We are a small and friendly company based in the  New Forest, Hampshire that specialises in Septic Tank Replacement, Surveys, Installations, Soakaway problems, 2020 regulations and Drainage Fields. Please feel free to give us a call to chat through any concerns you have or just to get a bit more information to help your understanding. Below a more detailed outline of the main services and solutions we offer.

Septic Tank Replacement & Installation Hampshire:

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 that 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 Hampshire:

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 Hampshire:

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 Hampshire:

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 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 Hampshire.

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 Hampshire. 

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:

Hampshire towns in the area that we cover:

Hampshire is the fifth largest populated county in England with an estimate of 1,819,536 people living here. It has an area of 3,791 km2. It has two cities; Portsmouth and Southampton.  In terms of districts, Hampshire comprises the following districts: Southampton, Portsmouth, Basingstoke & Dene, Eastleigh, Havant, Test Valley, Winchester, Fareham, Rushmoor, Hart and Gosport. We cover this whole area. Each has its own unique challenges for Septic Tank and Sewage treatment system installation.

Winchester on the edge of the southern downs is Hampshires capital and in fact the former capital of England. Some of the most interesting towns near Winchester include Alresford, home of Hampshire’s watercress industry and Bishop’s Waltham, with its ancient ruins. Others include Twyford, Itchen, Easton, Morestead, Hursley, Sparsholt and the various Worthy’s. Winchester has recently become a commuter town for London with many new developments and second homes springing up. Drainage is varied but we have fitted many successful septic tanks and sewage treatment plants in this area.

Test Valley

The Test Valley, with the River test flowing through it takes in the main towns of Stockbridge, Whitchurch, Andover and Romsey.  As with any river valley the drainage solutions are complex. In the valley itself it is very difficult to install a drainage field or soakaway. Thereby any Septic or sewage treatment system frequently has to discharge directly to a water course or drainage ditch. From the 1st of January 2020 it will be illegal for a Septic Tank to discharge directly to a drainage ditch or water course. You will need to replace the Septic tank with a Sewage Treatment Plant. Please get in touch and we can visit and give you a free quotation for a replacement.   

North & East Hampshire:

In East and North Hampshire you’ll find the attractive Hampshire towns and villages of Petersfield, Alton and Odiham and novelist Jane Austen’s former home at Chawton.

As draianage engineers we are particularly interested in the soil, drainage and geology of Hampshire. Here is a beginners guide.

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 Hampshire. 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 Hampshire?

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.

The Hampshire County Council offers the following advice. To be honest it’s pretty unhelpful but gives you a starting place for further research.
