I have had water features for 18 years now,started off small with my first one,we moved house and inherited a big back garden,so of course I had to have a pond to match. Took me nearly six months to complete back in 2007,16ft round pond,cascading stream with 5 drops. Built myself another water feature last year consisting of a cascade running out of an 'old ruin' ,this is directly outside on the patio. Anyway,enough chat and here are a couple of photos of my handy work, designed and constructed by myself,no machinery.
