The benefits of a flow and load survey

A flow and load survey can potentially result in huge cost savings when performed in advance of construction and refurbishment projects.

Before a treatment works or pumping station is modified it is important to know exactly how the existing system functions by measuring the loads that are being placed upon it.  

A flow and load survey provides a measure of what is happening within a treatment process at any moment in time. It can identify problems in a treatment works or hydraulic system before costly remedial works are undertaken.

The potential cost of getting a design wrong, due to a lack of flow and load information, is likely to be far greater than the cost of a survey.  

Many flow and load surveys are driven by a waste water treatment works failing its quality consent limits or being required to accept increased volumes or strengths of effluent.  

Older treatment works, particularly those found in rural areas, were often not designed to treat the types of effluents they are now receiving.

The surveys we perform involve taking accurate measurements of all the relevant process variables so that designs and modifications are based on the known diurnal flow patterns and effluent strengths being received.

When a project is completed a flow and load survey can confirm that the new plant and equipment is performing correctly and that contractual obligations have been fulfilled.
