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.
