BOC Immingham Dissolved Acetylene Project Environmental Statement: Vol. 2 Main Text
Baseline Description
Overview
8.17 The most significant surface water feature in the vicinity of the proposed Dissolved Acetylene
Project is the Humber Estuary; approximately 1 km to the north east of the development site.
8.18 Middle Drain, which is operated by NELDB, forms the north western boundary of the development
area and discharges to the Humber Estuary. Oldfleet Drain is located approximately 900 m to the
south east of the development site and discharges into the Humber Estuary at a distance of
approximately 1.8 km to the south east of the development site. North Beck Drain is approximately
1.6 km to the north west of the development site and it discharges to the Humber Estuary
approximately 1.9 km from the proposed site. The location of Middle Drain, Oldfleet Drain and
North Beck Drain are illustrated in Figure 8.2.
8.19 Other than Middle Drain where it will be crossed by the new bridge, there are no permanent
surface water features on the site. There is a ditch along part of the northern verge of South
Marsh Road, in the Anglian Water easement area. The former route of Middle Drain, in the north
west corner of the development area, is now a depression with steep banks. Both of these
features are seasonal and regularly dry out.
8.20 There is a south east to north west running drain, which is parallel to (and on the other side of)
Hobson Way and which drains into Middle Drain. There is a ditch (standing water) which runs
along part of the southern verge of South Marsh Lane. There is a south east to north west running
drain, which is parallel to (and on the far side of) the Grimsby Light Railway and which discharges
into Middle Drain.
8.21 The fields to the south east, south and south west are drained by a series of predominantly south
east to north west running ditches which discharge into Middle Drain. The land to the north east is
drained by a series of predominantly south west to north east running ditches which discharge into
a drain that runs adjacent to and parallel to the Humber Estuary. This drain discharges into Middle
Drain. Land to the north and north west is drained by ditches which discharge predominantly into
Middle Drain.
8.22 In the wider area, the land surrounding the development site is drained by a network of field drains
which ultimately flow into the larger drains which discharge to the Humber.
8.23 The location of the smaller drains and ditches within 2 km of the development area is illustrated in
Figure 10.1 in the ecology chapter.
8.24 None of the field drains enters the proposed development area and there is no hydraulic continuity
between the development area and these drains.
8.25 There are no public foul or surface water sewers in the area.
8.26 Thus, the surface water receptors for the Dissolved Acetylene Project are Middle Drain and the
Humber Estuary and these are described in more detail in the following sections.
