How do you calculate the volume of water in ltrs.
For a three meter round pond with virtical sides (walls) 1.5 meter deep.
And also for a square pond 3 meters by 3 meters by 1.5 meter deep.(also with vertical walls)

Hi Kumunryo,
A while since I've done this so here goes:

Square And Rectangle Ponds
Length x Width x Average Depth (in feet or meters) = Volume of Pond
Example:
9.8’ (3.0m) L x 9.8’ (3.0m) W x 4.9’ (1.5m) D = A pond volume of 571 cubic feet(13.5 cubic meters).
=13,500 litres or 2973.5 imperial gallons

Round Ponds
πr ² x depth (3.142 x Half diameter squared x Depth)
Example:

πr² x depth
3.142 x (1.5m x 1.5m) x 1.5m = 10.6 cubic meters.
10,600 litres or 2334 imperial gallons

I've sanity checked the figures on this.

thanks mate.

No Problem!
Do you have a pond or just in planning stages?

Either way, we'd like to hear more.

i currently have a small koi pond at my parents house(1000gallon). sadly my mother has decided that the pond has to go this year as she wants her garden back.
i've decided to build my dream pond in my new garden. so i've decided to start my planning now so when i move in i can get striaght into action. any advice welcome for designing and building my new pond.

on reading back though my post. i must apologise for being so boring and giving a boring life story.
in short. yes im in the prosess of designing my new pond.

Hi,
You are welcome to come and see my plans for the pond I am building at the moment,see the post on Members ponds and Koi section.

Dave.
