Your home or business's connection to the sewer is extremely important in the overall quality of life in your home. Modern plumbing techniques have eliminated so much of the unhygienic and time-consuming practices that humans had engaged in for thousands of years. However, it is not just as simple as wanting sewer connections; you have to know exactly what type of sewer connections your building requires. Here is a short rundown of three of the most popular types so that you can make an informed choice.
The simplest and often easiest sewer connection of them all is what is known as a gravity system, or gravity sewer. It utilises the fundamental concept of gravity to dispose of unwanted sewerage through external pipes by ensuring that the destination is lower in elevation than the origin. This system requires very little maintenance originally, as there are no complicated components that can get damaged or need repairing, but it is prone to blockages later in its life cycle. Gravity systems are slowly being phased out for more responsive systems, but they are still widely available, and most plumbers can install them with little hassle.
If you have ever been on an aeroplane or a train with a toilet, then you know what a vacuum sewer system is. In essence, the system is sealed, airtight until activated by a trigger, which in this case is the flush of a toilet. Then, a special mechanical system allows the pipes to open, and the difference in pressure causes the sewerage to be sucked through to the destination. While it may seem resource-intensive, the actual running cost of a vacuum system is quite low, and it requires little maintenance because nothing can stick to the sides of the plumbing or cause cracks when it is being sucked so quickly through the system.
Similar to vacuum systems, pumping systems are a mechanical way of moving sewerage from your home to the main line. However, in this situation, the sewerage is temporarily kept in a storage well located underneath or nearby the home (preferably out of sight). At regular intervals, the pumping system will engage and move this waste on its way out of your home. These type of sewer connections are common and used for buildings where the elevation is not appropriate for gravity systems. These are fast becoming the most popular type of sewer connections and are relatively easy to maintain.
