Water features - four different products with one name

What is water feature installation?

"Water feature" covers four broadly different things: a self-contained or pondless fountain where water recirculates from a hidden reservoir, a bubbling boulder or urn, a stream or waterfall running into a basin, and a full pond with open water, plants and often fish. All of them need a pump, a power supply and a level, well-built base. What separates them is what you take on afterwards - a pondless feature asks for occasional topping up and a seasonal clean, and a stocked pond is a living system that needs attention all year.

How water feature installation actually works

1. 1

   Choosing the type honestly, against how much attention you will give it

   Pondless and self-contained features hide the water in a gravel-filled reservoir, so there is no open water to manage and very little to go wrong. Streams and waterfalls add movement and sound with a modest step up in complexity. A pond with plants and fish is an ecosystem: filtration, aeration, water chemistry, algae, predation and seasonal care all become part of owning it.

   Watch forA pond being sold on the basis of the installation photograph. Ask specifically what the weekly and seasonal routine looks like in year three, and whether the installer offers maintenance or expects you to do it.

2. 2

   Siting for sound, sight, sun and leaves

   Moving water is heard as much as seen, so features usually belong near where people sit or near a door or window that is open in summer. Sun exposure drives algae growth in open water, and deciduous trees overhead mean netting in autumn or constant clearing.

   Watch forA pond placed in full sun under a tree - the worst combination, giving maximum algae growth and maximum leaf fall. Also check what happens to surface runoff: a feature sited in a low spot collects lawn treatment and silt every time it rains.

3. 3

   Excavation, liner or basin, and the structure

   A pondless feature is built around a buried reservoir - a basin or a lined gravel-filled void - sized to hold the water that drains back when the pump stops. Ponds are excavated to shelves and depths, lined and edged so the liner is concealed and protected.

   Watch forA reservoir sized to the pump rather than to the volume that will drain back down when the power goes off. Undersized reservoirs overflow every time the feature is switched off, which people then blame on a leak.

4. 4

   Pump, plumbing and power - where the electrical trade comes in

   The pump is sized to the height it has to lift and the flow the feature needs, and the plumbing routed so it can be serviced. The electrical supply is licensed work: outdoor circuits near water have specific protection, burial and rating requirements.

   Watch forAn extension cord run across the lawn as a permanent solution. Water and electricity together is exactly the case that outdoor electrical rules exist for, and this is not the place to improvise.

5. 5

   Filtration, aeration and getting the water to settle

   Open water with fish needs mechanical and biological filtration and usually aeration, and a new pond takes time for its biology to establish. Expect an unattractive period early on while that happens - it is normal rather than a fault.

   Watch forA pond stocked with fish immediately after filling. The filtration biology is not established yet, and that is how a new pond loses its first fish.

6. 6

   Edging, planting and hiding the engineering

   The difference between a convincing water feature and an obvious one is entirely in the edges - liner concealed, stone placed so it looks geological rather than arranged, and planting softening the transition to the rest of the garden.

   Watch forVisible liner at the waterline, and stone laid in an even ring around a pond. Both are the giveaways that a feature was installed rather than designed.

7. 7

   Commissioning, winterising and the handover

   The feature is run, the flow adjusted and the sound tuned - small changes in how water leaves a spillway change the noise considerably. You should leave knowing how to shut it down for winter, whether the pump comes out, and what routine it needs.

   Watch forNo winterising plan in a freezing climate. Pumps, plumbing and some feature materials can be damaged by freezing, and the time to learn the procedure is at handover, not in November.

What does water feature installation cost?

Water feature pricing separates by type more than by size: a self-contained or pondless feature is a comparatively contained job, while a stream, waterfall or stocked pond adds excavation, liner, filtration and a larger pump. The licensed electrical supply is a separate line worth pricing early.
