The HydroTimor weBlog

The penstock, the pipe transporting the water from the dams to the power station, are approaching the dams.

The rainy season near, workers are digging hard to complete the ditches so that the penstock may be laid and covered again. Hard rain will make this work difficult, and may lead to delays… To add to the challenges, the terrain close to the dams is very steep and requires digging through a hill. Thus, heavy equipment is used, like this excavator, which digs a deep trench through a hill just before the penstock will split into two smaller pipes leading to the two ponds.

The intake ponds in Garuiuai are progressing rapidly. These two ponds are collecting water from the springs in Builai and Wainalale.

The construction done now is of a small earth fill dam at each spring. This will create a small pool in order to raise the water level sufficiently for collecting the water into the penstock (the pipe to the power station about 187 metres below). A concrete base containing technical parts, including the intake connecting to the penstock, is more or less finished. The rest of the dams are made by compacted soil with a core of ironwood. The dams are sealed with geotextile, with stone pitched surface.

Things are happening in Gariuai! The penstock (pipeline) is extending. The Powerhouse is shaping up. The intake ponds construction has started.

There has been huge progress in constructing the powerhouse. This is critical work, demanding accuracy and high-quality craftmanship. The building will soon hold the turbine, connected to the end of the penstock and the generator. As even small errors here may be dangerous and destructive, the HydroTimor team is following the work closely to ensure compliance with the plans. They report that the work so far has progressed well, and are impressed with the local construction managers, saying this proves that local managers may do high-quality work. Good for our future as a nation!

Construction of the powerhouse is progressing well.

HydroTimor has measured the waterflow of the Magapu river for more than a year, assessing the possibilities for building a small hydropower plant about 6-7 km outside Atsabe town. The idea is to build a small intake weir uphill, and lead the water through a canal to a pipeline (penstock) connected to a downhill power house. The measurements are not yet finished, but indications so far is that the plant may produce somewhere between 10 and 15 GWh annually.

A hydropower engineer from Norway, Are Kiel is in Atsabe now, measuring the landscape and finding a possible path for the canal. His findings will later be posted at the website, together with more info on the project. We hope to see the project started next year. The electricity will initially benefit the local communities, and later (as more power lines are stretched) that the plant will contribute nationally, delivering to the national grid.

We are preparing an info package on the Iralalaru project, to be done by Kassius Klei Ximenes from HydroTimor (photo) and Basil Rolandsen from the Bouvet Foundation.

The info package will consist of a brochure (ref the Gariuai brochure), as well as a DVD with video and supplementary information. The brochure will be finished during October, while the DVD is scheduled for late November.

This info, together with adapted video clips, will also be posted at the web site. We look forward to inform more about Iralalaru Hydroelectric Power Project, as the plans are now being finalised before tendering. Work should start next year, to be finished in 2011.

Respect for traditional beliefs is strong throughout the country, including in Gariuai. Objects like springs, stones and trees may be sacred homes to a god, or “lulik” in Tetum. Offending the lulik causes problems both for the offender and for the people living in the area: Offending the lulik of a spring may cause the water to dry out.

The Gariuai powerhouse is situated at a sacred site, next to the lulik in a large stone. To secure a successful construction of the house, as well as good health for the workers and the future of the local people, we performed a traditional ceremony in order to obtain permission for the construction from the lulik. Such ceremonies are often used when cultivating new land, building a new farm, planting crops and for other purposes.

The ceremony was performed by Mr Arlindo Sarmento, and included offering a chicken, wine and betel nuts. Blood from the chicken and wine was spilled on the powerhouse site, and the nuts buried beside the lulik. Then the bird was prepared and eaten by the participants. Thus the project is blessed and it’s future secured.

The ceremonial master, dressed in traditional garb, cut the throat of a chicken as part of the ceremony to obtain permission for the construction of the powerhouse from the lulik.

The power house site has been cleared for vegetation and the digging has started. Steel trusses, doors and windows are under construction, either at the Salesian training centre in Fatumaka, or in Dili. All drawings for the construction are received. The work is supervised by Mr Arlindo Sarmento, a Dili based contractor of ViqZum/Lemorai Hamutuk.

The power house will contain the turbine, generator, transformer and other necessary equipment. It is expected to be completed during September, and the turbine to be installed shortly after. Final testing will however not be possible before the completion of the penstock, due early 2008.

It may not be a real power station, but at least there is a solar panel installed at the power house site now…

HydroTimor’s Kassius Klei Ximenes assisted by Construction Manager Vasco Pinto installed the panel, which charges a battery to supply electricity providing light to the site office and the staff living quarters.

Solar power is a resource HydroTimor will install another place, as well: The Bereleu primary school near Liqidoe will soon receive solar panels, which will help students finishing their home work, as well as benefiting the staff preparing for next day. The school has been very helpful to HydroTimor during water measurements in the area, and we thought this might be a nice way to say “thank you”. They seem to agree…

Heavy rains during March to May led to some delays, affecting both digging of ditches and transportation of pipes, but the work is now progressing satisfactory again.

The penstock (i.e pipeline transporting water from the sources to the generator) are divided into two sections: The larger section, consisting of 400 mm pipes will be 1440 meters long, and now about 820 meters are completed, including a small pipe for signal cable. The smaller section, consisting of 250 mm pipes connect the larger pipes with the two intakes, a total 900 meters (one stretch of 350 m and one of 550 m).

The larger section is expected to be completed during October, and the smaller stretches probably not until early 2008. The terrain is very difficult, the work is demanding, and the completion will depend on the onset of the next rainy season…

Due to the heavy rains recently, there will be delays in the site work.

Thank you for checking out the weblog! It is to be a part of the HydroTimor website, and we aim for it to be launched by the beginning of April 2007. Welcome back!
