Water Supply | Sanitary Well

Posted on: April 2, 2008

Environmental Health – Sanitary Well

Sanitary well can be defined as ‘a well which is properly located, well constructed, and protected against contamination with a view to yield a supply of safe water’.

Constructing a Sanitary Well

These should be taken into consideration in order to construct a sanitary well.

  1. The well should be sunk in ‘good’ soil and should be sited high enough to prevent flood waters from entering it, also located far enough from latrines to prevent contamination.
  2. It should have casing (lining) which is made of brickwork or concrete; it must be water-tight at least 3 meters (10 feet) deep so that the water in the well is only from the soil.
  3. It must have parapet of sufficient height above the ground level at the mouth of the well to prevent anything from falling into the well. A cover should also be provided.
  4. An apron (platform) made of concrete surrounding the well can further prevent seepage of water from the surface into the well. The apron should be sloping with a drain incorporated.
  5. Ideally, a pump should be installed. Parapet is not necessary if the pump is installed.

An ideal well is a sanitary well installed with a pump.

Sikap Kita Terhadap Sesama Daie

Sikap Hizbut Tahrir sendiri terhadap gerakan-gerakan Islam lainnya setidaknya tercermin dari pernyataan Amin Nayaf , salah seorang tokoh Hizbut Tahrir –ketika beliau memberikan jawaban atas tuduhan terhadap beliau yang telah menyebarkan pemikiran Mu’tazilah: “Janganlah kalian mencoba untuk mencari permusuhan atau mengarah pada permusuhan terhadap gerakan-gerakan Islam lainnya. Kita harus waspada terhadap pihak-pihak yang mencoba untuk memecah-belah gerakan-gerakan Islam. Kepada merekalah seharusnya serangan itu dilancarkan.

Reminder to All Muslims around the World

“Say: If it be that your fathers, your sons, your brothers, your mates, or your kindred; the wealth that ye have gained; the commerce in which ye fear a decline: or the dwellings in which ye delight – are dearer to you than Allah, or His Messenger, or the striving in His cause;- then wait until Allah brings about His decision (ie. Torment): and Allah guides not the rebellious.” [TMQ Surah At-Tawbah: 24]
