The Chichester Ship Canal is a leisure waterway linking historic Chichester to the sea. The canal runs 4 miles from the Basin to the Harbour at Birdham and, today, the 2 miles as far as Donnington is navigable.
It is valued by local residents and holidaymakers who enjoy the many activities – narrow boat trips, rowing, canoeing, rambling, fishing, and cycling. Management of the activities and maintenance of the canal is the responsibility of Chichester Ship Canal Trust, who lease the canal from West Sussex County Council.
The Canal Trust is a registered charity with c 450 members, whose aims are the preservation, maintenance and improvement of the navigation between Chichester and the harbour – a historical monument to the transport revolution in Britain in the 19th century. The Trust is entirely manned by around 140 volunteers who crew the boats, run the shop, bailiff the angling and carry out maintenance and restoration work.
Part of the maintenance and cleaning of the Chichester Canal involves the disposal of green waste with the use of heavy machinery. The design and construction of a revetment at the site used for the disposal of green waste was carried out by Cain Bio-Engineering in 2017. The project was part of a set of maintenance works done by Cain for the Chischester Canal. Key in the new design, was the strength to support heavy machinery used in the process of green waste disposal, for which a triple-tier revetment was installed in the canalbank.
The works involved the removal of a previous, failing structure which allowing the mooring of a single barge, and the installation of an improved revetment with mooring sufficient for two barges at a time.
The new structure was constructed in three tiers to provide the strength necessary to support the weight of heavy machinery. The lower tier was made of 6ft posts installed along the bank line at 400mm above water level; the second tier of 10ft posts placed with top-height at bank-line level and the third tier was constructed using 8ft posts placed 300mm behind second row for back wiring.
Cain Bio-Engineering installed a triple-tier revetment long enough to provide mooring for two barges and able to support the weight of heavy machinery used in the process of green waste disposal.
