Efficient Water and Wastewater Facilities

Action 1: Compare the energy use and performance of your facilities with other peer plants using standardized, free tools.

The City of Woodbury provides drinking water from aquifers. The system uses 17 wells to supply the water to residents. The city treats water at the well house with chlorine and fluoride. Woodbury does not operate a waste water plant. Woodbury has a pass through system in which we do not treat the wastewater; it is gravity fed to two different locations for treatment. The two locations are Eagles Point in Cottage Grove and MCES in St. Paul.

Action 2: Plan and budget for motor maintenance and upgrades so as to assure the most energy efficient, durable and appropriate equipment is available when upgrades or break downs occur.

The city performs annual maintenance on all well house facilities and motors. Well motors/pumps are on a 10 year rehabilitation cycle. In rehabilitation, we are implementing Variable Frequency Drives (VFD) for energy efficiency and upgrading our safety controls. Lift station pumps and motors are inspected annually.

Action 3: Establish an on-going budget and program for decreasing inflow and infiltration into sewer lines.

The City of Woodbury has been in the process of pre-televising Road Rehabilitation Projects to inspect sanitary sewer lines of any Inflow/Infiltration issues that may arise. And using the information collected from the televising report to make necessary repairs and set the budget.

Action 7: Create a demand-side management program to reduce demands on water and wastewater systems.

The city also has a tiered conservation rate structure for water rates. Based on the amount of water used, residents pay as low as 88 cents per thousand gallons water, and as much as $4.88 per thousand gallons of water. The tiered system may be viewed at: http://ci.woodbury.mn.us/environment-main/water-restrictions-conservation/water-a-sewer-rates For residents and businesses that sign up for e-bill or an electronic account, they can see their water use compared to other users on their street.
