Takeda Earthfx developed a 3-dimensional groundwater flow model to analyze the impacts of construction dewatering for the Southeast Collector (SEC) Trunk Sewer on groundwater and stream baseflow. The work was done in support of the Hydrogeological/Geotechnical Southeast Collector Trunk Sewer Environmental Assessment. ...
As the sole pump station in that area, it pumps raw sewage 210 feet (64 m) higher than the sanitary sewer trunk. But, with such high pressure and two large pumps, the pump station required extra protection in the event of either power or pump failures. ...
The presence and fate of hydrogen sulfide in wastewater systems were studied in two stretches of an intercepting sewer system located in a coastal village, in Portugal. A range of hydraulic parameters were obtained and liquid and gas phase measurements were carried out, both continuously and through intensive sampling campaigns. ...
Innovative pipebursting approach successfully upsizes old trunk sewer line to serve a new Southern California subdivision Challenge Burst a 350-foot-long trunk line, replacing 10-inch clay pipe with 14-inch SDR-17 polyethylene pipe. Solution We helped Young Homes close escrow on the 95 homes in its Perris, CA development when the ...
Within the present communication, the inspector's uncertainty is quantified by comparing periodic inspection reports from three trunk sewers of a Portuguese sewer system. The inspections were carried out by the same experienced inspector using the same equipment. ...
These centre on OPP–RTI support for the inhabitants of a lane to plan, implement and finance the “internal components” – sanitary latrines in the houses, underground sewers in the lanes and neighbourhood collector sewers – and support for local governments to finance the larger “external” trunk ...
Founded in 1925, the Western Carolina Regional Sewer Authority (WCRSA) is a special purpose district of South Carolina, located in northwestern South Carolina. ...
The antiepileptic drug carbamazepine is a useful anthropogenic marker in groundwater to detect and quantify sewer exfiltration. In 2003 its application on a city wide scale enabled the identification of a trunk sewer in extremely bad structural status with an exfiltration (of wastewater into groundwater) rate in the adjacent area of around 5% ...
The areas of concern include all components of the wastewater treatment system with a strong emphasis on wet wells, manholes, grit chambers, digesters, aeration basins, junction boxes, trunk lines, pumping stations clarifiers and sewer interceptors. The vast majority of these facilities were built shortly after World War II; therefore they were typically built ...
ABSTRACTFor the Flemish situation, storage sedimentation basins are one of the best 'end-of-pipe' solutions to reduce the impact of combined sewer overflows on the receiving waters. In some cases, when the spilled pollution load is too high, the settling efficiency of the basin has to be improved. ...
