A visit in Sambirenteng. Minutes of the meeting on 15 April 2010
Last week a small group of us (Annett, Nyoman, Beate, Johann, Pak Suwenten and me Burgel) went to visit the building site of Holiway in Sambirenteng, north east coast Bali. Thank you Maria and Stefan for inviting us!
It's a large plot of land, a part will be built up with villas and the other part with bungalows. The concept is to create a place for "holidays with sense" in an environment friendly surrounding. Therefor buildings like seminar rooms for different kind of seminar and body work, swimming-pool and installations for waste water treatment and alternative energy are planned.
First we inspected the land protecting wall towards the sea. "Geotextil", a 100 year lasting material, is put in layers in that way, that soil is not washed away (and it even catches sand towards the land). To hold everything large volcanic stones are put to a wall with a slope. It is important to arrange the stones in the right way, then it will last a long long time. No concrete at all is added. For better protection vetiver grass with its very long roots is planted in a long line the whole length of the retaining wall. Hopefully the place is not too salty for this excellent land protecting plant.
Besides "geotextil" another interesting materiel is used there: a kind of styrofoam with both sides covered with thin aluminum. This is used as roof isolation to keep the coolness inside the rooms and to reflect the heat from the sun. Air conditioning is planned for the rooms, so with this isolation for sure energy will be saved.
Electricity from solar energy is planned for machines and devices which are used during day time, such as washing machines and pool pump. So, no need for batteries.
Johann recommended "Solahart" to make hot water with their solar water heater. The cheaper product line from Solahart is called "Handal".
For the waste water treatment they use the system from "IndoBio". 5 houses are joined together for one 3-chamber-system. One chamber has aerob bacteria, the other one anerob bacteria and the last one is with ozone. In the end the water is 95% cleansed and it will be used to water the garden. Too much toilet paper causes problems to this system. Unbleached toilet paper can't be found in Bali.(Does someone know where? Please tell us!) Therefor toilets with integrated hygiene "wiping" with water in stead of dry cleaning with paper are already ordered. Hopefully the future guests and owners will understand.
A nice lunch filled our hungry bellies before we were leaving this interesting site.
