About the Role
As a Trade Effluent Investigation Technologist, you will visit business customer sites to investigate trade effluent discharges and agree on action plans to ensure responsible wastewater management. This hands-on role involves building strong relationships with customers, addressing on-site problems, and stepping in when issues arise—whether that means creating action plans or gathering evidence for enforcement. You will work closely with operations teams on pollution incidents such as blockages or unusual substances entering treatment works, occasionally raise trade effluent charges for non-compliance, and prepare clear, detailed records and reports that withstand scrutiny. A full UK driving licence and access to a suitable vehicle are essential as travel to customer sites is required. Your work will directly contribute to protecting both the water network and the environment.

Benefits
Competitive salary with performance-related pay up to 10% of salary, 24 days holiday per year increasing to 28 with length of service plus bank holidays, generous pension scheme through AON, and a wide range of health and wellbeing benefits including annual health MOTs, physiotherapy, counselling, Cycle to Work schemes, shopping vouchers, and life assurance.
