Keeping your critical infrastructure running — from planned maintenance programmes to emergency response, across water, energy and industrial facilities.

ProStream Group provides ongoing service, maintenance and repair for water treatment plants, pumping stations, power generation facilities, and industrial process equipment. We deploy our own trained and certified engineers, supply only original OEM spare parts, and use advanced diagnostic technologies to maximise equipment uptime, extend asset life and reduce unplanned downtime.

How do we deliver?

• Preventive maintenance contracts — Scheduled long-term maintenance programmes with planned work cards, maintenance schedules, spare parts management and exploitation resource monitoring. Designed to prevent equipment failures and unplanned downtime before they occur.
• Plant operation and management — Full outsourced operation of treatment plants and pumping stations on behalf of the client, including day-to-day management, process optimisation and regulatory compliance support.
• Reactive / emergency repair — On-demand rapid response for equipment failures. Our engineers carry advanced diagnostic equipment, tools and spare parts to resolve issues as quickly as possible and restore working capacity.
• After-sales guarantee services — Post-commissioning support for PSG-delivered projects, covering warranty service, performance monitoring and defect resolution.
• Third-party equipment servicing — On-site service for all equipment, including equipment supplied by other companies — no vendor lock-in required.
• Original spare parts supply — Direct supply of OEM spare parts including molded components, mechanical, electrical and electronic components manufactured to the highest standards. Authorised AUMA service partner.
• Remote monitoring and reporting — Maintenance management software providing clients with real-time visibility on service schedules, spare parts status and costs, accessible from anywhere.
