Task
Map and inspect the condition of roughly 70,000 linear feet of small diameter, combined sanitary and storm sewer pipes to assist city officials with the separation of these systems.
PROBLEM
- The city was looking to separate and modernize its combined sanitary and storm sewer system
- The only existing maps of the system were from the early 1900s, and were not up to date or complete
- Many of the pipes were over 100 years old and made of vitrified clay pipe, which is hard to crush but will snap when not properly supported or when placed under extreme pressure from an external source
Solution
- GPRS utilized CCTV camera-equipped, remote-controlled rovers and push-fed scopes to investigate and map the system
- A NASSCO-compliant, WinCan Web report was generated detailing all defects discovered, ranking them by severity and identifying them with photo and video evidence
- It was discovered that one of the vitrified clay pipes in the system had completely collapsed
Benefits
- The detailed, NASSCO-compliant report allowed the city and its engineers to efficiently plan for separating and updating the combined sanitary and storm system
- Defects and other issues like the collapsed pipe could be remediated with minimal excavation, saving taxpayer dollars and minimizing disruptions to surrounding businesses and traffic
