Sampling chamber

Home » Water Treatment » Sampling Chamber

Sampling chambers are inspection chambers installed at the outlet of a treatment plant, a separator or any discharge point to collect representative samples of the water and enable the monitoring and control of the effluent. Good sampling is essential to check the treatment performance and compliance with the discharge limits.

At Inza we manufacture them in rotationally moulded polyethylene, prefabricated and with full top access, with inlet and outlet connections in DN110 or DN160 depending on the installation. They are light, corrosion-resistant and easy to install.

Delivery time: to be confirmed, depending on the size and component stock.

Transport included in the price, excluding the unloading means at destination; for capacities over 5,000 L, please ask.

Your sampling chamber questions answered

What is a sampling chamber and what is it for?

It is an inspection chamber installed at the outlet of the treatment to collect representative samples of the water and control the effluent quality before its discharge. It is usually a requirement of the discharge authorisation for the monitoring and control of the treatment performance.

How is a sample taken correctly?

The chamber must have inlet and outlet at different heights to collect the flowing water and not the stagnant one; it is best to place the outlet at the bottom. The sample is taken in clean containers and, where regulations require it, by means of representative, integrated sampling at different periods of time. It is then analysed in a laboratory.

Is a sampling chamber compulsory?

In most installations with a discharge authorisation, yes: the river basin authority requires an accessible point for the monitoring and control of the effluent. The specific conditions are set by your discharge authorisation and by municipal and regional regulations.

What models and connections do you offer?

We manufacture the chamber in rotationally moulded polyethylene, with full top access, in two inlet/outlet connections: DN110 and DN160 (references IARQ110 and IARQ160). Choose the one that matches the pipe of your installation.

Where is it installed?

At the outlet of the treatment unit (treatment plant, grease or hydrocarbon separator, septic tank…), at an accessible point for sampling and inspection. It is installed buried, on a levelled base, with the cover accessible at the surface.

What material is it made of and does it require maintenance?

It is made of rotationally moulded polyethylene, corrosion-resistant and with a long service life. Maintenance is minimal: keep the chamber clean and accessible so that the samples are representative.

Does it come with accessories?

As an option, a reinforced cover and a neck extension (riser) to adapt the level to the installation depth. Ask us for your case.

How sampling chambers work

The sampling chamber is installed at the outlet of the treatment (treatment plant, grease or hydrocarbon separator, septic tank…) and acts as an accessible point where the already treated water flows before its discharge:

Inlet and outlet at different heights: so that the sample corresponds to the flowing water and not to the water stagnant inside. It is recommended to place the outlet at the bottom of the chamber.
Full top access: allows the container to be introduced and the sample to be taken comfortably, as well as registering and inspecting the pipework.
Taking the sample: in clean containers; where regulations require it, by means of representative, integrated sampling at different periods of time.
Analysis: the sample is taken to a laboratory to check the discharge parameters (BOD₅, COD, suspended solids, etc.).

In-house manufacturing and technical advice to choose the model and the accessories (reinforced cover, neck riser).

Why choose Inza sampling chambers?

Choosing Inza sampling chambers means ensuring reliable discharge control with a simple, durable unit. We manufacture them in rotationally moulded polyethylene, with full top access and DN110 or DN160 connections, and we advise you on the most suitable model and accessories for your installation.

Important notice: installing a sampling chamber for the monitoring and control of the discharge is usually a requirement of the discharge authorisation. The information on this page is indicative; consult your town council, the regional authority and the relevant river basin authority for the conditions applicable to your case.
