Septic Tanks Mid North Coast

In the Mid North Coast region of NSW, including areas like the Port Macquarie-Hastings regions, Kempsey Shire, Nambucca Valley, MidCoast areas, Macleay Valley, and Coffs Harbour and Coffs Coast, septic tanks are essential where municipal sewer services are unavailable.

If you’re considering installing a septic tank system in these Mid North Coast regions of NSW, it’s crucial to understand local regulations and system options. Factors such as soil conditions, tank size, maintenance requirements, and local council regulations play a significant role in the design and installation process.

 

Some things to consider when installing Septic Tanks Mid North Coast include the following:
  1. Soil conditions: The type and quality of soil on your property will affect the design and installation of the septic tank system. A percolation test can be conducted to determine the soil’s ability to absorb water and to choose the required drain field size.
  2. Tank size: The size of the septic tank will depend on the size of the property, the number of occupants, and the expected water usage. A licensed professional can help determine the appropriate size for your needs.
  3. Maintenance requirements: Regular maintenance and pumping of the septic tank are required to ensure the system’s proper functioning. Following the recommended pumping schedule and hiring a licensed septic system maintenance professional to perform the maintenance is essential.
  4. Local regulations: Mid North Coast councils and LGAs (see below for links to all Mid North Coast councils) regulate septic tank system installation and use; it’s essential to check with your local council to ensure your system meets all requirements and obtains the necessary council websites:
  5. Type of system: Several types of septic tank systems are available, including traditional septic systems, which use a septic tank and drain field. Aerobic Treatment Units (ATUs) like AWTS introduce oxygen to enhance waste breakdown through to more advanced systems like Advanced STS and Advanced Membrane Bio-Reactors. Each system has advantages and disadvantages, and it is important to choose the system that best fits your needs and site conditions. If you haven’t already read our Septic Tank Buying Guide, we recommend you do so.

 

When choosing a septic tank system in the Mid North Coast, it is important to consult a licensed professional with experience in installation and maintenance in your local area. They can help you choose the right system for your needs, obtain the necessary permits, and install it properly.

Home Sewage Treatment Plant (HSTP), What Are They?

30 October 2023

Guide: Home Sewage Treatment Plant (HSTP)

A Home Sewage Treatment Plant, also known as an HSTP or Onsite Sewage Management System, is a decentralised wastewater treatment system designed for residential homes, small communities or small commercial sites that are not connected to centralised sewer systems.

The primary purpose of an HSTP is to treat and purify domestic wastewater generated in a home or small community so that it can be safely discharged into the environment without causing harm.

Regulations for HSTPs can vary by location and local council requirements, so it’s essential to know your local guidelines and standards when installing or maintaining these systems.

The HSTP receives and treats all household wastewater from the following:
  • toilet
  • bathroom
  • kitchen
  • laundry
Septic Tank, AWTS, Advanced STS Wastewater Cycle

A Home Sewage Treatment Plant (HSTP) receives all wastewater (both greywater and blackwater) from the premises, including the kitchen, toilet, shower and laundry, and quietly and efficiently recycles all your household wastewater into clean, clear and odourless water suitable for irrigation in your garden and lawns.

This Is How A Typical HSTP Works: 

  1. Wastewater Collection: The HSTP collects all wastewater generated in the home, including water from toilets, sinks, showers, and laundry.
  2. Primary Treatment: In the first stage of treatment, solid materials are separated from the liquid through sedimentation and filtration. This stage typically occurs in a septic tank, where solids settle to the bottom and are partially broken down by bacteria.
  3. Secondary Treatment: The partially treated effluent from the septic tank is further treated in aeration or treatment chambers. Here, bacteria and microorganisms break down organic matter and pathogens in the wastewater. Some systems may use alternative methods like activated sludge or aerobic treatment.
  4. Tertiary Treatment (Optional): In some cases, an additional treatment step may be required to improve the effluent quality further. This can involve processes like chlorination, UV disinfection, or constructed wetlands.
  5. Effluent Discharge: After treatment, the treated wastewater (effluent) is safely discharged into the environment. The discharge method can vary, with some systems using absorption trenches, mounds, or subsurface irrigation to disperse the treated effluent into the ground.
Garden Master Advanced Secondary Treatment System cross section AWTS

HSTPs usually comprise multiple treatment stages, including primary settling, aeration, clarification, and disinfection, treating wastewater by breaking down organic matter and reducing harmful contaminants before the treated water is discharged into the environment or dispersed via subsurface irrigation.

