ABSTRACT Adding Social Value and Return on Investment Brabant Water is the second largest drinking water company in the Netherlands with a annual turnover of €220 million. Its distribution area covers the province of Noord Brabant. Drinking water is delivered to 2.4 million people through the 84,500 kilometres of mains. GIS is used by the distribution department to assist in the maintenance of the water network. This maintenance can be either corrective or preventive. Annually €1.5 million is spent on maintenance. Preventing interruptions by just-in-time maintenance may save money. On the other hand too much maintenance will increase costs. GIS is used to assist asset management to make the right decisions between just-in-time maintenance or replacement of mains. Investing in just-in-time maintenance on the right assets will reduce operating costs. Using GIS to register mains, house connections and other features of the network helps to avoid excavation damage. This results in a high service level but also reduces costs. Individuals in the Netherlands cannot choose their drinking water provider. This gives the water companies a steady revenue, which makes it possible to invest in less favourable economic times. GIS is used to assist in selecting the investment projects to keep the network in optimal condition.

ABSTRACT The Digital Water and Wastewater Company The Goverment in Denmark has together with the local authorities launched a strategy for digitization 2011-2015. The aim of the strategy is to create a more efficient public service, where citizens communicate with the local authorities through digital channels. Water and Wastewater Companies are exchanging a lot of data with local authorities, so in order to become more efficient, digitization and standardization of data in Water and Wastewater Companies become more and more important. The Danish Water and Wastewater Companies have always had a unique ability to cooperate within the sector and with its external partners. 90% of Danish Wastewater Companies work with the same ‘DANVA data model’ (DANDAS) comprising all wastewater pipes and lots of components. A parallel to this work is the data model made by and for the Water Companies (DANVAND) which in these years is seeing an increase in use. The use of common data models has shown not to have a sufficient level of standardization to meet the efficiency requirements derived from the Danish Water Sector Reform Act, although it is an excellent foundation to work from, because many data in the sector are structured and understood the same way. DDV, “The Digital Water and Wastewater Company”, was established by DANVA, the Danish Water and Wastewater Association, in 2011 in order to lift the digitization and standardization work within Water and Wastewater Companies in Denmark to the next level, making sure that every move (it-strategies, system integrations, data exchanges, workflows etc.) is in harmony with the common business processes in the Water and Wastewater Companies. The “Digital Water and Wastewater Company” is a cooperation between Water and Wastewater Companies in the Danish Water and Wastewater Association. The work and priorities of this cooperation is based on a common vision, saying: ”In 2015 standardization and digitization have increased focus on customer and efficiency in the water segment through better service in all internal work- and business processes and in co-ordination with the surroundings”. The “Digital Water and Wastewater Company” shall work out guidelines and best practices for increased alignment between business processes and data, where the increased amount of data from GIS systems plays a significant role. HOFOR, Greater Copenhagen Utility, supports this effort and this presentation will include: - Short presentation of DANVA and HOFOR - The Danish data models for comprising Water and Wastewater pipes - From data models to DDV, “The Digital Water and Wastewater Company” - DDV guidelines for IT-architecture within Water and Wastewater Companies - DDV projects and activities - The DDV homepage
ABSTRACT EPCOR Water Distribution and Transmission - Redefining Enterprise-wide GIS Water utilities struggle with integrating mapping systems into every facet of their business. Using its Oracle database platform, EPCOR has integrated and deployed various end-user applications, desktop processing environments and interfaces that are used by more than 250 persons daily. EPCOR is completing its fourth major installation since adopting GIS as a business enabling technology in 1977. This recent migration benefited from the acceptance of a GIS Strategy, which outlined three guiding principles: • GIS will improve user efficiency and/or effectiveness • Accurate information should be available to users when they need it, where they need it, and in a format that meets their needs • The database will remain the core of the system and multiple applications will be enabled to meet the specific business user needs This talk will illustrate how well defined database architecture boosts implementation of solutions in the desktop and field environment. EWSI has cultivated a culture where we automate where possible and configure tools before we customize. For successful implementations we have focused on developing solutions from the end user’s perspective, implementing projects in manageable phases ensuring successful user uptake, guarantees funding for training and documentation while meeting the scope of work for GIS.
ABSTRACT Application of Remote Sensing and Geographical Information Systems in Determining the Groundwater Potential in the Crystalline Basement of Bulawayo Metropolitan, Zimbabwe This study is concerned with the production of a regional structural lineament map of Bulawayo Metropolitan from remotely sensed data and geological inference with a view to identify and delineate groundwater potential zones for development in the area. Attempts have been made to review literatures on groundwater exploitation in the study area and the constraints to effective and sustainable management of underground water in the study area. Remote sensing and Geographical Information Systems (GIS) is useful in recognition and delineation of aquiferous zones for potential groundwater in crystalline basement aquifers. Landsat image, SRTM data, aeromagnetic data and other ancillary data sets have been utilized to extract information on the groundwater storing controlling features of this study area. GIS modelling technique of index overlay method was used to produce groundwater potential map. The result further shows that the lineaments in the study area - correlate with faults, fracture zones, and lithological contrasts along fold belts and in crystalline basement rocks, while the main direction of faulting and jointing is north-north-west to north with several faults oriented, to the north-north-east, parallel - Great Dyke. The results have shown massive spatial variability of ground water potential. The variability closely followed variations in the structures, geology, topography/slope, drainage density and land use/cover in the project area. Consequently, about five groundwater potential zones were demarcated in the study area ranging from very good to poor.
ABSTRACT Geographic Information System (GIS) Analysis of an Aquatic Ecosystem: Limnological Parameters in Shahpura lake, Bhopal, India Shahpura Lake, is situated in one of the posh localities of Bhopal, the capital city of state of Madhya Pradesh, India. It receives domestic raw sewage from surrounding habitation; so also the activities like cattle washing, cloth washing, bathing, religious activities like idol immersion etc paves the way for high concentration of hazardous chemicals in the lake waters. The untreated wastewater contains effluent rich in phosphate, caustic soda and detergent, etc. Organic enrichment of the lake through floral offerings, idol immersion and decomposition of aquatic weeds deteriorate the quality of the lake water. With the objective to study the status of the lake a study was conducted from Nov., 2011 to Oct., 2012. The paper presents a study on the Limnological analysis carried out at Shahpura lake Bhopal, India. Twelve sampling sites were selected for data collection. 20 physico-chemical parameters, 14 sediment parameters, diversity and abundance of phytoplankton, zooplankton & benthos and chlorophyll-a were taken for study. Geographic information system (GIS) is used to represent the spatial distribution of the parameters, catchment area treatment, drainage density, land use classification and raster maps were created. The Carlson trophic state index, Nygaard`s algal index and diversity indices like Shannon index, Simpson's index and Margalef index indicated that most of the sampling locations come under eutrophic category indicating that this water is not suitable for human use. Some sites indicated this lake is highly eutrophic.
ABSTRACT Low Flow Index Map for Norway – Interaction using GIS-Software and Analysis The aim of the project is to calculate input parameters to regressions models to estimate low flow indexes for any ungauged catchment in Norway. First part of the study focused on finding regression equations for homogenous regions in Norway. The regression models require a set of catchment characteristics as input parameters. GIS analyses are defined for all the parameters using national datasets prepared or developed at NVE. The user interacts through a web-application towards a GIS server. This automatically defines the catchment from a point, set by the user in the river network, giving the result from the regression models and the catchment characteristics back to the user.

