Foundation Article: RECORD BREAKING SLUDGE STORAGE TANKS INSTALLED IN UK

The Black & Veatch project at the Knostrop WwTW has the twin objectives
of proving an advanced sludge processing facility together with a new
odour control system for the new and existing equipment. As part of the
project a number of new holding tanks are being constructed. The tanks
themselves consist of a reinforced concrete base design and built by
Black & Veatch, with an innovative pre‑cast post‑tensioned concrete
segmental wall designed, supplied and installed by A‑Consult. The
pre‑cast nature of the walls has enabled the tanks to be erected in a
remarkably short time, thus ensuring that there has been a minimum of
disruption to other construction activities.

At 12 metres high, the tanks themselves are the tallest structures of
their type erected in Europe and consist of a series of Pre‑stressed and
traditionally reinforced
concrete panels held together with internal post tensioning cables. The tanks
each have 67 cables, again the largest number for such an installation.
The tanks were installed using an innovative lifting and stay technique
developed for the site, which has very tight size constraints and
overhead high voltage cables adjacent to it, further complicating the
procedure. The final element of the completed structures is the access
stairways and covers, which were provided by Kirk Engineering.

Overall the integrated approach by the Black & Veatch / A‑Consult teams
have enabled the erection of some record breaking tanks in record
breaking time with no safety, cost or programme impediments, truly an
example of Building a World of Difference."

Thickener Building Polymer Room

For the thickener building, the floor of the polymer room has been poured and the underground pipework placed.

21 Day Panel Erection

A Consult have lifted the tank walls into place for tank 5 and started tensioning the tendons.
