A water feature is not solely a pond, pool or fountain. It can be a rockery with water bubbling peacefully through the stones to create your own stream or a three turn urn with a three foot fountain. Similarly to other features in your garden, you should consider it in context with the rest of the garden, be original, try to avoid a 'water feature in a pot' that can look detached from the other garden elements. There are lots of materials that look great, you could use coloured glass and pebbles. Clever lighting can create bright and bold effects or you may prefer a calming, bubbling from beneath a rock feature.
Water features require electricity.
When fitting any type of electrical device in your gardens, but especially around water, make sure that it is done correctly. We all know that electricity and water can be fatal. Ensure any electrical installation is fitted and tested by a qualified electrician. If you wish to keep fish, especially KOI carp, you will need to discuss this with your contractor, as a very high water quality is needed using filtration unit in addition to good aeration with a pump. We're not talking Michaelangelo's David, but a personal piece, or pieces, one that reflects the atmosphere and style of the garden, but also your own style.
