I'm guessing you meant the company that made a septic tank from those
individual tanks is where you got those 2 tanks.

They were two individual tanks, not even close to matching. Doubt if they
were even made by the same company by the looks of them. These come in
many shapes and sizes. No concrete is involved. I got them from a company
that installed septic systems, not manufacture tanks. Do a little perusing
of fiberglass septic tanks and it may become more clear to you.

Don't really need fiberglass septic tanks for collecting rain water for
irrigation.
