Making a long-term replacement plan based on a “MIAD” database

The replacement plan presents the expected replacement needs of water utilities, based on the MIAD database consecutively in 50 year horizon level.

Within the design work we make a long-term replacement plan and replacement needs forecast, processing by existing and produced data, or additional technical data.

The complete, long-term replacement plans may serve as the basis for the replacement part of rolling replacement plans, because they prepare replacement needs the same structure, divided into disciplines and water utility systems, for the entire water and wastewater service area. This correctly fits the 292/2014 (XI.26) Hungarian Government Regulation Chapter VIII / A., amending Government Decree 58/2013. (II.27.).

The asset inventory serves as starting base in any case the Integrated Multi-attribute Water Infrastructure Asset Evaluation.

For the actual scheduling of expected, planned replacements and effective support of the rolling replacement plan, further analysis and additional analytical work required. Based on this result, the rational technical and professional aspects considering the replacement peaks can be prolonged, timing can be optimized.

In recent years we made these long-term replacement plans mainly for CBA calculations, found in EU investments related feasibility studies. During these asset evaluations we organize the existing and newly established asset items in a homogenous database, and then we analyzed the replacements together, that are required each year, in a 50 years long time interval. The long-term replacement plan for the Hungarian State-owned water utilities belongs to our featured references.
