  • Municipal sewer remote monitoring

    Sewers are critical heavy duty infrastructure components requiring costly maintenance. Many municipalities suffer from ageing pipelines that pose higher chances of failure. Sewer leak or overflow results in high cost as a result of civil reimbursement and due to inflected illness. Moreover Civilian frustration that results form the overflow is often targeted towards the municipality. Overflow can ...

  • Rehabilitation of a Large Semi-Elliptical Sewer

    ABSTRACTThe Sanitation Districts of Los Angeles County (Districts) own, operate, and maintain a wastewater treatment and collection system that includes approximately 1300 miles of sanitary sewers ranging from 6 to 144 inches in diameter. A portion of the Districts’ Joint Outfall “A” Trunk Sewer was constructed of cast-in-place reinforced concrete having a semi-elliptical cross section and ...

  • Courtyard-level sewer data-enhanced two-dimensional hydraulic model for urban flood hazard assessment in Kunming, China

    This paper describes a study of urban flooding in downtown Kunming, China, simulating a major flood event that occurred in July 2008 using an improved two-dimensional (2D) hydraulic model enhanced with courtyard-level sewer data (CLSD). Although municipal authorities are not responsible for ‘private’ courtyard sewers, available records were specifically added to this model, ...

  • Evaluating the role of deterioration models for condition assessment of sewers

    Ensuring reliable structural condition of sewers is an important criterion for sewer rehabilitation decisions. Deterioration models applied to sewer pipes support the rehabilitation planning by means of prioritising pipes according to their current and predicted structural status. There is a benefit in applying such models if sufficient inspection data for calibration, an appropriate ...

  • Vacuum Sewers – Engineered Solution for a Multitude of Problems

    ABSTRACTThe City of Albuquerque is celebrating its 300th anniversary in the 2006. The city itself has been growing at a very rapid rate, expanding the urban boundaries into the rural countryside. This urban expansion has been most apparent in the river valleys of the Rio Grande, where groundwater is shallow and topography is very flat. As the urbanization of the valley areas north and south of ...

  • Sewer Siphon Assessment and Air Jumper Design

    ABSTRACTIn response to customer complaints about sewer odor, Orange County Sanitation District (OCSD), California launched a project to investigate the ventilation requirements of existing sewer siphons, to verify adequacy of existing air jumper operation, and determine the need for new air jumpers or additional air jumper capacity. The challenge was assessing sewer siphon air jumper adequacy ...

  • Time for a re-examination of sewer design flow criteria

    Each year, many miles of new or rehabilitated sewer lines or pumping stations are designed and constructed based on flow criteria that may be unrelated to the desired level of system performance. Because of the need to reduce the risk of sanitary sewer overflows and sewer backups into buildings, it can be beneficial to re-examine the basis of sewer hydraulic design. Traditional approaches such as ...

  • A new vision on the condition of city of Toronto’s sewer networks

  • Urine nitrification and sewer discharge to realize in-sewer denitrification to simplify sewage treatment in Hong Kong

    The chemically enhanced primary treatment works in Hong Kong will be upgraded for biological nitrogen removal. This study proposed a novel approach to waive the upgrading by urine source-separation, onsite nitrification and discharge of nitrified urine into sewers to achieve in-sewer denitrification. Human urine was collected and a lab-scale experiment for full urine nitrification was conducted. ...
