Below Ground Water Management Systems is the right answer

Many sewer systems in the UK can no longer cope with the surge of rainfall and flooding events and with many urban areas increasingly used for housing and commercial projects, below ground water management systems that can be built upon meaning there is no loss of land take are becoming more valuable.

SuDS or Sustainable Drainage Systems that take into account water quality, quantity and climate change look to control the flow rate of surface water run-off, the storage and collection and treatment of below ground water systems.

In April this year, a new code for sewers adoption came into effect, which included SuDS assets for the first time, with water companies taking ownership and responsibility for sustainable drainage systems.  Introduced in 2014, as one of the main measures to control and mitigate flooding through the Government’s National Planning Policy Framework (NPPF), SuDS looks at natural waterways to control, manage and store surface water runoff.

SuDs should ease the pressure on the drainage network and attenuation tanks have been included in the new guidance for the first time.  Where land is scarce, stormwater attenuations solutions such as an underground tank system can be installed using a precast concrete flatpack system, box culverts or large diameter pipes. 

Below ground, precast water management systems can be used in unsuitable ground conditions, such as high water tables or areas where the soil can be a hazard.  The weather can also pose a risk as some systems can be subject to floatation, the heavy nature of concrete means it does not float.  Some engineered systems can also be badly affected by bright sunlight and hot weather during installation, whilst this may not happen often in the UK, it is happening more and more due to climate change.

According to an English Housing Survey (2014/5) over 75% of the 23.4 million homes in England are over 40 years old, over 56% are over 55 years old and more than a fifth of occupied houses are over 100 years old.  Precast concrete pipeline systems have a design life of over 100 years so can easy match the service life required by the housing market.

Those winter storms are on the way – are you ready?

As we watched in horror the flooding from Hurricane Irma devastate parts of Florida, after causing more than $10bn (£7.6bn) in damage across the Caribbean, a figure which is still rising, we must look at what we can do to protect our infrastructure, both private and commercial from such horrors.

A 2012 BBC report stated that more than five and a half million properties in England and Wales alone were deemed to be at risk from flooding and that you can make permanent changes to reduce flooding and making these alterations can reduce the time and cost of recovering from flooding but can it look decorative?

Here, at Marshalls CPM we believe it can, as our Redi-Rock™ team has developed a flood wall that is doubled sided, with three aesthetically pleasing finishes, so looks great whichever side of the wall you are on and can be installed where space is scarce.

If you need a wall to look great when the flood water has receded as well as offering protection against flooding, then look no further, as our Redi-Rock™ flood walling is what you need.

So how does it work?

The flood walls are laid on a reinforced concrete strip foundation with starter bars into the hollow core. Wall reinforcement is then fixed as the blocks are laid. Once the wall has been completed, the core is filled with concrete to form the watertight barrier, protecting the surrounding areas from the flood water.

So what next?
