I gather HH is in a water shadow and there appears to be for some an issue with water prices for people living in some developments. What is the thought on installing water tanks? What sorts are available (materials), capacities and prices. Where is the preferred side of a house to put them ie: prevailing weather patterns?

If you are moving into a new house I would suggest that you put a water tank in the ground.
Basically the routing would be from the metered connection, to tank with ball valve, then domestic pump to house supply.
Do not forget to install non return valves after the pump and also a byepass around the tank - i.e. still maintain a direct feed from the supply in case of tank or pump failure.
The logic is simple.
Water supply is haphazard at best. Usually dropping or ceasing altogether during the day and usually recovering at night.
The above arrangement will serve as a buffer and hopefully get you through most 'crisis'
Not sure of size of your place and your needs but for example we have a 1600 ltr tank and pump that serves our restuarant and we never get a problem with water supply - cost around THB20k for digging the hole, concrete base, tank, backfilling, pump, pipework & electrics.
Tank was blue plastic - you see them everywhere but you can get st stl - but these are better above ground.
Good advice there.
I cannot understand how many housing developments, and private owners for that matter, will spend upwards of 800k Baht on a swimming pool, but do not consider water storage. It is well documented that Hua Hin has a water supply problem, but I guess that a lot of people come from countries that water shortage is unheard of. Not enough use is made of collecting rain water. It is not rocket science to install a workable storage system that will at least ensure that you have a reliable drinking water supply.
From my experience, underground storage is the best option. Concrete if you can afford it, PVC as an alternative. The "stainless steel" tanks that I have seen suffer from the TIT syndrome and are best left in the supplier`s shop. To some extent the life of any tank will depend on the quality of the water and its contaminants. Any system should be split up so that you have a couple of options, as Terry has stated. It just needs a bit of common sense and logic to design a workable, reliable system.

Tanks are a great idea but need a little bit of maintenance.
The good lady has the chore of climbing into our steel tank and giving it a good scub out and flush out once a year.Even with her rigorous filtering and management it's amazing how much sludge settles in it .
We collect only good heavy rains of freshly cleaned roofs and close it off once full. You should avoid allowing over flow to pass thru the tank proper as this increases the chance of contamination.
The system needs mesh screening at openings to stop mossies and vermin getting in.Stainless steel is best, avoid shade cloth or fibre glass mossie wire as they break down and get into the tank. Not too good if you use the H2O for drinking or cooking as we do.
Shading from the sun helps to keep the water much cooler. We have tum leung ,marla and passion fruit vines sprawling over the tank for this reason.
In ground concrete tanks need properly sealed poly liners to prevent infiltration thru the tank wall.They usually develop cracks in them especially in the less stable reactive clay soils found in much of Thailand