Home Sewage Treatment Plant Pros & Cons

Home Sewage Treatment Plants (HSTPs) offer several advantages and disadvantages, depending on your specific needs and circumstances. Here are the pros and cons of using HSTPs:

HSTP Pros:
  • Environmental Benefits:
    • Water Recycling: HSTPs treat wastewater onsite, which can be used for irrigation, reducing the demand on local water sources.
    • Reduced Pollution: Properly functioning HSTPs prevent the contamination of nearby groundwater and surface water bodies, contributing to environmental conservation.
  • Independence:
    • No Connection Costs: You don’t need to pay for connecting to a centralised sewer system, which can be expensive.
    • Location Flexibility: HSTPs are suitable for rural or remote areas where centralised systems are not feasible.
  • Cost Savings:
    • Lower Water Bills: By recycling treated wastewater for irrigation, you can reduce water consumption and save on water bills.
    • Avoid Monthly Fees: You don’t have to pay ongoing fees to a sewer utility.
  • Reliability:
    • Less Vulnerable: HSTPs are less susceptible to damage during natural disasters that might affect centralised sewer systems.
HSTP Cons:
  • Upfront Costs:
    • Installation Costs: Setting up an HSTP can be expensive, including the cost of tanks, pipes, irrigation and treatment equipment.
    • Maintenance Costs: Routine maintenance and occasional repairs can add to the long-term cost.
  • Ongoing Maintenance:
    • Regular Servicing: HSTPs require routine maintenance, including inspections, pumping, and cleaning to ensure proper function.
    • Environmental Risks: Inadequate maintenance can lead to system failures and environmental contamination.
  • Regulations and Permits:
    • Varied Regulations: Local regulations and permits can be complex, with different requirements for HSTPs depending on your location.
    • Compliance Challenges: Meeting and maintaining compliance can be a challenge.
  • Limited Capacity:
    • Sizing: The capacity of an HSTP is typically designed for a specific number of occupants and may not be easily expandable.
  • Effluent Quality:
    • Variable Quality: The quality of effluent from HSTPs can vary. Some systems might not be suitable for water reuse.
  • Odor and Noise:
    • Potential Odours: Some HSTPs can emit odours, especially if not adequately maintained.
    • Noise: Aeration systems in certain HSTPs can generate noise.
  • Energy Use:
    • Electricity Consumption: HSTPs with mechanical components, like pumps and aerators, can consume electricity.

The decision to install an HSTP should be made considering your specific location, local regulations, budget, and your commitment to regular maintenance. If properly designed, installed, and maintained, HSTPs can be environmentally friendly and cost-effective for managing wastewater in areas without access to centralised sewer systems.

Buying a HSTP

Before purchasing a Home Sewage Treatment Plant (HSTP) system, there are several important factors to consider to ensure you make the right choice for your property and needs. Here are some key considerations:

  • Regulations and Permits: Check local, state, and national regulations governing the use of HSTP systems. Ensure you have the necessary permits and approvals to install and operate such a system on your property.

We recommend reading: Septic Tank Regulations In NSW

  • Site Suitability: Assess your property to determine if it suits an HSTP. Factors like soil type, available space, and groundwater conditions can affect the system’s performance.
  • System Size: The size of the HSTP should match the wastewater generation of your household or facility. Consider the number of occupants, daily water usage, and peak flow rates when sizing the system.
  • Treatment Capacity: Evaluate the treatment capacity of the HSTP. It should be capable of treating your wastewater to meet local discharge or reuse standards.
  • Local Climate: Consider the local climate conditions. Extremely hot or cold climates may require additional insulation, heating, or cooling for the system to operate effectively.
  • Maintenance Requirements: Different HSTP systems have varying maintenance needs. Understand what is required for upkeep and whether you can manage these tasks or need professional servicing.
  • Energy Consumption: Determine the energy requirements of the system. Some HSTP systems are energy-efficient, while others may consume more power—factoring in ongoing operational costs.
  • Quality of Effluent: Assess the quality of the treated effluent. It should meet environmental standards for safe discharge or reuse, especially if you plan to use the effluent for irrigation.
  • System Brand and Model: Research reputable manufacturers and models. Choose a system with a good track record and consider factors like reliability, warranty, and availability of spare parts.
  • Local Service Providers: Ensure local professionals are available for system installation and maintenance. Prompt service is essential to keep the HSTP running smoothly.
  • Budget: Set a budget for the purchase, installation, and ongoing maintenance of the HSTP. Remember to factor in long-term operational costs.
  • Environmental Impact: Consider the environmental impact of your HSTP. The system should treat wastewater in an eco-friendly manner and prevent groundwater contamination.
  • Long-Term Plans: Think about your long-term plans for the property. If you intend to expand or make changes, consider how the HSTP will fit into your future plans.
  • Consult a Professional: It’s advisable to consult with a wastewater specialist or engineer who can assess your property and help you select the most suitable HSTP system.
  • Warranty and Support: Inquire about the manufacturer’s warranty and the availability of customer support in case of issues.
  • References: Ask for references from property owners who have installed similar HSTP systems to learn from their experiences.

