The influence of the environment leads to corrosion damage to pipelines. To prevent these damages, it is necessary to establish an anticorrosion protection on time and in appropriate places. The purpose of the work is to protect underground pipelines in water supply systems at livestock complexes and thereby prolong the resource of their use by determining the capacity and number of cathodic stations and their protective zone. The theoretical and experimental component of research on the active protection of pipelines on livestock breeding complexes was carried out on the basis of the fundamental oyster of cathodic stations and the calculation of the electrochemical protection of underground structures with the determination of the capacity, the number of cathodic stations and their protective zone on the territory of the livestock complex in the experimental farm of Vorzel in the Kiev region. It is established that for a total length of 1,722 m, one cathode station with a capacity of 600 W is sufficient. That should ensure an increase in the economic efficiency of the water supply system by 10–15 % and prolong the period of its operation.
