Open drains can be a cause of soil erosion, especially in rural areas when. Water traveling at high speed in drains will carry away soil and silt. The uncontrolled speed of the water can lead to excessive erosion of the sides of the roads making them narrow and impassable for wide vehicles.

Secondly, what are the disadvantages of surface drainage? A disadvantage of surface drainage is that it has a minimal affect on reducing the saturated subsoil occuring as a result of high water table conditions, especially where the source of the water is emerging from lower horizons.

Thereof, how are open drains harmful for human?

Open drains are harmful for human health as : i) It is the breeding ground for flies, mosquitoes and many other disease-causing germs. iii) During the rainy season these drains overflow and pollute the surroundings especially the water bodies and causes many water-borne diseases like diarrhoea, cholera etc.

Removal. Generally, drains should be removed once the drainage has stopped or becomes less than about 25 ml/day. Drains can be 'shortened' by withdrawing them gradually (typically by 2 cm per day) and so, in theory, allowing the site to heal gradually.

What is poor drainage system?

Poorly drained stormwater forms stagnant pools that provide breed- ing sites for disease vectors. Because of this, some diseases are more common in the wet season than the dry season. Poor drainage can lead to flooding, resulting in property loss, and people may even be forced to move to escape floodwaters.

Why is still water dangerous?

What is subsurface drainage?

SUBSURFACE DRAINAGE. A subsurface drainage system consists of a surface or subsurface outlet and subsurface main drains and laterals. Water is carried into the outlet by main drains, which receive water from the laterals. Submains are sometimes used off the main drain to collect water.
