SEPTIC TANK EMPTYING
At Observe Solutions we have a fleet of tankers that can remove and dispose of all waste from septic tanks to interceptors and gullies. We have tanker vehicles that will cope with the smallest job to bigger ones which again cover both domestic and commercial customers.
Our tankers range from 1500 gallons up to 6000 with a varied range in depth.
We have fully trained confined entry crews which have state of the art equipment to access sewers and tanks.
Waste that is not decomposed by the anaerobic digestion must eventually be removed from the septic tank. Otherwise the septic tank fills up and wastewater containing undecomposed material discharges directly to the drainage field. Not only is this detrimental for the environment but, if the sludge overflows the septic tank into the leach field, it may clog the leach field piping or decrease the soil porosity itself, requiring expensive repairs.
When a septic tank is emptied, the accumulated sludge (septage, also known as fecal sludge) is pumped out of the tank by a vacuum truck. How often the septic tank must be emptied depends on the volume of the tank relative to the input of solids, the amount of indigestible solids, and the ambient temperature (because anaerobic digestion occurs more efficiently at higher temperatures), as well as usage, system characteristics and the requirements of the relevant authority. Some health authorities require tanks to be emptied at prescribed intervals, while others leave it up to the decision of an inspector. Some systems require pumping every few years or sooner, while others may be able to go 10–20 years between pumpings. An older system with an undersize tank that is being used by a large family will require much more frequent pumping than a new system used by only a few people. Anaerobic decomposition is rapidly restarted when the tank is refilled.
With regular emptying a properly designed and normally operating septic system is odor-free and, besides periodic inspection, should last for decades with minimal maintenance.
Why Septic Tank Emptying Matters
A well-maintained septic system separates solids from liquids so wastewater can be processed safely. Over time, solids build up, reducing capacity and causing odours, slow drainage or even system failure. Scheduled septic tank emptying prevents these problems and keeps your drainage performing year-round.
Common Risks Without Maintenance
- Overflowing drains and toilets
- Persistent foul odours
- Blockages and backups in pipework
- Soil and groundwater contamination
- Expensive repairs or replacements
Recommended Emptying Frequency
Most tanks need emptying every 6–12 months, depending on occupancy, usage and tank size. Commercial sites may require more frequent septic tank maintenance.
Thorough, Compliant Septic Tank Emptying
All waste is transported to licensed treatment facilities for safe, legal disposal. We supply RAMS and duty-of-care documentation as needed, and follow the correct EWC codes throughout the process. Our approach is more effective than a simple pump-out thanks to high-pressure jetting, which breaks down compacted sludge and cleans internal surfaces for better long-term performance.
Modern Vacuum Tankers for Every Tank Size
- Domestic septic tanks
- Agricultural and rural systems
- Commercial wastewater holding tanks
- Industrial sludge storage
- Cesspits and cesspools
From routine maintenance to emergency support, our fleet provides safe access and efficient waste removal in tight, rural or hard-to-reach locations.
Signs Your Septic Tank Needs Emptying
- Slow-draining sinks or toilets
- Gurgling noises in pipework
- Sewage odours near drains or manholes
- Pooling water or lush grass over the soakaway
- Backups into your property
If you notice any of these symptoms, book septic tank emptying immediately to prevent damage.
