Wastewater Treatment Facility


Facility History and Current Operations


The facility was built in 1974.

It used floating surface aerators
in the aeration tanks and digester.
Sludge was dewatered
using sand drying beds.

Modifications since the facility's construction


Construction of a greenhouse enclosure
on the sand drying beds
Installation of baffles and additional flights
in rectangular clarifiers
Conversion of the digester
from a floating surface aerator
to coarse bubble diffused air
Installation of reed bed constructed wetlands
for residuals reducution and holding
Upgrading of the Cl2gas feed system
to 150 lb. tank-mounted gas chlorinators
Replacement of the comminutor
with a twin-shaft shredder
Conversion of the aeration tanks
from floating surface aerators
to fine bubble membrane diffusers
Replacement of the digester roof
for better heat retention

The greenhouse and a belt filter press were used until the
Buckland town landfill closed. These are now available as backup.
