Everything you need to know about Septic Tanks

Septic tank

What are septic tanks?

Many buildings and homes have on-site wastewater management systems-often referred to as septic tanks- their purpose is to treat sewage at the location, as oppose to transporting the waste through a treatment plant or more complex sewage system. They are popular in rural areas but are often found in urban areas also; commonly use to treat sewage from an individual building.

It is imperative to know whether your building is on a septic system, as septic tanks are buried and can be easily forgotten, which can result in sewage backing up into the building, or surfacing near the septic tank.

How does a septic tank work?

  1. Untreated sewage from a building flows into the septic tank where the solids are separated from the liquid.
  2. The solid material material is then separated based on their density. Heavier particles will settle at the bottom, whilst lighter particles will form a layer at the top of the tank.
  3. Biological processes are then used to help degrade the solid materials
  4. Finally, the liquid flows out of the tank into a land drainage system and the remaining solids are filtered out

Septic Tank- Domestic Building

How would you notice a failed septic tank?

A septic system failure causes untreated sewage to be released, which can result in sewage or wastewater coming to the surface of the ground above or around the tank, or to the drain field. In worst case scenario waste will be backing up into the pipes located in the building.

The Signs:

  • Water and sewage from drains, sinks and toilets backing up into the building
  • Settled water or damp spots near the septic tank or drain field
  • Foul odors coming from the septic tank or drain field
  • Bright green, spongy textured grass over the septic tank/ drain field, even during dry weather
  • Gurgling sounds in the plumbing system
  • In domestic buildings bathtubs and showers drain very slow

Sewage carries pathogens and various other unsafe contaminants.Exposure to such contaminants can cause health issues for individuals. Contaminants may also be found in water sources, making it unsafe for drinking, swimming, shellfish harvesting and agricultural uses.

What are the reasons a septic tank might fail?

1.Piping from the building connected to the tank is blocked

When this occurs, drains drain very slowly (this may be more apparent on lower levels of the building) or in extreme cases drains may stop working completely. Clogged piping can be prevented by only flushing human waste and toilet paper and by having your system inspected annually.

2. Inlet baffle to tank is blocked

This failure is very similar to when the inlet pipe from the building to the tank is clogged.

Again, this can easily be avoided by only flushing human waste and toilet paper into the system. In the case of attempting to unclog the pipe extra care must be taken to not damage any septic system components, which is why a professional should always be contacted in the case of failure.

3. Effluent filter / outlet baffle is blocked

This type of failure usually results in sewage backing up into the building or even surfacing near the tank. This can also symbolise that the tank is receiving too much water in short periods of time. If the system contains an effluent filter, in the case of failure it is to be cleaned or replaced; if there is not an effluent filter in the system the tank will need be pumped to allow inspected and remove the clog.

4. Drain field has failed 

When a drain field fails- or is saturated with water- sewage may back up into the building. Soggy, wet areas will be noticeable above the drain field as well as bright, green spongy grass above the tank area. This may mean that the system was operated incorrectly and as a result excessive amounts of solid material made it to the drain field causing it to fail prematurely. Or the system may have failed due to existing for many years and having no more capacity to accept waste. This can be rectified by drying out the drain field and rehabilitating it. The best thing to do is to contact a professional to asses the situation and identify the required actions.

How to prevent failure 

Routine maintenance carried out by a professional will ensure proper operation and longevity of your septic system. If you are looking to install a new septic system it is also imperative to contact a professional to ensure the system has been designed, sited and installed correctly.

Septic systems and pumps should be serviced and inspected on an annual basis.

You can prevent failure of the system by avoiding excess water use, and monitoring what is put down drains and flushed into the system.

AVOIDING non-biodegradable items.

Cougar Pumps have fully equipped and qualified engineers who can inspect and asses systems to ensure you’re getting the reliability you deserve.

We also offer service contacts which provide routine maintenance.

The Pump Spotlight

Choosing the correct pump is no easy task, non-specialists may often be overwhelmed by industry terminology and the endless options in market.

There are many factors to take into account such as:

  • What fluid will the pump be dealing with?

This is one of the most important factors when selecting a pump, by identifying what pump is appropriate for handling the fluid at question, corrosion and unnecessary wear and tear on your pump can be avoided. What’s the consistency? Is it a slurry (thick suspension of solids in liquids), or is it a clear fluid?

  • Flow rate

To accurately select a pump, it is imperative that you know the flow rate. Measured in gallons per minute (GPM), although this may be translated into the pump diameter measurement. A higher flow rate, means a larger pump size is needed.

  • Viscosity

The viscosity of the fluid is also an important factor to take into account, high viscosity fluids require most robust pumping equipment.

  • Temperature

How hot will the fluid being pumped be? The temperature of the fluid will affect which pump materials are best suited for the application.

  • Pressure

Taking into account the pressure conditions on the inlet and outlet of the pump will also help determine what pump materials are best suited for the application.

Sourcing all of this information and comparing it with product offerings from many manufacturers may seem a very daunting task & 9/10 times it is best to speak to a specialist even if it is just for reassurance. However, it is still useful to be aware of different product ranges and what applications different pumps are suited for.


That is why we’re excited to reveal that we’ve teamed up with our Industry Partner, Grundfos to grant you with the ‘Pump Spotlight’ designed to give you a deeper insight into different pumps from the Grundfos product range.

  •  Find out which pumps from the product range are best suited to your desired application.
  • Determine the features of the vast Grundfos pump product range.

We will be bringing you one pump in the ‘spotlight’ every Friday, so keep an eye on the Cougar Pumps blog.



Mechanical Seals

Mechanical seals are used to prevent liquid from leaking out of pumps, between the rotating shaft and the pump casing.

Earlier pump models may use mechanical packing (otherwise known as Gland Packing).

If you’re wondering why your mechanical seals keep failing, then this blog post can assist you in advising 5 possible reasons as to why this may be occurring and how to overcome the issue of failing mechanical seals.

1.The pump has been ‘run dry

Not only does this have an impact on mechanical seals, but this can affect other areas of the pump such as the impeller. Running pumps dry can cause the impeller to melt along the shaft, causing the impeller to seize onto the shaft.

2. Heat caused the o-rings to deteriorate

3. The seal materials were attacked by the fluid being sealed

4. There is an operator error

Skipping initial start-up procedures are a big factor when it comes to mechanical seal failure. Improperly starting the pump can cause the motor to trip and the shaft to twist causing undesirable orbit movement.

5. The wrong seal has been installed or the seal has been installed incorrectly

So now you know what might be causing Mechanical Seal failure, but what can you do to avoid failure?

1. Choose the correct seal

Lack of knowledge and information will only cause obstacles in the seal selection process. Before deciding on a seal, you should carefully consider the application and operating conditions. It is highly likely that you may need to speak to a specialist to ensure the information yo have obtained is accurate, or even to obtain the information required.

2. Properly install the seal

Mechanical seal installations should be performed using the specific steps outlined by the manufacturer, taking care to avoid damage to the seal faces and / or O-rings.

Seeking assistance from a specialist to do this is also likely to be necessary.

3. Prevent excess heat generation

Excessive heat generation between seal faces can drastically reduce seal life. Dry running should be avoided at all costs. Dry running typically occurs when a pump is flooded or the seal chamber is incorrectly vented before pump start-up.

4. Maintain proper storage conditions

Mechanical seals are composed of many unique parts and a variety of materials. Because of the diverse properties and precise nature of these components, it is imperative to understand how long a seal can be stored safely without compromising function.
