Ulwe node sewer network project
Navi mumbai, India
Ulwe, a small township in navi mumbai, India, is being developed by the
city and Industrial Development corporation of maharashtra (cIDco). Ulwe
covers 904 hectares, but the sewerage system was originally designed for 80
percent of water demand, or about 128 million liters per day. revised population
estimates and other factors required the sewer network to be truncated.
Based on an ultimate service population of 214,000, cIDco used SewercAD
to revise the sewer network and create a cost- and energy-efficient design.
The new design reduced the number of sewage pump stations from seven to
two with an average sewage flow of about 40 million liters per day excluding
infiltration. Wet-well sewage pump stations with submersible pumps were
recommended to reduce footprints and construction costs.
City of montreal
gIs water and wastewater networks
The Government of Quebec encouraged municipalities to plan for the
rehabilitation and/or replacement of their water and wastewater pipes. Data
was required in digital format so the city of montreal undertook a $20 million
project to collect, analyze, and integrate data in an oracle Spatial database.
The city digitized more than 12,000 kilometers of pipes, 40,000 valves, and
30,000 fire hydrants in its water and wastewater networks.
The interaction between oracle Spatial and microStation, WaterGemS, and
Bentley map eliminated redundancies and discrepancies among archival paper
plans, and enabled the use of lifecycle analysis software to support decision
making. project Wise enabled the city to extract, modify, and post 3D data in a
secure centralized environment with user-specific workspaces.
