Everything you Need to Know About Maintaining an Underground Sewage Tank
All sewage tanks exist for the same reason and when designed effectively, will require occasional cleaning and maintenance to remove sludge and waste from the tank. To avoid major hygiene issues, bad odours, and potential biohazards, make sure you understand how your sewage tank works, how to clean it and how to dispose of the waste by reading our guide below.
Basics of a Sewage System
Sewage tanks are an underground structure that use biological decomposition and drainage processes to treat wastewater produced by bathrooms, kitchens, and laundries. A sewerage system is comprised of an underground watertight tank, usually made of fibreglass or concrete with two pipes connected to create an inlet and outlet. The inlet pipe is used to collect the wastewater in the sewerage tank and the outlet is used to process the wastewater from the tank.

Over time, the sewage and wastewater will separate into three layers; the top later which is oil and grease, the second layer which is wastewater particles and the bottom later which is made of heavier particles that form a solid sludge.
Cleaning the Tank
You must regularly maintain and clean the sewage tank in order to ensure it’s safe and has a long-term service life. Sewage tanks can easily overflow, so it’s important to clean the frequently depending on the purpose and size of the tank and at least one a year to prevent waterborne diseases and reduce risk of tank damage. By following a strict cleaning routine each year, you can protect the tank from clogging and breaking down. This can be a demanding, time consuming, and highly displeasing job if you lack the right equipment to perform this clean.  
Hire Professionals
When you hire professionals to clean a sewage tank, they can take care of the cleaning process and dispose of the waste to maintain a safe and disease-free surrounding. You can conduct the yearly cleaning process yourself, however having professionals’ handling the cleaning process enables the tank and waste to be treated effectively and eliminates waste matter and unpleasant odours from the tank safely and efficiently.
Removing Waste
Waste removal professionals start the cleaning process by emptying the tank and disposing of the solid waste that has been collected in the tank to prevent the drain from getting clogged. If the tank does happen to get clogged, a professional team can remove thick sludge and ensure the outlet is cleared for proper drainage. By using a professional team to regularly clean the sludge and drain the tank, you can ensure your tank is functional, doesn’t overflow and has a long-service life.
Recycling Waste
Some chemicals resulting from sewage waste collected can be recycled and converted into fertiliser for the garden and the agriculture industry. However, the heavy sludge of the wastewater, can be put into landfill when the liquid is removed as it’s not organic and cannot be recycled. Having an effective waste disposal system is an important factor during the process of cleaning and maintaining sewage tanks. A popular treatment for wastewater sludge is to recycle it as biogas and energy like electricity.
In short, it’s important for sewerage tanks to be cleaned regularly to prevent overflows and safely handle waste. Getting the right professionals to correctly dispose of the waste can ensure the tank is cleaned and drained properly, whilst being able to recycle and waste to benefit other businesses like those in the agriculture industry. When deciding on the right processionals to clean the tank, guarantee they are equipped with the right equipment and registered to treat the sewage waste and most importantly licensed to carry all types of waste.

5 Advantages of Fibreglass Reinforced Plastic Tanks

Fibreglass reinforced plastic (FRP) is a material used in the construction of chemical storage tanks and industrial process equipment. Compared to conventional chemical and liquid storage tanks, FRP combines thermosetting resins and glass fibres. 

Everything you Need to Know About Maintaining an Underground Sewage Tank

While it’s not the most glamorous topic to read about, it’s certainly an issue that can have disastrous consequences if the right measures aren’t taken to maintain an underground sewage tank.Having a sanitary, well-designed, and properly installed sewerage tank is vital to ensuring the safe disposal of waste products and contaminants to protect the health of society. 

Why Australian Manufactured Tanks are Critical

In order to meet the demands of modern workplaces, more businesses than ever are switching to fibre reinforced plastic (FRP) and composites for their chemical storage solutions. But did you know why it’s important to buy locally? In order to help our customers in manufacturing, we’ve curated a useful guide about the importance of buying local. 

Guide to Buying Chemical Storage Tanks

As chemical usage has continuously increased to meet the demands of both individuals and organisations, a chemical storage tank is now not just desirable but has become essential. A chemical storage tank is a major component within chemical and industrial storage solutions. 

Why storing chemicals correctly is important

If history has taught us anything, it’s that chemicals can have disastrous effects when they are not stored or managed properly.

How to Use Chemstore Process Tanks

Process tanks are multi-use tanks that are equipped to complete a sub-process of a larger overall process. 

The Importance of Local Manufacturing

Chemstore is a huge believer in the importance of local manufacturing. Local manufacturing is a huge benefit for the community, not only for the local economy but also for the workers in that community.  

Are Chemical Storage Tanks safe?

When it comes to storing dangerous chemicals, finding the right chemical tank solution is critical to maintaining a safe work environment. Chemical tanks are used to store fluids such as sodium hypochlorite, sodium hydroxide, aluminium sulphate, fluorosilicic acid, coagulant and ferric chloride just to name a few.


The Solution for Biogas

Chemstore was contracted by a client to build a Bio-scrubber tank for their QLD project.
