Water is a key molecule for determining the physical chemical structure of star forming regions because of its large abundance variations between warm and cold regions. As a part of the HIFI-led Key Program WISH (P.I. E. van Dishoeck), we are mapping six massive star forming region in different H2O lines with HIFI and PACS to investigate the effects of clustered star formation on feedback by protostellar outflow in such regions. Our Herschel observation are complemented by APEX CO and 13CO observations in mid- high-J transitions to study the distribution of warm gas and its physical conditions for comparison with the Herschel data. I will present large scale maps of the massive star forming region G327.3-0.6 obtained with APEX (CO isotopologues) and PACS (H2O) and report on our analysis of the region.
