                 Editor’s Note—THE PLUMBING AND DRAINAGE ACT 2003
                 SETS OUT REQUIREMENTS FOR ON-site EFFLUENT
                 TREATMENT AND DISPOSAL. THE QUEENSLAND
                 PLUMBING AND WASTEWATER CODE AND ASSOCIATED
                 GUIDELINES ARE USED TO CONFIRM THE SUITABILITY
                 OF EACH site TO ACCOMMODATE AN ON-site SEWERAGE
                 FACILITY; OR WHERE A CENTRALLY LOCATED GROUP

                 CONFIRMATION AS TO THE SUITABILITY OF THE
                 DESIGNATED site TO ACCOMMODATE THE ON-
                 site SEWERAGE FACILITY. ADDITIONALLY, WHERE THE
                 COMBINED TOTAL PEAK DESIGN CAPACITY OF
                 EFFLUENT TREATMENT IS LESS THAN 21 EQUIVALENT
                 PERSONS, THE DESIGN OF THE SYSTEM ACHIEVES A
                 LOW TO MEDIUM RISK CLASSIFICATION IN
                 ACCORDANCE WITH SEQWATER’S LAND USE RISK
                 TOOL FOR ONSITE SEWERAGE FACILITIES.
