With interlocking tiles being installed in several parts of the city, experts from Punjab Agricultural University (PAU) recommend that grass paver tiles should be installed instead to save the depleting groundwater level.


GS Hira, former additional director of research, agriculture, PAU, said the groundwater level of the city had been declining constantly over the past few decades. He said while water was available 10 feet below ground in the 1960s, it was now found at 115 feet.

"By installing interlocking tiles, rain water would not be able to seep through the soil, and groundwater level would reduce further. Grass paver tiles are a good alternative, as they would help preserve the rainwater," Hira said.

He further said if interlocking tiles had to be installed, they should be strong and Calcutta grass should be planted in between the tiles, to make an easy channel for the water to be absorbed by the soil.

Expressing concern that the ground water level was constantly falling, Hira said they had installed grass paver tiles in their area in BRS Nagar to preserve rainwater. Interlocking tiles are installed in many areas across the city, such as BRS Nagar, Gurdev Nagar,
Model Town, Club Road, among others. Consequently, rainwater often goes down the sewerage system instead of seeping into the soil.

JS Dhiman, additional director research, natural resource and plant health management, PAU, also echoed Hira's views, saying that there should be space between tiles so that rainwater could be absorbed by soil.

When contacted, Tanveer Singh Dhaliwal, councillor of Ward Number 59, said there was no provision of gardner from the government. So if grass paver tiles were installed, there would no one to maintain the grass.
