@Sui: Pumps are - notoriously - the most vulnerable/unreliable component of ANY water collection/movement system.  We've seen so many - including brand new - systems fail, simply because of them. A major/multinational field study, of about 3 or 4 years ago, found that some 40% of recently installed  community central water treatment/dispensing systems, were having to be abandoned by their village recipients; almost always because of poor choices of key components + overly technical designs/engineering (& failure to pre-arrange long-term maintenance).

To avoid this common & egregious error, we consulted with a key field technician for a major int'l. company, that both produces & distributes components for such systems.  They have, we confirmed, 2 major positive advantages connected to their equipment:

1) A high level quality control/endurance standards guarantee; 2) Worldwide parts & components  distributors, on every continent, that can quickly & reasonably provide either replacements or repairs.

I have their catalog & contact info in my files, if this alternative is of interest to you/your group.

I also have some directions on how it may be possible to totally avoid pumps in some applications, with an alternative system layout: Which, of course, makes both installations & long-term maintenance a much cheaper/simpler matter.

You can contact me directly for details, % seamus_purewater@comcast.net.  Hope this is of some assistance. Regards, JSB
