Don’t Let A Flood Ruin Your Festive Cheer!

Hydro Cleansing Will Support You Through the Flooding Season.

Following Storm Angus, Wales and the South of England are currently being battered by high winds and even higher levels of rain fall, and as your Mother would say; prevention is better than cure! If that doesn’t inspire you to get outside and start checking your culverts and clearing your drains, then take a look at some of our flood work from previous years.

Clearing a Culvert Under the A3 Highway:

Here are some of our engineers clearing a culvert beneath the A3 on behalf of a local council. Our expert engineers were down there, in full confined space PPE to cut through the build up of silt with high pressure jets, and of course Megatron, which was on site to suck the waste away for disposal at an impressive 6000 cubic feet per minute. Megatron’s state of the art liquid ring pump creates a vacuum within the bulk tanker in order to efficiently fill it with waste, and also allows a second bulk to replace it while it disposing of the waste. This meant that the work could be continuous and we didn’t have to deploy extra vehicles which allowed us to get the job done quickly.

Flood Response at a Nursing Home in Bristol:

Saving your granny is all in a days work for our teams, or at least back in June it was. We sent out our specialist engineers in a combination vacuum tanker unit to help out a nursing home near Bristol, where the flood waters were about to reach the property. The power of our tanker meant our team could remove the water from the flooded garden area and front of the property where the flood was disrupting traffic and scaring pensioners. Job done!

A life threatening flash flood was vacuumed up in 3 hours by Megatron, Europe’s largest vacuum tanker and the Hydro Cleansing fleet. They delivered an emergency solution to the flash flood in the underpass beside Wallington Station, where 3 cars were swamped by 2m of water on the 7th of June 2016.

1 month’s rainfall fell in 1 hour in a horrendous storm, the lightening from which started several fires across the South of London.  3 cars were trapped. One stalled, the next became trapped as the waters knocked out the engines. The third inexplicably drove into the flood water on purpose. One man was trapped in his car and had to be rescued by a passer-by breaking his car window with a brick, allowing him to get out and wade clear of the water bound car.7V7A0797

Immediately a bulk tanker was dispatched from Hydro Cleansing’s depot in Beddington Lane, Croydon with a police escort and arrived at the scene within an hour of the storm beginning. The three cars were submerged. The 13,000 litre bulk tanker began pumping out the water. 2 combination vacuum tankers followed to the site to remove more of the oil contaminated water. As those tankers left to tip the waste, Megatron, the largest vacuum tanker in Europe emblazoned with transformers graffiti fan art, arrived to clear the rest of the oily waste and empty the 60m soakaway. The bulk tanker returned to relieve Megatron of the waste. The engineers pushed the ruined cars off the road and finally one of Hydro Cleansing’s road sweepers cleared the oily silt from the road The road could then reopen 3 hours after the incident. The fleet of giant orange tankers fulfilled Megatron’s heroic reputation and also provided a neat and tidy end to this environmental thriller.

This kind of flooding is becoming increasingly prevalent. It would be easy to dismiss this as a one off act of God but Paris remains submerged and the forecasts indicate that storms will continue to become more intense as global temperatures rise. “Warming temperatures can make the air hold more water – and that in turn could mean a greater chance for floods”, says Nigel Arnell at the University of Reading, UK. Russell Grattan, Commercial Director at Hydro Cleansing identified that the soakaway under the underpass did have some foliage blocking the flow of the drainage. This flash flood exposed infrastructure weak spots and highlights the need for thorough flood planning to be in place.

Understanding the causes and impact of flooding

Impact and causes of flood

Flood response

Flooding has always been a source of concern for local authorities and residents alike. It is set to occur after a heavy rainfall and when natural watercourses seem not to have the capacity to carry excess water.  It is also argued that flooding is not always caused by heavy rainfall.  On the other hand, it is believed that the quicker the rainwater gets to a river channel, the higher the possibility of a flood occurrence.

Causes of Flooding

Flooding is caused by an array of factors which could be grouped into these three broad categories: Weather events, poor maintenance and developmental/planning issues.

Weather Events: This is one of the most known causes of flooding. These climatic events come mostly in the form of rainfall, comprising of sustained or extensive rainfall and thunderstorm, over a brief period of time. The other weather related cause of flooding is a heavy flow or high tide mixed with stormy conditions.  Most environmental analysts and enthusiasts are convinced that climate change is also set to increase the risk of flooding in the UK and around the globe.

Poor Maintenance:  Aside rainfall, poor maintenance is also a big cause of flooding. It does comprise of factors like: poor maintenance of watercourses, inadequate drainage networks and broken sewer systems.

Development and Planning Issues:  When appropriate planning and development issues are not taken into consideration, there is a higher risk of flooding. These elements comprise of a poorly designed or flawed flood defence schemes, unsuitable development in flood plains and putting up buildings on land, which hinders rainfall from draining away easily. These building or structures could be in the form of roads and car parks, which are impenetrable to water, hence increasing the danger of flooding from rainwater overflow.

 

Impact of flooding

From late December 2013 to January 2014, the UK experienced one of the wettest periods. There were about 183.8 mm of rain, understood to be about 151% higher than average. The south-east and central southern axis of England, during the months of December 2013 and January 2014, witnessed about a 372.2mm of rain, tagged as the wettest two-month period since 1910.

During this two-month period, it is estimated that about 1135 homes were flooded. This was mitigated or controlled due to the flood protection of about 181, 000 homes. Accountancy firm PWC, believe that the clear-up cost for the above flood incident could go north of a £1bn.  Overall, it is believed that the management of flood risk cost the UK government about £2.2bn annually. It is also important to note that about 5.2m properties in England are at risk of flooding from rivers (or seas) and about 1 million are vulnerable to surface-water flooding.

The efforts to manage and provide quick response during flooding is massive. We understand that our homes are embodiment of rich family memories passed from generations and business premises (or shops) are source of livelihood.

We also understand how emotionally important these homes, business premises and public infrastructures are. That’s why at Hydro cleansing, we charge our flood-response division to provide flood response services like removal/disposal of flood water, 24/7 flood defences and professional flood clean-up. We are available 24/7 and have our team readily available to heed your emergency flood related calls. Please use our emergency number: 0208 689 3339.
