AECOM completed smoke testing, flow and rainfall monitoring, and developed a hydraulic model to evaluate two options to prevent the SSO events for typical storm events. The two options were to increase the downstream capacity of the sanitary interceptor sewer system which was deemed not cost ...
I/I can increase sanitary sewer overflows, which can impact the environment. I/I can also rob precious wastewater treatment capacity from other needs including desired growth. Traditional methods to investigate and identify I/I include closed circuit television (CCTV) inspection, smoke testing and ...
During the first year of sanitary sewer assessment 1,363 manhole and 301,124 linear feet of sanitary sewer lines were inspected. The manholes were inspected utilizing NASSCO's MACP inspection guidelines while the sewer lines where inspected using a combination of smoke testing, dyed water flooding...
An analysis was conducted on the benefits and cost effectiveness of different inflow/infiltration approaches (slip-lining sewer lines, stormwater manhole inserts, replacing sewer lines, smoke testing, etc.) and cost savings municipalities can expect to receive from each.;Unlike most other studies, ...
Through post-audit flow monitoring and smoke testing, it was shown that many private laterals did not have cleanout caps, which allowed for large amounts of rain to enter the system.Proceedings of the Water Environment Federation
