Innovative solutions for wastewater and biosolids management

At the Greater Lawrence Sanitary District (GLSD), protecting the Merrimack against untreated wastewater is our mission.  It’s what motivates every one of us as we search for more ways – and better ways – to handle wastewater and biosolids management across our district.

 

Our Story

Wastewater Management

In five major steps, we treat wastewater using a responsible treatment process that maintains the health of the Merrimack river.

Solid Waste Management

Transforming biosolids and food waste into fertilizers and fuel, we take the lead on reducing the carbon footprint of Greater Lawrence.

Motorhome Septic Disposal

As a community service, we provide a free, sustainable solution for RV and camper septic disposal onsite at our facilities.

Industrial Pretreatment

We put the safety of residents first by enforcing EPA regulations for industrial wastewater management.

Promoting clean rivers and green economies.

At GLSD, our commitment to capital improvements and to advocate for resources that will allow us to continue to reduce Combined Sewage Overflow (CSOs) events demands that we keep our communities informed about the needs of a changing tomorrow.

From converting food waste to fuel to maintaining sewer infrastructure, it’s important that residents understand the what, why, and how of these complex systems – what they can reasonably be expected to deliver, and their practical limitations, particularly in the face of populations shifts and climate change.
