what was captured – forms included drop down lists, auto populating fields and tick boxes where possiblePDA captured location of each borehole survey, fence locations, specific recommendations to 2-5m accuracyPhotos also captured on-board and automatically tagged to surveyData returned from field, checked into central spatial database and immediately available on map and via infopath formSurveyor then used Infopath to review field notes and amended where necessary (e.g. converting short hand to full English, adding photos from other sources and making recommendations)Infopath information viewed by estimators to support cost estimations of work – single source of information and photos really helped cost projectInfopath also used as reporting tool with forms being exported directly into report appendiciesSuccess of integrated approach led to PM of Building condition Survey approaching us – To undertake 130 asset condition surveysVery similar, visit sites, complete, form, review form, make recommendations and cost estimates, report findingsMany of the sites on each survey overlapped so single site list used and data fed into same database
Pressure ProfilingPressure management reduces failure rates and increases asset life and return on investment. By bringing together data sources from across the business (we used height data from waste manhole covers to refine our elevation models) we were able to build profiles for trunk mains in areas where tall buildings and principle mains converged. Top right picture is the convergence of buildings, height, and asset data. Bottom left is the 3D image with the asset profile.
Trunk Mains DatabaseA database that stores condition and performance data of Trunk Mains. (combination of DST & asset register).Helps AM understand where the TM assets are, what condition they’re in, the costs associated with maintaining the assets, and helps schedule future works.Improves AM targeting of poorly performing assets and records the decisions made. An audit history of why a leak is not being repaired is as critical to understand as why a leak is being repaired.An interim solution to WAMI – Prototype. When WAMI was conceived the elements related to tracking of trunk main leaks from detection to repair and storing the results of testing was not designed into WAMI. Other elements such as the holding of vital Chamber and Monitoring locations were also not included in WAMI. The aim of TMD is to be an interim solution setting up and defining the processes and information that needs to be stored so that WAMI can take it over in the future.
