These limits are reached at different points in time, usually with end <strong>of</strong> service life (driven by<br />
customer complaints) reached be<strong>for</strong>e physical or economic end <strong>of</strong> life is achieved. However, most<br />
condition assessment activities are focused on the determination <strong>of</strong> the end <strong>of</strong> the physical life <strong>of</strong> the<br />
asset, while it is the end <strong>of</strong> service life or economic life that drives reinvestment.<br />
One <strong>of</strong> the key decisions a utility manager has to make is when to rehabilitate an asset from an<br />
economic and service life standpoint. Answering this question is beyond the scope <strong>of</strong> this report, but<br />
is vital to the asset management <strong>of</strong> a sewer <strong>for</strong>ce main system. This topic will be addressed in a later<br />
research report, which is devoted to decision-making support systems <strong>for</strong> replacement versus<br />
rehabilitation.<br />

Demonstration/Verification <strong>of</strong> Pressure System <strong>Rehabilitation</strong><br />
The need at this stage is to demonstrate or verify elements <strong>of</strong> pressure system rehabilitation. Tables<br />
7-1 and 8-1 set out the needs and the specific elements to verify. All <strong>of</strong> these are contributors to the<br />
development <strong>of</strong> an integrated asset management program <strong>for</strong> the <strong>for</strong>ce main element <strong>of</strong> wastewater<br />
systems. Their verification will enable methodologies and protocols <strong>for</strong> comprehensive system<br />
rehabilitation programs to be developed that are robust, efficient, and cost-effective. A combination<br />
<strong>of</strong> demonstration projects to verify capabilities and closing gaps in data and knowledge is essential to<br />
support development <strong>of</strong> the necessary tools <strong>for</strong> <strong>for</strong>ce main rehabilitation programs. Programs that<br />
allow an owner to reasonably predict the remaining life <strong>of</strong> a <strong>for</strong>ce main that has been renewed with a<br />
liner is paramount.<br />