Septic Tank Regulations In NSW

22 September 2023

Whether you’re a long-time septic system user or have recently had one installed, this Septic Tank Regulations guide is for you if you’re in NSW.

This article is a must-read if you’re transitioning from city to country living or considering a new septic installation in NSW. Discover how to effectively manage and operate your septic system to prevent sewage pollution, ensuring your family’s health and the environment’s quality remain uncompromised.

Firstly, septic tank regulations vary by region and are subject to change. In New South Wales, the local council or the NSW Environment Protection Authority (EPA) typically outlines septic system regulations. These regulations cover aspects such as installation, maintenance, and environmental protection. To get accurate and up-to-date information on septic tank regulations in NSW, we recommend visiting the official website of the NSW EPA or contacting your local council’s environmental health department. Alternatively, we’ve supplied and installed thousands of Septic Systems throughout NSW and can provide expert advice or point you in the right direction.

SO WHAT NSW SEPTIC TANK REGULATIONS DO YOU NEED TO KNOW?

NSW Government regulations now require registering every septic system with your council.

SepticSafe registration

Registering is necessary so councils can monitor and manage the overall impact of the septic systems in the drainage catchment. Taken
together, that is a lot of effluent, and no one wants to swim in it.

What is septic tank registration?

Registration is like registering a car. Information about your septic system is sent to the council with an application for approval. The council issues an ‘approval to operate a system of sewage management’, which sets out the basic rules you need to follow to keep the system working well.

The details are set out in the council’s on-site sewage management strategy and local approvals policy. Both of these documents are available at your council.

A fee may be charged to help the council cover the costs of monitoring and managing public health and environmental risks associated with septic systems. People in sewered areas already pay for these costs in their sewerage rates.

How does council supervision work?

council supervision for septic tank installation in nsw

Registration is like registering a car. Information about your septic system is sent to the council with an application for approval. The council issues an ‘approval to operate a system of sewage management’, which sets out the basic rules you need to follow to keep the system working well.

The details are set out in the council’s on-site sewage management strategy and local approvals policy. Both of these documents are available at your council.

A fee may be charged to help the council cover the costs of monitoring and managing public health and environmental risks associated with septic systems. People in sewered areas already pay for these costs in their sewerage rates.

 

The process works like this:

  1. Resident sends in a SepticSafe registration and pays a fee (if required).
  2. Council records the details and determines a risk classification (e.g. high, medium, low).
  3. Council issues an operating approval, which may require regular reports or site inspections.

Note that the approval relates to the owner, not the land. When the land is sold, the new owner should notify the council and obtain approval in their name.

Your septic system may be classified according to an assessment of public health and environmental risks.

Your septic system will be assessed by your council and given a risk classification for the purpose of accountability and supervision. The classification depends mainly on the area where the septic system is located.

Many councils use a three-class risk classification scheme as set out below. Sometimes, more complex classification schemes may be necessary.

HIGH-RISK AREAS

These are highly vulnerable and sensitive environments like villages and areas close to drinking water sources, oyster leases, rivers and wetlands where the release of sewage pollution can cause much harm.

Suppose your septic system is in a high-risk area. In that case, the council will arrange regular checks to assure safety and good practices.

MEDIUM-RISK AREAS

These are vulnerable areas with a lower risk of water pollution because of factors like setbacks, good soil and vegetation and lower housing density.

If your septic system is in a medium-risk area, the council may ask you to do regular checks yourself, and it may do random audits.

LOW-RISK AREAS

These are areas where septic systems are located on good soil well away from waterways, drainage lines, homes and sensitive environments.

If your septic system is in a low-risk area, registration may be all that is required, provided you ensure that it is well-managed and maintained.

