A contactor was due to be appointed in November last year in an attempt to end on-going sewage problems for good, with Lagoon Remediation taking place shortly after.
But in correspondence with Councillor Muir, NI Water has now admitted the work is behind schedule with the announcement of a contractor now expected to take place in May.
Councillor Andrew Muir said: “It is disappointing that NI Water has fallen behind schedule on the Kinnegar improvement works. Local residents and commuters have been living with these disgusting odours for far too long and the completion of the promised work must be an immediate priority.
“I welcome NI Water’s attempts to alleviate the sewage problem, including raising the outlet weir of the lagoons, which seems to have reduced odour complaints significantly. However these short-term solutions are not good enough and with only mask the overlying problem for so long.
Alliance activist Kate Nicholl added: “”As a Holywood resident, I’d love to be able to enjoy the town’s open spaces without the terrible smell! I look forward to the contractor being named and work getting underway later this year.”
