Hi not strictly a DIY Q's but thought I would just ask. We are soon to
renovate an old barn tho there's a few things

1) The local planning department is opposing the development on the grounds
that it will cause negative impacts on the surrounding area (At present the
barn is falling down and if nothing is done it will be lost)

2) We have a very large deep pond with no water in cos of its size it has no
obvious inflows and would like to be able to use it as a pond.

3) Were keen environmentalists and as such looking at certain things we can
do to decrease impacts from the development.

As such we are looking at having a reedbed constructed to deal with our
sewage and let the fresh water go into the pond, upon Environment Agency
approval. The reasoning behind the reedbed was:
1) To try to prove to the council that impacts will be minimal.
2) To fill the pond up with freshwater and maintain the water level
3) To avoid paying sewage charges
4) To reduce impact of the property.

What I was after was any experiences of such a system pros/cons etc if it
would be suitable to fill a pond. Any possible problems.
Cheers
Oli
