Surface water lines never receive the attention or concern as foul lines. Generally they are seen as a more simplistic system with fewer problems occurring. However surface water lines are just as much the responsibility of the property owner as foul lines, and while they are less likely to become clogged with FOG and other pollutants the results when they are can often be much more serious.
Understanding surface water lines
Surface water comprises of rain fall on your property. This, just like waste water from toilets and sinks has to be disposed of correctly to prevent flooding and other issues on your property. However whereas foul lines are directed towards treatment works, surface lines lead directly back into local water courses, if pollutants like oil, petrol, or fats enter into these there can be serious environmental effects.
All properties have provision for surface water in the form of gutters and drains however premises with large impermeable areas such as car parks face additional pressures. These areas are reliant on surface water drainage to continue being effective and can seriously impact your business if they become flooded.
Surveys and cleansing
EDS can undertake full scale surveys and cleanses of surface water lines to ensure they are free from debris and blockages and that they can continue to function as intended. Though surface water lines should not become blocked with FOG or sanitary products, a great deal of silt, gravel, fallen leaves, and litter can become trapped in surface lines, causing car parks, paths or even your premises to flood.
Surveying and cleansing surface water lines can deal with most problems that occur and will also reveal if there are any more serious problems preventing them functioning such as pipe collapses or roots ingresses. Finding and fixing these issues early can help to prevent larger problems down the line. Surveys can also help to discover if there are any other problems with how the surface water lines are being used, for example if there is evidence of FOG it might show that staff are not properly disposing of fats and oils.
When repair work is required on surface water lines, EDS can be relied on to find the right solution for the issue.
CIPP – Cure in place pipe lining
Cure in place pipe lining can be used for both surface and foul lines and is the first option in most cases. It uses so called trenchless technology which means that it’s possible to repair a pipe line without having to excavate. It uses a resin covered lining which is then moulded to the inside of the pipe using a jet of hot water which cures it in place. Once this is completed, robotic cutters can be used to reopen junctions or lateral connections.
Though it’s usually a last resort, for some jobs there is no alternative to excavation work. When this occurs it’s more important than ever to use a trusted partner with years of experience.
