This publication is focused on the problem of domestic water supply and sewage treatment-the lifeline(basic infrastructure) in 18-20 Century Beijing, a subject rarely studied previously. Historical records on the subject are collected and reviewed and their inter-relationship is analyzed. Key contents of this study are as follows : A review is carried out on the contract documents of sale/purchase agreement for domestic water use in Beijing, records in the NIITA Collection of the Institute of Oriental Culture in the University of Tokyo. On the subject of domestic water supply in 18-20 Century Beijing, the study is conducted mainly on the waterway right system accorded to the people of Shandong, a system of human water carriers to satisfy the basic need of domestic water use in Beijing. On the subject of sewage disposal in 18 -20 Century Beijing, the discussions are based mainly on the sewage route right system, which ensured the uninterrupted and daily collection of human sewage in Beijing, and conversion of the sewage to agriculture fertilizers. This sewage disposal system helped maintain a basic and minimum hygiene standard in the city of Beijing.
