When new sewer work is getting done, one of the biggest things they do is to replace the pipes. That's because there are a lot of old pipes out there which are falling apart and when a sewer pipe falls apart, it can cause all kinds of problems, including various illnesses. There are a lot of things that the pipes can be made out of. One of the newer materials is high density polyethylene.
High Density Polyethylene
HDPE is a kind of plastic. It's used in a lot of different places, including in the water bottle that you drink out of. There are a lot of reasons that it has become the popular choice when it comes to water and wastewater lines. Small polyethylene pellets, called PE pellets, can be melted down and using an injection molding process can be turned into just about anything, including sewer pipes
Strength and Durability
One of the reasons that you find in places like sewer pipes is that it has a relatively high strength to density ratio. That means that it is really strong for how dense it is. That will allow it to stand up to things that may cause other sewer pipes to crack. That strength also makes the pipes very durable. They are able to stand up to the weather as well as to insects and rodents, as well as any kind of rot or corrosion.
Liners and Boots
Another reason that HDPE has become popular with plumbers is that it's possible to just slide liners into existing pipes. The outside of the liners will mate up to the inside of the existent pipe and help to seal up and cracks and such. It can also prolong the life of the sewer line, which can allow for more urgent work to be done first. There are also HPDE liner boots which can be used with already existing sewer pipes and such. These boots are able to slip over any openings or junctures where pipes might meet or a liner may be penetrated. The boots are designed to help keep that area from leaking, which can be good for the surrounding area and will keep the raw sewage going to where it can be treated instead of leaking out where it can cause a biohazard.
Making sure that the sewer lines are as up-to-date as possible and in as good as shape as possible is important. There are a lot of problems that broken down sewer lines can cause. HPDE pipes and liners can help make the sewers safer.
