The Department of Infrastructure (DoI) and the Department of Environment, Food and Agriculture (DEFA) have joined forces to undertake work in Peel harbour.
The work was carried out in conjunction with the department’s sub-contractor JCK Ltd.
A spokesman for the DoI said: ‘Work is taking place to extract a quantity of river stone from an area alongside the marina boat park that had become dry.
‘This is a joint scheme involving DoI and DEFA and should be completed by the end of the week.’
The harbour was dredged in May, causing controversy after black sludge was seen being pumped into Peel bay by a newly-installed pipe which carried silt from the harbour to the end of the breakwater.
DEFA and the DoI removed 10,000 tonnes of silt.
