The hydrant pipes at Kelapa Gading LRT Station play an important role in maintaining station security and safety by providing emergency water supply, especially for fire fighting. However, being made of metal, these pipes are prone to corrosion. Given the important function of the hydrant pipes in maintaining the safety and operation of the station, protection from corrosion is essential to extend their lifespan. To solve the corrosion problem of the 918 metre long hydrant pipe, a system of Cathodic Protection with Sacrificial Anodes (SACP) will be designed and implemented. NACE standard RP-B401 ‘Cathodic Protection Design’ is used as the main guideline in this design. The pipe to be protected is a black steel pipe buried at a depth of 50 metres and coated with primary and secondary. The pipe has a diameter of 8 inches. Zinc anodes were selected as an integral part of the SACP system. Approximately 106 zinc anodes weighing 2.5 kg each were placed on the hydrant pipe at a distance of 8.6 metres from each other to ensure even distribution of protection. Factors such as soil conditions, soil type, moisture content, pipe depth, anode quality, spacing between anodes, pipe quality and condition, and pipe protective coating condition are all important considerations in the design and effectiveness of SACP. With the proper application of SACP, it is expected that the hydrant pipes at Kelapa Gading LRT Station can be protected from corrosion, their lifespan extended to 10 years, and the safety and operation of the station maintaine.
