MAINTENANCE DISTRICT 22A, OAKHURST
Maintenance District 22A, Oakhurst, is located in the community
of Oakhurst on State Highways 41 and 49, in Madera County.
The district provides sewer service to both commercial and
residential developments.
The sewer system consists of gravity and force main collection
systems, nine pumping stations, an oxidation ditch, chlorine
disinfection, treated effluent storage pond, irrigation
pumping stations, approximately 85 acres of treated effluent
disposal sprayfields, and sprayfield irrigation runoff return
pumping stations. The collection system recently underwent
major rehabilitation including pipe repairs, new force main
to the treatment plant, new gravity main river crossing,
new main lift station, and replacement or repair to several
manholes.
Two original sewage pumping stations near the Fresno River
at Road 426 and Chapel Hill are in fair condition now, but
will eventually need to be rehabilitated. The old main lift
station at State Highway 41 has been abandoned as part of
the collection system upgrade project. The new main pumping
station, which pumps approximately 90% of the daily plant
flow, has the capacity to pump approximately 1,000,000 gallons
of wastewater per day.
Of the three small pumping stations that serve apartment
complexes along Victoria Lane, two are in need of rehabilitation
due to the corrosive effects of sewer gasses. The pumping
station serving Enterprise Center is in fair condition.
Also in fair condition is the pumping station on Redbud
Drive at the river. Requirements to modify the force main
and lift station along the Redbud collection line will be
placed on developers to accommodate the anticipated increase
in flows as growth occurs. A back-up generator will also
be considered.
Reconstruction of the wastewater treatment plant was recently
completed, although it has not yet been certified by the
state. The new facility will provide for more advanced treatment
capable of removing nitrates from the wastewater. Once certified,
it will also have a septage receiving station to treat septic
tank pumpings from Eastern Madera County. Part of the overall
plan for this facility includes the ability to return treated
and reclaimed wastewater to the community for reuse in the
irrigation of large, open space parcels.
The system has generator backup at the main pumping station,
treatment plant and sprayfield run off return pumping stations.
The district also has trailer-mounted generators available
to run the remote pumping stations, but not the irrigation
pumping stations. The collection system is equipped with
alarms and auto dialers to notify district personnel in
the event of an emergency.
