For the creeks running through the city, General Directorate of State Hydraulic Works carried out rehabilitation works for the sedimentation and floods both in the upper basin and in the tributary rivers flowing into these Creeks. 

As the creeks are located perpendicular to the coast in Giresun Centre, the stormwater collection channels were structured as lines connecting to creeks at the shortest distance. Two sided main stormwater collection pipelines were built only in the streets parallel to the coast. 

There is no project for stormwater collection system. The Municipality has sought to solve the problems locally, through setting up partial lines in various types and diameters whenever needed. There is a 85 km stormwater line available with varying diameters of Ø200 – Ø800, which has been built by the Municipality through partial designs on certain streets, where the stormwater problem is intense. Stormwater lines are composed of concrete and corrugated pipes. In recent 10 years, 60%of concrete pipelines has been changed with corrugated type pipe.
