Description
As directed by the Mayor & Council, Tucson Water is constructing a 1,4-dioxane treatment system. This system will allow Tucson Water to serve water from the TARP superfund treatment facility that meets the U.S. EPA Drinking Water Health Advisory level for 1,4-dioxane without having to blend the water with other groundwater sources.

This treatment facility will meet the drinking water regulations and will protect Water customer health.

There are two Guaranteed Maximum Price contracts (GMP). GMP1 is $4.3M, which includes chemical feed equipment and GMP2 is $10.3M and includes site work, building, piping, etc.
