Swimming pool backwash discharge

Swimming pool backwash discharge

Practically all modern swimming pools in the UK operate with a system of pumps and filters (sand). With the pool water circulating though the sand, deposits (such as hair, oil or dead skin etc) can build up. The water flows in through the top of the filter housing and makes its way down through the sand bed where the sharp edges of the sand catch the many of the particulates prior to recirculation. Many filters will remove particles as small as 20 to 25 micrometres, reducing the extent of visible suspended solids.   How does pollutant...

Their maps are limited to only some of the flood risks associated with new or existing developments. The flood maps relate to land rather than specific buildings with specific floor heights. For the public, it is not flooding generally which is of concern. Some flooding is both natural and can...

Gatwick Airport Radar Tower avoids Christmas 2013 River Mole Flood

Gatwick Airport Radar Tower avoids Christmas 2013 River Mole Flood

The floods at Gatwick Airport around Christmas 2013 in relation to the River Mole caused considerable disruption when an electrical substation flooded. Such disruption to key infrastructure is completely unnecessary if competent Civil Engineering Consultants are employed to assess sites and produce appropriate flood mitigation solutions. At Wilsham Consulting our Engineers have experience of flood mitigation design for a wide range of clients, from domestic sites to key infrastructure. A good example of this is the NATS Gatwick Airport Radar...

Floodplains and flood defences

Floodplains and flood defences

The concept of maintaining areas and entire ecosystems where water traditionally has flooded is critical, both to protect the natural habit and provide the natural attenuation from rivers to protect people's homes and businesses. It was a well understood concept and for thousands of years, flood plain land has been protected. Many civilisations around the world have evolved around such flooding, with the Nile in Egypt an excellent example. Such flooding was celebrated due to the renewed fertility of the land. During the last 10...
