Drainage

Smart, Sustainable Solutions Backed by Experience.

KGB Infrastructure delivers expert drainage design services tailored to meet the demands of modern developments. We begin with detailed inspections and assessments of existing drainage networks to evaluate their condition and capacity, ensuring every design is built on solid foundations.

We specialise in both private and adoptable foul and surface water drainage systems, designed in line with current legislation, planning policies, and technical approvals—including Section 104/106 agreements and Building Over or Close to Public Sewer consents.
