Consulting services for water-supply and waste consultancy

Tender description

The scope of work is to cover water resources hydrological and hydrogeological investigations into the impact of abstraction upon groundwater body status (excluding water quality) and surface water body hydrological regime, and the related options appraisals. Work may also include investigations into water dependent terrestrial ecosystems. The main scope of work is the completion of water resources investigations and options appraisals between 1.4.2020 and 31.3.2022, as per Anglian Water’s Water Industry National Environment Programme (WINEP). Outputs must meet the official Environment Agency PR19 driver guidance. Currently, eight schemes have a regulatory obligation date of the 31.3.2022, whilst the River Brett scheme which has a regulatory obligation date of the 31.3.2021. The current programme includes nine schemes, which will include both an investigation and an options appraisal element (unless the outcome of the investigation is that there is no requirement for an options appraisal). Investigations will include reviewing the impact of abstraction upon groundwater and/or surface water bodies. In some cases, this will include existing river support schemes which will also need to form part of the review. It is likely that the Environment Agency regional groundwater models will need to be utilised as part of the investigations. The options appraisal must review all available solutions, such as habitat restoration, source closure, abstraction reductions, abstraction relocations, license trading, flow support, and catchment solutions. Awareness of potential strategic options (identified separately to this scope through the Water Resources Management Plan) will also be required. Full costs for selected options must be provided in a format suitable for input into AWS business planning (format to be confirmed after appointment). This work will involve significant liaison with the client, and with the Environment Agency. Liaison with other stakeholders such as Natural England may also be required (HD and SSSI drivers). The River Brett scheme is a partnership scheme and will require liaison with Affinity Water and Northumbrian Water (Essex and Suffolk Water). The Ardleigh scheme is also a partnership scheme and will require liaison with Northumbrian Water (Essex and Suffolk Water). Final solutions must have full agreement from the Environment Agency and any other key stakeholders.
