Raspberry Falls and Selma Estates New Water Treatment Facility

Loudoun Water is proceeding with the design and construction of a single water treatment plant to serve all of the water needs of both the Raspberry Falls and Selma Estates communities. The plant will be located in Selma Estates. This site is most suitable for water distribution since it is located at a higher elevation than Raspberry Falls and gravity can be utilized for reliability and cost effectiveness.

The plant will use membrane filtration for pathogen/bacteria removal. The membrane treatment facility will be comprised of several components, including pumps, strainers and storage tanks, in addition to the membrane filter units. 

The plant will be sized based on the maximum daily usage observed over the past six years, which is 900 gallons per day per connection. 

The project is currently in design and will be bid ready at the end of 2015. Construction is estimated to begin in 2016.  The treatment plant is planned to be operational in 2017.

Loudoun Water will fund the capital costs of the new water treatment system through its general fund. The general fund will be replenished over time through user rates received from all Loudoun Water customers.

Raspberry Falls Current Treatment System

Water is supplied to Raspberry Falls by two community wells, and wastewater is collected and treated to a high degree at the wastewater treatment plant (WWTP). Most organic material and nutrients are removed through biological treatment before being disinfected and discharged to an unnamed tributary of Limestone Branch.

12/16/2015: Loudoun Water Adopts New User Rates Effective April 2016
The Loudoun Water Board of Directors adopted new user rates for the next three years at their meeting on December 10, 2015.  The user rates, which will apply to all existing and future metered customers, were unanimously approved and take effect April 1, 2016.

The result of the Board action is a 3% increase to the existing Central System rates in 2016 with an additional 3% increase in 2017 and 2018. Those increases are consistent with the previous three years and keep Loudoun Water user rates very competitive within the region.

The Board also approved a uniform rate structure for all customers. Currently, Loudoun Water has separate user rates for Central System customers and Community System customers. The decision to move forward with a uniform rate was based in part on the results of a rate study completed in 2015. Evolving circumstances, including plans to connect two existing Community Systems to the Central System, make it feasible for all customers to be under one uniform rate schedule without a significant impact on planned rate increases.

Loudoun Water continues construction on the Potomac Water Supply Program, a major initiative to develop a new sustainable water supply in Loudoun County. Planning efforts, both in terms of securing a sustainable water future, along with long-term financial viability are the primary drivers for the Authority to adopt and maintain competitive rates.
