3D Laser Scanning Projects – Western Lakes Sanitary Sewer District

Western Lakes Sanitary Sewer District
City of Duluth, MN

WLSSD operates a wastewater treatment plant, organic composting site, a hazardous waste collection site and solid waste transfer station in the Lincoln Park neighborhood of Duluth, MN.

WLSSD discovered the radial blades of the sewage concentrator were scraping the concrete floor and causing problems.

JPJ Engineering performed a high accuracy surface scan within a 160 foot diameter in the sewage concentrator.

The purpose of the survey was to look for minor inconsistencies on the surface of the concave floor.

JPJ Engineering used a 3D model and high tech software to conclude the sewage concentrator floor was close to uniform with no abnormalities. Further testing will be conducted to determine the cause of the radial blade scraping.
