How frequently does it need to be serviced?

Usually sewage treatment plants are designed keeping in mind the ease of users. And thus, in most cases, they are user-friendly and need minimal maintenance. However, it is always good to get the plant checked professionally by a service engineer at least once in every year. It is also needed to de-sludge the plant yearly so the solid buildup doesn’t hamper the functionality of the treatment chamber. A complete empty and care plan may be adopted to maintain the plant.

How much do you need to spend towards servicing a sewage treatment plant?

Service and maintenance requirements in terms of sewage treatment plants differ between sizes and models. The basic service and maintenance contracts usually include requirements such as periodic checks, de-sludging as well as needed repairs from time to time. So it depends on the make and model as well as size of your plant that how much it would cost to service it. However, it won’t cost you an arm and a leg.

What are the things included in a sewage treatment plant service contract?

Usually, there are a number of things that are taken care of during servicing of the plant. And some of them are as follows;

  • Air filter check as well as replacement, if needed
  • Checking strength and efficiency of air blower
  • Quality of final water check
  • Checking mechanical components and replacement, if needed
  • Checking air pipes
  • Checking diffuser
  • Checking bacteria health

There are many more that are also taken care of apart from the above ones during servicing the plant.

Nevertheless, servicing must be done by a qualified and experienced engineer. They must be accredited to a reputed governing body. Besides, they should have right training and inoculations to avoid various sewage-related ailments. Servicing a sewage treatment plant is not something that can be done following a DIY guide. It should be handled professionally.

Does the plant need being emptied?

Yes, the key job of such a treatment plant is to clean wastewater. Sludge, i.e., the solid buildup inside the plant (like septic tank) has to be washed and removed on a periodical basis. Any leading sewage treatment plant manufacturer suggests yearly emptying of the plant. However, lower budget plants may need to be emptied more frequently.

Can rainwater enter the plant?

Rainwater or surface water shouldn’t enter the plant. Such plants are specifically designed to treat wastewater. With large and random flow of water into the plant, the system may,

  • Flush out essential bacteria
  • Flood the entire system
  • Dilute wastewater and thus make the whole treatment ineffective

So, surface water and rainwater drainage must be kept separated from the wastewater drainage.

These are few important things that you should know regarding proper maintenance of a sewage treatment plant.
