A maintenance agreement (also called a service contract or service plan) for your septic or AWTS system is the practical mechanism that ensures your system stays compliant, functional, and off Council’s radar. For AWTS owners in particular, a maintenance agreement is not optional, NSW regulations require quarterly servicing by an accredited service provider, and that relationship works best when it is formalised in a service agreement rather than booked ad hoc.
This guide explains what a good maintenance agreement should cover, what the differences are between agreement types, and what to watch out for when choosing a provider on the Mid North Coast.
Why a Formal Agreement Makes Sense
Property owners who rely on ad hoc bookings for septic maintenance frequently experience problems:
- Missed service cycles: Relying on memory to book the next quarterly service means the April service doesn’t get booked until June. Quarterly becomes semi-annual. Semi-annual becomes “whenever.”
- Council compliance gaps: Each missed AWTS quarterly service is a gap in the service record lodged with Port Macquarie Hastings Council. A pattern of late or missed services triggers compliance audits and notices to improve.
- Priority in busy periods: Service providers with large contract books prioritise their contracted clients. Ad hoc clients get fitted in when there is space.
- Continuity of system knowledge: A service provider who has been to your property four times a year for three years knows your system’s history, its quirks, and early warning signs. A different provider every service means starting from scratch each time.
What a Maintenance Agreement Should Cover
Service Scope and Frequency
A compliant maintenance agreement for an AWTS must specify:
- Quarterly visits (every three months): This is the minimum required under NSW Health and Council approval conditions. Any agreement offering less frequent visits is not compliant with regulatory requirements.
- What each visit includes: the service scope should be written out, not just “AWTS service.” See our AWTS guide for what a compliant quarterly service includes.
- Consumables policy: is the cost of chlorine tablets/disinfectant tablets included in the quarterly fee, or billed separately?
For conventional septic tanks without AWTS, the agreement typically covers:
- Annual inspection visits
- Coordination of pump-outs when sludge levels reach the action threshold
- Service record maintenance
Council Reporting
The agreement should specify that the service provider will lodge service reports with Port Macquarie Hastings Council on your behalf after each visit. Confirm:
- What format the reports are lodged in (electronic submission preferred)
- How quickly reports are lodged after the service (same week is reasonable; two months later is not)
- Whether you receive a copy of each report for your own records
If your service provider is not lodging reports with Council, your compliance record is not being maintained, even if the services are being conducted.
Emergency Response
A good agreement specifies what emergency response looks like:
- Response timeframe for urgent callouts (alarms, backup situations)
- Whether emergency callouts are included in the annual agreement cost or charged separately
- After-hours contact process
For holiday rental properties especially, knowing that emergency septic issues can be addressed quickly without a separate negotiation is important.
Pump-Out Coordination
The agreement should address how and when pump-outs are organised:
- For AWTS: who monitors sludge levels in the primary chamber, and at what level is a pump-out triggered?
- For conventional septic: is the pump-out included in the annual agreement, or does the agreement only cover inspection and the pump-out is billed separately?
- Are pump-out costs included in the agreement or extra?
Equipment Failures and Repairs
A service agreement is typically for servicing only, not for repair of failed components. The agreement should be clear:
- Inspections will identify components needing replacement
- Repairs (aerator replacement, pump replacement, UV lamp) are billed separately at agreed rates or market rates
- The service provider will provide quotes for repairs before proceeding
Some providers offer bundled agreements that include minor component replacements (UV lamp, chlorine tablets, small parts). These can represent good value but read the detail on what is included vs excluded.
Agreement Term and Renewal
Standard maintenance agreements run for 12 months with annual renewal. Confirm:
- Auto-renewal terms (you should have the right to terminate with reasonable notice, typically 30 days)
- Price adjustment provisions (most agreements allow an annual CPI increase)
- What happens if you sell the property mid-agreement
What Makes a Service Agreement Less Than Adequate
Watch for these warning signs when reviewing a proposed maintenance agreement:
“Quarterly service” but no defined scope: If the agreement says “quarterly service” but doesn’t specify what is done at each visit, you have no basis for holding the provider accountable.
No Council reporting commitment: If the agreement doesn’t mention lodging reports with Council, you cannot assume they will do it.
Very low price that seems too good: Sub-$100 per visit quarterly services are unlikely to be conducted properly. The travel time alone, plus the service components and consumables, means below-market pricing often means below-standard service.
No emergency contact provision: An agreement with business-hours-only availability for a system that can fail at any time is inadequate.
Automatic annual price increases exceeding CPI: CPI-linked annual adjustments are reasonable. 20% per year “due to increased costs” without notice is not.

What a Good Agreement Includes
Maintenance agreements for AWTS and conventional septic systems are offered by servicing providers across the Port Macquarie, Hastings, Camden Haven and Mid North Coast region; this site is an independent referral service, not the provider. Whoever you engage, a well-run agreement typically includes:
- Quarterly AWTS services by an accredited service provider
- Council service report lodgement after each visit
- A copy of each service report to you
- Sludge monitoring and pump-out coordination
- Clear pricing with annual CPI adjustments
Accredited providers in this region routinely cover the major AWTS brands, including Envirocycle, Biocycle and Orenco. Send an enquiry if you want help getting an agreement in place for your property.
Setting Up an Agreement When You Buy a Property
If you are buying a property with a septic or AWTS system, setting up a maintenance agreement before settlement (or within the first month of ownership) prevents a gap in service coverage from day one. We can set up an agreement for your property based on the system details before you even take possession, just provide us with the address, system type, and settlement date.
See our guide on septic system registration and change of ownership for more on what new owners need to do.
FAQ
Is a maintenance agreement legally required for AWTS owners? The maintenance agreement itself is not a legal document required by law, but the quarterly servicing by an accredited service provider IS required by your Council approval conditions. A maintenance agreement is the practical way to ensure that requirement is met systematically.
Can I have an agreement with a different provider to the original installer? Yes. You are not tied to the installer for ongoing servicing. You can engage any accredited service provider in the region to take over your service agreement. If you’re not happy with your current provider, contact us for a no-obligation comparison.
What should I do if my service provider closes or stops operating? Contact Port Macquarie Hastings Council’s environmental health team as soon as you become aware, and contact alternative providers to arrange a replacement agreement. Act quickly, even a one-cycle gap in AWTS servicing creates a compliance record issue.
Do conventional septic tanks need a maintenance agreement? Not in the same mandatory sense as AWTS. Conventional systems don’t require quarterly professional service. However, an annual check-up agreement and pump-out coordination ensures the system doesn’t get neglected. This is particularly relevant for property managers, absentee owners, and investment property owners.
Can a property manager organise the service agreement on behalf of a landlord? Yes. This is common for investment properties on septic. The property manager is the day-to-day contact, the landlord is the account holder, and service reports go to both parties. This works well for holiday rental properties.
