The Gardens Sewage Treatment Works

WJ Groundwater undertook sewage over pumping works as part of maintenance works at The Gardens Sewage Treatment Works in Dubai.

WJ Groundwater were contracted by Hydrojet to divert incoming mains sewage from the works inlet to the neighbouring aeration tanks whilst they carried out maintenance works at the pumping station for Nakheel.

WJ installed a high performance overpumping system using two of its high capacity 400 l/s diesel suction pumps and HDPE suction and discharge lines that took sewage from the inlet chamber and distributed flows evenly between 4 no. aeration tanks. The pumps used were brand new, ultra-efficient BBA BA300k sewage pumps. They are specifically designed to handle sewage with a semi-open impeller design capable of handling solids up to 100mm. A key selling point to Hydrojet was that the pumps used nearly half the fuel consumption of those offered by other dewatering contractors which helped to reduce their costs. Further details of the pumps used can be found on technical specifications download page. Due to the sensitive nature of pumping sewage we provided 100% spare pumping capacity to ensure continuous operation, along with electromagnetic flow meters and full time supervision to monitor system performance.

The project was a great success and WJ was impressed by the professionalism of Hydrojet and look forward to working with them again on future projects.

WJ Groundwater has an extensive range of pumps and pipework and continues to expand its fleet or high capacity diesel and electric pumps. Contact us today to find out how WJ Groundwater can assist you with your overpumping and diversion works.
