European Municipal Water & Sewer Utility Migrates 280 Seats to GstarCAD Professional (Illustrative Scenario)
A major Western European municipal water utility managing 24,000 km of water supply and wastewater pipeline networks migrated 280 engineering and GIS drafting seats to GstarCAD Professional. Achieving flawless geospatial alignment under the EU INSPIRE directive and EPSG:28992 coordinate systems, the utility saved €1.68M while accelerating infrastructure data updates by 35%.
Illustrative scenario. This case study is a composite example built from typical enterprise CAD migration patterns. The organization, the people described and all figures are illustrative and do not describe a specific GstarCAD customer.

Executive Audit Summary
Scale: 280 Floating Network Seats | 5-Year Net TCO Preserved: €1,680,000 Saved over 5 Years (82% TCO Reduction) | Binary DWG Accuracy: 100.00% Zero-Loss | Retraining Downtime: 0 Business Hours
1. Industrial Challenge & Recurring License Rental Bottleneck
Serving over 3.5 million citizens across metropolitan Rotterdam and Antwerp, the public utility manages critical water intake, drinking water purification, sewage networks, and flood mitigation canals. The technical department produces continuous pipeline alignment plans, valve chamber details, cadastral boundary alignments, and emergency repair schematics.
For years, the utility maintained legacy Autodesk AutoCAD and Map 3D licenses. However, escalating subscription costs placed an unjustifiable burden on municipal budgets. Furthermore, Autodesk’s Named User policy restricted field maintenance crews and external excavation contractors who only accessed CAD periodically. Public procurement auditors recommended moving to a reliable, perpetual software solution that integrated cleanly with existing enterprise GIS platforms.
2. 30-Day Technical Verification & Standard Compliance Protocol
The utility’s GIS and CAD engineering team established a rigorous 30-day technical pilot focusing on geospatial precision and database integration:
- EPSG:28992 Coordinate System & Raster Geo-Referencing: Engineers verified that high-resolution aerial orthophotos (ECW and GeoTIFF formats) and Dutch National Grid (Rijksdriehoeksmeting) coordinates aligned with sub-centimeter accuracy in GstarCAD Professional.
- Extended Entity Data (XData) & Object Data Persistence: Pipe diameters, installation dates, material specifications (ductile iron, HDPE, concrete), and inspection history stored in DWG XData and extension dictionaries remained 100% accessible and editable without data loss.
- AutoLISP Network Topology Auditing: The utility’s proprietary AutoLISP pipe connectivity analyzer, which detects unclosed sewer loops and dangling nodes using
ssgetandentget, ran at full speed without modification. - Public Safety & Emergency Plotting: Large-format batch plotting (Publish / Sheet Set) of high-density district valve maps for emergency field teams executed 40% faster than legacy systems.
3. Five-Year Total Cost of Ownership (TCO) Financial Audit
A rigorous five-year financial ledger comparison between Autodesk Named User subscription recurring rental and GstarCAD perpetual floating network licensing reveals massive capital savings:
| Investment Horizon | Autodesk® Subscription Model | GstarCAD® Perpetual Network | Net Capital Preserved |
|---|---|---|---|
| Year 1 (Initial License Purchase & Central Server) | €554,400 (280 Named User Subscriptions) | €210,000 (Perpetual Floating Network Licenses) | €344,400 (62% Savings) |
| Year 2 (Annual Maintenance vs Recurring Rent) | €582,120 (+5% Price Increase) | €31,500 (Optional Maintenance Upgrade) | €550,620 (95% Savings) |
| Year 3–5 Cumulative Operational Run-Rate | €1,923,000 | €94,500 | €1,828,500 |
| 5-Year Total Financial TCO | €3,059,520 | €336,000 | €2,723,520 Total Public Capital Preserved |
4. Production Rollout Blueprint & Long-Term Strategic Value
GstarCAD Professional was deployed across three regional utility centers via silent network installation. Floating network licenses managed by GstarLM allowed on-call emergency technicians to borrow licenses onto ruggedized field laptops when responding to water main bursts outside network coverage.
Drawing modification turnaround times decreased by 35%, while public infrastructure audit compliance achieved a perfect score. The retained €1.68M was directly invested in IoT smart acoustic water leak sensors across the regional pipeline grid.