As a septic system owner, you are responsible for –

  • Ensuring the house drains and tank don’t leak
  • Getting things fixed if they are not working properly
  • Keeping the system well-maintained
  • Ensuring the system is checked regularly
  • Getting the tank pumped (de-sludged) when it becomes too full to process the flow going into it
  • Maintaining and protecting the absorption field
  • You comply with the council’s requirements for installation, maintenance service and operation and paying fees for inspections or maintenance
Septic Tank Regulations In NSW

Meanwhile, the council is responsible for –

  • Providing general services for the protection of the environment, public health and safety
  • Helping people keep their septic systems working well
  • Providing a scheme of systematic management for all of the septic systems in the council area, including environmental monitoring and technical advice
  • Providing advice and contact information when people need professional services to design or maintain septic systems
  • Regulating the installation, operation and maintenance of septic systems, conducting audits and inspections and keeping a register of systems in use in the council area
  • Providing community information and education programs
  • Monitoring and reporting on the overall impact of effluent and other by-products from septic systems in the state of the environment report for the council area
  • Implementing strategies for ecologically sustainable development

How to protect groundwater

Groundwater (usually from bores) has been tapped for decades, but only recently have we started to understand how vulnerable it is to contamination from surface activities. Pesticides can find their way into groundwater, as can effluent from septic systems. Locating septic systems at a safe distance from wells, bores, creeks, lakes, and houses is vital to maintaining them well.

Badly maintained septic systems

Groundwater is easily contaminated. Make sure your septic system is located a safe distance from wells, bores, creeks, lakes and houses.

 

Failing septic systems can leak chemicals such as medicines, pesticides, paints, varnishes and thinners into the local groundwater. Some chemicals, even in small amounts, can harm the environment and public health.

Failing septic systems

Even if the septic system works well, these contaminants can enter groundwater under certain geological conditions. Fractured bedrock and shallow groundwater tables may also allow bacteria and viruses to be transported rapidly, contaminating nearby drinking water supplies.

Recommended buffer distances for septic systems

All land application systems
  • 100 metres to permanent surface waters (e.g. river, stream, lake)
  • 250 metres to domestic groundwater well or bore
  • 40 metres to other waters (e.g. farm dams, intermittent streams, drainage channels etc.)
Surface spray irrigation
  • 6 metres uphill, and 3 metres downhill of driveways and property boundaries
  • 15 metres to dwellings
  • 3 metres to paths and walkways

SEPTIC SHOPPING GUIDE

Investigate before you invest.

If you plan to purchase land for a new home, check before buying.

If a reticulated sewerage scheme is unavailable, you must consider a septic system or something similar. Your first step should be to obtain advice from your local council, local land use consultant or a wastewater expert.

If you are buying an existing home with an existing septic system, ask the seller a few important questions, such as –

  • How old is the septic system?
  • When was the tank last pumped out and de-sludged?
  • How frequently was it pumped out?
  • Have there been any signs of failure?
  • Have there been any additions to the house that might make it necessary to increase the size of the system?

Which septic system is best?

When choosing a septic system, the most important thing to consider is where it will be used, how it will be used and who will use it. For example, a septic system in a weekend holiday home will be less used than one in a large, permanently occupied family home.

The septic system you choose will depend on the site’s suitability for effluent absorption, how many people will live in the home, what area of land is available, what kind of lifestyle the family lives, and what heavy water-use appliances are in the home. A septic system specialist will advise you about what is best for your situation.

Soil type, salt content, local rainfall and the depth of the water table all need to be considered when deciding where to put a new septic system. These decisions should be discussed with an environmental specialist.

Septic systems vastly vary from traditional septic tanks, sand filters, rare evapotranspiration beds, and wetland systems to modern Aerated Wastewater Treatment Systems (AWTS) and Advanced Secondary Treatment Systems (STS), which are fast becoming the most popular choice of septic systems used throughout New South Wales, ACT and Victoria.

Remember to ask for a cost estimate for maintenance as well as installation and consider environmental impacts.

What Are Aerated Wastewater Treatment Systems (AWTS)

21 August 2023

Aerated Wastewater Treatment Systems, or AWTS, are self-contained wastewater treatment systems. 

Aerated Wastewater Treatment Systems, also known as an AWTS, is a self-contained solution for treating and processing wastewater commonly used for households or small-scale commercial properties. These septic systems employ aeration followed by clarification to biologically treat wastewater, producing a high-quality effluent.

AWTS are typically installed on properties that cannot connect to a reticulated town sewer system and have become the most popular choice for wastewater management today. The advanced treatment process ensures the final effluent is of excellent quality, reducing risks to your family’s health, neighbouring properties, and local waterways. This high-quality effluent is dispersed just below the surface of the ground, effectively reusing the treated water to irrigate gardens and lawns.

