Management of Fats Oil and Grease - FOG
Estimates reveal that FOG reaching the nations drains causes up to 75% of sewer blockages and related floods. The management of this waste stream is being taken increasingly seriously by the authorities, including Environmental Health Officers, The Environment Agency and the Water Companies. Not everyone is aware of their responsibilities with regard to this issue, what should be done about ...

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 ...

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 ...

On the preventive management of sediment-related sewer blockages: a combined maintenance and routing optimization approach
In this work we tackle the problem of planning and scheduling preventive maintenance (PM) of sediment-related sewer blockages in a set of geographically distributed sites that are subject to non-deterministic failures. To solve the problem, we extend a combined maintenance and routing (CMR) optimization approach which is a procedure based on two components: (a) first a maintenance model is ...

The Importance of Proper Grease Trap Disposal
If you own a food-service company, then you are no stranger to the disposal of waste grease. The fats and oils, and grease (FOG) that gather in your grease traps are regulated by most municipalities, as well as the U.S. government. If they are not disposed of correctly, they can cause major blockages in sewer lines, and can pollute local water supplies. For these reasons, it is very important ...
