Using your tap water for changes is always an iffy thing and is really specific to the place you live and the quality of water you get there. I know of people who are able to use their tap water (after treating it ofcourse). I'd recommend testing your water for ALL chemicals that might affect the tank. If they check out reasonablty ok, you might be alright. If the parameters do not check out, I'd strongly suggest against it cos it will create all sorts of problems in your tank.
One thing you could do since there's no places for you to buy water at is to invest in a Reverse Osmosis (RO) unit. You can get one for about $150-200 here in the U.S. Once put through the RO unit, you should be able to use your tap water.
You will of course, need to buy the salt for the water and get the right mixture together for use in the tank. If you're not familiar with the quantities, I'd recommend reading up on the subject thoroughly.
Cheers!