These wastewater systems are versatile and can be installed on properties with challenging conditions, such as rocky terrain, sandy soils, high-water tables, steep gradients, or limited space. Aerated Wastewater Treatment Systems are also the preferred choice in environmentally sensitive areas due to their reliability and eco-friendly design.

An AWTS receives and treats all household wastewater from the following sources:

  1. Kitchen
    • Wastewater from sinks, dishwashers, and other kitchen activities.
  2. Bathrooms
    • Water from showers, bathtubs, and bathroom sinks.
  3. Laundry
    • Wastewater from washing machines and laundry tubs.
  4. Toilets
    • Blackwater from toilets, containing human waste and toilet paper.
  5. Other Household Fixtures
    • Any additional drains or fixtures that produce wastewater within the home.

Aerated Wastewater Treatment Systems treats all this wastewater through aeration, biological processes, and clarification, producing a high-quality effluent suitable for safe disposal or reuse for irrigation purposes.

Septic Tank, AWTS, Advanced STS Wastewater Cycle

How does an Aerated Wastewater Treatment System (AWTS) work?

AWTS comprises multiple treatment stages, including primary settling, aeration, clarification, and disinfection. Aerated Wastewater Treatment Systems mainly aim to treat wastewater by breaking down organic matter and reducing harmful contaminants before the treated water is discharged into the environment or dispersed via subsurface irrigation.

Stage 1. Primary Treatment (Separation Stage)

  • Wastewater (influent) enters the primary chamber from the household source.
  • In this chamber, the wastewater separates into three layers:
    • Scum layer: Fats, oils, and grease (FOGs) float to the surface.
    • Effluent layer: Liquids settle in the middle.
    • Sludge layer: Solids settle at the bottom.
  • The primary-treated effluent flows through a transfer port into the aeration tank, while scum and sludge remain in the primary chamber.

Stage 2. Aeration (Biological Treatment Stage)

  • The aeration tank introduces oxygen into the effluent using an air blower, creating an environment for aerobic bacteria and microorganisms to break down organic matter.
  • Media within the tank supports bacteria growth and prevents short-circuiting of wastewater, ensuring thorough aeration.
  • This stage effectively digests organic waste and ensures extended biological treatment.

Stage 3. Clarification (Settlement Stage)

  • After aeration, the effluent flows into the clarification chamber, a quiescent zone where suspended particles and solids settle out of the water.
  • These particles are returned to the septic or aeration chambers via a sludge return system. This aids in further biological reduction, denitrification, and maintaining a steady microbial population for periods of limited flow.

Stage 4. Disinfection (Safety Stage)

  • Before irrigation, the effluent undergoes disinfection in a chlorinator, which removes harmful bacteria, viruses, and pathogens.
  • The automatic chlorinator administers low doses of chlorine to ensure the water is safe for reuse.

Stage 5. Irrigation (Final Stage)

  • When the final chamber reaches a set level, a float switch activates the irrigation pump, sending the treated effluent to the irrigation field.

This comprehensive treatment process ensures the wastewater is thoroughly treated, producing clean and safe effluent suitable for irrigation while maintaining system efficiency and protecting the environment.

Variations in AWTS Systems

AWTS systems come in various designs and sizes, with their capacity influenced by factors such as:

  • The number of users
  • Property size
  • Local regulations

Compliance with relevant regulatory requirements, along with proper system maintenance and monitoring, is essential for efficient operation and long-term environmental sustainability.

General Guidelines for Aerated Wastewater Treatment System Tank Sizing

Determining the ideal AWTS tank size can be challenging as every property has unique needs. However, AS/NZS 1546.1:2008 provides general guidelines:

  • A home with 4–6 bedrooms typically requires a minimum tank size of 4,500L for regular wastewater production.

It’s important to note this is a guideline only. Consulting local wastewater specialists is strongly recommended to ensure your system is appropriately sized and functioning efficiently for your specific circumstances.

Useful Reading: 

When Advanced STS is Required

Often, an Advanced STS (Sewage Treatment System) may be necessary instead of an AWTS.

By considering these factors and seeking expert advice, you can ensure your wastewater system operates effectively and sustainably.

“The treated effluent from domestic wastewater treatment systems should not be used for human consumption or to irrigate vegetables or fruit, and the irrigation area should not be used for recreational purposes

Considerations When Choosing a Septic System

We highly recommend reading our Septic Tank Buying Guide, which covers all the primary considerations. Such as:

  • Set back distances from houses, structures, waters sources etc
  •  Types of Septic Tanks and Systems
  • The average cost of a septic system
  • The process of getting a quote through to the installation
