Engineered Horizons Inc. is installing data loggers on certain fire hydrants throughout Austell which may cause “very minimal disruption” to the water service.

Data is being collected as fire hydrants are flowed as part of the city’s water system hydraulic modeling.

Residents noticing any discoloration to their water are asked to flush their water lines by letting the water run for several minutes.

If the discoloration continues, residents are advised to run a load of water before washing clothes.

Also, residents are asked not to disturb the data loggers.

The purpose of a hydraulic model is to illustrate the effects of changing demand and climatic conditions on the city’s water distribution system, predicting pressures, identifying bottlenecks and demonstrating the effectiveness of proposed solutions.

By testing different alternatives and using the existing system to full advantage, models help minimize the cost of improvements, according to city officials.

Additionally, this modeling will assist the city’s Fire and Emergency Services Department in maintaining its current 4 ISO rating and to help lower that rating in the future.
