Rules & Regulations
The Greater Lawrence Sanitary District (GLSD) is a 52-million gallon per day, advanced, wastewater treatment plant that serves some 168,000 residents whose homes are on public sewer lines. In addition to the piped wastes from homes and businesses, GLSD provides septage disposal for communities throughout the Merrimack Valley and approximately 30 surrounding watershed communities. GLSD monitors incoming septage loads to determine if the waste meets our Septage Rules and Regulations. These regulations protect GLSD’s treatment plant and ensure that waste will receive appropriate treatment before discharge to the environment.
