Catchment tank liner

[rrlovesbi]

$4800 is close to the price for a well.....

I've heard a well mentioned before.  Since we are in HA - Mountain View I assume finding water underground is not an issue.  Any thought's on companies to dig well?  

We have a 25 year old 10,000 gallon "doughboy" catchment (swimming pool), sitting on a concrete pad.  Catchment system is functioning, clean, and cover is about 4 years old and in great shape.  Cover sits on top of water and supported with some wire, but does not have a circus tent style support.  Have not cleaned the tank in over two years and still very little sediment at bottom or in filter.  However, we are wary of the non food grade liner and do not use the catchment water for drinking out of the tap.  We fill up 5 gallon bottles at county spigots in Kurtistown.  From research this water source is from an aquifer in Mountain View but it's great tasting water.   Also have a UV sterilizer and a 5 stage reverse osmosis at kitchen sink.  We use reverse osmosis water for coffee maker and cooking.  

Looked into replacing catchment with new galvanized tank, liner, cover, liner support for long term reliability and food grade liner. Spoke with Waterworks back in July and they sent me this cost for the materials:
The kit includes:
Tank
White Liner
Cover Support
Mesh Cover
Overflow Preventer
21'7"X3'8" = $3,018
10,100 Gallons

Stopped into Waterworks yesterday and person I spoke with confirmed price. I asked about installation costs.  First thing they said that I could save money by removing the tank myself since they have to bring to Kona landfill and I can bring to Pahoa or Hilo with no landfill charge.  Truthfully, I would rather have a turnkey solution and not add to the to do list for the property.  I asked about installation cost and was told I had to pay $90 for a site survey, (refunded if we use them - although I am sure they add it back in labor charge).  I asked for at least a range , for remove and install cost, and was told there was no range.  They have to make sure that they can get a truck in.  Said we have large trucks in without issue, and had photos of tank and site etc.  Said something about also having to bring in sand.  Why would you put sand on a flat level concrete pad?  Anyway, I left frustrated thinking that here they had a customer who had taken the time to come in to talk face to face (with masks and social distance) and I left with no additional information.

I also spoke with Hawaii Catchment back in July.  They said they use a higher quality steel and I recall they quoted about $6,500.  Which sounds very high.   Overall, will look further into a well.  The current catchment could just remain as a backup source.

Wells and cesspools don't mix.

Well, actually they do.

If we had a well we might use it for irrigation, but certainly wouldn't let our dogs drink the well water. I would certainly never pipe it into our house.

Your situation might be different, maybe you don't have a bunch of cesspools and septic systems all around and uphill from you.

Very few developed lots uphill or to sides.  However, had a nice conversation with Diamond Drilling and Pump in Keaau.  They have to dig down to sea level so it would be about a 1500 foot well and $$$$!

Diamond is the company we used, but we’re closer to the water table than you. 1500 feet is a long ways to drill.
