River Murray and Lower Lakes catchment risk assessment for water quality: Results and management options Management option 14 Establish a planning strategy and guideline for marinas and houseboats on the River Murray in South Australia that addresses the issue of vessel moorings and sets a framework for development assessment. Illegal moorings should be assessed and removed if necessary. 236 Status of implementation: Planning SA coordinating consultation and developing draft strategy Non-commercial houseboat construction is also unregulated in South Australia. Most other forms of development in the River Murray corridor are regulated in some way. Standards and/or control over houseboat/residential vessel construction could help address potential risks before vessels are launched. Management option 15 Relevant agencies (eg Planning SA, councils, EPA, DWLBC, DTEI) and groups (eg BIASA, Houseboat Hirers Association) to investigate the concept of an approval process and standards for houseboat construction. Status of implementation: Not started Vessel wastewater discharges were also identified as a moderate pathogen risk to raw water supply environmental values in some locations. The risk is considered to be greatest for unfiltered supplies. There was some uncertainty as to the magnitude of this problem. Management option 16 The DTEI, SA Water, councils and EPA discuss the issue of houseboat mooring areas identified in the risk assessment as being in close proximity to raw water off-takes. Possible zoning regulations should be considered. Status of implementation: Not started Uncertainties in the risk assessment: Some water quality and quantity data for greywater discharges from vessels was available but this was not comprehensive. Marinas Risk level: moderate Possible options: capital works, capacity building, compliance, and policy/planning Suggested lead stakeholders: EPA, DTEI, BIASA, Houseboat Hirers Association, marina and vessel owners Marinas were identified as a moderate risk to water quality due to potential wastewater discharges, fuel spills and in some cases slipway wash off. Few marinas identified in the study (eg Hindmarsh Island) were
River Murray and Lower Lakes catchment risk assessment for water quality: Results and management options EPA licensed but several were noted to be over the 50-vessel threshold for licensing. Resources have been allocated within the EPA to address the licensing of such operators. Management option 17 The Code of Practice for Vessel and Facility Management: Marine and Inland Waters is implemented and enforced on the River Murray and Lower Lakes, including auditing (and licensing where applicable) of marinas and other multiple vessel moorings Status of implementation: Not started, awaiting finalisation Uncertainties in the risk assessment: Water quality data from most marinas was not obtained. River vessel waste disposal stations Risk level: moderate Possible options: capital works, capacity building, compliance, policy/planning Suggested lead stakeholders: DWLBC, EPA, DTEI, BIASA, Houseboat Hirers Association Vessel wastewater disposal stations were assessed as a moderate risk to water quality (through accidental spillage of blackwater). The number of vessel wastewater disposal stations on the river is clearly inadequate and large distances separate some stations (eg 96 km between Mannum and Swan Reach). It is unreasonable to expect boat owners to travel such large distances and this, coupled with the current inadequate enforcement checks, leads to an increased risk of wastewater discharge into the river or onto its banks in some locations. Management option 18 Further river vessel wastewater disposal stations should be installed, in particular the proposed Walker Flat station, a station at Wellington and additional shore-based (portable toilet) facilities on the Lower Lakes. Status of implementation: Planning started for Walker Flat station (subject to funding availability) with DWLBC coordinating Wastewater infrastructure (STEDS pumps and wastewater lagoons) Typical risk level: typically low–moderate, high for Mannum and Murray Bridge WWTP lagoons and Waikerie STEDS lagoons Possible options: capital works, policy/planning, research, review of SOPs Suggested lead stakeholders: EPA, Department of Health, SAMDB NRMB, local councils Several wastewater lagoons (eg at Waikerie and Paringa) and STEDS pumps are located in close proximity to the river and posed a risk through leakage to groundwater (lagoons with no lining or leaking lining) and/or failure of infrastructure (pumps, pipework failure, lagoon overflow). 237
