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.

Five things to know about confined space rescue

confined space rescue essentials

Confined space rescue

In life, being confined is not the most pleasant of experiences and most people do not plan to find themselves in this situation. When one is confined to a location, city, building or circumstance there tends to be a great degree of frustration. People get agitated and somewhat helpless when they are confined in life. Have you ever found yourself confined, restricted, trapped or helpless in a given situation or circumstance? Hold your answer for a minute as we pose the next question to you. How did you feel when you were free from the restriction or limitation? Where there certain steps that were taken to get you out of that limitation, confinement or circumstance? Keep your thoughts streaming as we jump into the core focus of this piece.

    Meaning of a confined space

A confined space could be viewed as any space of a confined nature where there is a likelihood of death or major bodily injury from hazardous elements or dangerous conditions. The easiest way to identify a confined space is not by going into it but by checking to see if it is a compartment with limited openings. This includes: storage tanks, open-topped chambers, vats, combustion chambers, silos, reaction vessels, sewers, duct-work and a poorly ventilated room.

                                                                               

 Five things to know about confined space rescue

1)Risk assessment: Carrying out a risk assessment is a legal requirement for any confined space rescue mission. In the Management of Health and safety work regulations of 1990, regulation 3, a comprehensive assessment of the risk has to be conducted, with the capturing of possible hazards and identifying the appropriate procedures to adopt. It is not a wise idea to jump into rescuing someone trapped in a confined space, without assessing the risk that abounds and the best approach to be taken.

2)Avoid Entering a confined space: You might be spurred by the moment and somewhat rely on your instincts to make a brave rescue attempt. The wise decision is to avoid entering the confined space and quickly contact a trained confined space rescue team. These trained teams will avoid entering the confined space if it is avoidable as different approaches like remote clearing of silos, remote camera inspection and the modification of the confined space could suffice.

3)Implementation of a safe working system: If entering the confined space is the only option, then there is the need to ensure there is a safe working system established inside the confined space. There is the need to have a functional team led by a supervisor who is responsible in making sure precautionary measures are taken.

4)Communications: An effective communication system is required between the teams outside the confined space and those found inside. This is very important as it could prove vital in a case of an emergency.

5)Provision of breathing equipment: A confined space may frequently experience a lack of oxygen or a polluted space. Having breathing apparatus is not just essential but could be a life saver. It is very important for breathing apparatus or gadgets to be provided as the space may not be conducive for breathing because of gas, vapor or lack of oxygen.  It is not advisable to ease or mitigate the air in a confined space with oxygen as this could lead to a possible fire outbreak or explosion.

 The above list is by no means exhaustive but they provide essential points with regards to confined space rescue operation. At Hydro cleansing, our confined space division have fully trained crew that are passionate about putting a smile on your faces through our professional and safe rescue operations.

The difference between septic tank and cesspit

 

cesspit and septic tank emptying

You may rarely come across the terms: ‘septic’ and ‘cesspit.’ To most, this may be the first time you are stumbling upon these terms, as a possible problem with your septic tank or cesspit may have led you to this page. Don’t worry, you are not alone in attempting to find out the apparent difference that exists between these two close elements. Without further delay, let’s delve into the meaning and then establish the difference that exists therein.

 

Septic Tank: A septic tank is considered to be part of a sewage treatment system and does have an outlet that runs to a soak-away. They are believed to require emptying every 12 months.  We will now look at the cesspit before finding out the difference between these two.

Cesspit: A cesspit which is sometimes referred to as a cesspool could be viewed as a holding tank without an outlet. It is also not considered to be part of a sewage system. It is mainly used for the storage of wastes. In terms of maintenance, cesspits are required to be emptied regularly, approximately 45 days, based on the capacity and degree of use.   A cesspit is therefore believed to be an adhoc or temporary solution for areas that do not have main drainage or have incompatible or inappropriate ground conditions. It is a ready and appropriate solution for holiday homes and campsites.

In most cases, cesspits are fitted with an alarm that signals when it requires emptying. An alarm is believed to be the most desired method of examining the rising level in the cesspit, as taking off the lid can lead to the release of unpleasant and harmful gases, which could likely subdue an individual very quickly.

In the UK there are two types of cesspits, which are the domestic and commercials. The domestic is believed to start at about 18, 000 liters and does cater for approximately two people while the commercial starts at about 2,800 liters and go as far as 79,000 liters.

 

The difference between a Septic tank and a Cesspit

Based on the above, it is quite clear that septic is very different from cesspit. Firstly, septic is part of a sewage treatment why cesspit is a holding tank. In addition to this, septic does have an outlet while cesspit do not have any single outlet. Secondly, emptying septic is less frequent than cesspit- as the former is every 12 months and the later every 45 days.

It is also believed that septic is more common in permanent sites while cesspit is more utilized in holiday homes and campsites. A notable difference as well is that septic tanks are considered as a more preferred option due to their permanent nature whilst cesspits are viewed as temporal and last resort.

After reading the above, we hope you now have a bit of clarity around the subjects of septic and cesspit? It is important to state that cesspits can only be emptied by a licensed disposal carrier like Hydro cleansing. It is considered illegal for a non-license individual or body to carry out this service.
