OptiRenewal
OptiRenewal is a software tool built around the OGA optimization technology for the programming and scheduling of pipe renewals programs. It reduces the amount of time to undertake a study while providing a better overall solution.
OptiRenewal is applied to a utility’s hydraulic model, to search for a near-optimal replacement program. For each pipe reviewed, a decision is made as to replace or rehabilitate the pipe. In the case of replacement, the optimal pipe diameter, material, construction technique and proposed year of replacement is selected by OptiRenewal. OptiRenewal identifies the combination of replacement and rehabilitation decisions to minimize the net present value cost of the overall replacement program.
The cost of not replacing pipes, i.e. the risk associated with failure over the given planning period, is included in the optimization process. The solutions must result in a hydraulic network that satisfies customer demands for each staging period, while achieving service levels that meet minimum allowable pressure, maximum allowable velocity, and other specified constraints.
OptiRenewal is available for use in a consulting capacity or can be leased for in-house use by a water utility.
