Introduction

Purchasing a treatment plant is a decision that you will live with for a long time. So selecting the right treatment plant is an important first factor to consider. Once you have chosen the right plant for the site, then you must decide where to acquire it from.

You have a four main options:

The online retailers

There are many online retailers selling treatment plants. I know of a lot of them, and some know more than others about the products they are selling. If you absolutely do not want or need any assistance then this is a fine route for you and you can search for the best price online and try and get a deal.

Just keep in mind most of the people selling treatment plants online have very little real world experience and may just talk a good talk.

Builders merchant

For builders, the obvious choice if to go to their merchant. The benefit of this is credit terms, a builder will normally have a credit account and wont have to pay upfront. The downside to this is that the merchant may have very little knowledge at all about the subject. I don’t know any merchants that would point out a permit might be required for an installation, or that there might be a more effective solution to a problem. Just a word of caution

Directly from the manufacturer

You might not get the cheapest price doing this but, and certainly the opinion of the staff will be biased toward their product. But this is a route you may choose.

From a specialist installer

The specialist installer may sell you a tank, but they are often looking for an installation and normally they will only install/supply one or 2 types of treatment plant. Why is this?: because they are putting them in the ground, they want their supply chain to remain the same and they want there workers to put the tanks in fast. If a specialist installer has many different types of treatment plant on offer, their workers would get confused and have to learn each different one. From the specialist installers point of view, it’s better to just know one system.

Some installers are excellent, and if they have dedicated people in the office just for supplying people with products then this might be a good route to go down. An Example of a specialist installer who also sells products is www.owlshall.co.uk, a good choice if you are in the south east and want to but a treatment plant from someone who also offers commissioning and maintanence

Know what you want from your supplier

Knowing what you want is important, and I don’t just mean the product itself. Do you need the tank to be installed? If so find 3 specialist installers and get quotes. Do you know a groundworker that can put the tank in the ground? If so you could purchase the system online and have your groundworker install it, but do you require it to be commissioned?

Do you know that the installation you are planning on doing will meet the General Binding rules? Do you require someone to check this for you?

Checking your site meets the all of the general binding rules, writing a permit application, commissioning and looking after the treatment plant long term is beyond the help you will get from any online store.

Let’s break down what is required with each installation:

  1. Tank purchase
  2. Tank installation
  3. Tank wiring
  4. Rule adherence
  5. System setup/commissioning
  6. Regular service and support

As you can see, the tank purchase is just a small element. Buying from someone that understands the system, the rules, and can also look after it for you, is not a bad choice.

Some tips when purchasing a treatment plant:

  • Know your invert level (ie, how deep the pipes are in the ground)
  • Know if you need a gravity or pumped outlet system
  • Make sure the system you are purchasing has an alarm function (loss of pressure/blower malfunction & high level alarm
  • Make sure the system is sized correctly for the site
  • Look at where you plan to discharge the treated effluent, make this decision before looking at which treatment plant to use. Discharging to a ditch or to ground are both possible.
  • Make sure you meet all of the general binding rules for the given discharge location.
  • Notes for discharging to ground:
  • Notes for discharging to a ditch:
    • If the ditch or watercourse does not have water flowing throughout the year you are required to:
      • Apply for a permit from the EA
      • Install a seasonal drainage field, 10m in length, within 10m from the ditch
  • Make sure you have someone competent to look after the system for you.
  • Understand that "cheap" doesn't always mean "good" this is a long term investment. You're not buying a throw away item here.
