Pump Station Design in Ireland: What Developers and Engineers Need to Know

Keeping Your Pumps Running Through the Festive Rush

Pump station design in Ireland is one of the most consequential decisions on any residential or commercial development. A poorly specified station results in redesign costs, Uisce Éireann rejection and programme delays. A well-designed one performs for decades with minimal intervention.

Campion Pumps has delivered wastewater pump station solutions for some of Ireland’s largest developments, with over 30 years of experience and a fully in-house team of Technical Designers, Engineers and Software Developers.

When Does a Development Need a Pump Station?

A pump station is required wherever gravity drainage alone cannot move wastewater to the main sewer network. Common scenarios include:

• The development sits in a low-lying or below-gradient location
• The site is a significant distance from the nearest connection point
• The discharge point sits at a higher elevation than the development
• The scale of the development requires controlled pumping to avoid overloading existing infrastructure

For large residential schemes, a correctly designed foul water pump station is a prerequisite for Uisce Éireann approval and final handover.

Key Considerations in Pump Station Design in Ireland

Every site has different requirements. A design suitable for a 42-unit scheme will not serve a 400-unit development.

 Flow Rates and Wet Well Sizing

Every design starts with accurate flow rate calculations across dry weather and peak storm conditions. From this, the wet well is sized to provide adequate storage between pump cycles and to protect the receiving sewer from shock loading.

Undersizing is one of the most common and costly mistakes on Irish development projects, leading to excessive pump cycling, accelerated wear and, in serious cases, upstream flooding.

 Rising Main Design

The rising main carries pumped flows from the station to the gravity sewer network. Diameter, material and gradient all require careful specification. Too small a rising main introduces excessive friction losses. Too large and the risk of septicity, odour problems and compliance failures at the Uisce Éireann connection point increases significantly.

Pump Selection and Variable Speed Drives

Campion works with all leading pump manufacturers and specifies Variable Speed Drives (VSDs) as standard. VSDs adjust output to match actual demand and can reduce energy consumption by up to 70% compared with fixed-speed systems.

 Control Panels, Telemetry, and Uisce Éireann Compliance

Any station taken in charge by Uisce Éireann must meet IW-TEC-800-02 standards, covering wet well design, pump selection, control panel configuration and telemetry integration. Campion designs and assembles its own control panels in-house and installs Campion Connect, its real-time monitoring platform, as standard. 

The design team works directly with Uisce Éireann and county councils throughout the approval process, taking that burden off the developer and targeting first-time approval.

Why a single contractor matters

Multi-contractor pump station delivery creates accountability gaps. When problems arise across separate civil, mechanical and electrical contractors, establishing responsibility takes time. That time costs money.

Campion designs, manufactures, delivers and commissions the entire pump station through one in-house team. Technical Designers carry out hydraulic calculations, surge analysis and septicity analysis from the outset. Engineers manage the build. The software team programmes the controls and monitoring. One point of contact, one set of drawings, one handover package.

On the Glenveagh Properties project in North Dublin, Campion delivered a full network of Uisce Éireann-compliant foul pump stations across a phased development of 3,250+ units, on time and without disrupting build schedules at any phase.

The majority of pre-commissioning work is completed off-site at Campion’s facility in Thurles, Co. Tipperary. Tanks, control panels and pump assemblies arrive on site ready to install, reducing on-site programme time and lowering the carbon footprint of the project.

What to ask a Pump Station Design Partner

Whether you are a developer, a consulting engineer or a main contractor, the questions to ask of any pump station design partner are straightforward:

1. Do they have an in-house design team with hydraulic and MEICA capability?
2. Can they demonstrate Uisce Éireann project experience at comparable scale?
3. Do they manage civil, mechanical, electrical and controls under one contract?
4. Do they offer a service and maintenance programme post-handover?
5. Are they ISO certified and compliant with relevant Irish and EU standards?

Campion holds ISO 9001, ISO 14001 and ISO 45001 accreditations and has delivered pump station solutions for developments ranging from single dwellings to schemes of over 4,500 units.
