Water Wall Units Explained

Written by Danielle Dickinson

Water walls are almost a must in today’s contemporary style gardens. Oftenrepparttar focal point ofrepparttar 147725 garden, this is due not only to their grandeur but also to their tactility. Modern day urban noise such as traffic can be drowned out by such a feature creating a calming environment favourable to sipping a glass of wine and enjoying relaxed conversation. Necessary to create these impressive walls is a prefabricated unit called a Water Wall Trough or Sheet Descent Unit. These units are specifically designed to produce an even flow of water alongrepparttar 147726 entire length ofrepparttar 147727 unit. There are two main types of Water Wall Troughs. Made from Stainless Steel, Copper or PVC, each type distributes repparttar 147728 water in a different way. Below we explainrepparttar 147729 differences betweenrepparttar 147730 two main types of Water Wall Troughs available.

Sheet Descent Water Wall Unit Water Distribution Effect

Pictured above, this unit distributesrepparttar 147731 water fromrepparttar 147732 trough overrepparttar 147733 spout or lip and downrepparttar 147734 surface ofrepparttar 147735 wall into a catchment reservoir or pond (can also be used as a ‘free-fall’ unit). This unit brings subtle noise and movement intorepparttar 147736 garden. Wonderfully tactile, it invites repparttar 147737 onlooker to touchrepparttar 147738 wall and feelrepparttar 147739 cool water running throughrepparttar 147740 hand. The shimmering effect ofrepparttar 147741 water can be captured at night withrepparttar 147742 inclusion of subtle lighting.


This unit should not be installed any higher than 2.0m above repparttar 147743 surface ofrepparttar 147744 water inrepparttar 147745 catchment reservoir. If used as a ‘free-fall’ unit this height reduces to 0.8m. Flow Requirement This unit requires approximately 4500 litres per hour per metre width. This should produce a film of water approximately 3mm thick. Some adjustment in flow is achievable withrepparttar 147746 use of an inline value. See examples 1 & 2 for further explanation.

Catchment Reservoir

Waterfall catchment troughs are designed to be positioned at repparttar 147747 base of a sheet descent water wall whererepparttar 147748 wall surface is fairly even ie. tiles, render, smooth stone, metal, glass etc. They are large enough to suit most submersible pumps. Where a surface is irregular and likely to cause splash such as with pebbles, rock etc a larger catchment reservoir should be used to stoprepparttar 147749 water from splashing out ofrepparttar 147750 feature. Not only is this a waste of water in times of drought but it is truly amazing how quickly a water feature can empty when splash becomes a problem. Rectangular Statue ponds are recommended in these circumstances.


The pump required is governed byrepparttar 147751 flow requirement and head height (ie.repparttar 147752 height at whichrepparttar 147753 waterfall is installed aboverepparttar 147754 surface ofrepparttar 147755 water inrepparttar 147756 catchment reservoir). Example 1:- Installing a 1.0m Sheet Descent at a head height of 2.0m

This unit has a flow requirement of 4500 litres per hour (4500 (litres) x 1 (metre)) therefore requires a pump that will supply 4500 lph at 2.0m high. Check pump performance charts to find a pump that will supply this flow atrepparttar 147757 required height. In this example a Blagdon Amphibious 8000 will push 4980 lph at 2.0m high and is therefore suitable. Example 2:- Installing a 0.8m Sheet Descent at a head height of 1.5m

This unit has a flow requirement of 3600 litres per hour (4500 (litres) x 0.8 (metres)) therefore requires a pump that will supply 3600 litres at 1.5m high. Check pump performance charts to find a pump that will supply this flow atrepparttar 147758 required height. In this example a Seerose UP90 Fountain Pump will push 3840 lph at 1.5m high and is therefore suitable. Projecting Water Wall Unit Water Distribution Effect

Pond Pumps Vs Pool Pumps

Pond Pumps Vs Pool Pumps

Often people install pool pumps to run their water feature because ofrepparttar initial cost savings of purchasing such a pump. This is ill-advised for a variety of reasons; most importantly,repparttar 147724 use of a pool pump can lead to massive increases in your electricity bill.

Also, many unscrupulous landscapers and some retailers provide quotations that includerepparttar 147725 supply of a pool pump rather than a pond pump in order to reducerepparttar 147726 final cost of repparttar 147727 quotation in an effort to winrepparttar 147728 work. They do not informrepparttar 147729 recipient ofrepparttar 147730 quotation ofrepparttar 147731 running costs of a pool pump.

Simple arithmetic proves thatrepparttar 147732 initial cost savings of purchasing a pool pump to run your water feature can cause a blow out of staggering proportions in your annual budget. This is especially true when keeping fish or plants, which requires that your pump is running 24 hours a day to oxygenaterepparttar 147733 water.

Running Costs

To calculate your operating costs per year multiply watts your pump uses per hour, byrepparttar 147734 number of hours you run it per year (if you run it 24/7 then use 8,760 hours per year), then divide by 1,000 to convert it to kilowatts, then multiply by your cost per kWh (kilowatt-hour) ($0.1447 in QLD – see www.energexinstitute.com).

watts x 8,760 / 1,000 x $kWh = $ operating costs per year

Example 1:

A Blagdon Amphibious P8000 Fountain Pump (169 watt)

169 (watt) x 8760 (hours per year) / 1000 x $0.1447 = $214.22 per year

Example 2:

An Average 1.0 HP Pool Pump (750 watt)

750 (watt) x 8760 (hours per year) / 1000 x $0.1447 = $950.68 per year

Total Cost Savings = $736.46 per year ($184.12 every quarter!)
