Farlington Reservoir No. 9
Filtration and pumping of supplies of water to satisfy the needs of the community from local springs has existed at Farlington since 1860. The current reservoirs are fed from 23 natural springs around the Langstone Harbour area and the supply is considered the largest of its kind in the UK.
The design and construct contract of Reservoir No.9 for Portsmouth Water Ltd by main contractor Dean & Dyball was built on the footprint of two older redundant reservoirs no longer able to pass the strict water tightness tests. The new reservoir was more than 230 metres long, 53 metres wide and more than 5 metres high. The structure comprised a total of 470 columns supporting the reservoir and chamber area including 1800 tonnes of BRC reinforcement provides a capacity of 45 million litres of water sufficient to supply the needs of 200 000 people in the area.
