MagnaPlast™ Technical Briefing

Engineer‑Led Technical Briefings on HDPE Sanitary Sewer Manholes

Learn how monolithic HDPE manholes are designed, detailed, and installed for corrosive wastewater service in accordance with relevant ASTM and AASHTO standards.

Join our weekly live briefing or request a private, PDH‑eligible session tailored to your organization’s project conditions.

The content is structured for P.E.s, consulting engineers, project managers, municipal owners, and utility leaders responsible for sanitary sewer design, standards, and field performance.

Why Engineers Are Re‑Evaluating Manhole Materials

Concrete and polymeric concrete manholes have well‑known strengths and limitations in corrosive wastewater service—particularly around corrosion, joints, constructability, and lifecycle performance. This technical briefing series examines monolithic HDPE sanitary sewer manholes from an engineering standpoint: how they are designed, detailed, and installed in compliance with applicable ASTM and AASHTO references.

Join our live, multi‑firm MagnaPlast™ Technical Briefing on Wednesdays from 11:00–11:50 AM CDT.

In this one‑hour session, participants from consulting firms, municipalities, and utility organizations receive a concise but substantive overview of:

  • Wastewater service environments and common manhole failure mechanisms

  • Comparative material considerations for concrete, lined systems, polymeric concrete, and HDPE

  • Monolithic HDPE manhole configuration, including structural core, sump geometry, and connection options

  • Bedding, backfill, traffic‑bearing tops, and grade‑adjustment details based on our installation guidance

  • Key design and installation standards referenced in our documentation, including ASTM F1759, D3350, D2321, F477, and F1417

Use the form below to request a dedicated one‑hour technical session for your firm, municipality, or utility team.

In this private briefing, the core engineering content is adapted to your typical project conditions, such as urban rehabilitation programs, greenfield collection systems, traffic‑bearing installations, groundwater concerns, or specific detail preferences. The session can go deeper into:

  • Project‑type examples aligned with your work and local requirements

  • Preferred connection details, drop configurations, and frame‑and‑cover selections

  • Submittals, drawings, and documentation required for your review, approval, and permitting processes

  • Extended Q&A focused on your standards, specifications, and field challenges

Participants in the organization‑specific session are eligible for 1 PDH and receive a Certificate of Completion suitable for inclusion in their continuing education records, subject to the requirements of their licensing board.
