Our neighbors have always bathed with the local groundwater and drunk rainwater, but all that is about to change. The municipal water main is coming. Just yesterday, the superstrong worker dudes used long poles with cylinders on them to dig deep holes into the clay (Bangkok earth is clay) next to the "road" next to our house (actually a sidewalk-sized road that permits only pedestrians, motorbikes and bicycles). They then hoisted up these 6-meter long cement polls and dropped them into -- ploop! -- into the holes.
With the cement pole balanced perfectly on this cart like a seesaw, it is rolled into the forested inner reaches of our neighborhood from the main road (a real road for cars, about 150 meters from our house).
These were not here Friday and were all dug and put in place Saturday morning, before noon, which is when we arrived. The workers will then pour a cement block with a half-moon cradle for the water main pipe to rest in.
