Case Study: City of Forest Grove achieves a compliant, all non-lead service line inventory with 120Water

City of Forest Grove verifies 351 lines and eliminates unknowns with 120Water

The City of Forest Grove, OR partnered with vendor 120Water to overcome the challenge of completing a compliant service line inventory for the Lead and Copper Rule Revisions. The city lacked data on customer-owned service lines and needed a clear methodology to use a statistical analysis approach for verification, as allowed by the Oregon Health Authority, in order to minimize unknowns before their submission deadline.

120Water provided Professional Services and clear guidance on the statistical requirements, delivering a randomized list of locations for the city's team to verify. This support enabled Forest Grove to visually inspect and verify all 351 required customer-side lines efficiently. As a result, the city achieved the first all non-lead inventory on the 120Water platform well ahead of schedule, eliminating all unknowns and avoiding the need to send any notifications to residents.
