Pumping and Technical Services Ltd is a specialist pump engineering company. With over 40 years of experience in the design and manufacture of chemical and refinery process pumps. PTS came to ACP with a requirement for a new pump testing tank at their new manufacturing facility in Adlington, Macclesfield. The specification was for a 12m wide x 30m long x 4m high above ground water tank c/w a removable precast concrete roof. ACP's engineer recommended the use of the new 280mm thick prestressed concrete vertical panels to form the perimeter of the tank. Including initial excavation works, from start to finish the project took a total of just 7 weeks to construct. ACP completed stage one in January, which was to design, supply and install the main tank structure.
