The Fly-tipping Action Wales (FAW) partnership, funded by the Welsh Assembly Government, is using the technology to map hotspot areas of fly-tipping.
Latest figures show that more than 48,000 incidents of fly-tipping were recorded in Wales between April 2009 and March 2010. The cost of clearing up the problem is £3m.
In Caerphilly, 1,560 incidents of fly-tipping were recorded during the period.
The pilot scheme will see a total of 53 GPS units used across nine local authorities allowing enforcement officers to record cases of fly-tipping.
Each case will be recorded and mapped out by location, size and waste type by Fly-tipping Action Wales across the Valleys Regional Park area.
Gary Evans, project manager for Fly-tipping Action Wales in the Valleys Regional Park, said: “More than £25 million is being injected into The Valleys to help maximise the area’s potential and we cannot sit back and let fly-tippers blight our towns, villages and beautiful landscapes.
“We all have a responsibility to get rid of our waste legally and safely, and Fly-tipping Action Wales is committed to working with local authorities and other partners to make sure that a strong sense of pride remains in our communities.”
Cllr Rob Gough, cabinet member of public protection for Caerphilly County Borough Council said: “Although the vast majority of our residents take their environmental responsibilities seriously, there still remains a very small minority who do not.
“Our team of Enforcement Officers work tirelessly to tackle environmental issues including fly-tipping in our county borough, and I want to send out a clear message to those who do feel it is acceptable to fly tip that their behaviour will not be tolerated.”
