Summary
Machine-generated summaryTo safeguard drinking water quality, Waterbedrijf Groningen (WBGR) and Watermaatschappij Drenthe (WMD) jointly operate a laboratory company called Water Laboratorium Noord (WLN), one of four accredited laboratories in the Netherlands allowed to measure drinking water quality. WLN is housed in a large laboratory building at WBGR's drinking water production site, pumping station PS de Punt in Glimmen. Across four decades the building has grown and needs renewal and expansion. A plan and accompanying design have been drawn up to extend the laboratory building and almost completely refit and renovate the existing building. WBGR is the contracting authority, and project management is handled by a project team from WBGR.
