How does a preformed pond with waterfall work?
If you install the pond on a sloped area, the pond will seem to be full of water on one side while slightly empty on the other. Imagine filling a cup of water almost to the top and tilting it one way. The water on one side reaches the cup’s edge, and the water on the other side drop down and away, making that side less full.
How to calculate pond volume for a waterfall?
Calculate pond volume using the following equation: length x width x depth x 7.5 = gallons. Sizing a pump for a waterfall involves determining the width the waterfall is, how high up from the pond surface the waterfall starts, and how many feet of tubing will be between the waterfall and pond pump.
How often should a waterfall be pumped out of a pond?
If the pond will have a single shared pump that will also pump the waterfall and one intends to circulate all the pumped water through the waterfall, then it should circulate at least half the volume of the pond once per hour or at least the entire volume if it’s a koi pond. Pumps will be rated in gallons per hour, abbreviated GPH.
How big of a pump do I need for a waterfall?
This means, for example, that a Pond that holds 500 gallons should be powered at a minimum by a 250-gph Pond Pump. If a Waterfall or pond filter is to be powered with the Pump, then the height and width of the Waterfall and/or the flow rate of the Pond Filter have to be taken into consideration.

How many gallons per hour do you need to build a waterfall?
In simple terms approximately 1,400Ltrs (300 gallons) per hour is required for a 15cm (6″) wide fall. All pumps lose volume (flow) the higher you pump the water, so if using an existing pump check it’s capacity. If planning to purchase a new pump, ensure it is of adequate power for your waterfall.
