Pumping & Bailing - Long Island, NY

Well Point De-watering

We pride ourselves in our pumping equipment. From small pneumatic diaphragm systems to a large pump system we heave it and it’s ready to go. From very deep footings into groundwater or sewer-line installations, we can perform total project with our own equipment.

  • Large diesel powered multi point systems
  • Small pneumatic pump systems
  • Gasoline diaphragm pump 4” header systems


It is occasionally necessary to “draw down” groundwater to complete an underground construction task effectively.

Some contractors will attempt to perform “on the fly” or work underwater at a reduced price.

Obviously, quality control of such operations is negligible or non-existent.

Please use discretion - "bargains" often end up far more expensive than doing it right in the first place.

Excav Services is a NYS DEC licensed well driller, we can take your project from concept to completion obtaining all necessary permits and formulating filtering systems as needed to preserve our natural recourses. We offer two sizes of systems, and three types of prime movers for flexibility.
