Phosphate & Iron Monitoring Kiosks

Design, build and commission final effluent instrumentation kiosks to measure Iron & Phopshate.


4Delivery, which is a joint venture of Veolia Water, Costain and MWH delivering services to Southern Water Services and other utilities.

Project description

The project is to design, build, install and commission final effluent instrumentation kiosks, to monitor the levels of Phosphate and Iron in the final effluent from 30 specific waste water treatment works in the Southern Water region. This project is ongoing and to date we have completed 20 kiosks with a further 10 to be completed over the next 9 months.

Our offering was based on Southern Water’s standard specifications for instrumentation kiosks and the associated services within the kiosks (power and telemetry). We then took these standard specifications and developed a proposal for two different kiosks to allow for differing facilities at site. The final design was agreed and approved by all parties and we were awarded the commercial agreement after a competitive tender process.

We receive a task order for each site and attend to survey the final effluent chamber to ensure there is capacity for the sample pumps, and agree the structure and location of the kiosk’s concrete plinth (plinth constructed by others).

The kiosk is then built to the required specification and delivered to our workshops in Wilstead where we install the services and instrumentation. The kiosks are then delivered to site and located onto the plinth at site. This location of the kiosk onto the plinth is either direct off a Hi-Ab equipped vehicle, or alternatively, when required, a suitable crane lift is organised.

Once the kiosk is located 4Delivery connect the electrical supply to the mains isolator in the kiosk and we then return and commission the instrumentation.

Note: Although the design was agreed at time of tender negotiation there have been a number of variations applied to kiosks on some of the sites, as the standard design is not always the best solution for the application. We are able to incorporate these design changes and are therefore able to make sure the final product is the best fit for the site on which it is going to be used, we do not work on the basis of “one size fits all”.

Kiosk description

There are two different kiosks applicable to this project, the only difference being the overall size, the following photographs show each of the kiosks when they have been installed at site:-
