Vacuum Sewerage can Reduce Construction Costs

DUBAI - The use of Vacuum Sewerage over traditional gravity collection systems, especially on reclaimed or manmade islands, proves to be far more cost effective in the Middle East, say experts.

“Water desalination in the Middle East accounts for approximately 75 per cent of the world’s total capacity, which is a great opportunity for the regional power generation requirement. The opportunity to reuse wastewater makes both environmental and economic sense,” Mohanned Awad, Director Business development, Corodex Industries said.

He was addressing the two-day Waste Management Conference in Dubai recently.

The conference specifically addressed the challenges and opportunities in Construction, Wastewater and Solid Waste, and Oil and Gas sectors. Many case studies were discussed during the first day of the conference for Waste Recovery in Cement Kilns, Municipal Solid Waste management in Dubai and cost reducing initiatives towards construction and development through the incorporation of efficient technologies.

“Bearing in mind the immense environmental impact the region poses by having one of the world’s largest carbon footprints, it is vital for us to have eco-compatibility as a prime consideration,” he added.

In addition to the cost cuts, he stressed on the environmental compatibility of the vacuum sewerage technology to collect domestic wastewater from the urban dwellings through the presentation of their already implemented model at Dubai’s Palm Jumeirah project.

Recent developments within Gulf countries has resulted in a great demand for environmental and life style friendly technologies. In the vacuum sewerage system, the sewer pipelines are kept in vacuum and the sewage is transferred by pressure difference. With this peculiar transfer principle, the sewer construction cost is saved and the water conservation is much more as opposed to conventional gravity based systems.

The vacuum sewerage system is especially suitable for manmade islands and reclaimed land.

Vacuum Sewerage systems are wastewater collection systems in which an air stream generated by differential air pressure drives the wastewater towards a vacuum station.

A vacuum sewer system consists of: 1. a vacuum Station, where the vacuum is generated, the wastewater is collected, and then pumped to a wastewater treatment facility. 2.

A vacuum pipeline system, typically consisting of a branched network of vacuum sewer pipe, and collection chambers with pumps and interface valve units.
