Numerous local authorities around the United States are believed to be studying tax-like fees to homeowners and requirements for regular septic tank maintenance. However, they are not always getting their way. In Idaho, lawmakers shut down new regulations for septic-tank drain fields because they feared it would hinder Idaho's economy, especially during a recession.
In Maryland, lawmakers in April, 2009, passed a measure to require homeowners within one thousand feet (300 meters) of tidal waterways to upgrade their septic systems. Upgrades are expected to cost about $12,000 per system, but money in the Maryland Bay Restoration Fund may be usable for the purpose.
As the nation moves toward more national water-quality and wastewater treatment standards, these types of governmental regulations and fees are likely to increase.
Caveat: Check with your local authority for regulations specific to your area.
