# How much water do I need for a pondless waterfall?

## How much water do I need for a pondless waterfall?

As a general rule of thumb, every inch of spillway needs at least 100 gallons of water per hour in order to achieve a standard waterfall flow. If you want your waterfall to be more splashy, you can use as many as 200 gallons for every inch of waterfall spillway per hour.

### How many Aquablox do I need?

There is no formula. It comes down to how often do you want to add water. The larger the basin, the less time between refilling. You could use a 5 gallon pail as your reservoir or 100 Aquablox.

How do you calculate the basin length of a pondless waterfall?

As a general rule, you will need your basin to hold 2½ times the amount of water in your stream. To find out how much water your basin will need to hold, multiply the gallons of water in your stream by 2.5. In the above example, it would be 93.5 x 2.5 = 233.75 – so your basin would need to hold 233.75 gallons of water.

How many Litres waterfall per hour?

You will need to work out the volume of water needed to create an impressive waterfall. You need about 250-350 litres of water per hour of flow per inch (2.5cm). A waterfall with a wide lip will use more water than one with a narrow overflow edge.

## How do you calculate flow rate on a water feature?

So, to determine what flow rate you need, simply divide the total water capacity of your pond by 60. For example: With a 7000 litre fountain, simply divide 7000 by 60 = 116.6. In this case, you need a pump with a flow rate above 116.6/LPM.

### What size water pump do I need for my waterfall?

Flow Rate: The average amount of water moving over a waterfall is 1,500 GPH for every 1′ of width. Therefore, a waterfall that is 2′ wide would need a 3,000 GPH pump. If you are looking for a heavier flow, calculate your flow using 2,000 GPH per foot.

How big a reservoir do I need for a waterfall?

Start by deciding the size of your waterfall. This will also determine the size of your reservoir and whether you want light (100gph per inch of spillway), average (150 gph), or high water flow (200 gph). Your reservoir should be 2-3 the volume of the total water in the pondless waterfall.

How big of a fountain basin do I need?

1. How big is your fountain? Most fountains need a basin that’s 16-24″ larger than the fountain’s widest measurement.

## How to calculate the size of a waterfall basin?

Well all that rockwork will take up space for water, and so you’ll need to go with a larger vessel. Try this quick equation that will help you determine what size basin you’ll need with boulders: L x W x D x 2.2 = gallons of water the basin will need to hold.

### How much does a pondless water feature cost?

This particular pondless water feature project should cost you a total of \$75 – \$100 depending on what materials you need to purchase. You may have some of these items at home, already! If you decide to go the solar route, this will cost closer to \$200. Head over to this post to help you decide between electric or solar fountain pumps.

How big of a drop do you need for a waterfall?

Not much slope is needed (minimum two inch drop per 10 feet of stream). For faster moving water or taller waterfalls, make the grade steeper, which also adds more sound. Plan your stream size first to determine how much water the lower basin and upper pool must hold when the pump is off.

How big of a hole do you need for a waterfall?

Dig the lower basin for the sump basin and surrounding stone and gravel. Dig a square hole at least two feet wider than the basin diameter and six inches deeper than the height. Pro tip: This hole should be at least a foot wider than the stream.
