Trade waste discharges to sewer must comply with Local Authorities' trade waste bylaws. Often there are limitations on the pH or other characteristics which require treatment on-site before the wastewater can be discharged.

Trident Monitoring Services Ltd consultants can assess the requirements of your site, and supply and install the pretreatment you need. Practical solutions include diversion systems, pH neutralization, settling or sedimentation systems, stormwater/sewer first flush systems, and grease traps or hydrocyclones for oil/water separation.
