Water Filtration & Electric Gate Opener

[chiang mai]

We've just moved into a new (old) house and we need some bits and pieces, I foolishly posted this in the DIY section but Chiang Mai specific answers are needed:

The First:

The first on my list is installation of a water filtration system for the entire house, you know, one of those space ship devices that sit outside the back door! The house is on a municipal water supply

Can anyone recommend a particular make/supplier/source, the house is only two bed two bath, 150 sq metres, two occupants plus dogs!

Second:

We finally have a drive way and garden of our own again, trouble is the wheeled gate to the drive is manual, that has to end!

Can anyone recommend a product/installer to install am electronic gate opener?

As always, any sensible feedback is very welcome, with thanks.

Lanna Water shop on Changpruek Road (across from the university on the left headed N to the super highway) is good for various filters.
