The most satisfactory method of effluent disposal is controlled application to a soil/plant filter. The plant growth can use the nutrients and soil bacteria to complete the purification process. Effluent discharged into a well-sodded, level terrace is one way to accomplish this.
What is aerobic treatment?
In this process, oxygen-using bacteria attack and break down the organic portions of the sewage into simpler inorganic compounds . Aerobic treatment is preferred because it is rapid and relatively odor free.
What is package treatment?
Package treatment plants contain and process a material that is a potential health hazard. Care should be exercised in locating the plant so there is little danger of contaminating any public or private water supply.
How does a septic tank work?
Septic tank systems rely on the anaerobic (without oxygen) breakdown process that is less efficient. It produces the characteristic septic odor. Package plants maintain aerobic conditions by introducing air into the tank. This can be done in either of two ways.

Requirements
If you are about to invest in a new sewage treatment solution ( domestic sewage treatment plant, septic tank, or even packaged filter system), there are a few things you need to know about the installation. The Environment agencies across the UK created a distance calculator. County per county, here is what the legislation says:
Introduction to our Septic Tank, the Tricel Vento
Our Tricel Vento septic tank ensures sewage water treatment in a cost-effective way. It’s an affordable solution for those willing to invest into a high-quality treatment plant whilst being easy to transport from a point to another and easy to install. The treatment process happens within its two chambers.
What is an airborne hazard?
Airborne Hazards. Chemicals from wastewater treatment facilities become airborne when they're air-stripped. Air-stripping occurs when organisms, chemicals or particles in water find their way into air, where they can subsequently be inhaled.
How does air stripping affect the body?
If particles, organisms or pathogens that are air-stripped are inhaled, they go through the bronchial tubes and lungs, are cleared from the lungs, and then swallowed. This can cause respiratory and gastrointestinal exposure. Some organisms pass directly into the bloodstream. Experts at Cornell University report that though air-stripping occurs during aeration and other processes, it occurs less at wastewater treatment plants because the particles tend to attach to solids rather than water 1. The effects of inhaled organisms vary from upper respiratory irritation accompanied by eye irritation to depression, central nervous system damage and severe systemic poisoning. Plant workers are often the first affected. If they realize they've been affected, they're able to alert managers to correct the problem.
Can cockroaches be controlled?
Through proper maintenance of the facility, the spread of disease by flies, cockroaches, lice, mosquitoes, mice and rats can be controlled. Houseflies, as well as other pests such as cockroaches, can also present a health hazard for those living near wastewater treatment facilities.
Can flies be in wastewater?
Houseflies, as well as other pests such as cockroaches, can also present a health hazard for those living near wastewater treatment facilities. Flies land on the food they eat to taste it, and raw sewage attracts houseflies. The hairs on a single housefly can carry millions of pathogens, which are transferred to whatever the fly next lands on. National Small Flows Clearinghouse (funded by the U.S. Environmental Protection Agency) relates in its newsletter “Pipeline” that transferring these pathogens through flies and other pests is nowhere near as common as through drinking water or eating food that's been contaminated by sewage 2. Wastewater treatment facilities that treat and dispose of contaminants properly protect the communities surrounding them. Through proper maintenance of the facility, the spread of disease by flies, cockroaches, lice, mosquitoes, mice and rats can be controlled.
