铅管品制造

India - The Indus Valley civilization grows up along the banks of the Indus River in what is now Pakistan. The two most important sites uncovered so far by archeologists are Harappa and Mohenjo-Dara; both cities show considerable development including multi-level houses and city-wide plumbing.

印度——印度河流域文明沿着今天巴基斯坦境内的印度河岸而增长，两个至今仍未被考古学家掩盖的最重要地点是哈拉帕和摩诃杰—达拉，两个地方都展示出相当规模的发现，包括多级房间和全城铅管品制造。

Futhermore, at Mohenjo-Daro, a well planned city laid on a grid, with a plumbing system superior to those used in Pakistan and India today, the streets were littered with "black lumps of glass."

此外，在摩亨佐—达罗，一个在格子上的良好规划城市，拥有铅管品制造体系，先进于巴基斯坦和印度今天所使用的，街上乱丢&黑色的玻璃块煤&。
