Mayor I will be bringing before you and council On December 8, a request to approve 3 necessary and needed studies for the City these are:
Water Distribution Model- This model is compulation of lines sizes, storage tank & pump sizes and existing pressures that exist in the water distribution system collected and analyzed by computer simulations to accurately predict low pressure areas due to inadequate booster staion location and/or line sizes within the system. The model also will ascess fire flows in the system to show areas of low fire flow under varying conditions. The benefit to the City is this becomes an interactive model for us to use in mangaing our distribution system and providing the information needed on extensions of lines and additional storage requirements. It will also give us the ability to better predict water supply needs more accurately.
Sanitary Sewer System Model- This is same concept as the water system model and is a tool that collects existing data including all lift station pump and wet-well sizes and provides us with information on the pumping capacity of the lift stations, determines if lift stations are undersized or maxed out, line sizes and their capacity to add more connections, and will identify areas within the collection system that is contributing infiltration/inflow (I/I) into the system. This is groundwater or runoff water that is getting into the sewer system and we are transporting & treating it. This water does not need to be treated and is costing the city to do so.
Master Drainage Plan- This plan was last developed in 1990 and the plan develops improvements from a City wide view point and how best to manage the overall drainage. It is tied to the Regional Drainage Districts plan and with FEMA and the Corps of Engineers plans. This plan will allow the city to know what types of drinage routes need to be dedicated as the city further develops. It will also be interactive with all of our land use models and Regional Drainage Models.
All 3 of these models will give the City the necessary tools to better plan development and growth and providing the tools we need to better operate the systems in a cost-effective performance based approach. The information will allow staff to be proactive and not reactive to all of these infrastructure needs.
