pond information

I am a student at Derby university in the UK studying Product Design
Innovation & Marketing, I am in my final year and for one of our final
projects we have to design a 'simple pond' for a large British
company. If it is at all possible i was wondering if anybody was able
to e-mail me any information on the following areas; construction,
suitable materials, relivant designs, different features that could be
included (ie, safety features)things that you consider are most
important for first time buyers of ponds. Any information that is sent
would be greatly appreciated. Thanks for taking time to read this.
