  • The Various Types of Sewer Systems

    Plumber Bondi BPD_illustrationIn this article, we are going to take a look at the various types of sewer systems. This is very helpful for those who are looking for a new home since they will be able to familiarise what kind of sewage system they will be dealing with. Of course, those who just want to learn more about the nature of their current sewage system will also benefit from this article.

    Combined Sewers
    This type of sewer combines the wastes of various underground pipes like sewage, wastewater, and stormwater into one compact treatment location. Combined sewers are mostly used in urban setting, and don’t need any form of wastewater storage and pre-treatment. The wastewater in this system is not treated since it’s directly transferred to the treatment facility. Because of this issue, the sewer system is built to make sure that flow of the wastewater is continuous so that there won’t be any wastes that are stagnated in the sewer pipeline.

    To improve the flow, a downhill gradient must be structuralised. Combined sewer systems are among the safest sewer technology out there and very convenient. The problems of such sewer system are the maintenance costs, not user-friendly (which means professionals should always be hired for maintenance and repair), and needs to have frequent treatment.

    Separate Sewer
    Separate sewer is far safer than combined sewer systems since the risk of sewage overflow is very low. The fact that is has proper hygienic feature means you won’t have to worry about mosquitoes and sewer odour. It’s also convenient and has a very low chance of any health hazards. The operating costs are relatively lower than combined sewers. One of the main issues with this system is that it’s extremely difficult to set up in areas that have a high population. It’s also even more expensive than combined sewage system in terms of capital and maintenance costs.

    Simplified Sewer
    This is more of a budget sewer system since its more affordable compared to the two sewage types mentioned above. Even its operating costs are cheaper which can save you a lot of cash in the long run. It’s also easy to build and repair since the materials can be locally acquired. Extending a simplified sewer is also straightforward. Of course, it also has its own disadvantages such as: needing regular repairs and unclogging for optimal performance, must be setup by an expert, and it also needs plenty of water for the flushing process.

    Solids-free Sewer
    It’s basically the same with simplified sewer system since its cost of operation is small, easily extended and can also be constructed with local materials. What makes it viable for homeowners is that there is no problem in installing this sewage system in populated areas. It shares the same disadvantage with simplified system in terms of frequent maintenance and professional supervision for its installation. It may be inconvenient for some people since it does require the owner to be knowledgeable in doing basic maintenance and operation of the sewage system.
