Deep shafts are being sunk into the klongs to connect to sewer lines being installed deep below the klongs. This is a major project that has been going on throughout the city since the early 1990's.

This page shows construction along a section of klong that starts 20 meters north of Suthisarn Road. Here the klong is little more that a drainage ditch and is dry most of the time.

Below (C): During the 1990's, most of the smaller drainage klongs were shored up with concrete. Some have walkways along them.

Left (A): Looking down into one of the many large shafts sunk into a small klong.

Above (A): Workers in their underwear working on the sewage pipes that run deep beneath and parallel to the klongs.

Above (D): Juncture where a smaller klong runs into a larger one.

Above (E): One of the smaller branches that runs behind the RCA II buildings. Most of the smallest klongs are little more than drainage ditches/sewers.

(G): Typical flood gate that includes grates for pulling debris out of the water (right) and a mini-crane (above) for dumping the material into trucks.

(H): Beyond the floodgate the klong is full.



(I):
Klong life: A beautiful place, but the stench is overpowering (this photo was taken right after Loy Kratong, so the water is filled with kratongs).

(J): Before the klong reaches Weepahwahdee Rangsit Road, a major juncture is being constructed that connects the local sewers to a city-wide system.

(K): One of the massive circular shafts at the juncture that routes the smaller lines into the city system.

(F): A worker takes a smoking break in a deep shaft right off of Suthisarn Road.
