Factory Drainage

Many industrial facilities have interior and exterior drainage systems that discharge to public sewers and watercourses. The day they were laid, the records were probably reasonably accurate. As the years go by, and the site is altered and modified, the records slowly lose reliability. The system may separate domestic wastewater, stormwater and process waste, but errors over time can lead to the water entering the wrong pipe.

Effluent discharges are controlled by environmental legislation. Illegal discharges may result in punitive fines, and paying for the clean-up of any pollution or environmental damage. This can arise from both accidental spillages or gradual pollution incidents.

This can also cost a lot of money. Charging is normally on the basis of volume discharged and occasional samples to determine the pollutant load. Rainwater discharging through the trade effluent channel will be charged at the same rate as factory effluent.

We provide a comprehensive programme of investigation, evaluation, recommendation and solution to facility drainage problems.

Site Investigation
A site investigation begins with a desk study of construction drawings, if any are available, and interviews with maintenance managers and other personnel. This will allow the field techniques to be planned.

System Inspections
Physical inspection of the facility drainage system can help determine the connectivity and directions of flow of drainage assets. 

CCTV Inspection
This is the most effective means of examining a pipeline without excavation.  Although there are certain limitations, a CCTV inspection can determine the condition of a pipe, the exact location of any defects, and whether there are any connections.

Evaluation and Recommendations
The results of the investigations will be analysed by our experienced staff, who will make recommendations as to the appropriate actions. Our engineers can develop the best economic and engineering solutions to drainage problems in the facility. If necessary, the system can be modelled to determine the probability of surcharging or flooding.
