In the initial stages when the water is pumped out fine sand comes in the tube well with the water and consequently a hollow or cavity is formed at the bottom. The bottom of the cavity for some thickness is thus made free of finer particles. After the cavity formation only clear water enters the tube well.

The schemes have been categorized broadly into six major types: (1) Dug wells (2) Shallow Tube wells (3) Medium Tube wells (4) Deep tube wells (5) Surface flow schemes and (6) Surface lift schemes, the first four categories belonging to Ground water and the latter two under Surface water schemes.

Two broad classes of well are shallow or unconfined wells completed within the uppermost saturated aquifer at that location, and deep or confined wells, sunk through an impermeable stratum into an aquifer beneath.

Boreholes and tubewells are important adaptation technology measures for providing a domestic water supply during times of water shortages and drought. They extract freshwater from subsurface or deeper groundwater aquifers.

Bore wells are drilled in hard crystalline rocks whereas tube wells are drilled in soft sedimentary strata especially along the coastal stretch. In bore wells casing pipes are used only up to the bed rock while tube wells have pipes lowered up to the full depth of the bore.

Answer. Tube wells are the wells from which we pump out the water through a handle present on it. Tube wells can trap water from deep strata. In dug well water is collected from water bearing strata.

The main disadvantage of using tube well systems for irrigation purposes is that it leads to depletion of the groundwater because of which the groundwater stock or pool may get exhausted and ground water is only used as a source.

The results showed that all tube-well water samples contained zooplankton and bacteria. Results for some of the parameters were outside the accepted limits recommended by the World Health Organization for drinking water. It is concluded that water from tube-wells should be treated if used as drinking water.

A well inspector takes water samples and sends them to a lab for analysis. Water quality testing can cost an additional $100-300 depending on the type and quantity of tests your inspector orders. Often, septic tank inspectors are also certified to conduct well inspections.

Do’s and Don’ts when maintaining your septic system

1. Regularly inspect and maintain your septic system.
2. Pump your septic tank as needed.
3. Keep your septic tank lids closed and secured.
4. Be water-wise.
5. Direct water from land and roof drains away from the drainfield.
6. Landscape with love.
7. Keep septic tank lids easily accessible.

Too many solids flushed down your toilet will make your septic tank fill up very fast….You should not put these items into your commode:

• Cat litter.
• Coffee grounds.
• Cigarette butts.
• Dental floss.
• Disposable diapers.
• Earplugs.
• Sanitary napkins or tampons.

The long showers will put more water into your field which can over load your field and excess water/effluent can surface. If you live a lone and don’t use a lot of water otherwise you probably aren’t hurting the septic system too much.
