What is Green About ALCOSAN?

Operating, Promoting and Thinking Green!
From our energy recovery process to the beneficial use of wastewater residuals and even to our annual Open House and scholastic programs, ALCOSAN is committed to environmental stewardship not only in what is preached, but also in what is practiced in the daily operation of our wastewater collection and treatment system.  Below are just some of the ways that ALCOSAN operates, promotes and thinks Green.  For even more information, please download our What is Green About ALCOSAN? brochure here.

Pollution Prevention
ALCOSAN’s commitment to our ratepayers and our region involves taking a lead in the stewardship of our environment, including the natural resources we take for granted.  Our pollution prevention initiatives not only dictate how we manage and process wastewater, but also act as a vehicle for helping our customers understand their role of ownership in the environment. 

Pollution prevention is truly everyone’s responsibility. Please explore further to find out what ALCOSAN is doing to make clean waterways a reality and also what you can do to be an environmental steward in your home and community.

BIOSOLIDS – Waste that’s anything but wasteful
Biosolids are nutrient-rich processed organic material produced through wastewater treatment. This organic material can then be used for a myriad of applications, including increasing soil’s ability to provide nourishment for crops, accelerated composting under controlled conditions, development as pellets valuable in cultivating citrus fruits, and finally as a building material when combined with conventional clay and shale.

Environmental Compliance
The Division of Environmental Compliance ensures that ALCOSAN complies with environmental laws. It is ALCOSAN’s primary point of contact with environmental regulatory agencies for routine issues, permit applications and reporting. The Director of Environmental Compliance initiates environmental policy for review and discussion by senior staff, and participates in review of other ALCOSAN policies. The activities of three departments are coordinated to ensure that permit requirements are met, treatment byproducts are reused or disposed of properly, and industries are complying. The Director also provides legal counsel to the Executive Director on environmental and related issues.

Environmental Compliance’s  primary responsibilities are to protect ALCOSAN’s customers, as well as the treatment plant; to recover and reuse the valuable resources of ALCOSAN; and to interact honestly and fairly with regulatory agencies, industry and ALCOSAN’s valued customers. 

Environmental Compliance includes the following departments:

  • Environmental Audit Department is responsible for detailed compliance reviews of ALCOSAN’s process, reporting and waste disposal management.
  • Residuals Department is responsible for management of byproduct, beneficial reuse or disposal and researching new opportunities for reuse or recycling.
  • Industrial Waste Department is responsible for laboratory services for process control and industrial regulation and operating an industrial regulatory monitoring program.
