Cooling Tower Question
What are the Pros and Cons using One cooling tower with multiple cells Vs. individual cooling towers?
Either way it feeds one common building riser.
Double towers often have a single drain. So if you need to drain one side for service, you may have to dam-up the water on the other side, then manage the level controls too. Otherwise, they should be more cost effective and mainly have a smaller footprint. Similarly, if the drain gets plugged up, you lose capactiy on both cells.
I would make sure that you can isolate and balance water to both sides of the tower. This way, if you do have a fill collapse of damage, you can isolate that side and at least get partial capacity while waiting for repairs. Some double towers just have a single valve to distribute water to both sides of a single cell.
Pros: Cost - twinned towers are cheaper than their single counterparts for the capacity.
Cons: Sharing of water basin means cannot shut down 1 cell for cleaning/maintenance usually means losing two.
If it is a large plant, where there are, say, 6 cells needed, I see no problem, and would actually recommend the twinned variety. In that case, taking 2 cells down to work on 1 is not as major an issue.
To add more into the fact is there are Three (3) Marley 550 ton each towers and There will be filtration system. Even if they combined will have separate drains, valves and power.
Is there any performance issues other than cleaning and leveling?
It does depend largely on the tower specs. Some even have multiple drains. Others, as I've mentioned, have a drain towards the center and you may have luck using sandbags to block off one side.

Are they forced or induced draft towers?

Treat the water right for scale, algae, corrosion, and legionella.
- Electricity makes refrigeration happen.
- Refrigeration makes the HVAC psychrometric process happen.
- HVAC pyschrometrics is what makes indoor human comfort happen...IF the ducts AND the building envelope cooperate.
A building is NOT beautiful unless it is also comfortable.
they are induced draft towers.
