Septic Tank Replacement & Installation West Sussex:

Septic Tanks are simple devices, they offer a basic level of rudimental treatment. However as with everything it has a finite life span. The main cause of a septic tank failing is some form of structural failure which means the wastewater is no longer contained within the tank and it leaks out. This means even the basic level of treatment of the wastewater does not occur and effectively raw sewage seeps out into the ground. This leads to pollution occurring and the tank sitting outside of the General Binding Rules, which are set by the Environment Agency. 

The other main cause of a Septic Tank needing to be replaced is the 2020 change to legislation concerning Septic Tanks if they discharge to surface water. Essentially as of the 1st of January 2020 if you have a Septic tank that discharges to either a ditch, river, stream, pond, or lake you will need to replace it with a Sewage Treatment Plant. Please see our more detailed article for more information: Septic Tank Rules 2020.

Septic Tank Repair West Sussex:

Can a Septic Tank be repaired? The answer to this depends on two main factors, the construction material used and the type and extent of the damage. There are two main types of construction materials, glass fibre, and brick & concrete. Modern fibre tanks are very difficult to repair if they lose structural integrity. In most cases, a replacement tank will be required. Brick & concrete tanks are easier to repair, the main factor here is the type of damage. A common situation with these types of tanks is where a wall begins to bow and crack due to the external pressure of the ground. In these situations, the tank will likely need replacing. If the leak or loss of integrity is caused by mortar having washed away then it is possible to repair the tank by repointing. 

Septic Tank Problems West Sussex:

The top 10 warning signs of Septic Tank Problems.

  • Slow flushing or in extreme cases an overflowing toilet.
  • Effluent or liquid surfacing around your septic tank, soakaway or drainage field.
  • If you’re discharging to a watercourse, a slow odorous discharge.
  • Movements in the ground in the vicinity of your system.
  • Horrible smells.
  • Gurgling or overflowing drains.
  • Septic tank problems after it rains
  • Problems with your washing machine, dishwasher, etc.
  • Your tank needs emptying more frequently.
  • Water collecting around your manholes.

If you are having problems with your Septic Tank then please head to our main Septic tank problems page: Septic Tank Problems – The signs and solutions

Soakaways West Sussex:

If you have a Septic Tank or Sewage Treatment plant then it will need to discharge the treated wastewater somewhere. There are two options either to surface water or into the ground. If you discharge to the ground and your system was installed before 2007 it was likely to a soakaway. A soakaway is simply a hole in the ground normally filled with rubble. If your soakaway fails or you are installing a new system then an old-style soakaway is no longer an allowable option. The only solution now allowable without a permit from the Environment Agency is a Drainage Field. For more information please see the following page: Soakaway Regulations.

Septic Tank & Sewage Treatment Plant  Maintenance & Servicing West Sussex.

Legally you have to have your tank serviced and emptied annually to comply with the General Binding Rules. The main reason that this is required is to ensure that your system is not working effectively and not causing pollution. We can help you here and offer a no-fuss annual servicing plan. Servicing & Maintenance page.

Septic Tank Surveys and inspections for those buying or selling a house in West Sussex. 

With the introduction of the General Binding Rules in 2015 and the 2020 ban on Septic Tanks being able to discharge directly to surface water, it has become standard practice for a survey to be required by mortgage companies and solicitors to assess any off-mains system. We offer a comprehensive investigation and report of any such system to both give you the confidence needed to buy your new property with confidence and to fulfill any legal or financing questions. If you are Buying or Selling a property with a Septic Tank, Sewage Treatment Plant or Cesspool/Cesspit then please have a look at the following links:

West Sussex towns in the area that we cover:

West Sussex is a county in the south of England, bordering East Sussex (with Brighton and Hove) to the east, Hampshire to the west and Surrey to the north, and to the south the English Channel.

The county is the western part of the historic county of Sussex, formerly a medieval kingdom. With an area of 1,991 square kilometers (769 sq mi) and a population of over 800,000.

