CitySpring Infrastructure Trust has reported a distribution per unit (DPU) of 0.82 cent for its second quarter ended Sept 30, unchanged from the same period a year ago.

DPU remained constant as its cash earnings dipped 1.9 per cent compared with the same period last year to $13.8 million.

CitySpring's key assets include City Gas, which produces town gas, and SingSpring, which owns a large-scale seawater desalination plant.

CitySpring's manager said that while revenue at City Gas at $98.9 million was comparable to the $98.7 million over the same period last year, SingSpring's revenue fell by $1.4 million to $9.1 million.

It attributed SingSpring's lower turnover to lower fuel costs.

But SingSpring's cash earnings rose to $4 million from $3.6 million due mainly to lower finance cost.
