Not everywhere can be on mains drainage and in these cases, a sewage treatment plant is essential. There are many different sizes available and are suitable for homes right up to large facilities involving large numbers of people, including factories, schools and hospitals. The installation of these units is best left to experts because the lie of the land and the requirements of the user have to be taken into account for the installation to be a success. MPC services offer an invaluable after-sales regular maintenance plan which makes sure that the unit gives many years of trouble free service.
Why choose sewage treatment?
A sewage treatment plant is not ‘storage’ which needs periodic emptying, but a unit which actually converts biological waste into a harmless product that can be safely discharged into the environment. This is achieved through biological, physical or chemical means and is largely a personal choice – for those who are keen on environmental considerations, the former is often the first port of call, but all result in the same end product and there is no real difference in installation. It is essential to have experts to examine the ground around the proposed installation, to make sure that the drainage is adequate and most local authorities also need to pass the project to comply with environmental needs. Biological units come pre-seeded with the required enzymes and are operational in 24 hours – most solids are converted to liquid waste, and emptying is usually only necessary every five years or so, depending on size.
Installing a small unit
Assuming that all the necessary elements are in place, such as a watercourse nearby to take the clean effluent or a suitably well-drained site, and that all environmental needs are met, a small unit for an average family does not take long to fit. Some people upgrade to a sewage treatment unit from a smaller one or a septic tank, so pipework is already in place. Installing from scratch will normally mean that pipes have to be laid as well, but this can all be done when the hole is being dug for the actual treatment plant. These vary in size from a small family to 120 people or more. Some are very easy to install, being add-on units to existing septic tanks (as long as an outflow is already in place) in in this case, little digging is required.
Leaving access in an attractive way
Although sewage treatment plants don’t need constant attention, they do need periodic emptying and maintenance so they need to be accessible. Many people manage this by putting them under a flowerbed with inspection covers concealed between visits by maintenance staff by plants or even a planter. Others need to have their plants placed under drives and there are special designs which are suitable for that. Some people are concerned about having a sewage treatment plant installed in seasonal buildings, such as holiday homes, but the bacteria can stay alive for periods exceeding six months, so there is no need for worry on that score. Essentially, a sewage treatment plant is very low maintenance and as such is ideal for anyone who is not always around to look after it and who wants to install it and forget it.
Things to remember
When deciding to install a sewage treatment plant you will have to bear in mind a few things, not only the logistics of digging a very big hole! You will first of all need to clear the idea with your local council, who will check that there will be no discharge of untreated sewage. They will also make sure that there will be adequate access for maintenance reasons which will not be annoying to neighbours. You will need to make sure that any exhaust pipe is downwind of you and everyone else in the vicinity – although a sewage treatment plant is largely clean in use, there may be smells even so, so try not to fall into the trap of thinking that because it is underground you won’t know it’s there; sometimes, you will! If you choose a motorised unit, you may get noise as well, but with everything taken into account, a sewage treatment system is still one of the best options for many and will give good service for years, with very little worry for the user.
