Splitting a reservoir of water 1

[JohnnyBrav0]

I need to put a barrier wall in the water reservoir (not too big in size). What materials (polymers in particular) would you recommend?

 

[LittleWheels]

Potable water? Durability required? Existing reservoir material and waterproofing method? Lots more questions.

Water is a normal drinking water. Barrier will be installed for few months and then removed. Reservoir is concrete lined. Barrier is going to split the reservoir in half and prevent water from mixing between two halves.

No differential in head? Flexible membrane certainly sounds possible.

no head difference. What kind of membrane can I use so that there is no mixing of water between two halves of the reservoir? I cant think of a way to make sure there are no leaks along the wall...

There are several materials that should work. Your situation isn't too different to loose-laid waterproofing membranes for potable water reservoirs, except you'd be suspending or floating it. Sealing seams and joints is always a problem, together with abrasion/ tearing, but you don't have long-term durability concerns. There are always points in concrete reservoirs where their loose liners finish, such as outlets. You just have a longer edge between liner and concrete.

Google "pond liner" or "waterproofing" and "potable" for some ideas and materials.

Interested to know why you want to divide a reservoir and have the same height of potable water on both sides. Are you doing something on one side and confining contamination?

Dave,
you are absolutely right. I need to split reservoir to do some experiments on one side and compare it with regular water.
