 <div class=\"tricel-comparison-faq-answer\">\r\n        <p>\r\n          No. A septic tank provides primary settlement and limited anaerobic\r\n          biological breakdown. A packaged wastewater treatment plant includes\r\n          an additional biological process that provides secondary treatment\r\n          inside the unit.\r\n        <\/p>\r\n      <\/div>\r\n    <\/details>\r\n\r\n    <details class=\"tricel-comparison-faq-item\">\r\n      <summary class=\"tricel-comparison-faq-question\">\r\n        Which is better: a septic tank or a treatment plant?\r\n      <\/summary>\r\n\r\n      <div class=\"tricel-comparison-faq-answer\">\r\n        <p>\r\n          Neither system is universally better. The appropriate option depends\r\n          on the site conditions, ground characteristics, available space,\r\n          required treatment level, discharge route, site-assessment report,\r\n          and planning requirements.\r\n        <\/p>\r\n      <\/div>\r\n    <\/details>\r\n\r\n    <details class=\"tricel-comparison-faq-item\">\r\n      <summary class=\"tricel-comparison-faq-question\">\r\n        Does a treatment plant replace the percolation area?\r\n      <\/summary>\r\n\r\n      <div class=\"tricel-comparison-faq-answer\">\r\n        <p>\r\n          Not automatically.
