Since 2010, B&N has worked with the City of Duncanville as part of its Annual Sanitary Sewer Evaluation Survey (SSES) Program. B&N’s field crews have conducted smoke testing on sewer mains, manhole inspections and closed-circuit television (CCTV) inspections. Each year, these inspections aim to identify and address potential sewer system deficiencies, minimize inflow/infiltration (I/I) sources that impact plant operations and surcharge conditions and ensure optimal system performance.
All data was collected electronically using Access Database and ArcGIS. Providing information digitally and in one location minimizes the risk of misinterpretation and makes it easier for the City to visualize and prioritize that data.
These annual inspections minimize the environmental impact to the City’s sewers and provides quality utilities to the community.
