Sanitation near Jakarta

I am a watsan engineer based in Indonesia, Jakarta and am faced with a difficult situation. Below are the details:

  • Location: Tangerang (30 Km from West Jakarta, Indonesia),
  • Disaster: Flood with Water level reaching 70 cm -Number of people affected: 500 People, Number of households/houses: 99 (1 well per house), -Project scope: To provide sanitation for the all village under SPHERE standards (i.e. 25 latrines with adequate distance between latrine and water sources/well),
  • Problems I am facing:

a. lack of time : 1 month to complete the project b. lack of space : no space in the village, c. 5 m distance space max between houses,

Solutions I can think of :

  • Using bio-filters but we got problem such as price, volume, etc. I am in the phase of emergency so need to take into account Sphere standards, using biofilters ok with Sphere or not?)

  • Using the composting latrine but the maintenance is difficult for community.

Please give me advice to solve my problems in the site.

Regards,

Sigit

As is often the case, the standards called for in Sphere may be rather better than people in the area are used to.

My starting point would be what were the people using before the flood. Perhaps they have collapsed or been flooded but that is what will work, especially if they can be improved.

Generally individual household latrines are much better maintained than communal ones but you have a problem with both space and proximity to wells. Is a lined pit/septic tank possible with periodic pumping out.

Don't go for composting toilets if people are not accustomed to using and maintaining them.

I have dealt with a similar problem - i.e. high ground water table, nearby drinking water wells, not much space.

The solution we adopted was to bury 2000 litre plastic water tanks with suitable ballast to prevent flotation. Pour flush latrines with the pan about 500mm above GL discharged into the tanks. The tanks had a high level emergency overflow to soakaway and a vent stack. A local entrepreneur was paid to empty the tanks on a regular basis and we think he also made money out of selling the sludge to farmers.
