The Importance of Pumps in a Flood Defence Scheme

The presence of pumps in a flood defence scheme will benefit those involved and the success of the scheme. Many consider flood defences to be impenetrable walls blocking water from entering homes and properties. However, the reality is that few possess permanent flood doors and barriers and even the ones that do, can tell you they are not 100% effective and will always have a point where the water can defeat and overtop them. Fixtures such as these are typically pre-installed in anticipation of future flooding, often at high costs.

Pumps offer an extra line of defence say, if the water became too high and breached a flood door. They can pump water away quickly and to a low level, sometimes as low as 1mm. There are also a range of pumps available on the market, with some being able to pump more than 1000L a minute. Pumps are also available in automatic and manual so, for example, if a person’s basement regularly flooded, they could install an automatic pump which would turn itself on when the water reached a certain level and then turn itself off once it had reduced the water to a particular level. Flooding like this typically occurs via groundwater flooding.

Used in conjunction with temporary barriers, pumps offer an inexpensive and effective line of defence against flood waters. Temporary barriers don’t require prior installation like flood doors, can be deployed in a matter of minutes and are usually significantly cheaper. Freestanding temporary barriers, such as the Water-Gate, will always allow a small amount of water to seep through. This is when a pump is needed, as it can stop any seepage from pooling and be pumped away quickly. A defence scheme like this can be stored away and erected in a matter of minutes when there is a threat of flooding. It is ideal for people who are concerned by the threat of flooding, who want to have defences available if it were ever to happen but don’t want to alter the aesthetics of their property.

For the cost, which can be as little as £60, pumps provide an extra, versatile line of defence which will give any flood defence scheme a way to moving water from a property or area at risk to an area where the water can dissipate or be stored. They also benefit the effectiveness of other defences in place, elevating the overall scheme. From domestic to industrial use, there is a vast range on the market designed for every scenario, meaning there will be one to suit your situation.

LSC1.4S Puddle Pump


Pumps that could stop your living room turning in to a swimming pool

Winter is now here, the nights are colder, the days are darker and the frost is in the air. Whether you live in a new build or an older house water pipes can be at risk of freezing and could split or burst causing flooding in your home.

There are hundreds of pumps available on the market but how do you know which YOU would need?

Well that’s very simple, below is our easy guide to help you in those emergency situations:

Basement Pump:

BPS Automatic Puddle Pump

If you have a cellar, whether it be filled with fine wines, treasured items or just the stuff you never got around to unpacking, you want to protect all your possessions. One of the best ways to help protect your cellar from flood water is with a ‘basement pump’ the clue is in the name.

A basement pump can simply be placed in to the water. Turn on and away you go, it’s that easy! You may prefer to leave a pump there permanently and have an automatic pump which will turn on when water is in the basement. This is a popular passive system. There are many different models with different flow rates, this just means how much and how fast it will pump the water. Depending on the size of the room and the amount of water you can choose smaller or larger pumps. In the BPS range of pumps, there is a huge choice and the flow rates vary between 40l/min up to 220l/min!

Puddle Pump:

If it’s a good old-fashioned frost that freezes and burst your pipes this is not what you want. After you have found the issue and turned off the water you are now left with a huge floody mess.

In this instance you may find a ‘puddle pump’ incredibly useful

A puddle pump is simply placed in the puddle or vast lake of a mess depending on the size of your house. All you do is sit the pump in the water and again turn on. When the water has all gone, turn off and you’re home and dry (after you have dried everything of course).

Submersible Pumps or Puddle Pumps:

Flooded Living RoomIf you live by a river or stream, or are even at risk of surface water or groundwater flooding, we can also recommend pumps to help reduce the impact of this flooding.

For this we suggest using a submersible pump in a sump chamber, or again, a puddle pump. The puddle pump means that no chamber is required. These pumps can be fully submerged in the water. Depending on the actual model of the pump these can pump down to as little as 1mm giving you excellent protection from that indoor swimming pool forming in your Living room. Again, there are different models with faster pumping volumes to get rid of the water quicker.

Cumbria Flood Resilience Showcase – Puddle Pump

At Flood Protection Solutions Ltd we are incredibly proud to have recently supported the Cumbria Flood Resilience Showcase by donating a puddle pump.

Our Director, Simon Crowther, is pictured below with Mary Dhonau OBE, who is spearheading the showcase project. Simon is holding the LSC1.4S Puddle Pump:

Cumbria Flood Resilience Showcase Project

The Cumbria Flood Resilience Showcase Project was launched following Dr Peter Bonfield’s ‘The Property Flood Resilience Action Plan’ report published in September 2016.The project is led by the DEFRA Property Flood Resilience Roundtable. It is a government sponsored group which includes members of the Business Emergency Resilience Group (BERG).

The project has been fronted by leading flood resilience campaigner, Mary Dhonau OBE, alongside Adler & Allan, the Environment Agency and the DEFRA Roundtable. The project is supported by companies who kindly donate their time, expertise, services or products. At Flood Protection Solutions Ltd we donated an LSC1.4S Puddle Pump.

Puddle Pumps

Puddle Pumps are a special type of pump which are ideal for flood resilience. Unlike standard submersible pumps, puddle pumps can pump water down to very low levels. The LSC1.4S which we donated can pump water as low as 1mm! This is ideal in flood defence for reducing any ‘residual risk’. If flood door barriers are installed to a property, it is very likely that some water will still enter through the bricks, mortar, or rise up through the floor. A puddle pump can help keep this water level low and reduce any damage caused.

Conventional submersible pumps are required to be at least partially (usually fully) submerged in water to prevent them from burning out; meaning that without a sump pit they can prove ineffective. Puddle Pumps are an ingenious design which solves this, as it allows them to be used in very shallow water without damage.

Within flood defence we believe too many people have the incorrect pump which will not work as expected in anger. We launched floodandwaterpumps.co.uk to make the best quality water pumps available with expert advice.

The donated puddle pump will be used by Botcherby Community Centre in Carlisle, which has been devastatingly affected by flooding in the past. Flooding is an awful experience and is the biggest threat to the U.K as a result of climate change. We’re incredibly proud to have been able to support this scheme and make a difference to the community.
