RE: strainer installation
If your tank contents can be made free from delaterous materials, scales, salt chunks, or your intakes are well placed or filtered, you might not need one, but in which case its always a good idea to make a provision to have a strainer installed at a future date if you can't buy one now. Operations will probably put one in some day. Tip: If you at least leave a provision for installation, maybe you can still keep your job when it happens.

RE: strainer installation
I have seen stainers clog, colapse, and get sucked into the pumps.
I would suggest that you look at two stages of inlet protection. A large coarse strainer, and then a finer one after it if it is needed.
Witha 20" intake I imagine that your pump can handle some sizable debris without damage. Check that out first.

RE: strainer installation
1. Why do I need a strainer?
2. Why don't I need a strainer?
Question 1, because there is the likelyhood of solids gaining access to the water tank, therefore I need a strainer.
Question 2, because the water tank is enclosed and no solids are able to gain access to the tank, therefore I don't need a strainer.
I see no other reason that needs any consideration.

RE: strainer installation
In that time, do you expect enought "stuff" to go through the pump to cause it trouble?
If the answer is not much and not much, then I would not use a strainer.
If the anser is yes and yes, then I would suggest you get better water.
