Sewage systems are built to provide safe and effective means of disposing wastewater from households. They serve as soil-based facility that can prevent contamination in potable drinking water sources, provided that they are well-designed, properly installed, and regularly maintained.

Common Problems and Alternative Solutions for Faulty Septic Systems

Problems arise on septic systems when there are not enough spaces - something that's common in rural towns especially those situated around lakes. There is a need to modify the sewage system in these areas to allow soil treatments.

Note that drainfields (soil treatment process of septic tanks) is vital as it kills pathogens that can cause diseases to resident. This procedure can only be possible when there is at least two feet of unsaturated soil that draws the separation of the sewage system from the bedrock.

The treatment cannot be carried about when there is a risk of wastewater leak in the bedrock or penetrate the soil and contaminate the source of drinking water.

But just as said, suburban areas rarely have enough space for the soil treatment. ...
... As an alternative, communities build additional property where the treatment area can be mounded and relocated. Instead of the usual underground disposal of wastewater, the raw sewage is hauled off and stored in a holding tank.

Residents also have the option to use an in-ground trench, at-grade trench, spray irrigation system or drip, constructed wetland, or a mound. These alternatives can also effectively disperse and treat effluents in a septic tank.

In some cases, several enhancement tools are added to enhance the performance of the system or allow easier modification of the setup. These devices often come in the guise of peat or sand filters, separators of solid wastes, and aerobic septic tanks. Studies have shown their efficacy in reducing the requirements for spaces and distances of separation from the bed rock.

Importance of Addressing the Problem

Sewage systems carry what have been labelled to as black and grey water. Black wastewater contains feces, urine, tampons, toilet papers, condoms, and some other contaminants flushed down from the toilet. On the other hand, grey wastewater came from sinks, lavatories, bathrooms, washing machines and wash basins. But it is no better than black water as it contains spoiled bits of foods, oil, dirt, and detergents.

Imagining these mixing with drinking water used by households can already induce irk. But this is not a farfetched possibility as different countries face sewage system pollution that results from untreated septic systems.

The number of people being diagnosed with life-threatening cases of gastroenteritis, meningitis, salmonella infection, hepatitis, cholera, diarrhea, conjunctivitis, septicaemia, serious skin diseases and other water-borne conditions has therefore taken surge.

In worst case scenarios, lakes and other nearby bodies of water also die because of high levels of phosphate and nitrates that induce eutrophication. These bad nutrients induce rapid algal bloom that decomposes and remove dissolved oxygen contained in the water. As a result, marine lives are risked. This actually occurred in many parts of the globe including North American Great Lakes, the Guilf of Paria in Trinidad, Kingston Harbor of Jamaica and huge rivers in Eastern Europe.
