Village of Castleton

Wastewater Treatment Plant Upgrades

Estimated Cost:
$7.3 M

Facility Capacity:
1.15 MGD

Delaware Engineering has assisted the Village of Castleton-on-Hudson (Rensselaer County) with several water and wastewater projects, including upgrades to its Wastewater Treatment Plant.  Originally constructed in 1987, the plant had undergone only two process upgrades over a 30 year period.

Delaware Engineering completed a system design that included several upgrades including:

A new headworks building that will improve influent screening and grit removal

Installation of a fine bubble diffuser/blower system to improve aeration

Two new secondary clarifiers providing a combined capacity for solids loading in the 2.0 MGD range

Two new return activated sludge (RAS) pumps

Improved aerobic digestion via the addition of blowers and diffusers

Replacing the existing rotary drum vacuum filter with a new sludge screw press

Delaware Engineering helped the Village secure a $1.4 million WIIA grant and low-cost financing from EFC. The project is currently in the construction phase with completion expected in 2021.
