Rules & Regulations

The Greater Lawrence Sanitary District (GLSD) is a 52 million gallon per day, activated sludge, wastewater treatment plant that serves approximately 168,000 sewered residents. In addition to the piped wastes from homes and businesses, the GLSD provides septage disposal for communities throughout the Merrimack Valley and approximately 30 surrounding watershed communities.

The Massachusetts Department of Environmental Protection has established 100,000 gallons per day as the District’s maximum receiving capacity of septage. The GLSD monitors incoming septage loads very closely for acceptability.
