IT WILL be one of the biggest engineering projects in Havant for decades.
A pipeline is set to be built from Brockhampton in the south to Havant Thicket in the north and will carry millions of gallons of water every year.
It is essential for the proposed reservoir at Havant Thicket to go ahead.
The pipe will connect the reservoir to the Havant and Bedhampton springs, from where most of the area’s water is sourced.
Following a public consultation, Portsmouth Water has come up with a proposed route for the pipeline. It’s based on a route chosen by more than three-quarters of those who responded to the consultation.
The route will pass mainly through open space along the Hermitage Stream and Riders Lane stream.
Any disruption will be years away, however, as work is not likely to start until 2030.
The route has to be devised now as Havant Borough Council is in the process of allocating land for houses.
Some of land must be set aside and not developed so the pipe can be built.
The reservoir, aimed at alleviating water shortages, is set to be completed by 2035.
Managing director of Portsmouth Water Neville Smith said: ‘Securing a pipeline route from the springs to the proposed reservoir site is crucial to the delivery of the Havant Thicket winter storage reservoir.
‘We have taken on board feedback from local residents and identified a route which wherever possible avoids main roads to help minimise any disruption during construction.
‘A letter has been sent to all residents living along the proposed pipeline route.
‘The potential impact of the pipeline on the environment has been minimised by avoiding the most sensitive areas altogether, such as Great Copse.
‘Where practical the route passes through open space alongside the Hermitage Stream. Experience on other projects has shown that within a few months the restored grass surface will grow back and you would not know we had been there.’
THE pipe diameter will be between 2ft 4in and 5ft 4in (700 to 1600mm)
The top of the pipe will be buried at least 2ft 11in (90cm) below ground level.
A 32ft-wide area needs to be protected from future development along the proposed route of the pipeline. This is to allow for construction and future maintenance of the pipeline.
Construction will take place in small sections.
It is expected the entire reservoir and its infrastructure will take 10 years to build. A formal planning application has yet to be submitted. To see the route map visitportsmouthwater.co.uk
