  • Rapid detection of sewer defects and blockages using acoustic-based instrumentation

    Sewer flooding incidents in the UK are being increasingly associated with the presence of blockages. Blockages are difficult to deal with as although there are locations where they are more likely to occur, they do occur intermittently. In order to manage sewer blockage pro-actively sewer managers need to be able to identify the location of blockages promptly. Traditional closed-circuit ...

  • Research of the performance of pulse electrohydrodynamics in blockage removal

    In line with contemporary trends and seeking to develop new methods and technologies, a new, original technology was explored and designed based on a non-conventional process of electrical pulse discharge in a water chamber, referred to as ‘Pulse Electrohydrodynamic Technology’ (PELHYDT). The application of the PELHYDT in sewer blockage removal is presented in this paper. Existing machinery can ...

  • 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 ...

  • Prioritising sewerage maintenance using inferred sewer age: a case study for Edinburgh

    The reported research project focuses on using a database which contains details of customer contacts and CCTV data for a key Scottish catchment to construct a GIS based sewer condition model. Given the nature of the asset registry, a key research challenge was estimating the age of individual lengths of pipe. Within this context, asset age was inferred using the estimated age of surface ...

  • Trouble Shooting for Trenchless Liner Installation During Sewer Line Rehabilitation

    ABSTRACTLining is being used by the utility industry as a cost effective solution to rehabilitate utility lines. Many types of liners, such as, cured-in-place-pipe (CIPP), fold and form PVC, deformed & reformed HDPE, etc., are being used to restore structural integrity of deteriorated pipes and to reduce inflow/infiltration. Most of the lining installation is carried out without any problem, ...

  • Combined Sanitary Sewer Overflows (SSO) - Performance Focus: Fats, Oil and Grease (FOG) Reductio Case Study

    In-PIpe Technology Company, Inc., drastically accelerates the natural degradation of fats, oil and grease (FOG) in the collection system, thereby removing blockages and occlusions from the pipe and significantly reducing the occurrence of FOG-related sewer overflows, as well as the requisite equipment and manpower required for the physical removal of these blockages. Since In-Pipe started ...

  • The efficiency of asset management strategies to reduce urban flood risk

    In this study, three asset management strategies were compared with respect to their efficiency to reduce flood risk. Data from call centres at two municipalities were used to quantify urban flood risks associated with three causes of urban flooding: gully pot blockage, sewer pipe blockage and sewer overloading. The efficiency of three flood reduction strategies was assessed based on their effect ...

  • How Much Could You Save by Avoiding a Consent Decree?

    In 2012, St. Louis, MO (Metropolitan St. Louis Sewer District) set a record for the most expensive sewer consent decree in history at $4.7 BILLION to be spent over the next 23 years. The cause of this consent decree and the cause of most consent decrees are overflow events that allow untreated waste into the nearby lakes, streams, river, or other nature areas. There are typically two types of ...

  • Identifying and Strengthening “Weak Links” in the Fog Management Chain

    ABSTRACTRecently, EPA presented statistics that cited grease accumulation in sewers as the leading cause of sewer blockages resulting in sanitary sewer overflows (SSOs). Such blockages can be attributed to fats, oils, and grease (FOG) discharged from food preparation and manufacturing facilities, concentrated residential areas, and even single family homes. Municipalities and wastewater system ...

  • Case Study - The performance of the grease degrading bioproduct greasolux in the meat manufacturing factory and municipal WWTP

    Problem A municipal waste water treatment plant in one Baltic town continuously had problems with the fat, oil and grease (FOG) accumulation in the sewer lines, lift stations and waste water treatment plant, since the start up of a local meat processing facility. The highly polluted waste water directly impacted the treatment plant in the following ways: Increased grease ...

  • Gully and overland modeling during extreme events

    Consultants JBA have been involved in modeling gully and overland flows during extreme events as part of the Interreg IIIB NWE (North West Europe) ’urban water’ project, which is being undertaken by Renfrewshire Council in Scotland. Research for this project was commissioned following flooding in 1994 and 1999. The project takes a strategic look at urban flood risk management on a large scale, ...

  • Ecofriendly Alternative to Fight Grease Build-ups

    Grease traps or Grease interceptors capture the grease that goes down the kitchen drains. The simple fixture prevents slimy build up inside the drainpipes, which may result in choked drains and backflows. It is essential to cleanout these traps timely before the build up is too high to tackle. Properly maintained grease interceptors allow smooth operation of the drains by keeping the water ...

  • Maintenance for septic tanks

    Septic tanks are widely used for on site sewage treatment for domestic homes which are not connected to the sewer system. Little attention is given to the septic tank until there are problems such as smells or poor drainage or ponding on the surface. A little maintenance of the septic tank can be very helpful in maintaining performance of the septic tank. The outflow from a septic tank percolates ...

  • Pipeline Zooming for a Comprehensive Infrastructure Survey.

    Time, budget and resources often keep a municipality from maintaining comprehensive, up-to-date information on water and sewer pipeline conditions. Without a complete understanding of their infrastructures, municipal supervisors cannot properly prioritize and schedule maintenance activities. As a result, emergencies—backups, collapses, and overflows—happen unexpectedly, and must be dealt with on ...
