Go to a Yahoo or Google search window and type in designing leachate collection systems. People do this every single day. It’s routine. They actually do it and click the button to search. What were they thinking when they did that? There is an almost limitless range of reasons. There are both negative and positive reasons.
Positive reasons are pleasure-seeking reasons. Gaining something you would like or increasing what you already have. The negative reasons are typically pain avoidance; looking to avoid something you don’t wish. In most things that motivate people are dominated by, either the positive aspects or the negative aspects take the lead. In this article we will be focusing on the pain-avoidance or negative side of living.
Let’s examine the three main reasons, points, mistakes or actions that any person may want to avoid here. Simply for background understanding you’ll need to know designing leachate collection systems. More specifically, you need to know how to stop them blocking, corroding, or collapsing.
So what exactly are the problems, those items we must avoid? And why would it be important to not have them? Well, when we are dealing with leachate collection systems, you will likely need to ensure that they will least for as long as the landfill.
Let’s quickly consider and analyze the 3 things you really should avoid:
First off, don’t make the pipework too narrow in diameter. This will be very important because although flows in the base of a landfill are quite low, allowance should be allowed for siltation and the build-up of organic/fungal beneath a landfill. Just how do I tell if this is sufficient? Say keep diameters to say 150mm nominal diameter at least, no matter what the flow will be ).
Next, choose an non-corrodible pipework material in leachate collection systems as far as is possible. And why is that? Leachate in leachate collection systems can be quite heavily corrosive. And how will we determine what is sufficient? Maybe choose plastic materials as pipe materials.
Finally, don’t forget that some plastics pipe materials are better than others for withstanding long periods at high temperatures. This is because many landfills have been measured with temperatures in the centre at about 45 degrees centigrade. How will you tell whether it is enough or not? Unfortunately, the oldest landfills with leachate collection systems installed to modern EU standards are no older than 30 years approximately, so how well they will be faring when 50 years old or older, let alone 100 years old, we can only predict, but not see in-situ yet.
Whenever you avoid these three items you will likely have avoided the most significant and most important negatives. This would do a lot in helping you solve, remove or avoid the potential problems. The problems that must have originally been worrying lots of individuals who typed designing leachate collection systems into an Internet search engine window.
