Environmental concerns for septic tank systems

A properly maintained septic tank in an appropriate location does not necessarily pose any more of an environmental risk than the normal sewage system operated by local government, although if the sepctic tanks is not regulary maintained or is within an unstable location, then issues could arise which may cause significant risk to the immediate surroundings.

Gas and Odor emmissions:

Under the anaerobic conditions of septic tanks, sulfates especially, are reduced to hydrogen sulfide, a toxic and pungent gas, what can also be released is known as methane. Ammonia may also be present as this is what organic nitrogen compounds and nitrates can be reduced to. Carbon dioxide and/or methane may also be generated due to the fermentation processes that take place due to the anaerobic conditions.

Pollution to groundwater:

Groundwater pollution beyond acceptable limits may occur in areas with high population density. Because of this problem, some small towns have experienced how expensive it can be to build centalised water treatment systems, due to the population. Properly functioning septic tanks can be helpful for limited amounts of time, but as population density increases, it can make not much of a difference.

Pollution to surface water:

Harvest restrictions or closures can be forced upon areas where failing or improperly maintained septic systems are contributing to polution levels which may be adjacent to water bodies with fish or shellfish intended for human consumption.

It’s highly important that the location and condition of your septic tank system is taken into consideration before you e ven think about installing one, let alone discussing how to maintain it, especially if your location is of high environmental importance, which most places are as we don’t want to effect the environment on purpose.

Always ensure your septic tank system is maintained on a regular basis and if you need an professional advice or would like a quote for septic tank emptying, then visit emptyseptictank.co.uk or please give them a call today if you need help!

What is a Septic Tank?

What is a Septic Tank?

In households or business premises where there is no connection to the main sewage pipes provided by private waste treatment companies or the government, a septic system is vital and a septic tank is a key component of the overall system, which in simple terms, is a sewage treatment facility on a smaller scale.

The waste which is discharged into the tank decomposes due to the anaerobic bacterial environment that develops in the tank, which is what the term “septic” refers to. Septic tanks can also be coupled with other treatment units including aerobic systems or biofilters.

The efficiency of the septic tank is greatly reduced over time due to a build up of solids which gradually fill the tank, so it’s essential that you implement preventative maintenance on a periodic basis, so every so often, you will have an empty septic tank, which is far more efficient for waste treatment.

A vacuum truck is used to pump out the sludge, which builds up over time and should be undertaken by a septic tank professional, who has experience and knowledge of emptying septic tanks. How often this procedure is required will ultimately depend on how large the septic tank is, the input of solids and the temperature, because at higher temperatures, anaerobic digestion occurs more efficiently.

There may however, be requirements from health authorities who may want your tank emptied on intervals prescribed by them, while other people who have a septic tank installed at home or business, leave it up to an inspector, who can determine if and when the tank needs to be emptied.

Leaving the tank to overflow and leak out can have major effects on the surrounding environment, which is why it’s so important to ensure your tank is in good shape and is fixed immediately if any defects are detected. If the tank leaks out, this could also result in prosecution or fines, if you were aware or previously advised by a septic tank adviser and the recommendations are ignored.
