Raw Water Systems

Upgrading Ladies Bath Raw Water Systems
The aim of upgrading this raw water system was to maximise the daily flow to the Red hill Treatment Works. The project included: 
  • The construction of an Abstraction Chamber. This chamber is designed to minimise the sediment and therefore convey purer water to the treatment plant.
  • The replacement of a HDPE 63mm diameter pipe with a HDPE 90mm diameter pipe which will carry a larger quantity of water to the treatment plant.

Gents Bath Access Road and Chamber
In 2017/18 Connect St Helena Ltd had the Gents Bath Water System upgraded.  Thus giving CSH more control and monitoring capability of water resources and maximising the quantity of water collected and conveyed to the Redhill Water Treatment Works.  In order to effect construction of the abstraction structure and to facilitate future maintenance, a permanent vehicular access was also constructed, with the access road paved with concrete grass blocks, commonly referred to as BG Blocks.
