The city's wastewater plant is at Awatoto, and treated wastewater is discharged into Hawke Bay via a {{cvt|1.5|km|4=1|}} outfall pipe. The Awatoto wastewater plant and outfall were opened in 1973, replacing the previous outfall at Perfume Point in Ahuriri. The wastewater plant was initially a comminutor station and was upgraded in 1991 with milliscreens and in 2014 with [[Trickling filter|biological trickling filters]].<ref>{{Cite web  |title=Awatoto Wastewater Treatment Plant |publisher=Napier City Council |url= https://www.napier.govt.nz/services/water/sewerage/treatment-plant/ |access-date=1 February 2022 |website=napier.govt.nz}}</ref>
