2021 International Private Sewage Disposal Code – ICC IPSDC-2021

Scope:
The 2021 IPSDC® establishes minimum requirements for the design, installation, and maintenance of private sewage disposal systems for buildings not connected to public sewer infrastructure. It applies to new installations as well as alterations to existing on-site wastewater treatment systems.

Key Features and Content Highlights:

• Prescriptive Design Framework:
  Emphasizes a specification-based approach, with detailed criteria for site soil evaluations, system sizing, and construction methods based on soil conditions.
• System Types Covered:
  Includes standards for soil absorption systems, holding tanks, cesspools, and various on-site treatment methods for residential and light commercial use.
• Site Evaluation Requirements:
  Mandates specific procedures for analyzing soil suitability and system location based on percolation rates and environmental factors.
• Material and Construction Standards:
  Details minimum requirements for piping, tank construction, backfill, and system layout to ensure long-term health and environmental safety.
• Administrative and Enforcement Provisions:
  Provides guidance for permitting, inspections, penalties, and enforcement, with customizable placeholders for local jurisdictions.
• Coordination with I-Codes:
  Fully compatible with other 2021 I-Codes including the IPC, IRC, and IEBC, making it suitable for jurisdictions adopting an integrated building and environmental code system.

The IPSDC is intended for use by code officials, environmental health agencies, system designers, and contractors working in areas without centralized sewer access. It offers a comprehensive regulatory framework for safe and effective on-site wastewater treatment.
