Regular maintenance of underground infrastructure is critical to the safety, functionality, and longevity of a city’s sewer system. Manholes serve as vital access points to these networks, allowing inspection teams to assess the condition of pipelines and related components. In the past, inspecting manholes required physically entering these confined spaces, often exposing workers to ...
There is a fair amount of confusion about what makes a product flushable. Manufacturers market wipes and hygiene products as safe for sewer and septic systems. However, the lack of a clear definition leads to expensive problems at wastewater facilities. ...
The U.S. Environmental Protection Agency Performance Track Program is a prestigious program that recognizes the accomplishments of manufacturing facilities that lead the way for improving their facilities’ environmental performance (i.e. reduce air emissions and consumption of water). Brooklyn Navy Yard Cogeneration Partners L.P. is an elite member of this program. They have been ...
Editor’s Note: This post was originally published in 2015 and has been updated for comprehensiveness. With a fleet of 250 tanker trucks—35 of which are used to haul soybean oil—one U.S.-based trucking company is dedicated to thoroughly cleaning its large fleet following transportation jobs. The oil tankers can each haul approximately 48,000 pounds of oil, so when cleaning ...
This growth leads to an increase of impervious surfaces, which generate greater run-off volumes with deteriorated water quality. The original small urban area has a combined sewer system, but separated foul and stormwater systems are compulsory for the new developments. ...

To investigate the different erosion patterns of sediments in combined and storm sewers, sediments from three separate sewer systems and two combined sewer systems in urban Shanghai were collected for the flushing experiments. ...
Together with significant water savings that onsite greywater reuse (GWR) may provide, it may also affect the performance of urban sewer systems and wastewater treatment plants (WWTPs). In order to examine these effects, an integrated stochastic simulation system for GWR in urban areas was developed. ...
Dropshaft cascades are typical elements of sewer systems in steep urban catchment basins. The design of a dropshaft cascade, which is generally addressed as an optimization problem, also needs to consider the subsequent effects induced on the flow by the different elements of the cascade. ...
Although low impact development (LID) has been commonly applied across the developed countries for mitigating the negative impacts of combined sewer overflows (CSOs) on urban hydrological environment, it has not been widely used in developing countries yet. In this paper, a typical combined sewer system in an ...
The risk of flooding in urban areas could be better approached by complementing conventional sewer systems with sustainable urban drainage systems (SUDS) for storm-water management. This may be the case for developing world cities like Dar es Salaam with incomplete sewer services, as well as ...
Linking urban development and urban drainage models is a more and more popular approach when impacts of pavement of urban areas on sewer system performance are evaluated. ...
Few prior studies have examined the potential health risks from transmission of enteric parasites via aquifers contaminated by wastewater from onsite systems. A cross-sectional study of 600 residents in households served with either onsite wastewater systems and private wells or city sewer/water systems in three different sites in central New Mexico compared serological responses to ...
The objective of this work is to introduce a forecasting method for UV-Vis spectrometry time series that combines principal component analysis (PCA) and discrete Fourier transform (DFT), and to compare the results obtained with those obtained by using DFT. Three time series for three different study sites were used: (i) Salitre wastewater treatment plant (WWTP) in Bogotá; (ii) Gibraltar ...
To assess the performance of urban drainage systems in metropolitan areas in southern China, 12 urban drainage systems, including nine separate sewer systems (SSSs) and three combined sewer systems (CSSs) were monitored from 2008 to 2012 in Shanghai and Hefei. ...
Extreme rainfall hammered Boulder, CO with more than 17 inches of precipitation in just six days earlier this year. Salt Lake City’s snowpack—a critical water source—is showing troubling changes in its melting rates. Costly floods and overflowing storm drains plague South Florida’s coastal cities, such as Pinecrest. And storm surge and flooding from Hurricane Sandy caused ...
Primary Treatment is defined as a wastewater treatment process that takes place in a rectangular or circular tank and allows those substances in wastewater that readily settle or float to be separated from the water being treated. This process achieves solids separation. The solids readily available to settle to achieve sedimentation will do so in a settling tank referred as a clarifier. On the ...
This paper presents the results of a study to investigate the performance of an integrated urban wastewater system (IUWS) consisting of a sewer system, biological wastewater treatment plant and receiving water under future climate change and urbanisation. In particular, the roles of both system operational ...
Solid's SmartScan 50L provides an ultrasonic solution for effective sewer management in various locations. The waste water department of Jerusalem municipality in Israel is responsible for managing the city's complex sewer system. The system incorporates several sewage pools distributed in various locations, some of them in hard to reach locations. The problems The city of Jerusalem, with a ...
Abanaki Corporation has been successfully providing oil skimming technology to wastewater treatment plants in the removal of oil from fracking wastewater. Due to the variety of contaminants found in fracking wastewater, the suitable oil skimmer belt for this particular application is Abanaki's high-temp poly belt. This oil skimmer belt is reinforced to resist stretching, is chemically resistant, ...
Tim Ruch, head mechanic at Viessman Trucking in Mankato, Minn., knew that oily sludge was a problem - specifically, the oily sludge in wastewater from cleaning out the company's tanker trucks. Meeting municipal regulations for wastewater effluent involved numerous chemicals, equipment and labor hours. However, after purchasing a fully automatic oil skimmer from Oil Skimmers Inc. of Cleveland, the ...
