Dublin City Council has issued a tender document for a three-year contract aimed at keeping the streets free of chewing gum.
The last three-year contract, which recently expired, cost the local authority €1.13m, and although the next contract is expected to be secured for a significantly lower sum, the problem of discarded chewing gum is still causing headaches for city bosses.
The tender document, posted this week, shows that some streets in the city are so blighted by chewing gum that monthly cleaning will be required.
The main black-spots requiring complete removal to be carried out within a one-week period of every calendar month are as follows:
* Henry Street and Mary Street (to the junction of Jervis Street).
* O’Connell Street (from junction with the Quays to the junction with Parnell Street including both areas of central median).
* North Earl Street.
A number of other areas, including Grafton Street, Wicklow Street and Chatham Street require cleaning every two months, while other areas such as Portobello Harbour, the Civic Offices on Wood Quay and Ringsend Library will require cleaning every three months.
Other areas — such as College Green, College Street, Dame Street and Nassau Street — only contain recent deposits of chewing gum and will be cleaned every three months.
Work on removing the discarded chewing gum will have to be carried out between 8pm and 8am to reduce disruption to pedestrians.
Those seeking to win the tender have until September 9 next to apply.
The city council said it was not placing a cost on the tender, but stressed that it expected the winning tender to cost less than that of the previous three-year contract.
A spokesman for the city council said chewing gum accounts for 30% of street litter and forms the highest percentage of litter after cigarette butts, which account for 50%.
