Description

(Text)
Damaged drains and sewers represent a hazard to the environment, especially the groundwater and soil. Various experiences have been made in rehabilitating damage using renovation processes with locally cured hose liners. Part 3 of the Advisory Guideline DWA-M 144 supplies supplementary harmonised, standardised technical contract conditions (ZTV) for this process. The supplementary technical contract conditions for local curing of hose liners deals with the renovation of drains and sewers outside of buildings, insofar as these drains and sewers are operated as open channel systems.
