Processing unit No.1 recommissioned at BSTP

The first step in returning the Bridgetown Sewage Treatment Plant (BSTP) to optimum capacity has been completed with the recommissioning of one of two processing units there.

Processing Unit No.1, also known as the contact tank was out of operation for two years; added with additional sewage diverted from the South Coast Sewage Treatment Plant (SCSTP) the plant was on the verge of collapse.

On assuming office Prime Minister Mia Amor Mottley elevated the south coast sewage challenge to a national crisis, established a cabinet sub-committee chaired by Minister of Energy and Water Resources the Hon. Wilfred Abrahams and tasked it with oversight of the crisis.

Earlier this month, Minister Abrahams launched a $400 000 emergency fix at the plant which included cleaning and repairing both processing units and cleaning the wet wells at the River Road Lift Station and the BSTP.

Private contractors Project Recycle/Jose & Jose, teams from the BWA, the Ministry of Environment and the Sanitation Service Authority (SSA) worked together and around the clock to meet the deadline set by the minister. It also took five skip trucks, two cranes, two bobcats, a hazmat team of eight, two paramedics on a 24-hour, shift rotation and a team of Health and Safety Officers to get the job done.

Rains over the last week delayed completion of the first phase of the project which saw focused activity including the removal of debris, bush and plants from Processing Unit No.1; the repair and re-installation of the 35-foot, three-ton bridge which usually sits over the unit; the cleaning, repair and replacement of pipes and diffusers, the clearing of valves and the repair of the 12-inch airline.

An estimated total of 758 m3 of sludge was removed from PU#1 and disposed in a specially created spot at the Mangrove Landfill, equipped with open trenches to accept the waste which was spread and covered in layers using substances like fly-ash, organic substance and white lime.

Now back in operation the unit carries about a million gallons of wastewater which will be treated and disposed of as effluent.

Work on Processing Unit No.2 is expected to start shortly. (PR)
