        "description": "We emailed 4 suppliers with details of our project. There were no key themes identified.  There were no changes made to the requirement as a result and no supplier has been given an unfair advantage.\nThe information supplied was: \nThe works are:\n•\tIt is proposed to construct an attenuation basin in the green space bordering St. Dunstan's Road and Grantley Road. An existing Thames Water sewer will be diverted into the basin, which will have a 300mm permanent water level and provide an additional 440m3 of storage. A new manhole with a penstock will be installed at the sewer diversion point to ensure the sewer is fully diverted into the basin. The basin will then discharge flows at a controlled rate into the existing network on St. Dunstan's Road. The proposed basin will provide formalised storage within the park, reducing the risk of flooding by alleviating pressure on the existing network, and increasing amenity value to the area.\n•\t  \n•\tThe works associated with the construction of the attenuation basin include:\n•\t•            Excavation of attenuation basin.\n•\t•            Removal of 3 trees and relocation of existing gate. \n•\t•            New manhole connections to the existing drainage network.\n•\t•            Pipe laying.\n•\t•            Installation of a penstock valve.\n•\t•            Installation of an exceedance chamber.\n•\t•            Installation of a flow control chamber.\n•\t•            Working around live services and existing roads."
