Preventative Maintenance of Water and Wastewater Treatment Systems and Plants

Weston & Sampson  provides hands-on, scheduled repair and maintenance of water, wastewater, and stormwater treatment systems and plants. Our staff of licensed electricians and plumbers, mechanical piping technicians, welders, and laborers, is supported by a fleet of more than 50 maintenance vehicles. These fully equipped trucks include spare parts, tools, cranes, and support equipment required to conduct repairs on site. For those complex repairs requiring off-site work, we support our staff with our own off-site repair facilities, allowing us to shorten turn-around times for equipment repair.

Our clients include municipal water and/or sewer departments that utilize their own in-house staff as first responders, but call upon Weston & Sampson in the event their staff encounters problems requiring outside support or during vacations and short-term staff shortages that necessitate support until the client can restore its labor force to desired capacity.

Our clients also include private utility owners such as property management companies, condominium associations, industrial and commercial plant managers, facility managers, and property owners who have in-house staff to respond to initial alarms, but require the specialized expertise and capabilities of Weston & Sampson.
