1 GIS at EWS 21 April 2016

2 GIS Systems at ethekwini Water and Sanitation Data Collection for 28 years and still in progress Supports all departments within EWS Maintains all the required feature classes that are required by EWS Water and Sanitation Current system contains around 205 Gigs of information System Design based on the requirements of EWS Must be accessible to all Staff Must be easy for general users to use Must be continuously updated and upgraded Search Tools Developed

3 GIS Base Maps Water Basic Map Sanitation Basic Map Water Technical Map Sanitation Technical Map

4 Planning Needs assessments Infill Projects Proposed Water and Sanitation Design Master Water Plans Master Sanitation Plans Hydraulic models for water and Sanitation Info Water Info Sewer

5 Drawing Office GIS used to create Rural Services Drawings Published as a GIS Feature Class Drawings Plotted using GIS No DXF transfers required Proposed Pipes captured into the GIS No Need to re capture

6 Operations Map Books A3 for: Reticulation Streets ARCGIS Software basic electronic maps Mobile Applications in progress GIS Support GIS Issue Reporting to the GIS Office Returned marked up map books Reported issues Report Forms

7 Call Centre Faultman II Database Streets Database Operations Clip Boards per Operational Area GIS Based Data Streets Coded into Operational Areas Water Streets Coded into System Areas Sanitation Streets Codded into Pollution Zones Streets Codded into Roads work Areas Dispatch of fault repairs is undertaken by Geographical Areas GIS supports advanced (non Standard address quires) Returned information from Job Cards can be analyzed in the GIS

8 Water Supply Zones Location of Valves Location of Pressure Zones Locations of Zone Dividers Location of Bulk Meters Pressure Reduction Projects

9 Asset management Network Assets Water and Sanitation Facility Assets Storage Facilities Water Pump Stations Bridges Tunnels Current Replacement Cost of all Network components Insurance Registers Condition Assessments at Level I & II Life Cycles tracking and recording Remaining useful life Calculations Age Condition

10 Water and Sanitation GIS Support Data Cadastral WaterCad Proposed Parcels Registered Cadastral Hexagons (25m sides) Streets Network Suburbs Feature Classes Address Points Billing Database Linked to Cadastral

11 Survey Office Survey Planning GIS Survey Feature Classes for Trig and TSM s

12 Water Meters Meter Routing Meter Locations Meter Service requests Meter Route Sequencing Meter Applications Meter Life Cycle tracking All Meters are Co-ordinated

13 Billing GIS Interface with the Billing System Property Key Billing extract once a week creating spatial billing Spatial Arrears Spatial Disconnections Spatial Consumption Audit of Serviced Properties

14 GIS Software options ESRI / Other ELA with ESRI System Design, ESRI has a massive support base Development of Standard Operating Processes (SOP s) Standards for data capture Standards for as built information Keeping it all up to date QA / QC

15 GIS Reading ArcUser - free ArcNews - free ArcWatch - free Esri Globe - free Arc Press (Large number of books available contact ESRI South Africa) Wiki.gis.com Gisgeography.com/free-gis-software/ for links for free GIS Software

16 GIS and Survey Staff

17 GIS / GPS Training at EWS One day course is offered to all EWS GIS users (End course test) Three day advanced course will be offered to all EWS GIS users before June 2016 (End Course Test) Training is offered to expand the use of the GIS systems within EWS Expand Data Awareness Direct support / Telephone support is available to all EWS GIS Users from the GIS Office & GIS Trainer

18 Underground Services need to be verified Water and Sanitation infrastructure is largely underground Confirmation of location is required Confirmation of attributes is required (Size and Material) How and who at EWS does this?

19 GPS and Field Equipment Geotagging cameras Garmins or Personal Navigation Devices (PNDs) Trimble Juno s hand held devices Trimble GeoXH hand held devices Cat and Genny Ground Penetrating Radar

20 GPS Units Garmins or Personal Navigation Devices Used by field staff for Navigation around the Unicity. Saves time and resources as it is able to direct crews right to a problem. The main reason we use these units is savings in time and cost to council. Reducing travel time to and from site enables us to do much more in a day.

for attributes Assists with the alignment to GIS with Data Dictionary

21 Data Dictionaries for field capture Simplifies data capture Moves you from the pen and paper to electronic formats Choice list based options for attributes Assists with the alignment to GIS with Data Dictionary development tools GIS Features DD unit Screen DD Development Desktop software

22 GPS Equipment used by EWS (Low Accuracy) Trimble Juno s hand held devices Accuracy 1 to 3 m Built in Camera for Geotagging images Allows the capture of many attributes per feature Device uses Meter Reading Asset management life cycle audits Rural House Numbers Pollution Inspections Recording the installations of Flow Restrictors Plus many more

23 GPS Equipment used by EWS (High Accuracy) Trimble Geo hand held devices Accuracy 0.1 1m Built in Camera for Geotagging images. Has 3G data capability Device uses Infrastructure As Builts for example Pipelines, Valves, PRV s, MH s etc)

24 Location of underground services Cat and Genny Allows you to trace metallic underground services such as steel pipe

25 Location of underground services RD1000 Ground Penetrating Radar Allows us to trace non metallic underground services up to 8 meters deep Tracing teams still have to confirm the type of service Screen view of underground pipe
