Interestingly, members of the Lead-in-Water Subcommittee and the Copper-in-Water Subcommittee reported contrasting challenges, as presented by their representatives. Consistent with this column’s theme of what keeps water professionals up at night, we asked subcommittee members to reflect on their most pressing challenges. These topics present significant challenges and are being addressed by various subcommittees. How has the COVID-19 pandemic affected building hydraulics and water quality?.How should premise plumbing be handled, considering it falls in the nonutility-owned portion of the service line? and.How can we improve water quality in hot water systems?.How can we clean premise plumbing from accumulated inorganic contaminants?.How can we control inorganic contaminants (e.g., lead and copper)?.How can we control microbial regrowth (e.g., nitrification and Legionella) in buildings?.Topics of interest to the Premise Plumbing Committee come from questions posed by AWWA members: The Premise Plumbing Committee now has approximately 120 members, representing academia, consultants, equipment providers, industrial partners, federal and local governments and several groups outside of the association.
The committee’s mission statement is “to synthesize industry knowledge and convey information that improves building water quality.” It became an independent AWWA committee in early 2020. To help accomplish the policy’s goals, an AWWA subcommittee was created - Premise Plumbing: Beyond the Meter - under the AWWA Distribution System Water Quality Committee. Reflecting the need to preserve water quality until it reaches consumer taps, AWWA adopted a policy statement on premise plumbing in 2018 that stresses two points: AWWA encourages water systems to establish comprehensive policies and operational goals that are designed to protect water quality in premise plumbing and AWWA supports and encourages collaboration among water systems, public health agencies, property owners and other stakeholders to develop measures for maintaining water quality that meets or surpasses regulatory standards and requirements in premise plumbing.
