SAS (Servicos de Agua e Saneamento)

Location: Delta Nova

Type of water: Underground Water

Commercial Water

Visited We Moris plant but due to

companys confidentiality hence they did notshare any info

However from random interview withcustomers, they consume 3-5 gallons ofwater/week*

* Vary from one household to other


9/14

Private water

Private water: water which community dig by

themselves

Due to poor water distribution, manycommunities choose to find their own water

sources. The sources are: Well, Mota Pompa,

River water and ect

Some even illegally get their water(leakage)

So where does wastewater goes?

In Timor Leste, as far as I know, there are no

Sewage Treatment Plants(STP) so all of thecommunity discharge their wastewater to:

Septic Tank

Canal

Rivers

And ended up in Dili Sea

12/14

Conclusion

Water sources: Government, Private and

Commercial

Water Treatment Process: Coagulation,Sedimentation and Rapid Sand Filter

Wastewater discharge to: septic tank, canal,river and sea


13/14

Recommendation All the water treatment process requires power supply but in Dili there is

always power bleak out hence it recommend to have their own backup

power supply Inside rapid sand filter, they need include adsorption layer (activated

carbon) to remove dissolved organics

Sludge from sedimentation tank need to have proper disposal ordewatering instead of discharge directly back to river

Community can have another option for source of water: Rain WaterHarvesting

Improve water and irrigation canal in Dili

Law enforcement to prevent river and canal pollution

Construct Sewage treatment plant

Law and regulation enforcement

Public awareness
