	Southern Water operates two groundwater abstractions near to the Lukely Brook, which supply a large proportion of the Isle of Wight with clean drinking water. Southern Water has had a number of environmental regulatory undertakings as part of its AMP6 NEP (National Environment Programme) and AMP7 WINEP (Water Industry National Environment Programme), which aim to ensure that groundwater abstractions are environmentally sustainable in the long-term, and seeks to mitigate any quantified impacts resulting from water company abstraction on watercourses and the valuable ecological habitats they support.

	Under the AMP6 NEP and AMP7 WINEP, Southern Water have undertaken a programme of ecological and hydro-geomorphological improvement works on the Lukely Brook between 2020 and 2024 to improve the ecological resilience of this chalk winterbourne stream and adjacent ecologically designated floodplain meadows. The environmental enhancement works include the removal of a weir, installation of three fish passes, two ‘Stage Zero’ floodplain reconnection schemes, realignment and reprofiling of a historically modified section of channel, and removal of a weir along with reprofiling of banks in a town centre public amenity space. The final element completed in 2024 was restoration of the river channel though a disused highways ford next to Southern Waters water supply works in Carisbrooke. Successful delivery of the scheme has been achieved through partnership working with the Island Rivers/Newport Rivers Group and continued positive engagement and consultation with landowners and other local stakeholders.

	Monitoring took place at the various schemes at a variety of spatial scales and frequencies. Under the AMP6 impact assessment investigation and HMWB WINEP implementation project a monitoring network was established from 2017 comprising groundwater and surface water levels, flow, water quality, fish and macroinvertebrates. This monitoring was continued, and additional monitoring was undertaken on the schemes delivered in the AMP7 WINEP which added to longer term monitoring established previously. A summary of the monitoring is detailed below (note that following completion of the AMP7 WINEP, this monitoring programme is being continued at a reduced frequency to 2030).
