Answer:
(Fatwa: 50/42/D=1434)
(1) According to the Shariah, there is no direction fixed for septic tank. There is no harm if it is in western corner as it carries no sacredness rather it is attached with western direction as we turn our faces towards it in salah, and it is forbidden to turn face or back in that direction while using toilet.
(2) According to Shariah, directions carry no importance in the position of rooms; we can build it as per our ease and availability. There is no harm if any direction is preferred owing to the sun and air. Keep the position of toilet in such a way that the face or back is not towards Qiblah while sitting in toilet.
