Water, Sanitation & Infrastructure

Labour and local materials for all projects described below provided by the respective communities as their contribution, knowing that they own them on completion. EBPP’s field team provide organizational support, transporting all the materials with their 4 WD Ford Ranger, donated by Standard Chartered Bank (Jakarta).

Access

When the project began, the village of Desa Ban was only accessible from the lower mountain slopes and the hamlets that now benefit from the sustainability projects were only accessible by trail motorcycles. In November 1999 EBPP began improving a 3km dirt track from the southern border of Desa Ban in the saddle between Mt Agung and Mt Abang to the hamlet of Daya. Volcanic sand excavated on site was mixed with cement and laid in strips to improve the road surface while Vetiver grass (Vetivera zizanioides) was planted on the verges to control erosion. Technical input was provided by EBPP and the villagers contributed the labour. The project was a success, creating easier and much safer access. The donor for this first project was Rotary Club of Bali Taman. So far, over 6km of dirt tracks have been improved making it possible for over 240 families to reach medical help, markets and other essential services that were virtually inaccessible before.

Building with appropriate technology

Guided by the EBPP team, the villagers of Dusun Bunga built the first community school using appropriate technology with locally-grown bamboo used as reinforcement, dispensing with the need for steel reinforcement. The building is 80 square metres with two classrooms, a teachers’ room, a library and a canteen and provides a purpose-built learning environment for the children. It also doubles as a vocational training centre for children, teenagers and adults. Work was completed in February 2001. Funding for this project came from Island Angels (Bali and USA).

Two other schools were completed in early 2003 using breeze blocks for the walls, due to difficulty gathering bamboo. The 164 square metre school in Dusun Pengalusan has 4 classrooms, a teachers’ room, a library and a canteen and was funded by The Community of Oppenhuizen en Uitwellingerga in the Netherlands. The 160 square metre school at Dusun Manikaji has similar facilities and is part funded by the Java St Andrews Society, (Jakarta) and Hard Rock Hotel (Bali).

Clean water reservoirs

With technical input from the EBPP team, five hamlets which lack a nearby natural water supply have built hygienic rainwater storage tanks. These use the same bamboo and cement construction as the schools. Rainwater is collected from rooftops via a bamboo gutter and then passed through a gravel and charcoal filter to clear sediment and bacteria. By August 2002, 24 tanks had been constructed. Each tank stores 4,500 litres and they provide the first-ever clean water supply for the people of these hamlets. Already their use has substantially reduced infant mortality and sickness. The donors for this project have been The Royal Society of St George (Jakarta), The American Women’s Association (Jakarta), and the Tierney family (Bali and USA).

Sustainable clean water supply from mountain springs

This project began in August 2002 in Daya hamlet, where the only water available is from remote springs or rainwater catchments – usually uncovered and very polluted.

It is a long-term project that involves monitoring the flow of water from each of the hamlet’s three springs over several seasons, improving water storage and surveying the water needs of the community to create an efficient and effective water distribution plan. The key benefits to the community will be more water for bathing and washing clothes and safe drinking water – something they have never really known. This project is funded by Thames Water’s Sustainability Committee.

Vetiver Grass: Bio-engineering erosion control

Vetiver grass, a non-invasive, clump-forming grass has been used successfully both to control erosion on steep tracks and to enable development of organic vegetable gardens on the very steep and sandy mountain slopes (see above). The closely planted slips of Vetiver grass rapidly grow into dense hedgerows with tough, fibrous root systems that can reach down to two or three metres in the first year.

Since we introduced Vetiver to Bali in 2000, we have helped many villas, hotels and individual householders to stop erosion on steep land, beaches and rocky cliff slopes. Click here for more information about Vetiver Grass
