Binfield Water Treatment Works
Amatola Water appointed AfriCoast as the consulting engineers to provide Professional Consulting Services for the Upgrade of the Binfield Water Supply Scheme (WSS). The Binfield WSS obtains raw water from the Binfield Park Dam and supplies potable water to the surrounding rural villages. The area served by the Binfield Water Supply Scheme is the Tyume River Valley and the Amathole Basin situated immediately north and north east respectively of the town of Alice in the Eastern Cape Province in an area that previously was part of the former Ciskei. The area served now falls within the Amathole District Municipality. The Binfield WTW is located approximately 400m downstream of the Binfield Park Dam, also known as the Tyume River Dam. The works and dam are accessed via a gravel road turn off from the R345 road at Macfarlarn Village, approximately 12,5km north of the town of Alice on the way to Hogsback.
Future Water Demands
For economic and social growth, as well as improving quality of life, Amatola Water has set a minimum standard for potable water supply at 750l per household per day.
Amatola Water instructed that WTW losses of 5% and system losses of 12% be used when calculating the future water demands. This required the WTW be upgraded from 4.8Ml/day capacity to 12Ml/day.
Project Scope
The project included the capacity upgrading of the Binfield Water treatment Works (WTW) including a new final water pump station, 2 x 5Ml bulk storage reservoirs, and the provision of a new 6km x 450mm diameter 20 bar rising main from the WTW to the new reservoirs.
