What you cannot put down the drain when you are off mains
Wipes, fats and bleach cause most of the septic tank problems we attend. What genuinely harms an off-mains system, and what is perfectly fine.
Read the guideTank size, access and how far the hose has to run decide the price far more than your postcode. What a tanker visit involves and what adds to it.
A straightforward domestic empty around Chesterfield and north Derbyshire generally sits in the low hundreds. What moves the price is the volume taken away, whether the tanker can get within hose reach, and whether the tank has been left so long that the contents have set.
A tanker visit is three costs in a trench coat: getting a large vehicle to your property, pumping and carrying the waste, and disposing of it legally at a permitted site. The disposal charge is per load and it is not negotiable — it is a licensed waste stream with paperwork attached.
That structure explains most of what looks odd about drainage pricing. A half-full small tank five minutes from the depot is cheap. A large tank at the end of a quarter-mile farm track that needs two loads is not, even though it is the same job in principle.
The single biggest factor. A 2,700 litre domestic tank is one straightforward load. A 9,000 litre tank on a farm or a let is several, and each load has to be carried away and disposed of.
Tankers are heavy and they need somewhere to stand. If the vehicle can get within normal hose reach of the lids, the job is quick. If we are running extended hose across a paddock, round a cottage, or up a bank, that is more time and more hose, and on very long runs it affects what can be lifted at all. Soft ground in winter matters too — nobody wants a tanker sunk in a lawn.
A tank emptied on a sensible interval pumps out easily. A tank that has been left for a decade can have a crust you could stand on and sludge that has gone solid at the bottom. That needs breaking up and washing down before it will lift, which takes time.
If nobody knows where the tank is, somebody has to find it first. On properties that have changed hands a few times this is surprisingly common, and it is why we would rather do the first visit with a bit of time in hand.
Wipes, rag and nappies do not pump like liquid. A tank full of them is a slower, messier job, and on bad ones it is a separate conversation about whether the drainage field has been taking them too.
A proper visit should leave you with the tank emptied, the chamber lids back and secure, the area left clean, and a waste transfer note or invoice showing the waste was disposed of legally. Keep those — they are the maintenance record a buyer’s solicitor will eventually ask for, and drainage comes up in every sale now.
You should also get a verdict. Anyone emptying your tank is looking straight at it, and that is the best opportunity you will get to find out whether the baffles are intact, whether the outfall is running and whether the drainage field is coping. A firm that pumps and leaves without saying a word has given you half the value of the visit.
Prices well below everyone else usually mean one of three things: a part load (they pump what they can and leave the rest), no disposal paperwork, or a price that grows once they are on site and have found a reason. Ask what volume is included, whether disposal is covered and whether the quoted figure is the figure.
For a straight price on yours, call 07884 111 641 with your postcode and a rough idea of the tank size — or read more about what our emptying service covers. If you are unsure how often it needs doing, we have written about working out your own interval.
On a pub, a holiday park, a campsite or a farm, the conversation shifts from a one-off price to a cost per year. Those sites need emptying several times annually, often at predictable points in the season, and the sensible arrangement is a contract with a fixed schedule and an agreed rate rather than a phone call each time something smells.
The economics work in your favour there. Routed visits are cheaper per load than emergency ones, the paperwork for waste transfer is handled consistently, and the site never reaches the state where a tanker visit turns into a repair job. For anywhere that has to show an inspector a maintenance record, having one firm with the full history is worth more than the few pounds saved shopping around each time.
If you have just bought the property and nobody has ever told you anything about the drainage, treat the first empty as a survey with a tanker attached. We find the tank, lift what needs lifting, empty it, and look at the condition of the chambers, the baffles and the outfall while it is down. You come out of it knowing where everything is, what state it is in, and what interval to put in the calendar.
That is a slightly longer visit than a routine empty and worth every minute of it. Almost every expensive drainage failure we attend started with somebody not knowing what they had.
For a normal domestic tank with reasonable access, yes — tell us the postcode and roughly how big it is. For farms, lets and anything with awkward access we would rather look first than quote a number we have to change.
Not necessarily, as long as we can get to the lids and you are happy for us to proceed. Most customers on a schedule are not home.
We carry extended hose and can usually work round difficult access. There is a practical limit, and if a site is genuinely unreachable we will tell you before booking rather than turning up and charging for a wasted visit.
Out-of-hours and emergency work costs more than a planned visit, as it does with any trade. We will tell you that on the phone rather than on the invoice.
