Brought in a backhoe on Monday to dig the hole for the cistern (fresh water holding tank) and the ditch for the wall foundation on side of lot. The tank is 2800 liters and cost $4000 pesos (less than $300us). At the bottom of the pit is a cement floor with rebar. They decided to put in 3 castillos (support posts) to tie it together. The form for the top is made a few feet away, also rebar reinforced. We'll see how easy it is to move next week.
It was the first time these guys had installed a plastic cistern (usually just a block box) so the plumbing presented a few new problems. We had conversations about venting, where the pipes go and height of the top above the tank. They had no problem with pipes coming out the top - but the top will be part of a patio. I talked them into another ring of block so pipes exit the side.
Next day I brought out our plumber and he had us turn the tank around so the 1" fitting aimed at where the pump will be. He also mounted the street shutoff on the front wall of the lot, made a spicket for garden water and ran the line back to the cistern. We then waited 'till after 1 pm for city water to start flowing

I'm curious about the choice of plastic cistern... are you concerned about contamination? or leaking? or ?? what type of plastic is it?
Are you collecting roof water or storing well water? I love the idea... we'd be well to do more of this in the US...
Here is the RotoPlas site but in Spanish. Thought I ran into one in English. It's the most common here.

No it's only to hold street water and then be pumped to a tinaco (roof top tank) for gravity feed
I forgot to say ... that when it rains here, it really rains. We have hurricanes and sometimes flooding. Plastic is really more secure if the water table is high
Using a plastic cistern keep away problems about water contamination, and is a product that u maybe never back to buy again ir your life, I think who have a best quality of water is most important than the fact of be of plastic.
