  • A sewer ventilation model applying conservation of momentum

    The work presented herein was completed in an effort to characterize the forces influencing ventilation in gravity sewers and to develop a mathematical model, based on conservation of momentum, capable of accounting for friction at the headspace/pipe interface, drag at the air/water interface, and buoyancy caused by air density differences between a sewer headspace and ambient. Experiments were ...

  • Numerical modelling of air-water flows in sewer drops

    The presence of dissolved oxygen (DO) in water flows is an important factor to ensure the aerobic conditions recognised as beneficial to preventing the occurrence of detrimental effects. The incorporation of DO in wastewater flowing in sewer systems is a process widely investigated in order to quantify the effect of continuous reaeration through the air-liquid interface or air entrained due to ...

  • Making Affordability Fit Your Community - A Holistic Approach for Wet Weather Management Programs

    ABSTRACTThe City of Columbus, Ohio is under two consent orders from the Ohio Environmental Protection Agency (OEPA) related to wet weather issues. One order deals with combined sewer overflows (CSO) while the other addresses sanitary sewer overflows (SSO). The City recognized that these two issues were related and needed to be dealt with in an integrated approach. This decision led to the ...

  • Infrastructure Bypass: Rehabilitating the Nation’s Decaying Sewer Systems

    Billions of dollars in federal aid money has been allocated to rehabilitating our decaying sewer systems, and while these are projects that will be done, there will be associated problems with trying to keep roads and businesses open during this work. Typically, in rehabilitating existing sewer lines, the flow of sewage cannot simply be diverted—it must be “bypassed,” which ...

  • Pumps Redirects Sewer Line Emergency Situation in Albuquerque, New Mexico

    Griffin was called by TLC Plumbing in April while working on a project in Albuquerque, N.M., to look at a site where a 54-in. sewer line had collapsed. The collapse had resulted in a major intersection in Albuquerque to be closed and sewage to overflow. TLC had worked to contain the situation, but in order to make the repairs realized, bypass pumping would be required. The sewer line that had ...

  • Multivariate probability distribution for sewer system vulnerability assessment under data-limited conditions

    The lack of geometrical and hydraulic information about sewer networks often excludes the adoption of in-deep modeling tools to obtain prioritization strategies for funds management. The present paper describes a novel statistical procedure for defining the prioritization scheme for preventive maintenance strategies based on a small sample of failure data collected by the Sewer Office of the ...

  • Pumping Stations - Klargester`s range of package systems are efficient, economical to install and are available on short lead-times to fit in with tight construction schedules

    There are a variety of solutions on the market for properties in the UK that are unable to connect to the main sewer by gravity. However, UK building regulations dictate that pumping stations must be used whenever possible. As a result, pumping stations are the most commonly specified solutions for off-mains developments, ahead of sewage treatment plants, such as the Biodisc, and septic tanks. ...

  • A novel freeze protection strategy for shallow buried sewer pipes: temperature modelling and field investigation

    The burial of sewer and water pipes below the maximum ground frost depth can be very costly and laborious in regions with cold winters. If a freeze protection measure is applied, the utility lines can be installed in a shallower trench to reduce the excavation needs. One freeze protection measure, so called heat tracing, consists of supplying heat along the pipes. In this work, the use of 4th ...

  • Sewer mining to supplement blackwater flow in a commercial high-rise Australia-Sydney case study

    Project Background or Rationale Australia’s warm climate and habitual droughts have resulted in innovative water conservation practices in commercial developments, such as 1 Bligh Street in Sydney. Commissioned in May 2011, the highly acclaimed 29 story office tower overlooking the Sydney Harbor captures nearly 100 percent of its wastewater and reuses it in the building. By recycling ...

  • Site acceptance test 12 inch sewer bypass pumps

    Following a European call for tender during the summertime, we were awarded the contract to supply several sewage and flood control pumps. One of the key requirements was an official SAT (Site Acceptance Test). Recently, we successfully completed the first delivery of 12 inch sewage pumps including piping. This video shows how easy it is to set up the complete installation.  Some of the key ...

  • Analysis of acid transport through multi-phase epoxy mortars for wastewater structures

    The characteristics of acid migration through epoxy mortars were examined. Diffusion coefficients of typical sewer bio-metabolised acids: sulphuric, nitric, citric and oxalic acids were determined by gravimetric sorption method and fitted to the multi-phase Jacob–Jones model. Acid permeation was characterised by hindered pore diffusion with the extent being determined by the polarity of ...

  • Town of Jerusalem, New York case study

    Located on Keuka Lake, in the Finger Lakes region of upstate New York, ageing septic tanks were failing and polluting the lake. The Problem Small properties are located on steep slopes. Gravity sewers were cost-prohibitive, costing twice as much as a pressure sewer system. Lot sizes were too small to install new onsite septic systems. The Solution ...

  • Flood analysis of urban drainage systems: Probabilistic dependence structure of rainfall characteristics and fuzzy model parameters

    Flood analysis of urban drainage systems plays a crucial role for flood risk management in urban areas. Rainfall characteristics, including the dependence between rainfall variables, have a significant influence on flood frequency. This paper considers the use of copulas to represent the probabilistic dependence structure between rainfall depth and duration in the synthetic rainfall generation ...

  • Skimmer with rolling stand helps prevent oily water discharge

    Despite continuous replacement and upgrading of fittings, it is difficult to entirely eliminate hydraulic and lubricating oil coming from machines during normal operations and maintenance activities. This oil ends up in different pits used to collect wastewater throughout the plant. Because of high oil content, city officials would not allow plant wastewater to enter the Longmont sanitary sewer ...
