West Sussex Septic Drains

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. 

The Geology and Drainage of West Sussex

If you are really geeky and want to get into the detail of the geology and drainage of West Sussex then this is a great read. West Sussex Minerals Local Plan.



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.

West Sussex is the western part of the historic county of Sussex, formerly a medieval kingdom. With an area of 1,991 square kilometres (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.
