Hemphill/Chattahoochee WTP – Instrumentation & Controls System

inactive / design

The implementation of the Water Supply Program is the most substantial water system investment since development of the Chattahoochee Water Treatment Plant (WTP). This program will address acute weaknesses in the raw water supply infrastructure identified in recent facility assessments. This project is as crucial to the Water Supply Program as it is to the future efficient operation of Chattahoochee and Hemphill WTPs. The existing instrumentation and control systems at these facilities are old and obsolete. The new instrumentation and control system will be used to automate the operation of both plants and the tunnel system from the Chattahoochee River to the Quarry. The scope of this project includes: Replacing three (3) programmable logic controllers at Chattahoochee WTP Replacing three (3) variable frequency drives of the distribution pumps at Hemphill WTP Replacing one (1) programmable logic controller at Hemphill WTP Also included in the scope of this project is the tying of the Division 1 and Division 2 areas of Hemphill WTP into the plant’s supervisory control and data acquisition (SCADA) system.