The geology in the east of the county is dominated by Tunbridge Wells sand. The North Weald Clay which covers around a quarter of the county. In the centre there is a large band of chalk before turning back to clay, (London Clay), in the south.


Chichester in the south-west is the only city in the county and its county town. The city and its surrounding area is dominated by London Clay which lends itself to poor drainage. This can make discharging to ground problematic and costly.


Crawley is located in the north east of the county on the outskirts of London. The town and its surrounds are dominated by Tunbridge sands. While the sand offers good percolation it can be very difficult to excavate.


Worthing is located on the south coast towards the east of the county. The town is dominated by London Clay which offers very poor percolation. As in Chichester this can make discharging to ground problematic.


Horsham is just to the west of Crawley. The area is a mix of sand and clay. With sand more in the east and clay in the west.

About Homeseptic and Our Septic and Treatment Services

Homeseptic perform maintenance, repairs and installation of all makes and kinds of Septic Tanks and Sewage Treatment Plants in West Sussex. We also carry out all types of, private drainage, Soakaway and drainage field replacements for storm water, rain water and effluent.

All of us grow up in Hampshire in and around the New Forest and love the area. We have all worked in the drainage industry for the last couple of decades but have grown frustrated at the how other companies operate. This is why we formed Homeseptic. We want to do a good job at a sensible price and leave a job feeling good about the work we have done. We don’t want to over charge, we don’t want to be rushed and we don’t want to install a system we know will fail. 

Why choose us in West Sussex?

We will always endeavour to find an efficient solution to all your drainage requirements. Removing and treating foul waste from a property is crucial for safety, hygiene, your ability to sell your property in the future and to ensure you are complying with legislation. Therefore it is sensible to call in trained professionals for the installation of a treatment plant or septic tank or in fact any drainage work.

What does a waste treatment plant do?

A treatment plant processes waste to a far higher standard than a septic tank installation. It effectively combines the process of both an old Septic Tank and its drainage field. Effluence is typically clear between 96% and 98% pure water, and can be offloaded into a ditch or watercourse. From the 1st of January 2020 no Septic Tank system can be discharged directly to a ditch or watercourse. Given the challenge with soil type, the water table and access many Hampshire Properties currently discharge to a ditch or watercourse. If you are unsure give us a call and we will check your existing system.

Although standard treatment plants use gravity to operate some will require an additional pumping system. Again this is very common because of the unique challenges the geology of Hampshire provide. This is particularly the case in areas with a high water table or clay type soils. New regulation requires all owners of Septic tanks and Sewage Treatment plants to have annual services and effluent checks, this can prove crucial when coming to sell your property. Again get in contact if you have any questions.

Graf an Environmentally friendly solution

Coming from the Forest we are keen environmentalists, which is why conditions allow we offer Graf Tank products. These German engineered systems are ultra-environmentally friendly.

The Graf tanks are single chambered injection moulded systems set up to be ultra environmentally conscious from production through to output. They are also designed with no moving parts or mechanical elements making them reliable, less costly and easier to maintain. See the Graf page here.

  • Sustainability starts with the manufacturing, this type of tank tech normally requires 2.7 kWh per kg of plastic to produce, Graf have it down to between 0.38 and 0.5 kWh. Further all heat generated by the process is recovered and used to heat the companies logistics buildings. All the materials used are 100% recyclable
  • Electric usage is kept to a minimum, 46kWh per person per year for the One2Clean and 43kWh for the advanced, a 9w energy saving bulb uses 78kWh, normal sludge activated systems use 217kWh.
  • Both of the Graf systems only require one pumping process compared to three in normal systems, extending the life of the core air compressor and delivering the energy savings.
  • The unique way the system treats the waste minimises the level of sludge produced and generates market leading odourless effluent quality. Graf claim this leads to a carbon footprint of 25% compared to conventional wastewater treatment systems.

Where on your property can the treatment plant be installed?

This depends largely on the layout of the property and Building Regulations from the Environment Agency. We will assess your site and work with you to find the best solution for your installation. Ultimately a site and system which you are happywith.

West Sussex council has no advice to give, I have left a link to their site as thhis may change advice.
