Three foul stations at film studios

INTRODUCTION

A famous film studio complex in southeast England is undergoing an expansion. Our client, the main contractor for the project, asked us to provide three large pumping stations to accept the large volumes of foul waste which will be generated once the site is fully operational.

The site covers many acres and so long horizontal runs were a significant factor when specifying pumps.

METHOD

A dedicated project manager was assigned to oversee the project. They were specified the pumping stations based on site survey and construction drawings supplied by the contractor.

All pumping stations featured powerful and reliable DN80 three-phase vortex pumps.

Station 1 featured a 3 m x 4 m GRP chamber with DN80 ductile iron pipework. This pumping station had a horizontal run of 700 m. The control system included an ultrasonic controller and transducer head for reliability and precision with standard sewage floats providing a backup high level alarm and duty assist. These floats were set switch at a higher level than the ultrasonic system.

Stations 2 and 3 were MagnaPro chambers (2.4m x 4 m and 2.4 m x 2.5 m) with 3” galvanised steel pipework. Level control was provided by sewage floats.

Each system’s control panel was fitted with an Aqua365 Monitor for remote monitoring and to alert keyholders should a fault be detected.
Installation was staggered to fit with the overall construction scheme.

RESOLUTION

At peak times there will be many hundreds of people on site. These pumping stations will be able to cope with the waste generated.

The owner has entered an Edincare Service Agreement for planned preventative maintenance of all systems. Scheduled servicing will greatly reduce the risk of breakdown and increase the life expectancy of the equipment.

Operating and Maintenance manuals were created for handover to the end client.

FOCUS ON

Ultrasonic level controls and monitoring

Used primarily for large foul pumping stations, ultrasonic level control systems offer unparalleled levels of precision. The controller sends an ultrasonic pulse (typically 50kHz) via the transducer head then measures the time for the echo to return from the surface of the water.

They are ideal for chambers were high levels of fat and other solids may interfere with the operation of floats, or for narrow deep chambers where there is a risk of the floats being obstructed by the equipment, the chamber walls or each other.

They are also a good choice where inlet levels dictate narrow switching ranges. Floats are less precise so may not sequence correctly if the switching heights are set too close together.

The controller provides data-logging and remote monitoring capabilities.

Typically, we include backup sewage floats for high level alarm and duty assist. These are set to switch at a higher level than the ultrasonic system.
