Building Attenuation Tanks for the purpose of collecting storm water is a good idea!


With the regular water restrictions, hose-pipe bans it makes sense to look at alternative way to gain a supply of water. Attenuation Tanks have become very popular with commercial outlets and now with people for their residential home.

We decided to look at the different reasons why rainwater harvesting using an Attenuation Tank would be a good idea.

1) Beat the hosepipe bans

Hose pipe bans have become a regular occurrence over the years and although the consumer is told to use less water and not to water their garden by a hose pipe, people are still paying the same amount of water bills.

When hose pipe bans are announced, gardeners worry about their garden and the plants and how they are going to survive without any water, thanks to Attenuation Tanks and the harvesting of rain water, gardeners can still water their garden.

2) Save Money

For people who have a water meter, harvesting rain water can save a great deal of money. Instead of increasing your water bill by using your household water for the garden, you can use the water that you have harvested.

Harvested water can be used for other purposes which includes washing the car or the outside of the house.

 3) Having An Attenuation Tank Can Make It Easier To Sell A House

With more people caring about the environment and looking for ways to reduce their foot print and to reduce what natural resources they use, an Attenuation Tank can put property on a property and make the property easier to sell.

It makes sense to build an Attenuation Tank for your residential property. By harvesting rain water it is allowing people to become more environmentally friendly as well as helping to reduce utility bills.

More new property companies are now installing Attenuation Tanks in their new properties; make new homes even more greener.

The Importance of Sea Defence Systems in the UK

As all citizens of the United Kingdom are well aware, the UK has had an extremely wet and difficult start to 2014.  Due to heavy rains, fierce storms, and tidal surges, the United Kingdom has experienced massive prolonged flooding and are scrambling for a solution.  They are experiencing tidal flooding from sea and tidal rivers, fluvial flooding as rivers overflow, groundwater flooding because of the over-saturated earth, and flash flooding as sewers cannot contain the excessive rainfall.

According to, in England alone, more than 5 million properties, both coastal and mainland, are at risk for flooding.  Also, there is a strong risk for more than 200 homes to be completely destroyed due to coastal erosion and flooding within the next 20 years.  An additional 2,000 homes will become at risk during those 20 years.  Climate projections have indicated that sea levels will continue to rise and rainfall will increase; this two situations will definitely result in more and more flooding as time progresses.

What types of sea defence systems can the United Kingdom employ to protect its structures? There are more primitive defences such as seawalls and concrete inland walls. Some more recent defences include allowing flooding in specific areas as a way to direct the flooding.  This controlled flooding normally directs the water away from homes and land covered with concrete towards farmlands where the exposed earth can absorb the water over time.

Coastal areas can also take part in beach nourishment which is a process of bringing in sand from other sources or transporting original sand that has been eroded back to areas that have suffered from erosion.  Some engineers opt to do nothing and let coastal lands that have low value and a small concentration of inhabitants to continue to flood and erode naturally to avoid having to find other mainland areas to direct the flood waters.

The leaders of coastal town, Medmerry, West Sussex, recently used a combination of these options in a project that was completed in the fall of 2013.  They spent two years and £28 million to create approximately seven kilometre’s of new sea walls that were erected behind older defences that no longer kept the water at bay.  While over 350 properties are now protected by the walls, the 180 hectares of flooded land has created a protected costal habitat for a variety of birds and vegetation and will be open to the public as a visitor’s attraction.

There are a wide variety of options for sea defence systems for the UK.  Each option has its own set of pros and cons that the local government officials and citizens must weigh as they determine what is best for their city.  Regardless of what methods are chosen, it is of utmost importance that the residents of the United Kingdom are able to protect their families and their properties from the guaranteed flooding that will continue to affect the country, whether it is located in coastal areas or mainland.

Importance of Flood Defence Systems

Whether you are a business owner, government official or a homeowner, owning real estate or property located within a flood zone or in a lowland puts your precious assets at risk of damage or destruction from flooding. Scientists believe flood events will only increase with global warming and the concurrent rise in sea levels, even affecting areas that were not prone to flooding in the past. Powerful flood waters plus the dirt, debris and waste they carry can ruin furnishings, office equipment or machinery, sheetrock and drywall, wooden floors and structural supports, and more, fostering the growth of mildew and black mold, which is toxic to humans.

The remediation and repair costs of eradicating water damage can escalate quickly, and insurance policies don’t always cover all of the damages. Bearing these catastrophic losses in mind, consider implementing Flood Defence Systems (FDC) today to protect your assets and prevent future destruction of your valuable property.

Flood Defence Systems are available in multiple different forms for homes, businesses and government buildings, and are far more sophisticated and effective than the leak-prone sandbags of the past. Flood barriers and gates, flood resistant doors, anti-flood air bricks, sumps and pumps and self-closing flood barriers (SCFB) are just a few of the available flood defence options. You can also install flood alarms to provide humans and animals as much advanced warning as possible to evacuate or activate other temporary flood control measures.

A layered approach to Flood Defence Systems is best, as initial flood control measures might fail. For example, if sudden high winds cause flood waters to temporarily rise over existing flood barriers, then business owners and homeowners will need to rely on their sump pumps and water blocking doors instead. Whenever possible, install redundant flood control systems. For example, just as a storm window provides redundant layers of glass for protection and insulation in case one layer of glass fails, you should also consider installing redundant Flood Defence Systems. A municipality in a coastal area could install two permanent flood barriers several yards apart from one another to ensure flood waters are restrained even if the first barrier fails.

The properly trained and certified civil engineers working for FDC manufacturers can help advise municipalities, businesses and homeowners about the different flood control options available to each and which combinations of options are best for each site requiring flood protection. Factors to be considered include temporary versus permanent installation, passive versus active flood defence, price, sturdiness and hardiness levels, mobility, aesthetic appearance (for permanent flood defence mechanisms), ease of installation, lifecycle maintenance costs and more.

Whichever Flood Defence Systems you select to protect your real estate, property and assets from water damage and destruction, begin to implement these solutions today, before the next unexpected weather event or water system malfunction occurs. The key is to be proactive and execute your flood protection plans today, because you never know when the next storm will happen, or the next failure of your local dam, levee or floodgate. Arm yourself with Flood Defence Systems now, and rest assured your precious assets will survive the next flood event.
