Accumulation and releasing of trace metal elements on aluminum containing sediments of inner drinking water pipe is discussed, as studied from five variations effecting: raw water quality, chemical reagents, solution pH and drinking water flow condition . In order to decrease the release of trace metal elements, and to ensure the pipe operation and human safety, water quality adjustment is suggested to avoid aluminum containing sediments formation in drinking distribution system. The maximum amounts of accumulation of common trace metal elements are given. Future trends of development in this field are also proposed.
