High Quality Sewer Construction. After completing a new sewer pipeline to convert toilets in the Barkor and Shasarzur and Tengyeling areas, the THF workers give their guarantee that the sewer pipeline will not leak. Good quality sewer construction not only lasts longer, but also helps keep the piped water supply clean and the groundwater supply safe.

The contents need to be emptied manually and were used as fertilizer until the old night-soil collection system broke down more than a decade ago. Fields were no longer within reasonable distance of the city center, and the crowded space within a building leaves little room to attempt composting on the spot.
