This document provides information about Walgett Shire Council's water and sewer asset management project from 2006-2007. It summarizes the process of mapping existing water and sewer pipe networks, collecting asset data, engaging consultants to assess assets, importing asset data and valuations into a software system, designing a defect reporting system, and providing staff training to improve asset management practices. The goal was to meet legislative requirements, improve maintenance records, risk management, and strategic capital planning for water and sewer infrastructure assets.

Raw and Filtered water pipes
• Little written record
of some existing pipe
work
• Majority of historical
data was kept in the
memory of Council
foreman
• Ageing work force
and the importance of
capturing the historical
data before staff
retired

Data Collection
Consulting staff regarding the construction of
the new works looking for data that is incorrect
Site inspections by experienced staff for
missing data eg; pump details ensuring the data
collected is comparable i.e.; metric
Choosing the best resource, proving the
accuracy of the data, adding the missing data
Identifying Existing Assets -
TAMS data bases, GIS, Historical data
Staff knowledge base

Ensure the MapInfo table coincides with Conquest
asset attributes by manipulating the data through access
Importing the Asset into Conquest
Convert the MapInfo table to excel spreadsheet
and down loading into access
