construction of the first wetland at Pintail Lake in 1978, there has been a
gradual evolution of the wetlands. In 1985 a major expansion occurred with the
construction of Redhead Marsh.This surge of construction was required as
effluent volumes produced began exceeding treatment and disposal capacities.
The present system is designed to handle 1.42 million gallons of wastewater per
day to serve a population of 13,500.
The system was
designed to integrate several lakes and marshes into an effective wetlands
complex. Flexibility in management options was built in to accommodate changes
from year to year. The water delivery system was designed to provide additional
treatment before the effluent reaches Redhead Marsh.
Operation & Monitoring
techniques used in operating the wetland complex involve the management of the
water. The quantity, quality, and delivery routes are varied to manage the
wetland habitat. The flexibility designed into the system allows a variety of
management options. For example, water control structures with adjustable water
boards are used to hold water levels at desired levels. Water can be diverted
away from some ponds to allow them to dry up. This is desired to allow for
maintenance and to accomplish vegetation management goals.
Monitoring of the
wetlands is conducted in accordance with the requirements of the Arizona
Department of Environmental Quality by the City of Show Low. Additional
monitoring is conducted by the Arizona Game and Fish Department and the U.S.
progresses through the system, water quality improves. For example, secondary
effluent coming from the polishing ponds flows into Telephone Lake, then into
an open channel which delivers it to the riparian area. After the riparian
area, the water flows into another open channel and is finally delivered to
pond one of the Redhead Marsh. During this delivery process the water quality
greatly improves. The following charts show the removal rates for nitrogen and
phosphorus as water moves through the system.
