Situated in a natural valley, the valley floor had to
be lowered by 1m so as to reduce the overall height of
the retaining bund whilst maintaining the desired depths
of water. The water bodies were formed in the chalk down
lands and lined with a triple layer liner system, consisting
of a 400gms/m² goetextile over and underlay and 0.75mm
excelastic membrane, welded insitu.
Reed Bed Construction - Design in Association
with Watercourse Systems Ltd
Under the direction of Watercourse Systems Ltd, White
Horse Contractors constructed a vertical flow reed bed
into the chalk down lands, lined with a bentonite underlay,
0.75mm excelastic membrane and a 400gm/m² goetextile
overlay. The reed bed construction included the installation
of drainage pipeworks, headwalls, dosing chambers and
the placement of 1100 ton of Bristol Channel grit and
200 ton Oolitic limestone, both of which when combined
with the reeds acted as the filter matrix for agricultural
effluent. Commenting on the works, Dr Weedon of Watercourse
Systems Ltd states
" In undertaking installation of the vertical flow
reed bed and balancing pond, WHC were installing structures
that included details that were largely unfamiliar to
the operations. Therefore it was with some surprise
(given experience with certain other contractors) and
of great benefit to my operations that I was able to
rely on rapid uptake of my ideas and quality installation,
usually conducted in my absence in readiness for inspection.
In addition, the unusual range of plant equipment deployed
by WHC dramatically accelerated installation.
In conclusion I was most impressed with the consistent
professionalism of the WHC team, from supervisors to
ground workers, and look forward to working with the
company on future projects. " |
