Did you know that there are about 287 wastewater treatment plants in Australia? Yes, this number will grow eventually as population numbers keep getting fatter with time. Wastewater treatment plants fulfil an impressive number of water requirements within the country, and more than 85% of the population has access to wastewater treatment plants at the present time. This is why the main infrastructure in these treatment plants has to be in top condition. The basin is among the key infrastructures of the plant, where its maintenance is quite challenging for several reasons.
In this article, we will discover the main challenges that are associated with wastewater basin maintenance and ultimately let us walk you through the best solutions.
Key Challenges of Wastewater Basin Maintenance
Ageing Infrastructure
This is one of the major challenges in wastewater basin maintenance because, with time, the huge infrastructure tends to age and therefore might collapse, posing threats to the whole plant. How is this possible? Is it not well-built? Just like any other infrastructure, the materials used in the construction of wastewater plants can degrade, leading to cracks, leaks, and structural weaknesses.
These issues can compromise the integrity of the basin. The obvious result is costly repairs and potential environmental barriers.
If the truth is spoken, the plant authorities could identify these potencies in advance, which is true luck. Because when you can spot them, you will be able to take the necessary precautions. If not, the authorities will have to wait until the infrastructure shows some critical signs of collapse.
Maintenance tasks are made more difficult by a shortage of replacement parts for outdated equipment, demanding inventive fixes, and even unique manufacturing.
Corrosion and Deterioration
The hidden areas of the basins, such as underground pipes or submerged structures, are often inaccessible or require specialised inspection equipment, which is actually tough to solve. It is challenging to identify corrosion or deterioration until significant damage has occurred.
Even if the issues are fixed, they may have already progressed to the point of causing leaks, structural failures, or environmental contamination. On the other hand, accessing these areas for repair or maintenance can be time-consuming, costly, and complicated to process.
It is true that these issues need to be solved immediately. However, addressing corrosion and deterioration in hard-to-find basin areas demands innovative inspection techniques, such as remote monitoring or robotic inspection tools.
Sediment Buildup
First, let us explain how this occurs. Over time, sediment accumulates at the bottom of basins, reducing their capacity and impeding the flow of wastewater. This buildup can lead to increased turbidity, decreased hydraulic performance, and decreased treatment efficiency.
It is not easy to find solutions for this challenge. Removing sediment requires specialised equipment and procedures because, first, it requires draining the basin, and then it is only possible to clean it.
However, this process can be time-consuming and labour-intensive. There is no need to say that it is costly, disrupts normal operations, and requires downtime.
Odour Control
Wastewater basins contain organic matter undergoing decomposition, which releases very unpleasant compounds like hydrogen sulphide and ammonia. These odours not only cause discomfort to nearby residents and workers but also pose environmental and public health concerns.
You may know that implementing effective odour control measures requires careful consideration of various factors, such as the type and concentration of odour-causing compounds, airflow patterns, and local regulations.
Finding the optimal balance between different odour control techniques, such as chemical additives, biological treatments, or physical barriers, can be complex and will require ongoing adjustments. This is only possible with robust technology in today’s world.
Water Level Monitoring
This is another highly challenging aspect when it comes to wastewater basin maintenance, as it is critical for preventing overflows or underflows.
On the one hand, accurate water level data is essential for optimising treatment processes. They are required to manage flow rates and detect potential issues such as blockages or equipment malfunctions. However, when fluctuating flow rates, debris accumulation, and variations in basin geometry happen, this task becomes double challenging.
The wastewater authorities cannot handle this issue just by utilising traditional monitoring methods, such as float switches or ultrasonic sensors, as they may be prone to inaccuracies or malfunctions. This is especially true in harsh or corrosive environments.
Sludge Management
Wastewater plants produce a large volume of sludge. But why is it so challenging? That is because of the unlimited volume of sludge produced and its complex composition, it requires an environmentally responsible disposal, which is quite tough. However, the good thing about wastewater sludge is that if it is managed well, you could produce environmentally healthy products like biogas and natural fertiliser for agricultural purposes.
Handling and disposing of sludge requires careful planning and adherence to strict regulatory guidelines to prevent environmental pollution and public health risks.
Plus, sludge can be challenging to dewater, transport, and treat due to its high moisture content and potentially hazardous components, where the authorities need robust tools.
Adherence to Regulations
This is a top challenge in wastewater basin maintenance due to the complexity and stringency of regulatory standards for water quality, environmental protection, and public health in Australia.
Did you know that all wastewater treatment facilities must comply with a myriad of local, state, and federal regulations? Not only that, but the plants also have to undergo frequent updates and revisions. The authorities have to spend a large force of labour and time on ongoing monitoring, data reporting, and the implementation of specific treatment processes and operational practices.
The worst part of this is that non-compliance with regulations can result in fines, penalties, reputational damage, etc. This cannot be reversed if it occurs. This is why wastewater plants need to employ modern technology for operations.
Energy Consumption Issues
Wastewater treatment facilities are all about energy-intensive operations! This means they require a large volume of electricity for pumping, aeration, and other essential processes.
High energy consumption not only contributes to operational expenses but also increases the facility’s carbon footprint and environmental impact, which is quite challenging for the environmental regulatory compliance factor.
The main challenge is that excessive energy usage can lead to overheating of equipment and infrastructure. This might expedite wear and tear on them and lead to collapses or downtime.
This is where you need to understand that balancing the need for energy-efficient operations with maintaining optimal treatment performance requires the implementation of energy-saving technologies and practices.
Changes in Climate
You know that Australia is experiencing shifts in rainfall patterns, increasing the frequency and intensity of droughts and floods. Yes, this is a country with uncertain climates.
These changes strain water resources and affect wastewater treatment processes, leading to fluctuations in the quality and quantity of water.
Furthermore, rising temperatures and more frequent heat waves enhance overheating problems in treatment plants, jeopardising the resiliency of equipment and energy efficiency.
Also, extreme weather conditions such as hurricanes and cyclones can harm infrastructure. This will result in treatment operations being interrupted, and the likelihood of pollution will increase.
