Back in December we were so immersed in all the planning for Cuca that we hardly realized that the weather in Bali was gradually changing. Summer had been amazing; the cold wind from Australia’s winter brought perfect temperatures and the driest months of the year. The raining season started gently in November but by mid-December was unstoppable. One of those first rainy mornings we happened to pass by the restaurant site and were shocked by the horror scene: our beloved garden lounge to-be was flooded and this was only the beginning of the monsoon season!!!
Frantic calls and emails followed: we had to address this problem before starting construction!!!! During the next few days we found out that the situation was even more critical. Bali infrastructure leaves much to be desired and there isn’t a proper system to get rid of any excess water even if we managed to collect it within our land. We had to come up with a clever solution and our contractor was the only person we knew who understands about pipes, water and geology. This is his master plan, right now being implemented:
The idea is to let the rain water infiltrate easily into the soil to reach the “water table” (natural water level in the soil) instead of just running-off on the surface that is what creates puddling and floods on the garden.
To facilitate this, infiltration wells are dug by removing the soil within. A “geotextile layer” is then applied to filter the water and prevent the sand from going through into the well together with the rain water, what would cause landslides.
The well is then filled with rock piles kept in place with a steel string cage. The rocks let the water go through to reach the “water table” and are covered with stones and soil to grow back the grass.
This system is supposed to be highly effective but have limitations in case of extreme rainfall as it would not work when the water tables are full and the water has no place to go…
Anyway and as you can guess, our contractor is now our hero. He has rescued Cuca from the floods and we will be forever grateful.
