Sewage management is a tough, dirty job. But someone’'s got to do it. So why not get a little help from the sun? This was the approach taken by the Camden County Municipal Utility Authority in Camden, Jersey.

"“The amount of sewage produced by any sizeable city is simply enormous,”" said Thomas Körner, General Manager of Canadian Solar USA. "“And it goes without saying that when one is effectively running a clean-up operation of this magnitude one wants to use sources of energy that are as clean as possible,”" he added. 

It doesn'’t make sense to clean up in one area and soil another in the process. This makes clean solar the ideal energy source for waste treatment.” Canadian Solar Inc. recently delivered over 8 MW of solar photovoltaic modules to the U.S. solar power installer and distributor groSolar of White River Junction in Vermont U.S. The modules were specifically purchased for three utility and commercial PV projects. 

Among the three new PV systems is a 1.8 MW solar project at the Camden County Municipal Utility Authority's wastewater treatment plant (CCMUA). The plant makes use of Canadian Solar's monocrystalline PV modules. The system was designed to span open wastewater treatment tanks, so no extra space was required for their installation. More than being space-efficient and environmentally friendly, the system results in substantial cost savings on energy for the municipality.

Thomas Körner of Canadian Solar USA said "Canadian Solar is committed to supporting its valued partners and customers. We were pleased to be selected as module provider of choice by groSolar's experienced team as we continue to expand in the U.S. market."

It is estimated that people in first-world countries produce about 75 litres of waste water per person per day. When one multiplies this number by the hundreds of millions of people who live in North America and Europe the potential for the application of solar solutions in this market is clearly vast.
