DEWATS for Low-Flush Integrated Sanitation System: Applied at Mariae Grignian Louis De Monfort Orpha
The orphanage, which established November 30 in 1996, occupied by 50 children, age from 10 months up to 16 years old. There are 6 sisters and 8 staffs who stayed there to help taking care and running the orphanage daily. Due to the nature condition in Kupang and East Timor in general, water are very scarce. The orphanage only rely on a shallow well with 20 meter depth which they hauled everytime using manual lifter. As a consequences, only limited water can be used for domestic purposes. Sanitation business also a bit different with the other part of Indonesia. Although they have water scarcity, but for sanitation business, they still use water as anal cleansing.
Last September 2008 BALIFOKUS received Small Grant from the German Embassy to improve the sanitation system in Mariae Grignian Louis De Monfort Orphanage located in Sikumana, Kupang City, East Nusa Tenggara. Due to some technical challenges, the project had just finished last March 12, 2009.
The orphanage also provide 3 times meals for the children and the adults. They use firewoods for cooking. Every week they must buy firewood about 100,000-150,000 IDR, so in a month they could spend about 400,000-600,000 IDR only for firewood. The orphanage also operate an elementary school and provide life skill for the young people. The orphanage raised free-range chickens, pigs and goats to support their economy and the children’s nutrition.
In response to the limited water supply and teh need of the orphanage, BALIFOKUS helped installed a modular DEWATS (Decentralised Wastewater Treatment System) made from fibreglass consisted of one unit of digester module and 7 fibreglass settlers and anaerobic baffled reactor made by the local fibreglass company based on our design. The total costs for this modular low-flush sanitation system is approximately 91 million IDR.
The animal dungs and black water from the toilet supplied to the biodigester to produce sufficient gas for cooking. The effluent water from DEWATS plant safely discharged to the environment and can be utilised further for irigation purposes to grow crops and corns.
The project impact for local population are as follow:
Improved the sanitation condition of the orphanage
Increase the knowledge of the sisters, staffs and the children about sanitation issues and the DEWATS simple technology, how it should be operated and maintained.
Less expenses spent for firewood. After the first month use of gas from the DEWATS plant, the sister’s expenses on firewood reduce about 100,000 IDR. The expenses expected to be decrease more in the coming months after the system up and running for 3 months.
Increase local people capacity especially for technical labours and masons as well as the local manufacturers.
The orphanage could be the role of self sufficient model for other orphanage in Kupang and other areas especially in water-less regions.
