All users access the single source of linear and point asset data. Bottom: Environment and sustainability stored dis- play and stored display of the clean water network W hen water and wastewater company United Utilities (UU) needed to quickly en- hance its existing linear asset manage- ment (LAM) system, it looked to Indian IT and business solutions company Wipro to create a robust and effective solution. There are 800 people who use and edit information on maps every day in UU and around 1,500 more who need to view information about UU sites, network and land regularly. Historically, this activity was enabled through five different systems. The legacy Water GS system held the UU linear and point-on-linear asset data information of water and wastewater networks, and presented this informa- tion in a geographical format. Many network assets had incom- plete attribute data or missing con- nectivity details. The LAM programme led to significant improvement in data quality via updating these gaps as part of the data conversion process. There were sections of network that were missing from the network due to historical processes. Using data con- solidation and inference techniques, these areas were inferred and mapped using a number of agreed business rules. Sewer mapping This has been particularly useful for ex-Section 24 sewers and has enabled these elements of the network to be Asset management enhancement Data consolidation improves UU's operations inferred and mapped. The S199 Water Industry Act requires UU to capture sewer details whenever they encounter a sewer. Historic approaches to data col- lection and modelling had resulted in separate geographic and modelled sewer lengths that could not be reconciled and dissuaded field staff from reporting additional sewer stock. With new techniques, sewer stock can Project focus ● Asset data strengthened ● Commercial billing efficiency leveraged ● Technology delivered alongside training NataSha wiSemaN EdIToR, WWT ● Regulatory compliance: One of the conditions for a license to operate as a water undertaker is to re- cord the position of assets against a recognised map background. ● Outdated legacy system: UU's legacy water GS lacked the functionality to fulfill key contemporary business requirements. ● Lack of single view: there were multiple linear data and mapping systems in use across UU. this led to multiple ver- sions of the truth and poor data quality, which would have risked providing unreliable information to customers. • Drivers be inferred and mapped based on a number of recognised and agreed busi- ness rules, creating a single definitive ex-Section 24 record. Costs for the inferred option are estimated to be less than £100,000, whereas costs to undertake a property survey were estimated at over £50M. Field updates The new UU GIS has resulted in signifi- cantly improved records for field and construction staff and enabled up-to- date hydraulic models for leakage and sewer flooding. Field users attending a leak, having identified the location and status of the relevant valves, are now able to draw an interruption boundary as a temporary layer in ArcGIS Mobile.
