Company

Overview

1982

Founded

The company was established in 1982, marking the beginning of its journey as a water purification contractor.

Four decades

Experience

Over 40 years, the company has evolved into a full-service innovator and leader in water treatment solutions.

It evolved into a full‑service innovator, designing, fabricating and commissioning modular water treatment plants across the UK.
Its financial growth is anchored in delivering award‑winning, cost‑efficient engineered plants, often via offsite assembly and pre‑commissioning.
Typical projects range from ceramic membrane filtration to bespoke ultrafiltration and ion‑exchange systems for water and wastewater.
RSE’s Innovations Hub adapts breakthrough tech—like MABR, nature‑based and zero‑chemical systems—from renewables and other sectors.
It stands out with transportable, 3D‑BIM‑designed plants assembled in clean‑factory settings, minimizing onsite disruption.
Facilities span from Inverness to London, enabling rapid deployment of modular solutions for varied urban and rural clients.

Culture + Values

“Commitment to operational Zero Harm and placing safety first in every situation.”
“Technical excellence through ongoing investment in emerging technologies and sharing expertise.”
“Customer success via transparency, ongoing communication and partnering from first meeting to project completion.”
“Nurturing personal growth by encouraging clear expectations, training plans and career development support.”
“Honesty and integrity in all relationships, led by example through ethical and open communication.”

10% Reduction

Emissions Performance

Achieved a 10% reduction in operational carbon emissions per £M revenue in the latest fiscal year.

25% Carbon

Construction Efficiency

Modular off-site construction reduces carbon emissions by up to 25%, also cutting site traffic by 95%.

Operational Net Zero (Scope 1+2) by 2030; full Net Zero (Scope 1, 2 & 3 including embodied supply chain carbon) by 2035.
Introduction of HVO fuel across sites, plus EV charge‑points and low‑carbon commuting schemes.
Support for verified offset projects (Verra, Gold Standard, UN CER) via Carbon Neutral Britain including kelp restoration, mangrove blue carbon and Costa Rica reforestation.
Innovations include first ceramic‑membrane water plant in Scotland; products designed to help clients meet Net Zero targets.

Inclusion & Diversity

Graduate and Apprenticeship programmes to develop early‑career talent.
Employee health & wellbeing mission: erasing stigma around mental health; official supporter of Lighthouse Construction Charity.
