DNREC launches statewide assessment of wastewater systems in manufactured home communities

DNREC has begun a statewide assessment of wastewater and drinking-water infrastructure in Delaware manufactured home communities.

The agency said the project launched publicly on April 7, 2026, and is being carried out with contractor Verdantas. DNREC says the goal is to identify communities with aging, poorly maintained or failing systems and to determine what upgrades are needed.

According to the agency, the effort is funded by U.S. EPA grants and State Revolving Fund money. DNREC says it has identified more than 170 manufactured home communities statewide, and 98 are known to have on-site wastewater treatment or disposal systems.

The project had already started with a desktop review and outreach in late 2025, and field assessments began in March 2026. DNREC says it is now moving from planning into active community review and site visits.

The assessment is a public-policy infrastructure story with direct implications for residents in manufactured home communities that rely on older water and wastewater systems. The agency says the work is intended to help pinpoint where environmental health risks and infrastructure gaps may exist.

DNREC’s project page says the assessment will continue as communities are reviewed and data are collected.
