UP to 80 trucks a day will travel to and from Leslie Harrison Dam during the storage’s $24 million upgrade due to start mid-year.
Seqwater acting chief executive officer Dan Spiller said work would impact on residents but he was keen to reduce the burden as much as possible.
The organisation had already started talks with residents on potential access routes which were Dam Road, Killarney Crescent, Willowie Crescent (for small vehicles) and Howlett Road but wanted more input.
The upgrade will ensure the dam operates safely. It will last for about a year but truck movements will be limited to about nine months.
Residents could access information on the Seqwater website.
“This feedback will be considered in developing the construction traffic plans,” Mr Spiller said.
“We’ll continue to provide updates to the community as the project progresses.”
Redland City Council’s Paul Gleeson said of the choice of access, Dam Road was the only option.
The dam has been the source of considerable angst for residents.
Those who live around the storage have been annoyed that Seqwater announced in September last year not to refit the dam’s gates because it would add $18 million to refurbishment costs.
Seqwater removed the gates – fitted by Redland taxpayers in 1984 – in 2015 as part of engineering investigations and to improve safety.
It will not refit the gates because most of Redlands drinking water was sourced from North Stradbroke Island and the district also was now part of the SEQ Water Grid.
It means the dam will remain at its original level, disappointing residents who enjoyed more expansive lake views with gates fitted and the dam at a higher level.
In late 2016 the dam also was the site of an investigation after asbestos-contaminated material was dumped, earthworks were conducted on Seqwater property and habitat was cleared.
Mr Spiller said using existing dam and water treatment plant access roads was not an option, so other routes were being investigated.
Residents could view proposed routes and provide comments by visiting seqwater.mysocialpinpoint.com/leslieharrison.
Feedback must be received by February 5.
Community drop-in sessions also will be held at Redlands Indigiscapes Centre, Runnymede Rd, Capalaba on Thursday, January 25 from 5.30pm to 8.30pm and Monday, January 29 from 9am to 12pm.
