Urgent Requirement–Drainage / Wastewater Assessment (N.IRELAND)

We are seeking assistance from a suitably qualified Civil Engineer, Drainage Engineer or Water Engineer to prepare a short technical note in support of a live planning application in Northern Ireland. Background The planning application relates to an existing public house and adjoining retail unit.

A key issue has arisen regarding wastewater generation and the potential impact on the NI Water network. We require an independent professional assessment of whether the removal of the existing deli operation is likely to offset, or potentially exceed, any increase in wastewater generation associated with the proposed use. Scope The successful consultant would be required to: • Review photographs and information relating to the existing deli operation. • Assess the likely wastewater generation associated with the existing deli use. • Consider the proposed arrangement and likely wastewater generation following removal of the deli. • Provide an opinion on whether overall wastewater generation is likely to remain similar, reduce, or increase. • Prepare a short technical note on company headed paper suitable for submission to NI Water and the Planning Authority. Requirements • Relevant qualification in Civil Engineering, Drainage Engineering, Water Engineering or similar. • Experience of drainage design, wastewater assessments or NI Water applications. • Ability to provide a professional opinion on company headed paper. • Quick turnaround essential. Timescales This is an urgent commission and we would ideally require a draft note within 24–48 hours. Please contact Ryan Milligan at Planning Experts if interested
