I'm performing a shop drawing review of underground concrete storage tanks, to be used for firefighting.
We have six tanks arranged into two rows of three. 12-inch pipes connect the three tanks per row toegether, and one 12-inch pipe connects the two rows at one end.
It makes a U-shape flow path down one row, and back up the other.
Should two more linking pipes be added to form a complete grid, and allow more paths for water to flow?
Should these linking pipes be provided with vortex plates?
Thanks in advance!

Assuming the tanks are all in close proximity to each other, the additional pipes would not provide any benefit performance wise. The tanks should empty at an equal rate with the pipe layout you have.

Something not mentioned - Ensure that there are valves such that one tank can be taken out of service w/o degrading the rest of the system.

sounds like additional complexity with little benefit

Add valves to isolate. Looping is good. If it’s for fire fighting purposes, I d assume some sort of pumper truck which could create virtexind and an air column above the tank discharge, assuming a bottom discharge to get all of the water from each tank.

This post made an interesting point that when looking for an underground water storage, it is ideal that we look for an experienced plumber to help us get sorted. As they are experienced, it ensures that the right tank will be installed. I will definitely keep this information when I look to have tank installed for my new home.
