What is the minimum lot size requirement for On-Site Sewage Facilities with public water in Texas?

In Texas, the minimum lot size requirement for On-Site Sewage Facilities (OSSF) connected to public water supply is indeed 1/2 acre. This requirement is established to ensure that the sewage disposal systems have adequate area for proper operation and to minimize potential environmental impacts, such as groundwater contamination. When public water is available, a smaller lot size is permissible compared to areas relying on private water sources, which typically necessitate larger lot sizes to provide appropriate separation distances from the sewage facilities.

This 1/2 acre requirement facilitates effective management of sewage systems while supporting public health and environmental standards. It’s essential for land surveyors and developers to be aware of this regulation when planning and designing properties with on-site sewage systems, ensuring compliance with state regulations for sustainable land use.
