什么是On-site wastewater management
原文是这样的: Legislation impacting on recycled water use in QLD is outlined in Table 4. It is divided into two areas: on-site wastewater management systems covered by the Plumbing and Drainage Act 2002; and the second group of larger schemes covered by the Water Supply (Safety and Reliability) Act 2008.
