So why aren't they more common? Well there are more than you might
expect out there, because many are hidden. But we must go back a
few years to understand the thinking today.
Reeds have played an important part in our evolution, and since
man settled into farming, reeds have fed us, protected us, and kept
us dry and warm. Many wealthy landowners built reed beds throughout
the centuries, and the Victorians were great advocates until the
grand building and chemical revolution got underway. Reed beds were
a prime target for `updating' our ablution facilities, because their
replacements gave rise to greater profit opportunities.
It was to take years for the pendulum to swing the other way and
for people to start looking for cheaper, and dare I say it, more
environmentally-friendly alternatives for water and sewage treatment
especially.
All the while, the UK began to lag behind the rest of the world
who had, in many cases, taken on board the commercial and political
benefits of reed beds.
Today reed beds are used in reasonable numbers, but only as a token,
to polish the final outflow from sewage treatment, with some areas
more committed than others.

Unfortunately we still have those with powerful vested interests
who seek to protect their profits rather then consider alternative
money making possibilities. Their main objection is that reed beds
use too much land and take more time to return clean water, compared
with present de facto standard systems.
This excuse is partially true, but the land usage and process time
issues are spurious because design has leapt forward in leaps and
bounds superceding these arguments.
However, we must not forget the negative influences of politics,
job creation schemes, and tax revenues.
Back garden
Reed bed design has moved on and it is now quite conceivable to
build a grey/waste water treatment system for reuse in the back
garden of an average sized three or four bedroom house. A detached
house with a large garden can now be considered for an integrated
reed bed sewage treatment system, and return water for reuse and
compost for the garden, without smell and risk of infection. Reed
beds are no longer dependant upon large flat areas- they can be
built horizontally or in channels, for example.

So, after all the ballyhoo about whether reed beds work we are
left with a situation where individuals must make up their own minds.
However, you may not have to go it alone. There are some Government
agencies and local authorities who are mindful of water conservation
and possible future problems. They are getting their act together
and actively helping people realize their ambitions.
You do not have to be held to ransom over whether your plot meets
certain criteria, making it viable or not. The bureaucracy of forms
and regulations are the result of many years of monopolies and protectionism.
Now we know a little about the history of reed bed politics in
the UK let's look at the positive side of the argument, and the
ease with which we can incorporate a reed bed into your design.
We all have our own ideas as to why we want a reed bed, and the
most common question is can we have one? In many cases the answer
is yes, but you must ask the right people, for advice.
Cheap alternative
Essentially reed beds are a great alternative when considering
building on virgin ground, very old land with specific historic
features, or brown land. The main advantage is financial, because
it can be as much as 30% cheaper to incorporate a reed system than
a present day underground system. Reed beds also blend in naturally
without disturbing the surroundings.
Animal waste can also be treated very effectively without huge
setup costs, whether the animals are pets or commercial. Reed beds
are also cheap to run and maintain compared with established sewage
systems, and more importantly are under your control

of reed beds belies their effectiveness, and specialist

Much has been written about reed beds by academics around the world
and rather than make things more easily understood they have greatly
confused and complicated issues.
The simplicity of the workings of reed beds often seems to defeat
the brains of the best, because they are looking for more than there
is. The reed bed is a home for colonies of bacteria that breakdown
the nutrients from the inflow, whatever it may be, and leave the
outflow as cleaner water. These bacteria have been on our planet
for millions of years doing their job - we don't need to know all
their secrets, we just need to know how to harness them to work
for us.
In many cases a reed bed, or reeds, can be incorporated into another
more conventional system. I believe that no septic tank or underground
sewage treatment system is complete without a reed bed incorporated
into the landscaping plan.
Accidents
Why? Well basically because accidents happen and overflows occur
and floods change dynamics. It is not always possible to detect
overflow or leachate problems from such systems unless it is constantly
monitored. A reed bed will prevent contaminated water entering a
water course, or worse, souring the land.
Most people with general gardening knowledge, or interest can run
and maintain a reed bed with a little help, and adding bacteria
supplements is totally safe. Sampling is also very easy to do and
again very safe.
The simplicity of reed beds belies their effectiveness, and specialist
contractors are not always required if the design is sound and followed
to the letter. Many problems with reed beds arise from cutting corners
and deviating from the design on the pretext that we have not got
the time now and we will sort it out later. Of course later never
comes.

· DON'T - try to do it
on your own just because it looks simple, get a proper design
for your specific development, there is usually not a one
size fits all solution without compromise.
· DON’T cut corners.
· DON’T allow anyone else to have more knowledge
about your system than you have.
· DON'T be put off by bar room pundits - they usually
don't know what they're talking about.
· DON’T talk down to local authority officers
or planners, educate them onto your side. |
· DO incorporate
the bed into the landscape either as a feature or background.
· DO consult the EA or
their publications.
· DO plan for expansion
· DO be aware of the
terrain around your site.
· DO believe a reed bed
is an affordable solution. |
