Description

Overview
The Contracting Authority requires the design, supply and installation of tank cover systems for wastewater and water treatment assets.
As part of its AMP8 Net Zero Investment Programme, the Contracting Authority intends to deliver Cover and Treat solutions across approximately 23 sites (subject to change) to reduce process emissions by approximately 19,618 tCO₂e. Hafren Dyfrdwy also has an AMP8 regulatory commitment to deliver a Cover and Treat solution at one site, contributing a further reduction of approximately 411 tCO₂e.
The scope includes Activated Sludge Plant (ASP) lanes and Liquor Treatment Plant (LTP) tanks associated with wastewater and sludge treatment processes. These assets operate continuously and contain biologically active, aerated liquors that generate off-gases during normal operation.
Any proposed tank cover solution must be suitable for installation over live operational treatment assets and must not adversely affect process performance, operation, maintenance activities or access requirements.
The final number, size and location of sites may be subject to change and will be defined within the procurement documents.
Anticipated Scope of Contract
The successful suppliers will be required to design, manufacture, supply, deliver, install, test and commission impermeable tank cover systems for Activated Sludge Plants (ASPs) and Liquor Treatment Plants (LTPs).
The anticipated scope includes all activities necessary to provide a complete and operational tank cover solution, including design development, calculations, drawings, fabrication, quality assurance, delivery, installation, testing, commissioning, operation and maintenance documentation and warranties.
The successful suppliers will be expected to assess the suitability of existing tank structures to support the proposed cover system, including consideration of structural condition, load paths, connection methodology and access requirements. Intrusive investigations and structural remediation works are not currently anticipated to form part of the scope unless specifically instructed.
The successful suppliers will be required to work collaboratively with the Contracting Authority and its appointed designers to define interfaces between the tank cover system and any future extraction or treatment systems. The design and delivery of such extraction and treatment systems, including extraction fans, ductwork and treatment processes, is not expected to form part of this contract.
