Created a spatial map of inferred pipe assets (private drains and sewers) using Machine Learning to support Severn Trent Water Engineers in planning, maintaining, and repairing leaks and bursts within the Severn Trent Water network.

• Generated one of the UK’s largest inferred sewer asset bases spanning 34,000 kilometers by performing big data analysis on millions of sewer assets using a combination of on-premises task scheduling infrastructure and GIS tools, including QGIS, PySpark, Python GIS libraries, and Postgres database in AWS;
• Utilized regression and classification algorithms such as XGBoost, random forest, and simulations using AWS Sagemaker notebooks to estimate the length, location, shape, and diameter of sewers;
• This saved Severn Trent Water hundreds of resource hours and millions of pounds required for manually surveying unmapped assets.
