The division has established a very effective annual preventative maintenance program on their pumping stations that has reduced the amount of pump failures and replacement cost. This program includes but is not limited to oil coolant replacement, in-house bearing, seal, impeller, wear ring and volute replacement along with scheduled inspections.
The division provides in-house installation of CIPP sectional liners in the gravity mains that reduces the amount of open cut repairs in the roadways therefore reducing road closers, material cost and labor cost.
A monthly cleaning program has been established to reduce the amount of FOG (Fats, Oils and Greases) and debris build up inside the pumping stations and mainlines in areas that are prone to these conditions.
In 2008 the City had an extensive Inflow and Infiltration (I&I) study conducted by Carollo Engineering and will be following the recommendation provided to them to reduce the amount of I&I entering the sanitary sewer system. These recommendations are set up on a 10 year corrective action plan with annual goals for the City to meet.
