1xINTERNET are regular contributors to the Drupal project.
Umwelttechnik BW GmbH (UTBW), is the state agency for environmental technology and resource efficiency in Baden-Württemberg, Germany. The agency brings together stakeholders and professionals in the relevant fields of environmental technology, facilitating strategic project development at a regional level.
UTBW faced the challenge of a fragmented digital ecosystem spread across multiple CMS platforms and static websites, each with its own design, search, and maintenance demands. This lack of integration created inefficiencies in security, upkeep, and usability. To address these issues, 1xINTERNET partnered with UTBW to unify its online presence on a modern Drupal multisite platform.
The new solution consolidates content and microsites into a central resource that provides information, events, established working groups, and operational support for funding programs, helping companies across the state move toward a more environmentally compatible future. A powerful global search and filter system enhances access to content across all sites, while the platform itself delivers a secure, scalable, and accessible foundation that balances compliance, performance, and user needs.
About the project
The client: Umwelttechnik BW GmbH
Since 2011, a dedicated state agency in Baden-Württemberg has served as a central hub for environmental technology and resource efficiency, bringing together information, initiatives, and experts in the field. At the regional level, it connects stakeholders from business, science, and politics to foster strategic project development while advising and supporting companies.

Multisite Solution Connecting Business, Research, and Policy
Umwelttechnik BW (UTBW) set out to build a central digital hub that unites knowledge, services, and stakeholders to drive sustainable innovation and accelerate strategic projects. In collaboration with 1xINTERNET, UTBW replaced a fragmented landscape of CMS platforms and static websites with a unified Drupal-based multisite solution. Previously, sites had separate design, search, with no data exchange, preventing meaningful connections.
The new multisite platform delivers consistent design, secure hosting, and integrated maintenance while enabling scalable growth and long-term sustainability. Powered by Elasticsearch, an advanced search function gives users fast access to companies, funding programs, projects, news, and events, with curated topic pages providing intuitive entry points into UTBW’s diverse offerings.
| Unified data architecture | Search and filter functionality | Brand consistency |
| The multisite management system introduced a shared code base that provides a consistent foundation for all sites. By bringing together data from six different websites into a single architecture, the platform allows content to be shared across the platform while maintaining the unique identity of each site. | A faceted search and filter system, powered by Elasticsearch and React and integrated into Drupal, provides users with access to all agency resources, from companies and funding programs to projects, awards, and news, through a single search box. | Consistent UI and UX design updates, aligned with UTBW’s brand guidelines, creates a cohesive visual identity across platforms. The responsive, mobile-first design strengthens brand recognition, reinforces system reliability, and builds user trust. |

Performance impact in numbers
|
108% |
83% Increase in conversions |
26% Increase in user engagement |
98% Responsiveness |
The 2024 platform optimisation reshaped UTBW´s digital performance, driving growth in user acquisition, engagement, and technical reliability. Traffic surged all channels, direct +186%, organic +222% and campaigns +2,064%, with corresponding increases in conversions and engagement.
Returning visitors spent 26% more time on site demonstrating that platform improvements create genuine value for users who come back. At the same time, engagement among new users remained strong despite the traffic increase, proving that acquisition kept pace with the rapid growth.
User behaviour also shifted, once dominated by desktop (90%+), mobile now represents 18.2% of visits and outperforms desktop in Core Web Vitals. Mobile users benefit from faster load times (82.5% good LCP) and near pear-perfect responsiveness with 98.4% INP (Interaction to Next Paint).
The results demonstrate that the technical modernisation strategy delivered measurable business value combining superior performance and scalability while serving a growing user base.
From the client:
For us, the new website was a revolutionary step towards the digital linking of all services offered by our state agency as well as the stakeholders involved, thanks to the networking of all content and the intelligent search with suggestions for keywords. At last, users can not only find the information they are looking for, but also see additional, relevant content. The project has been a great success so far and we look forward to further collaboration!"

Why Drupal was chosen
A unified Drupal foundation
UTBW was already running on Drupal 7 & 8 and the state agency was both familiar and satisfied with Drupal. They wanted to continue using Drupal for future development . Transitioning to a unified Drupal 9 codebase created seamless connectivity across all sites while preserving the individuality and unique content of each. The multisite architecture simplifies maintenance, lowers recurring support and update costs, and ensures consistent functionality, security, and user experience throughout the entire network.
