Introduction
Recently, the poor management of underground utility caused
stopping of water and electricity supplies. And for serious
accident may cause gas explosion and vitally human injure. In
order to reduce the probability of damaging the underground utility,
Underground Utility Mapping Survey is the primary tool for
statistically digitalizing and managing the underground properties.
Waterland must provide you one-stop professional engineering
services for solving the unclear underground condition and
enhance the level of management for the underground utility. Our
company aims to satisfy our clients from planning of underground utility mapping to the stage of construction of GIS system.
Background Theory
A specific frequency signal of electromagnetic wave can be induced onto the metallic underground utility
services through a direct connection of an alternative current. The specific signal can be obtained above
ground by using a receiver and thus the information of the alignment and depth of the utility services can
be acquired accurately.
Applications
1. Detecting the alignment and depth of underground utility services.
2. Managing the utility property by using the utility record drawings.
3. Designing of the utility layout.
4. Reducing the project risk arising due to damaging of underground utility
services during the construction works.
5. Reducing the project cost.
6. Satisfying the statutory requirements of "the Electricity Supply Lines (Protection)
Regulation Cap 406".
