The Valley Creek Wastewater Treatment Facility set a new standard as part of a $14,000,000 (1976 dollars) facility owned by Jefferson County, Alabama. The plant provided primary and secondary treatment and stored menthane gas from the digesters to supplement the gas powered air blowers for the primary and secondary aeration facilities. 

One of the Principals of DAC served as the Office Engineer (2nd in charge) in the on-site office for the general contractor, Blount Brothers Construction, Inc.

The project was built using a federal grant with the remaining funding from state and local agencies.