ABSTRACT Water mapping products derived from WorldView2 satellite imagery Around the world, there is a huge need to map shallow waters for navigational, environmental and resource management. Many shallow water areas have either been previously mapped over 100 years ago or not even mapped at all. Many countries desperately need their shallow waters mapped but do not have the necessary funds to carry out these surveys. Satellite derived water mapping techniques dramatically reduce the costs & risks of surveying coastal waters providing nations and organizations an affordable solution to map and understand this increasingly important zone. Satellite Derived Bathymetry (SDB) and water quality monitoring is not a new concept. Since the first remote sensing satellites have been orbiting the earth various techniques have been applied to try and accurately map sea and lakebeds with little success. In the past few years the consortium of Proteus, EOMAP and DigitalGlobe has worked closely together to create satellite derived water-mapping products that are affordable, fast and accurate. The benefits of remotely sensed seabed maps over traditional methods of LiDAR and MBES are numerous as very large areas of seabed can be surveyed remotely at a fraction of the cost & time without the need of permits or mobilizations for aircraft & boats. Satellite derived mapping products for shallow waters is a carbon neutral process and also reduces the risks associated with survey practices such as personnel health & safety and potential damage to the ecosystem. The presentation will discuss the importance of mapping shallow waters and prove that satellite derived water mapping techniques are viable solutions.

ABSTRACT Flood Water Management and City Surface Modelling Floods caused by excessive rainfall have disastrous effects on many cities around the world. Flooding-induced disasters are becoming increasingly frequent and range from local, water-related inconvenience to flood-induced disruption of society and devastation. Under the HydroCity name knowledge institutes and Dutch private and public organizations in the water and earth-observation sectors joined forces to help cities improve their flood resilience. The HydroCity approach has the objectiive to enable communication between the stake holders on a water problem, with its visualisations, analysis and interactiveness in solution design. The technical approach in HydroCity to monitor a drop of rain (or the flood water), from the surface it first touches into the downstream surface water and further if relevant. So e.g. a drop of rain hits a roof, runs off onto the pavement, on the road and into the sewer. In order to monitor the water, the characteristics of all surfaces in a city have to be described and their hydrological properties assesses. In HydroCity the approach we have developed to identify the surfaces developed is (CityGML-IMGEO-)object based. The HydroCity approach implies that a city has a hydrosurface, that covers 100% of the area. This surface consists of objects such as buildings, roads, other paved areas, urban green, water courses, etc. Information on these objects can be obtained from different sources, such as:- city maps and other topographic information;- urban management information systems for urban green, roads, etc. - satellite imagery, air photos, radar and lidar data, etc. From these data the IMGEO-objects are synthesized. These objects are 3D-objects (CityGML Level of Detail 1 or 2). Hydro-environmental characteristics are derived as 3D-shape, surface roughness and infiltration rate. The products are than used to visualize the effect of rainfall and floods on the surfaces using hydrological modeling tools. Given the object approach a very interactive design and management phase with all stakeholders can be performed efficiently and openly.
