Why do we believe our engineers are the best?
Simply great drainage engineers, at great prices.
Septic tank configurations vary to suit the requirement. These work in conjunction with a drainage field to treat the waste water effectively and return it to the environment. Septic tanks provide an affordable, efficient and environmentally friendly way to deal with waste water.

The waste from your property flows through drains into the septic tank. This fills the tank with effluent (waste water) which is broken down by anaerobic bacteria, separating oils (which float to the top) and solids (which float to the bottom). Once this separation process has taken place, the effluent escapes through a filtered outlet towards the drainage field. In the drainage field, bacteria have a big area to thrive and the treated effluent can seep into the ground. Aerobic bacteria in the surrounding soil brings the process to a close, taking in the clean, filtered water. All that is left in the tank is the refuse.

How often does my septic tank need emptying?

Emptying and cleaning your septic tank can help prevent any overflowing or malfunctions from occurring, whilst helping maintain efficiency. How regularly you empty your septic tank or all depends on the size of the property and how frequently it is used. It’s recommended that you empty your tank every 6-12 months to maintain effective performance.

Septic tanks and cesspits

 ​What are cesspits? 

Cesspits work by providing a similar solution to septic tanks, collecting your waste and sewage. The difference between the two is that cesspit tanks do not process or treat the wastage in any way. They can fill up at a fast rate and require emptying more frequently. Cesspits are typically used when the ground is unsuitable for the waste to be treated; this can include areas in close proximity to water courses.

 How to prevent septic tank problems 

A septic tank that is not emptied on a regular basis is at risk of causing contamination to surrounding areas. A pre-planned maintenance contract is the perfect solution to minimise the risk of overflowing, blockages or costly repairs being required in the future. Routine maintenance also ensures your septic tank is compliant with legal requirements. It can also be useful to ensure no sanitary products, food waste, oils or grease enter the pipes. Using biologically friendly products is also recommended.

        ​Risks of Flooding

        Tanker services are crucial to the prevention of flooding as they assist in the removal and redistribution of excess water from areas prone to flooding. We use specialised tanker trucks equipped with powerful pumps to extract water from flooded areas, and so reduce the risk of inundation. Additionally, tanker services can transport excess water to designated storage facilities or discharge points, preventing accumulation on roads or in vulnerable areas. By efficiently removing and managing excess water, tanker services alleviate pressure on drainage systems and reduce the likelihood of flooding events. Prompt response and effective water management strategies are instrumental in safeguarding communities and infrastructure from the devastating impacts of flooding.

            Frequently Asked Questions
            How long does does a septic tank take to fill?

            This is subjective to the owner of the septic tank. The time it takes for a cesspit to fill up can vary depending on several factors such as its size, the number of occupants using the system, and their water usage habits. However, it's important to note that cesspits are not designed to be filled and are typically emptied on a regular basis to prevent overflowing.

            How much does septic tank emptying cost?

            Cesspits will vary in size - a larger cesspit will ultimately be more costly to empty than a smaller one. Generally, a 4,500 litre cesspit will range from £100 to empty, whilst an 18,000 litre will mark up at upwards of £250. Of course, total sums will differ from case to case when it comes to cesspit cleaning. 

            Is there septic tank emptying near me?

            If you live in the Kent or London area, we have local operatives in your area. We are available to carry out commercial and residential cleaning of septic tanks, depending on what you require. Give us a call and we will provide you with our next available visit date.

            Can I empty my septic tank myself?

            Due to the specialist training and equipment needed in order to empty cesspits, only experts are qualified to undertake them. Talk to us today and find out how we can save you stress and money with our experienced staff.

            Do I have to pay in advance for septic tank emptying?

            As this process can be time-dependent, we ask for payment after the job is complete.

            Will a septic tank smell?

            Kept in the proper condition, a septic tank will not cause odour to permeate outside. All waste water is contained within the tank and without any cracks or leakage, the smell will also be contained. If you smell unusual odours coming from your septic tank, give Grey-Water a call; it may be that the tank has sustained damage.

            What size septic tank do I need?

            The size of septic tank that suits your needs depends on what your needs are. For example, if you live in a house alone or with one or two other people, you may only need a small septic tank with around a 4000 litre capacity only to be emptied once every year or two. Although, if you need to accommodate a lot of people, a much larger septic tank could be necessary (perhaps in the realm of 18,000 litres).

            How do you empty a septic tank?

            Septic tank emptying can only be done with specialised equipment and proper training. A waste removal vehicle is brought in and through the use of a large pressurised vacuum attached to a hose, the sewage is sucked into the vehicle's waste tank ready for transporting to the correct disposal facility.

            Where would you find a septic tank?

            Septic tanks are found commonly in rural and urban areas where centralised sewage systems are not available. They are typically located on the property of residential homes or commercial buildings, away from water sources such as wells, lakes, or other bodies of water.
