The presence of water increases the vastu strength of the property. A water reservoir that is visible at the north-east part of the plot increases vastu strength. Also water will be available always. According to vastu shastra, any under ground construction, including that of a well in the north-eastern part should not touch the wall or compound wall of the house. No pit or well is allowed straight in front of the main door.
The position of it is determined by taking the area of the house in to consideration. If the position of it in the neighborhood is not in the north-east direction, it should be not visible and for that compound wall should be built. A well should be dug by following the above said things taking advice from a Vastu acharya.
