A procurement expert says the investigations into the procurement of over 12 000 metric tonnes of expired chemicals are inconclusive. Collins Agyeman Sarpong insists further investigations are needed to thoroughly tackle the gaps in procurement. It has been established in an investigative report from the committee tasked by the Water Resources Minister Collins Dauda that 0.7 percent of the expired chemicals was used for water treatment at the Weija Treatment Plant. Agyeman Sarpong explains the report’s observation on how the chemicals were procured and cleared from the port with lots of documents missing should be a source of worry to the BNI. Speaking on Multi TV’s AM Show the procurement expert demanded clarity from the management of the GWCL and the Ghana Urban Water Limited. “Now we need to go into it. When did the procurement officer receive the document from the supply? “How many weeks, months does it take to get the original documents from the supplier? Agyemang Sarpong says there are lot more questions than answers on the issue. Meanwhile Communications Director of the CPP, Nii Armah Akomfrah has called for heads to roll at the Ghana Water Company. He believes the expired chemical scandal shows a bigger problem of mismanagement and corruption at the Water Company and called for a serious shake up.
