The Landsburg Facilities and Chlorination Project will upgrade onsite facilities to improve Drinking Water Systems core water diversion and delivery, water quality monitoring and treatment, and fish passage functions. This includes upgrading some existing facilities and consolidating others into one new facility to meet the needs of Seattle Public Utilities (SPU) and its rate payers for the next 40 years and beyond.

The Queen Anne Water System Improvements Project was a response to two issues. First, SPU completed a seismic evaluation and determined that the two previous standpipes were at a high risk of failure. Second, some Queen Anne residents were experiencing problems with their water pressure. SPU started construction in early 2007 and completed the work in the fall of 2008. Queen Anne Improvements
Seattle Public Utilities (SPU) is replacing its open reservoirs with underground structures that will improve the quality and security of our water supply and provide 76 acres of new open space. The City began installing floating covers at some reservoirs in the late 1990’s. While floating covers improve water quality, they raised concerns about security and visual impacts.
These issues led to the proposal to replace the City’s remaining uncovered reservoirs with safer, more secure underground facilities and use the remaining open space as parks. The City Council approved the plan in 2004, after SPU found the underground reservoir program would cost roughly the same as installing floating covers with improved security measures added.
