Pump hire specialist, Sykes Pumps has helped to enable vital maintenance works, ensuring that the Environment Agency can control water levels on the Upper Medway Navigation.

The project at Allington Lock in Maidstone, Kent, involved an upgrade to the wheel assemblies on one of the gates on Allington Sluice. Specialist contractor, Hunton Engineering, was responsible for converting the sluice gates' wheel assembly from water-lubrication to a grease-based system and upgrading some of the components to ensure robust operation of the sluice gate and extend its service life.

While much of the engineering work was done in a workshop off site and the wheel assembly removal and installation carried out at high level, over pumping of the water between the stop locks located either side of the sluice gate was required to enable scaffolding to be erected for the project.

Sykes Pumps provided a Super Wispaset 150 capable of pumping 90 litres of water per second with a noise level of just 65 dBA at 7 metres. The fuel-efficient, compact unit over pumped water from between the stop locks, transferring it downstream into the tidal section of the River Medway while the scaffolding was erected to create a safe working environment for the Hunton Engineering team.

Once the scaffolding was in place, the pump was taken off site and the water was allowed to rise to normal levels while the Hunton Engineering team carried out the works. At the end of the project, Sykes Pumps brought the pump back to site and re-commissioned it so that the water could be safely over pumped once more while the scaffolding was disassembled.

Comments engineering director at Hunton Engineering, Sean Trow: "We had used Sykes Pumps on other schemes so we knew that we could trust the company to provide us with the appropriate kit, commission it correctly and work flexibly with us to ensure that the pump was operational when we needed it and removed from site when we didn't.

"Routine maintenance schemes like this one are a vital part of managing our waterways and, thanks to this scheme, the sluice gate at Allington Lock is ready to give many more years of efficient service."
