Sewage Operations Threaten Graeme Hall Nature Sanctuary And Wetlands

Graeme Hall Swamp

[Bridgetown, BARBADOS] According to officials at Graeme Hall Nature Sanctuary, the emergency sewage pipe and outfall from the South Coast Sewerage Treatment Plant facility to the sea has been effectively abandoned and is not operational, threatening the biodiversity and operation of the Sanctuary and Graeme Hall wetland.

Inspections last week confirmed continued silting of the Emergency Discharge Canal Structure outfall at the bisecting canal and an inoperative sluice gate at Worthing Beach. The approved Emergency Discharge Canal Structure was completed in 2003 to direct emergency sewage to the sea when needed by the three (3) million gallon-per-day South Coast sewage facility.

In sharp conflict with the originally approved operation of the facility, during emergency operations the Barbados Water Authority (BWA) manually bypasses the Emergency Discharge Canal and pumps sewage directly into the wetland. The Sanctuary and the wetland continue to accumulate contaminated sludge from this and other source points outside the wetland.

The original design of the South Coast Sewerage Plant was based on scientific studies and design criteria established in the 1980’s and early 1990’s that sewage discharges be directed to the sea, not the wetland or its aquifer, as the Graeme Hall wetland cannot readily flush itself. Emergency sewage dumps into the wetland are also contrary to Inter-American Development Bank (IDB) operational and environmental requirements associated with the facility. The IDB financed construction of the South Coast Sewerage Treatment facility and  the Emergency Discharge Canal.

Major dumps of raw sewage at Graeme Hall have happened before.  One of the worst in recent history occurred in July 2005:  A failure of the facility caused BWA to authorize a non-standard multi-day sewage dump into the wetland instead of into the newly constructed Emergency Discharge Canal. The quantity of raw sewage was estimated to be hundreds of thousands of gallons. The 2005 dump was done without notification to general public or the Sanctuary.  As massive accumulations of raw sewage contaminated the Sanctuary, Sanctuary personnel attempted emergency cleanup operations with little success. The pollution had an immediate and long-term negative effect on Sanctuary operations:  Environmental tour and educational operations were curtailed,  and Sanctuary personnel dealt with complaints about smell, stresses to the ecosystem and its inhabitants, and unusual orange/purple colouration of the main lake.

Despite past offers of assistance from the Sanctuary, the main government-owned sluice gate drain structure in the bisecting canal has not operated for many years, preventing interactions with the sea during

favourable tide conditions.

The Graeme Hall RAMSAR wetland site is partially owned by the Sanctuary and is recognized under the 1971 RAMSAR Convention on Wetlands treaty as an internationally significant area of biodiversity.

  • I’m very much afraid that the tens of thousands of Bajans longing for a Graeme Hall National Park have given up hoping that the DLP government will disappoint their developer cronies and make an effort to save the wonderful site for the people of Barbados.


  • Yep, guess you’re right – we can kiss Graeme Hall swamp goodbye. What a disgrace. I would like to see it highlighted in the worldwide press.

    Actually, now I come to think of it, I’m surprised that over on BFP they aren’t accusing David Thompson of filtering the sewage into the swamp with his bare hands, but I guess they’re too busy congratulating themselves on their 6 millionth visitor, or something like that and digging at BU, as usual, (they’re jealous, David) with the ITAL that didn’t happen. Read cq8 = BFP =… oh heck, forget his name now, but it begins with an A, and rhymes with a northern duck. Appropriate for Graeme Hall, don’t you think?!


  • I’m so appalled at what’s happened . I still have the ‘Save Graeme Hall’ print in my rear window of the car, & get laughed at! but have also been asked by a lot of people what is going on & why has it been closed.


  • @Sundowner

    Too much politics and testosterone flewing around!


  • And we just had June as “Green Month” and Environment Minister Dr. Lowe spouting a lot of long talk about building a green economy.

    I’ve heard that Barbadians drink sea-water!! Is it true?!! Well, it could be because I’m British, but, in view of the above, it does n’t seem a very good idea!!
