Addressing Septic System Challenges in Virginia: Current Status and Future Solutions

More than one million properties in Virginia rely on Onsite Sewage Disposal Systems (OSDS). As of the 1990 Census, 70% of residents utilized public sewage, while 28% depended on septic systems. Annually, approximately 18,800 new systems and 2,400 replacements are installed. The latest legislation, SB 1509, aims to utilize the Water Quality Improvement Fund, but funding availability remains uncertain. Key issues include cost estimates ranging from $7,000 to $20,000 per installation and ongoing maintenance costs of about $200/year. Local agencies express concerns over staffing and compliance.
