The Cornborough Range landfall has been selected as the favoured option by RWE. It is proposed that a sixty metre swath containing between six and ten 132 kVA cables will cross the foreshore at Cornborough. The preferred method of crossing this area to avoid environmental disturbance, is HDD. The landfall, sub-surface route section at Cornborough is considered feasible from a geological viewpoint. Considerable attention, however, will be required in assessing the profile of the tunnels in order to ensure the drill profile is, if possible, entirely within unweathered rock and avoiding all mapped faults and fractures, and ideally exiting offshore in soft sediments.

South West Water, Cornborough Range HDD sewage outfall. 2. Joint Nature Conservation Committee (JNCC). 3. UKHO Admiralty Charts. 4. Current and Historical (1st, 2nd and 3rd Ed.) Ordnance Survey maps. 5. British Geological Survey (BGS) Quaternary and Solid geology maps. 6. The Crown Estate renewables publications and web links. 7. References and publications relating to the regional onshore and nearshore coastal and marine geology of the region. 8. A marine survey was carried out by Land and Marine in 1991 on behalf of SWW, to inform the construction of a STW outfall pipe. Geotechnical boreholes were drilled in 1997 by Donaldson Associates, along the proposed alignment of the sewage outfall pipe. 9. Previous route selection reports generated by RPS Energy, METOC and VolkerInfra were also obtained and consulted. https://www.marinedataexchange.co.uk/details/2625/summary A link to the web service or dataset. https://www.marinedataexchange.co.uk A link to the general host site.
