  • Improve the functionality of the site .i.e. improving parking and access to the site.

Reservoir Linings
The reservoir linings of several reservoirs are being replaced to reduce sediment and improve quality of water, as well as making the reservoir more stable.


Scotts Mill reservoir
The relining of the Scotts Mill reservoir at Red Hill was completed in June 2015.  Two engineers from Butyl Products, South Africa were contracted to lead this project and train our staff in the process for when the time comes to reline our other reservoirs.

The relining of reservoirs at Longwood - Longwood 1, Longwood 2 and the Millfield reservoir were completed in April 2016. 
Harpers 1 and Hutts Gate 1
In January 2018 a contract was signed between Connect Saint Helena Ltd and Butyl products Ltd to reline two of our existing reservoirs, namely Harpers 1 situated in the Red Hill Water Zone and Hutts Gate 1.
In May 2018, two technicians from Butyl arrived on island to work with the Connect Saint Helena Ltd team, to reline both these reservoirs in a period of 8 days.
Enlargement of Harpers 3

The construction works commenced in January 2016 and on the 30th July 2016, the installation of the lining in Harpers 3 was completed.  This new lining is expected to last around 30 years.

The Harpers 3 Reservoir is an existing butyl lined reservoir. The reservoir was excavated into the hillside and cut slopes on the southern and eastern sides of the reservoir were unstable and collapsing.  Embankment slopes within the reservoir were also unstable and previously collapsed. 
The main purpose of this project is to stabilise the unstable cut and embankment slopes and to significantly enlarge the storage volume of the reservoir,  from 8,000 cubic metres to around 20,000 cubic metres.

For a detailed account of the steps that were taken to complete this project please visit our Download Library under the heading Water Treatment and Networks for the related article.

De-silting of Harpers 2 reservoir
In April 2019 works started to remove the silt from Harpers 2 reservoir that have built up over the years, thus improving the water quality that comes into the Water Treatment Works and distributed to consumers.  This Project was completed at the end of May 2019.
