Russell Park Sewage Pumping Main Replacement, Downpatrick

Doran Consulting was commissioned by NI Water in relation to the replacement of 1,000m of 500mm HPPE Sewage Pumping Main in poor ground and through school playing fields.

We carried out the design of the replacement pipeline, connections, chambers and associated ancillaries. Approximately half of the pipeline was laid under school playing fields. A strict timeframe was imposed for work to be carried out during the school's summer vacation. This was achieved with agreement from the schoolk in staff in relation to working methods and reinstatement.

To avoid open cut pipelaying directly across playing fields, directional drilling was used over an approximately 100m of the pipeline.
