Change the end to 20 years depending on growth. Fact is that we are only building 75% of the SBRs and are trying to stretch out the life of the plant by doing I&I work. If a UGB expansion comes in to being then we can support that growth with the full upgrade minus the 3rd pond. That expansion will be required to pay for the upgrade by reevaluating SDCs or a special SDC imposed on the expansion. The intent being those already in the UGB are not burdened by a developers expansion of the UGB. Hope that made sense.

Try this one. I received some info from Andy and added the Patrol project.

Take a look at this when you have a chance -
We understand there are questions being asked regarding Wastewater Treatment Plant funding. Basically, the inquiry poses the question of how we were able to reduce new treatment plant costs from $50 million to $22.7 million (actually the cost is 28 million). Is the reduction attributable to money already being spent and design? Design cost is part of this total figure. The answer to this question goes back two-years to the beginning of this process and is generally discussed in the attached City Council briefing link. Many of these questions were asked by the governing body throughout the development and presentation process on two separate occasions.
Wastewater treatment is not just the plant alone. There are many moving parts that must work together in order for the system to work properly. After years of neglecting these moving parts such as the collection system, manholes, headworks, pumps and lift stations, leaking filter repairs, etc., the City began to tackle these items as funding allowed. What we found is that following manhole repair (grouting), clean out caps, and finishing inflow and infiltration work on key projects was that the flow to the plant had been significantly reduced. The treatment plant has gone from treating 2.404 mgd (million gallons per day) during winter months to .82 mgd. And .601 mgd to .56 mgd during summer months. This result is directly attributable to dedication to repair and improvement of the entire system. The Patrol Street project that is commencing this summer is the next priority I & I project that should once again reduce flows to the plant. The link below discusses the work the City has been undertaking for the past two years and will continue to undertake.

We reevaluated treatment plant size needs and developed a plan that constructs a plant to cover community needs over the next 20-years with capacity to add capacity into a treatment facility constructed to accommodate expansion. A person will notice that the reduction in monthly utility rates was significantly adjusted to address the lower cost for construction.
