 System Rehabilitation & Upgrade

Markcillio distribution team have been involved in a number of distribution rehabilitation projects in different states, including evaluation of existing system, preparation of Rehabilitation Master-Plans and training on rehabilitation techniques.
Distribution networks are generally large in volume, as it spreads all over the country/area to feed its customers. Since, these networks are usually subject to huge expansions, the utilities are normally facing difficulties on carrying out routine and planned maintenance activities and this results a poor voltage and reliability levels to the end consumers and also fast deterioration of the network. In order to overcome this situation, most of the utilities are going for a complete rehabilitation / refurbishment for its distribution networks, mainly to improve voltage and reliability levels of the system.
