Hi all,
Just stumbled across this forum, some fantastic information here! I just had my well bored, and am planning the pump setup. I have some particular ideas, but the first well installer didn't sound too impressed. I wanted to run those ideas past the people here to see if I should push for this setup, or settle for a more conventional system.
The well will provide water for a single family residence (3000sqft), plus irrigation for a modest number of fruit trees. Currently the land is undeveloped, the well is the first part we are doing. I want to design the pump system, and install part of it now, to provide water for early landscaping irrigation, and for the development process. Site is located in Northern California.
The well is located roughly 600 feet from the house site, and is elevated about 140-160 feet. We need to provide fire-protection water (10k gallons I believe), plus domestic/fire sprinkler/irrigation water. My plan there is to eventually site 3-4 5k gallon tanks by the well site. During the development, I want to put a small 500 Gallon tank down close to the building site, which I will refill manually.

I like the idea of the Grundfos "SQFlex" line of pumps. The well location is perfectly situated for solar, and so the ability to run off solar, or via a backup generator, seems like a great idea to me. The solar panels would be only 20' from the well, with great Southern exposure, so installation should be pretty easy. In the short term, I would just switch on the pump during the day when I wanted to refill my temporary tanks. Eventually, the pump would be controlled by float switches in the 5k tanks (multiple switches, fire and domestic must be separate tanks). My calculations show that just pumping during the day (based on 5 hours) should be plenty, and I will always have the option of running a backup generator should we run into excessive water use.
That would also leave me the option of running the 600' of 220V line from the house up to the well when we do the final trenching and installation - but if I can avoid that extra expense, I would rather do so.
So, honest opinions please - is this a good approach? Or am I better off going with a more traditional (eg Gould) pump, just running a generator for my interim needs, and hooking it up to the household electricity in the final build. The house will be off-grid solar as well, so I would aim to somehow limit pump usage to sunshine hours anyway.
Also, if anyone has recommendation for Well Installers in the San Jose area, please let me know.
Anyway, thanks in advance for responses on this.
Cheers,
Chris.
