Pondless waterfall set into a planted slope built by Scott Anderson Design on Long Island

All the waterfall. None of the pond.

The sound, the movement and the stone, with no standing water anywhere. The right answer for small yards, young families and anyone who wants the effect without the fish.

How it works

The water is there. You just cannot see it.

A pondless waterfall runs on a hidden reservoir instead of an open pond.

We excavate a basin, line it, and fill it with washed stone. The water lives in the gaps between that stone, under a load-bearing grate, where nothing can fall in. A pump sits in that reservoir and pushes water to the top of the run. It comes back down over the rock and disappears into the gravel at the bottom.

You get the sound of moving water and a stone feature that looks like it was always there. What you do not get is open water, a fish load, or a surface that collects leaves.

It is the feature we recommend most often for front yards, for families with toddlers, and for anyone whose yard is too small to give a pond the room it needs.

Standing water: None, the reservoir sits under stone
Typical run: 6 to 20 ft of stream and falls
Build time: 3 to 7 working days on site
Filtration: Not required, no fish load
Weekly upkeep: Top off for evaporation
Winter: Shut down and drain, or run through
Typical range: $6,000 to $12,000
Best for: Small yards, front yards, young families

How it works

Six parts. One loop. No chemicals.

Water leaves through the skimmer, gets pushed underground to the biological filter, and comes back down the waterfall. It never stops moving. Here is the whole system in cross-section.

Built on Long Island

Pondless waterfalls we have built.

A real one

The Shelton train garden.

A homeowner wanted a working outdoor model railroad and a waterfall that read as the mountain behind it. Grade, scale and sightlines all had to serve the trains, not the water. It is the most specific brief we have been given and it is still one of our favourite builds.

Questions

The things people actually ask.

If yours is not here, call.

(516) 729-5668

Is it safe with small children?

That is the main reason people choose it. There is no open water. The reservoir sits below a load-bearing grate under washed stone, so there is nothing to fall into. You get the sound and the movement without the supervision.

Do I still need a pump running all the time?

No. Most clients run it when they are home and enjoying the yard and shut it off overnight. Because there are no fish, nothing depends on continuous circulation.

How much water does it lose?

Evaporation only, and less than an open pond because far less surface is exposed. Expect to top it off every week or two in summer.

Can I add a pond to it later?

Sometimes. It depends on grade and on how the reservoir was built. Tell us at the design stage if a pond is a maybe and we will build the run so it can be converted.

What does it look like in winter?

Either a dry stone stream bed, which still reads as a landscape feature, or a running waterfall with ice forming on the rock, which some clients prefer. Your call.

How long does it take?

Three to seven working days on site for most residential runs. Longer if we are setting heavy stone or building significant grade.
