Executive Summary - Water, Sewer & Infrastructure updated Feb 03rd 2026

Harrison’s water, sewer, and flood-protection systems are aging, under-funded, and increasingly strained by growth and seasonal tourism. Much of the underground infrastructure was built decades ago and is approaching or past its typical service life. Replacement and upgrade needs identified in financial plans and engineering reports exceed current reserve funding and are often deferred.

Water and sewer rates are rising because operating costs are increasing, major components require renewal, and long-term funding gaps remain unresolved. Maintenance is largely reactive rather than preventative, which increases the risk of failures and higher future repair costs.

Flood protection remains a critical risk. Engineering studies have identified seepage pathways and structural limitations in the existing dike system. While grant funding has supported studies and early-stage work, full long-term solutions are not fully funded or built, leaving the community exposed during high-water events.

This page compiles publicly available records, council discussions, and technical reports to explain current conditions, known risks, and why infrastructure costs are increasing. The goal is clarity—so residents can understand the issues before they become emergencies.
