HP monitors the quality of wastewater discharges at operational sites where monitoring is required under applicable local regulations and discharge permits, including imaging and printing product manufacturing facilities. Water discharge quality at these sites is periodically verified through an independent third-party testing, where required, to confirm compliance with applicable legal requirements, local codes, and regulatory standards, consistent with HP’s Environmental, Health, and Safety Policy. 

Additionally, all HP operational sites are required to implement enterprise-wide procedures to prevent unauthorized pollutant discharge into wastewater and to prevent untreated wastewater discharge directly into surface water or groundwater. All HP latex inks are made in a factory using 100% reclaimed water. All water used for our latex inks undergoes an in-house water treatment process to meet specifications for ink quality. The factory performs online, real time organic and inorganic testing weekly to ensure that the purity of the treated reclaimed water meets specifications. 

In 2025, HP had no violations for non-compliance with local discharge limits.¹

¹ Water discharge and/or evaporation rates are estimated. Upon receiving all invoiced water withdrawal and discharges and performing estimations on the withdrawn water to fill in gaps, the average rate of discharge for those sites with invoiced withdrawals and discharges, where the rate is not 100%, is calculated. The sites comprising the average rate of discharge are reviewed for reasonableness of inclusion. The discharge rate is applied to all sites in the portfolio.
