Obtaining professional flood risk advice is an important consideration for all developments. The role of an experienced civil engineer in reviewing and advising on flood risk measures is necessary to protect potential occupiers. The Environment Agency is correct to reject the cheap mass / computer generated flood risk reports which are available from many of the major UK engineering consultants.However flood risk is often not the only, or even the most relevant planning consideration. There are many different types of risks and modes of flood...read more
Depending on your location it may not be always possible to avoid flood damage, but it is essential to understand the risk and potentially mitigate. The situation regarding flooding is not as black and white as the Environment Agency often presents it. 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...read more
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...read more
Rainwater has been harvested – or collected, stored and then used when needed for hundreds, if not thousands of years. Rainwater harvesting remains a standard technique in many parts of the world without mains water, or accessible groundwater. Most areas of the UK have mains clean water supplies. Increasing demand is however been put on this limited mains system and there is greater consideration of the value of making developments more sustainable. All mains water is treated to a high drinking water standard, yet the vast majority...read more
This medieval church had problems with water damage and took the correct step in requesting professional civil/drainage advice.
We visited the site and inspected the damage and to understand why the damage was occuring. It was clear in two locations of the higher side the rill discharge points had become obstructed with excessive silts and vegetation. We climbed the tower to consider the potential of failure of water collection and discharge of the main church roofs.
