WATER TREATMENT FACILITY UPGRADE
BRATTLEBORO, VERMONT

The Brattleboro, Vermont Pleasant Valley Reservoir Water Treatment Facility was originally constructed in 1988. Since that time the facility has experienced difficulties with coagulation and operation of the adsorption clarifier/filters. The Town of Brattleboro initiated an evaluation of the facility in 2000 to identify deficiencies and recommend improvements. As a result of that evaluation the following improvements were included in a comprehensive facility upgrade:

• Increase raw water pipe diameter for additional coagulation contact time.
• Building addition for equipment.
• Addition of a fourth clarifier/filter unit.
• Addition of filter rinse provisions.
• Building addition for air handling equipment, storage and maintenance.
• Modification to existing lagoons.
• Construction of freezing/drying bed.
• Controls, instrumentation and SCADA replacement.
• Wide Area Network.

KEY FEATURES

• Significant reduction in operating staff labor requirements.
• Maintain facility flow and uninterrupted supply to the Town of Brattleboro during construction.
• Annual and long term cost savings for residuals handling and disposal.
• Enhanced public health protection by eliminating potential turbidity spikes, giardia or cryposporidium contamination.
