2 inch to 3/4 inch fittings is a real blockage.
Will that drive you mad?

Doug, another interesting story.
I dont think I am angry either, just disappointed.
It was an eyeopener as well.
I did not throw them out, he explained he had mixed with some bad people and did not want them to come to my small farm place.
He chose to go back living on the streets, it was past winter.

I had a similar incident recently where I extended the hand of assistance, I finished up disappointed.
A couple living in a shed, I offered a home and 4 hours of paid work a week.
Charged them rent.
They paid rent ok, he had 3 car crashes, lost 5 pairs of glasses in 10 week.
He was bashed by her! and she tried to turn that around, I told her I did not believe her and she was lying.
She just backed off after that.
Cops came 4 nights in a row and finally took her away.
He was not capable of working, other than for 8 hours at the start because of her demands.
She had him getting milk at 2am in a rural area.
Just madness
He was not addicted to anything, but had to fix cars, walk or ride a push bike I lent him to shops 8 km. after the cars were wrecked.
He got an electric scooter, did not wear a helmet I lent him, crashed in loose sand and finished up in hospital.
They did not damage the house but left about $4000 of clothes, DVD's and  shoes.
And finger marks across the walls.
It was a shock to see how they lived and the decisions they made.
I met a person who work in welfare and she advised she was careful with whom she shared compassion.

Arvin,

The tank's nominal gallons are not the gallons it can deliver between starts.

What does this mean please?
Does it mean it consumes power all the time?
Also how does a variable speed pump system operate?
Does it run all the time and change speed to deliver more water when needed?
Does it mean power is used all the time?

CJ where is home it sounds interesting

 I dont think you will need to clean the settling tank, if you clean it with a pump.
I have seen a tank cleaning service, where they poke a vacuum type nozzle into the tank and remove a small amount of water with any sediment.
It seems to use about 20L of water.
That may work for you.
As mentioned bacteria build up does not appear to be an issue.

Thinking about your second tank, perhaps a plastic tank liner is the best system.
Its a heavy duty flexible liner that would be made to size.
My concern with that tank will be hard to make impervious.
Do you have a trick for that issue?
I have seen them plastered with a mixture, it may be available to you.
The total volume is great.

You do need a running flow of water for a ram to work, I will look for more data.
As for your water, the material in the water is actually in solution, not suspension and from memory will never 'drop' out.

I dont understand what you are actually trying to achieve?
What is this mean please?

Holly, sorry about a late response.

The internet made me very concerned about the house being under trees, contaminating the rain water. But isn't that just combatted by netting on gutters, first flush diverter, plus filters and UV sterilisation?

I see no issue with being under trees if you take the steps mentioned.
Rainwater is not being stored on the roof nor in the gutters.
Yes a bit more time needs to be spent checking and cleaning the system, that is all.

The 5000 gal tank cost (over $6K) is an overly big step for me right now, and a lot of those tanks are too tall to support rainwater catchment from the structures I have onsite.  

Dont forget tank makers who work in steel can make any size tank shape, tall squat, so you can order what you want or need.
I am comfortable with poly tanks, instead of galvanised tanks.
Big tanks are very hard to move, how will you do that?

WHAT ARE THESE For the IBC tote series,

For the IBC tote series, I am using nozzle splitters / hoses at the spigots to connect them,
