A major drainage upgrade in Caloundra, which will help reduce flooding and protect the Pumicestone Passage, is now underway ahead of council’s Bulcock Street streetscape upgrade, due to start this month.

The upgrade includes a new underground pipeline, extending from Felicity Park on Bulcock Street, into Otranto Avenue and across The Esplanade to the Pumicestone Passage, and a custom built stormwater filter that will help prevent rubbish and sediment entering the waterways.

Acting Director Infrastructure Services Tom Jamieson said the drainage improvements were a vital part of the overall Bulcock Street streetscape and would help improve flooding in other areas of Caloundra’s CBD.

“While the drainage work has many benefits, it’s also essential for the new road design on Bulcock Street to drain properly,” Mr Jamieson said.

“The high capacity pipeline will improve Caloundra’s stormwater network and help reduce flooding in the centre of Caloundra.

“The custom-built stormwater filter, also known as a gross pollutant trap, is similar to those installed at Maroochydore last year which have proven to stop a significant amount of rubbish entering the waterways.

“This will provide invaluable protection to our internationally recognised Pumicestone Passage by improving water quality and in turn, the habitats it provides for our fauna.”

The drainage upgrade is due to be complete in late May, weather permitting, and all construction work will stop during the Queensland Easter school holidays. To further minimise inconvenience to businesses, residents and visitors, construction has been planned to take place in sections, over a series of smaller construction zones.

Construction hours will be 6am – 6pm Monday to Friday. No night works are expected.

Temporary traffic and parking changes will occur during construction. Traffic control and signage will be in place.

Council and its contractors are liaising with businesses adjacent to the drainage works to ensure owners and their customers are well-informed before and during construction.

Fast facts

  • The new drainage pipeline will be 250m long and a minimum of 750mm diameter wide, and will be installed in a minimum 2m deep trench under the road.
  • The stormwater filter (gross pollutant trap) will be 5m deep and 2m wide. It will provide treatment to a catchment area of over 5ha and will have the capacity to treat 290 litres of water per second.
  • The similar stormwater filters installed at Maroochydore in 2015 collected 10m3 of rubbish and sediment over the four months between installation and the first collection.
