Caravan parks and holiday parks in the Port Macquarie-Hastings region are a significant part of the local tourism economy. From the coastal parks at Lake Cathie, Bonny Hills, and Laurieton, to inland parks near Wauchope and the Hastings River, these facilities generate large and variable volumes of wastewater that must be managed under a complex web of NSW licensing, development consent, and environmental protection requirements.
Quick answer (BLUF)
Caravan and holiday parks in NSW require development consent that specifies wastewater management infrastructure, trade waste agreements with the sewer utility (for sewer-connected sites), NSW Health public health approval, and OSSM approval from PMHC (for unsewered sites). Grease traps for camp kitchens and kiosks, dump stations for self-contained vehicles, and regular pump-out schedules are mandatory components. Non-compliance carries serious penalties under the Protection of the Environment Operations Act 1997.
Regulatory framework for holiday parks in NSW
Caravan and holiday parks in NSW are regulated under multiple overlapping frameworks:
NSW Local Government (Caravan Parks, Camping Grounds and Moveable Dwellings) Regulation 2021: Sets requirements for facilities, including adequate toilet and shower facilities for all visitors, waste management, and site standards.
Port Macquarie-Hastings Council development consent: Park operators require development consent that specifies the approved use, capacity, and the wastewater management infrastructure required.
NSW Health Public Health Act 2010: Holiday parks are public health premises and operators must comply with NSW Health’s guidelines, including requirements for wastewater management facilities.
NSW EPA POEO Act: Any discharge of wastewater from the park to a waterway or land without authority is an offence. Park operators must ensure their wastewater management system prevents overflows and contamination.
PMHC OSSM (for unsewered parks): Parks not connected to reticulated sewer require OSSM approval for all wastewater streams, sewage from toilet/shower blocks, kitchen greywater and blackwater, and any grey water from site facilities.
Wastewater streams in a holiday park
Caravan and holiday parks generate several distinct wastewater streams that must each be managed:
Amenities block (toilets and showers): The primary sewage stream. High peak loading at morning and evening routines, particularly during holiday periods. On-site systems must be designed for peak occupancy with adequate buffer capacity.
Camp kitchen and kiosks: Commercial kitchen operations require grease traps. Even a basic camp kitchen with a gas barbecue and wash-up sink generates enough grease loading to require a grease interceptor under PMHC trade waste or OSSM requirements.
Laundry facilities: Laundry wastewater is greywater, detergents, lint, and hot water. On sewer-connected parks, this goes directly to the sewer. On OSSM parks, it must be managed as greywater.
Dump stations: A dump station allows self-contained vehicles (caravans, motorhomes) to empty their black and grey water tanks on-site. This is a mandatory facility on modern parks and a significant wastewater volume during peak season. Dump stations must connect to the sewer or OSSM system, not to any stormwater or natural drainage.
Boat wash areas: Coastal parks may have boat wash facilities. These generate wastewater containing salt, lubricants, and biofouling materials that should not discharge to stormwater.
OSSM design for unsewered caravan parks
An unsewered caravan park requires an OSSM system designed for commercial-scale wastewater treatment.
Capacity design: The system must be sized for maximum site occupancy. For a 100-site park with an average of 3 persons per site at peak, that’s 300+ person-equivalents generating approximately 60,000+ litres per day of wastewater. This requires commercial-scale treatment, typically a package treatment plant, community AWTS, or septic system with multiple large tanks and an extensive absorption or irrigation area.
Treatment standard: PMHC and the NSW EPA may require treatment to a higher standard than residential OSSM, typically secondary (Class 2) or tertiary treatment, before dispersal.
Grease management: Camp kitchens require grease traps appropriately sized for commercial kitchen use. Grease trap waste disposal requires a licensed liquid waste contractor and waste manifest documentation.
Dump station management: Dump station waste must be received into a system capable of handling concentrated black water. Many parks require a dedicated holding tank for dump station waste that is periodically pumped out by a liquid waste contractor rather than routing dump station waste directly into the main OSSM system.
Pump-out schedules: setting up for compliance
A park that doubles its occupancy during school holidays may double its daily wastewater load for 4-6 weeks per year.
Proactive pump-out scheduling: Arrange pump-outs at predictable intervals before each peak season. Parks with large holding tanks may operate on monthly pump-out contracts during peak season, reducing to quarterly in off-peak.
Emergency response plan: Peak season pump-out emergencies can occur. Have an emergency pump-out contractor arrangement in place before the peak, not during it.
Dump station pump-outs: Dump station waste volumes spike sharply during long weekends and holiday periods. Separate tracking of dump station volume helps forecast when pump-out is needed.
Licence conditions and record-keeping
Parks with EPA pollution licences have specific record-keeping requirements including:
- Monthly wastewater volume monitoring
- Maintenance records for treatment systems
- Overflow incident reporting (any overflow must be reported to EPA within specified timeframes)
FAQs
Do caravan parks need a separate approval for a dump station?
Yes. A dump station is a wastewater receiving facility and requires PMHC development consent and, for unsewered parks, OSSM approval for its connection to the wastewater management system. Adding a dump station to an existing park that doesn’t have one requires a development application.
What are the penalties for a caravan park sewage overflow in NSW?
Significant. A sewage overflow from a licensed premises that causes or threatens material environmental harm is a Tier 1 offence under the POEO Act, with penalties up to $5 million for corporations and $1 million for individuals. Even lower-tier offences carry penalties of $250,000+ for corporations. Environment Protection Infringement Notices can be up to $15,000.
How often should a caravan park’s main septic/OSSM system be pumped?
For a medium-to-large park operating at moderate occupancy, monthly pump-outs of primary settling tanks are common during the operating season. Smaller parks with very large tank capacity may manage with quarterly pump-outs in off-peak periods. Your system designer and PMHC approval conditions should specify the minimum frequency.
Can I install a constructed wetland system to manage caravan park wastewater?
Constructed wetlands can be used as a final treatment and dispersal step after primary and secondary treatment. They require PMHC OSSM approval, a qualified design, and ongoing management. They’re land-intensive and require a suitable site with flat topography, adequate area, and appropriate setbacks.
