DA parliamentary leader, Mmusi Maimane, will lead an inspection of sanitation sites in the Amathole District Municipality on Tuesday.
Algoa FM's Olwethu Xabanisa has more on this story.
The Democratic Alliance Eastern Cape Spokesperson Ntomboxolo Makoba-Somdaka says this follows a complaint filed by the DA regarding irregularities in the tender process and payments to Siyenza for toilets that were never built.
She told Algoa fm news that the party still believes that the R631 million tender to build 66 000 toilets awarded by the ADM to the politically connected Siyenza Group was irregular.
Somdaka says Maimane will be joined by DA Members of the Provincial Legislature including Athol Trollip and former Eastern Cape Premier Nosimo Balindlela.
The dignitaries will meet in King William's Town in the morning and proceed to Kwasaki Village in the Nkonkobe Municipality and Kwa-Tuba Village in the Great Kei Municipality.
