Impact-Echo testing on the aqueduct identified debonding and delaminated areas
of the pipe wall.
A helicopter-based aerial
IR survey was conducted
on the entire length of the
aqueduct to find possible
leak conditions.
Hultman Aqueduct construction, c. 1934
Debonded areas detected by IE
Longitudinal GPR surveys
were conducted on over
20,000 feet of the
aqueduct, focusing on
areas found by IR.
Transverse GPR
data showed relative
moisture content in the soil
and showed anomalies at
the pipe-soil interface.
Longitudinal GPR data shows area of high soil
conductivity corresponding to leakage.

Repairs of the Hultman Aqueduct —
INFRASENSE, Inc. received the American
Consulting Engineers Council of New
England (ACEC) Engineering Excellence,
Grand Conceptor Award.
The novel use of nondestructive evaluation
was a key factor in receiving the award.
INFRASENSE, Inc. conducted nondestructive evaluations for the
Massachusetts Water Resources Authority for a major link in Boston’s water
supply — the 18-mile long Hultman Aqueduct.
We combined advanced technologies in Impact-Echo (IE), Infrared (IR) and
Ground Penetrating Radar (GPR) to identify areas in need of repair.
