Pond Free

1. DETERMINE THE OVERALL SIZE AND LAYOUT OF YOUR FEATURE

2. MEASURE THE LENGTH (L) , WIDTH (W), AND AVERAGE DEPTH (D) IN FEET

3. CALCULATE THE WATER IN TRANSIT (WIT)

L = Total Length of waterfall and streamway combined
W = Average width of the streamway and waterfall
D = Average Depth of the streamway in feet (ex: 3” = 0.25’ deep)
L x W x D= Cubic Feet of Water in Transit (WIT) note: 1 ft cubed of water = 7.48 gallons

(Ex: 5’ Length (1’+ 2’ + 6’’ + 1’ + 6’’ = 5’) x 2’ Width x 0.25' Average Depth = 2.5 ft³ WIT 2.5 ft³ x 7.48 = 18.7 Gallons = round off to 20 gallons)

4. RECOMMENDED BASIN SIZE

We recommend a basin that holds 2.5x the amount of water in transit: 2.5 x 20 = 50 gallons
minimum depth must be as deep as pump vault/housing unit

5. SELECT YOUR POND FREE KIT AND PRODUCTS

We recommend utilizing Pond Free® blocks and a waterfall well to allow for a smaller basin. Each block accounts for 30 gallons and waterfall wells add 20 gallons.

(Example: If 50 gallons are needed for the basin, use one matrix block (30 gallons) and a pump vault of 20 gallons. Resulting in a basin size of 2’ x 2’ x 1.5’) When a basin is filled with rock instead of using Pond Free blocks, the hole size is 5X Larger

(Example: 50 gallons x 5 = 250 gallons. Resulting in a basin size
of 4.5’ x 4.5’ x 1.5’)
