WATCH MARKET SURVEY 2 Water Utility Deploys iPad Solution L ike thousands of water utilities across the United States the City of Sebring Florida Utilities Department is tasked with providing a safe and reliable water supply while managing all the dispersed assets of the water distribution and wastewater systems This means regularly locating mapping and inspecting assets to maintain service levels and operations When Sebring evaluated this approach the city received a quote for geographic information system GIS software that was more than 30000 and bids for surveying services that were as high as 300000 which didnt include the mobile tools to collect the data or integration with the existing CAD system We could see the traditional GIS and GPS approach was going to eat us alive cost wise said Mark Kretz Water Plant Operations Sebring Utilities Sebring Utilities then researched mobile products to see if other organizations had field success using iPads and iPhones to do the work Sebring still needed to achieve survey grade accuracy sub meter centimeter level in some cases This is impossible with an iPhone or iPad out of the box which delivers 5 meters at best Some tasks such as mapping an underground valve need sub foot or better accuracy Other tasks such as locating an aboveground valve could This City of Sebring storm drain runs down the center of a street be seen within 3 5 meters so just the iPad would work CAD integration Sebring also needed to be able to utilize computer aided design CAD diagrams on its mobile devices to identify and locate valves and other assets in the field In the past the utility relied on printed CAD drawings a was cumbersome and costly solution Plus with time of the essence when containing a leak workers wanted on demand access on their mobile devices With the multitude of assets from fire hydrants to valves to sewers the data collection and maintenance work varied greatly Sebring needed a way to create custom forms and workflow processes and be able to modify them over time or create new ones when needed In the end the city opted to deploy TerraGo Edge on iPads With TerraGo Edge Sebring was able to integrate with GPS receivers that pair to iPads or iPhones via Bluetooth because the product is fully integrated at the 36 GPS WORLD WWW GPSWORLD COM MARCH 2016 software level with Apple certified GPS receivers This enabled the city to cut costs bring surveys in house and improve response times for repairs TerraGo Edge also delivers custom forms CAD diagrams and surveygrade accuracy On a day to day basis the biggest benefit is that we get the ease of use of an iPad and didnt have to buy and use proprietary GPS handhelds which are more complex and vastly more expensive Kretz said Installation of a storm drain in Sebring EDGE BENEFITS Cost savings of 90 percent over traditional GIS and GPS systems Improved efficiency and response times Streamlined operations and insource surveying Use of iPads and iPhones Real time survey grade accuracy with RTK Customizable smart forms
