Pond construction

Ron's pond 4. Laying the pipes and bottom drains


A close up of the pipes connected to one of the bottom drains.
The radius bends fitted to the bottom drains are designed to reduce resistance to a minimum.

A damp-proof membrane has also been laid across the excavation to minimize the mixing of groundwater with the base when it is laid to the pond base.

TIP. The pipes for each bottom drain should be as straight as possible to reduce the friction and ensure a free flow of water through the pipe.

This website started with a booklet which I made up originally for the help of those members of the BKKS - South Wales Section who were intending to start building a koi pond, and as the website has expanded more information and articles from other people have been included. This is for general guidance only, and we do not take any responsibility for problems that might occur by following these ideas. It is important that you check out everything in your area, and check on local laws and rules that may apply.
