Water and Wastewater Treatment Capacity FAQ
FAQ List
How does the lack of water and sewer infrastructure in the Rural Area affect the ability to serve future development?
In December 2022, the Prince William Board of County Supervisors approved a revised Comprehensive Plan that removed public sewer restrictions in the rural area. Prince William Water assessed in an Addendum to the Master Plan, the impact of the change for capacity and infrastructure needs for both water and sewer.
The absence of water and sewer infrastructure in any given part of the County should not be considered an impediment to development under existing “growth pays for growth” policies, which require these infrastructure extensions to be designed, constructed and paid for by development applicants to serve their development.
Has Prince William Water conducted any analysis of the future water needs and availability of water in Prince William County?
Prince William Water annually assesses water needs against the Prince William County Comprehensive Plan, ensuring supply meets demand through at least 2045.
Does new infrastructure to support development and growth lead to subsidy of development by existing customers, taxpayers or the government?
Prince William Water mandates that developers design and finance their project's infrastructure, in harmony with the County's Comprehensive Plan. This policy ensures water and sewer systems can support new developments without compromising service quality.
The Comprehensive Plan Amendment Application for the Prince William Digital Gateway listed the sewage flows generated by the application as being served through the Heritage Hunt Sewage Pump Station. Can the new Heritage Hunt Sewage Pumping Station (SPS) handle these additional sewer flows?
To enable the Little Bull Run Sewer Shed buildout, Heritage Hunt SPS infrastructure upgrades are under construction. The Prince William Digital Gateway is outside the Little Bull Run Wastewater Shed, so wastewater flows from it must be treated by facilities other than the Heritage Hunt SPS.
How much water do data centers use?
Data center water consumption depends on factors such as facility size, cooling type (water intensive or air cooled), and outdoor temperature. Prince William County had 34 data centers in 2023. The average daily water use of a data center building is 13,600 gallons, while the maximum is 102,000. Seasonal weather affects data center water use. Facility water use is lower in winter and higher in summer. Operational data centers in Prince William County consume approximately 1.4% and 6% of Prince William Water's average and maximum daily water demands, respectively.
