Abstract
Over the past several years, IWK had begun the basic development of GIS taking on a 2-tier approach. The
1st tier was to link all asset location and pertinent information on the assets on a base map. On a more
detailed 2nd tier level GIS, a number of large catchments have information on sewer network and pipeline
components. The customer premises for these areas have also been identified. Over the last few years,
the sewer network information is being verified and updated. Some of the key objectives of IGIS are to
integrate and standardise GIS based systems and data currently in use, to link asset, customer and
operations information to GIS, to make available GIS based asset information to relevant departments
using a web-based GIS system. The Phase 1A of the IGIS system has gone live in February 2009, and Phase
1B, involving integration with other IWK systems is expected to be completed by June 2009.Future
enhancements anticipated include System to be expanded gradually for Tier 2 GIS (individual properties,
sewer network components), Development data on new assets incorporated and Links for live operational
information.
