Studies conducted by Mepa show that it may not be economically viable to build artificial islands off Malta using building debris.

Replying to a parliamentary question by Labour MP Leo Brincat, the Prime Minister said that Mepa had considered the development of artificial islands or land reclamation. Two sites had been considered - Qalet Marku and Xaghajra.

The first conclusion that emerged was that since the sea was deep, the cost of building artificial islands would be high and not economically viable.

As to extensions fro the coast, 11 methods were considered. Construction costs were found to range between €15 and €40 per cubic metre.

The study also considered the use of building waste. It appeared, however, that although Malta generated a substantial amount of debris over the years, there was a need to consider if, in the long term, enough material would be available. The cost of dumping debris in quarries or in the sea was €3 and €4 per cubic metre respectively.

Dr Gonzi said that should any extension of the shore be made, the best site for further investigation would be off Xghajra.

Dr Gonzi pointed out that since the studies were completed, the economic climate had changed and new regulations had been brought in force.Therefore, the value of these results had to be considered within the context of current circumstances.
