Wastewater Recharge: Water Quality and Operations

David M. Esposito Don Armstrong David G. Eaker George A. Brinsko

The Green Valley Wastewater Treatment Facility began operations in its current configuration in 1981. It treats approximately 1 million gallons per day of municipal wastewater, with disposal through percolation beds. At the present time, it is Arizona's largest operating controlled ground water recharge facility. It is the only wastewater treatment plant discharging through percolation with no alternative methods of effluent disposal. Percolation bed performance is thus a critical parameter for continued operation of the facility. The recently enacted Arizona Environmental Quality Act requires maintenance of ground water quality at drinking water standards. Ground water quality protection is also a critical factor. This paper presents a summary of important operating and ground water quality parameters related to the facility's operation over the past five years.

Groundwater Processes and Modelling - Part 6

CSIRO Publishing eBooks (1998)

Don Armstrong Kumar A. Narayan

This booklet outlines the properties of geological materials which enable them to accept, store and transmit groundwater, together with a description of the principal types of aquifer which are commonly found to occur in the field. Sources of groundwater are described in order to provide an understanding of the hydrogeological modelling exercise. The governing equations for steady state and non-steady state (transient) groundwater flow, are presented together with a brief overview of a range of modelling techniques, including both analytical and numerical models, the use of diffuse recharge as a model calibration tool and recent developments in the field of inverse modelling are also discussed.

Groundwater Problems - General Report

Fifth Australia-New Zealand Conference on Geomechanics: Prediction Versus Performance; Preprints of Papers (1988)

Don Armstrong

Three papers concerned with large scale permeability testing at Fitzroy Canal, groundwater inflow into two mines in the south Sydney Basin and the relationship between rainfall and landslide occurrence at Lake Macquarie are critically reviewed. Alternative models or interpretation of observed data are presented.
