Are you smarter than a 6th grader?
In response to 141365: North Kona "water crisis", posted by Dan A on Saturday, 30 September 2017, at 8:40 a.m.
Absolutely correct and they get a raise/bonus for doing such a good job in the crisis.
This was once in a lifetime event.
Now lets do the simple math. We have 15 wells and a pump lasts about 5 years and it takes about 8-10 months to do a replacement.
A statistician will tell you that we can expect a failure of 5 or MORE wells every few years. We can also go a couple of years without a failure. It is just simple statistics but the average is 3/year not working not the max or min. We are replacing 5 at almost the same time so in 5 years there is a high probability of a similar condition. The mitigating fact is all the wells are not high capacity so smaller well failures can be hidden from the public.
They need to do a number of things. Monitor the well electric usage because it predicts failure. Purchase their own rig to pull the well so they can do the maintenance on it. Find a way to use equipment that has shorter lead times to replace the equipment. Replace working pumps that exceed their predicted lifetime by about 50% or whatever experience shows.
A comment in West Hawaii Today someone tried to push part of the blame to HELCO for dirty electricity. He needs to realize that starting a BIG pump motor is creating dirty electricity and there is little the power company can do to protect itself from sudden huge load changes and all the customers suffer with power surges/sags.
