Bloomington septic tanks are a great solution for remote or urban property owners who either cannot or do not want to be part of a municipal sewage system. A septic system is connected directly to the pipes of the residence or business and serves as an immediate filter and containment unit for water-bound domestic waste. There are certain risks related to the installation and maintenance of a septic tank; such risks have resulted in rules that need to be followed to protect the environment and property especially with the regular removal of the contents of the tank by a vacuum truck.
Depending on the size of the unit and the household, a septic tank must be emptied every three to five years. This is necessary not only because of space limitations but also because the septic tank needs to be inspected with some regularity to check for cracks, leaks and blockages. Other reasons are as follows:
Septic system pumping can also become necessary in cases of emergency. Sewage backup and drain clogging may occur due to blockages which need to be cleared immediately to keep the problem from escalating. Flooding can cause similar problems.
Emptying the primary septic container can also be a precautionary measure when there are many household members, parties with many guests, or other circumstances where many people would be using the toilets.
Sometimes septic tanks are suctioned due to permeating sewer odors escaping from the system as that could be a symptom of leaking gas needing to be repaired separately. Evidence of septic failure must be attended to immediately by a professional repair company.
It is also customary to pump out the septic system before selling property.
A septic system pumping truck with vacuum power is required to pump out the tank. Waste is suctioned from the tank using a vacuum line with a diameter of four inches or more, then transported through the line to the truck. Before the line can be connected to the truck and positioned, the hatch of the tank must be opened with the settled sludge layer and floating scum broken up to ensure waste can pass through. Once the sludge has been broken up, the pump is turned on and an operator listens to the motor to ensure it is operating correctly. Any blockage at the truck can be detected and cleared before proceeding.
If the motor is in good working order, a pump valve cover on the truck is opened and the vacuum line is attached to the valve. Small amounts of effluent matter may spill from the valve upon removal which can be easily captured by holding a bucket under the cover as it is being opened. Once the main vacuum line has been connected to the truck, the main line can be connected to any remaining sections and suctioning of the septic tank can begin. Using a high-pressure cleaner can help remove additional waste from the inside of the walls. Once the waste has been completely removed, the system can be inspected; workers should wear protective clothing and avoid inhaling any toxic fumes.
Septic tanks serve a very useful purpose for many households. As long as properly maintained by regular pumping, cleaning and inspections, they should correctly function under all conditions and for a long service life. Hopefully this information will be helpful in knowing how a septic tank is cleaned!
