I think that the dependency could be declared using org-depend but with
the BLOCKER keyword instead of the TRIGGER one. To allow the elements to
still be set to DONE, you could use the NOBLOCKING keyword.

Then, in the agenda view, you could use the org-agenda-skip-function
variable and put something like org-depend-block-todo that would
indicate to skip the blocked items. Sorry to be to lazy to write the
code here...

The outline would look like this:
--8<---------------cut here---------------start------------->8---
* TODO Pay water
  :BLOCKER: checks
* TODO Pay electricity
  :BLOCKER: checks
* TODO Get new checks
  :id: checks
--8<---------------cut here---------------end--------------->8---

Having at the same time BLOCKER and NOBLOCKING appears a bit confusing
to me. May be it is not a so good solution and an org-mode guru will
probably correct me :-).

Hoping this was useful.
