The UAJA based its choice on an operation that is simple to operate, has flexibility for a range of conditions, is economical, and has the ability to produce an end product for horticultural and agricultural reuse.
At the same time as this project was being undertaken the UAJA was starting a $16.6-million process upgrade and hydraulic expansion of its wastewater treatment plant.
One of UAJA's major concerns about selecting a new biosolids disposal method was odors.
Most only took away small quantities and the UAJA did not have the staff or facilities to handle the orders.
As part of its successful "marketing" program UAJA produced flyers and a newsletter describing uses for compost.
