Storm events and monsoon ...

Storm events and monsoon season will cause soil erosion, surface flow carrying eroded soil/silt, contamination from overflowing drains, sewers, leaching from garbage dumps, leaching of chemicals/fertilisers from fields, fecal contamination, contaminations due to open defecation animals dungs will enter the water sources. It will increase the flow in drains and causes floods and flash floods and affecting the drinking water sources with high contamination and high turbidity with debries and silt load. Consumption of such affected water can cause many health deceases, gastroenteritis and epidemics episodes in the affected localities. These can’t be avoided without turbidity reduction and disinfection of affected water sources. Water quality will be affected badly.

Management:

1. Proper drainage system shall be planned to carry the storm water load, planned plantations for avoiding soil erosion, gutters with inspection chambers carrying storm water shall be constructed. Open defecation shall be avoided by awareness camps among the communities in the localities, no over flow sewers shall exist. Garbage shall be dumped properly following solid waste management techniques to avoid leaching and flowing with surface water.
2. Wait for reduction in turbidity level for proper functioning of water treatment plants avoiding choking of the system.
3. Water shall be get filtered through cloths, charcoal, sand and keep for stagnation to settle down the silt load.
4. Chlorination/Chlorine tablets may be used for disinfection followed by boiling the water for drinking.
5. Drinking water sources shall be sealed properly before monsoons so that such episodes may be avoided.
