Overview

Water & Wastewater Construction covers contractors building water and sewer lines, treatment facilities, and related water infrastructure. At ~$57B it is a heavy-civil specialty serving largely public utility and municipal clients, replacing aging pipes and building treatment capacity.

Demand is driven by aging water infrastructure, regulatory mandates (lead-pipe replacement, PFAS treatment, combined-sewer overflows), and federal water-infrastructure funding. It is a stable, regulation- and funding-backed niche within heavy civil, fragmented around regional water/sewer contractors.
