Manhole Inspections


EST has experienced staff who perform physical surveys on sewer manholes to locate and document defects and I/I. EST provides written logs which are furnished for each manhole inspected. Manhole surveys document location, structural defects, I/I sources, size, depth, materials of construction, deposition of solids and other pertinent information. EST uses digital camera equipment during manhole inspections to document defects that may be discovered during these investigations.
