Septic Tank Purchase

[simon43]

I finally made a start on building my little resort. Sourcing most building materials is not a problem, but I have a problem with my septic tanks! Because our land area is rather small, and we cannot install a large leachfield (soakaway), we need to use septic tanks with 2 or 3 chambers.

The common septic tank that I can buy anywhere is the black plastic type, 600 or 1000 litres. But I'm looking for the type which is typically 2 metres long by 1 metre wide/high, and made of ribbed plastic. It contains 2 or 3 chambers so that aneobic treatment of the waste is better than a single tank, and so the leachfield can be physically smaller.

I could just buy several separate tanks, but the multiple-chamber type is neater and has the intake/outlet pipes and baffles at the optimum height.

Has anyone seen this sort of septic tank in Phuket??

Thanks
