We present an overview of our comprehensive ~600h survey with the Australia Telescope Compact Array to map the Galactic center Central Molecular Zone through spectral lines in the 21.2 to 25.6GHz range. The "Survey of Water and Ammonia in the Galactic center (SWAG)" targets ~42 spectral lines with a focus on multiple metastable and non-metastable ammonia lines as well as 22GHz water masers across the entire Central Molecular Zone at 1pc resolution. We show the morphologies of the different molecular tracers and their relation to Galactic Center objects such as the supermassive black hole Sgr A*, star forming regions Sgr B2 and Sgr C, the molecular streamers and the l=1.4 gas reservoir. A focus will be the relation between stellar water masers and their surrounding molecular envelopes.
