          Strategy:            To manage the quality of surface water runoff and infiltration and prevent
                               uncontrolled discharges of low quality waters into adjacent watercourses and
                               water bodies and underlying aquifer during the construction phase.

  Water quality monitoring in hillside locations (including infiltration pits) are likely to be event based only (at least 2
per year) as it is likely that water will be absent during routine monthly monitoring periods.
