Water is provided and maintained by each city. The city negotiates water rates for blocks of water from the Weber Basin Water Conservancy District. Each has secured water for existing homes and businesses with the ability to obtain more water in the future as demand requires it. The city is responsible for treatment and delivery of the water. Rates do vary by city.
Sewer is provided by either North Davis Sewer District or South Davis Sewer District. Depending on your location, one or the other will provide services. Both systems have excess capacity to grow into the future before an upgrade is needed.
Refuse is negotiated through the city with numerous providers so the costs can be kept low. The city sends one bill out with all services broken down. To give an example of water, sewer, and refuse fees in Davis County, the fees for the most populous city in Davis County, Layton, will be given - (in Layton, fees are charged every 2 months, so the figures are every 2 month fees): Water - $21.10, Sewer - $27.90, Garbage - $20.20, Storm Drainage - $9.20. This makes a monthly bill around $39.20 for all services.
