District Systems

The following systems are being considered and currently under review as part of district infrastructure design: GROW Sustainable Infrastructure.

District Energy

District Heating and Cooling
SVED plans to develop a central plant to generate district-wide heating and cooling to the Sun Valley neighborhood. The plant will hold a heat producing system like a natural gas boiler as well as a cooling system, like an electric chiller. A distribution piping network will then supply the plant-generated heating and cooling to buildings throughout the district. Transfer stations at each building will allow district heating and cooling to reach individual building systems. Plans involve one to two facilities to house the central plant systems which have the potential to reduce annual energy use by 20%. Infrastructure may include:

  • Central plant(s) (5,000 SF)
  • Ground source heat pump well fields (2-3 acres)
  • Distribution system (piping network)
  • Building energy transfer stations (building scale

Renewable Energy (Solar Photovoltaic)
Based on future development plans, solar PV panels installed throughout Sun Valley both roof and ground mount would generate over 5 MW of energy annually. This clean, renewable source of energy would supply approximately 30% of Sun Valley's electricity use annually. Solar PV Installation (anticipated):

  • Roof-mount Panels - 228,750 SF
  • Ground-mount Panels - 87,120 SF
  • Total SF - 315,870 SF : 5.31 MW/year

District Water

Sun Valley will have a single district water system to collect, treat and reuse wastewater as a non-potable water throughout the district to flush toilets, supply irrigation, and provide water for cooling. This system has the potential to reduce water use by 40% annually. Infrastructure may include:

  • Wastewater collection system
  • Wastewater treatment system
    - A "living machine to provide wastewater treatment because of the natural treatment processes utilized are effective, energy efficient and provide a visual learning opportunity for the community.
  • Reclaimed water distribution system
  • On-site drywells for discharge to the South Platte River (to discharge unused reclaimed water)

* In addition, new buildings will have a potable water system and a non-potable water system.

District Stormwater
The following infrastructure concepts are being considered for stormwater management:

Grey Infrastructure: utilizes subsurface collection, treatment, storage and disposal to manage stormwater runoff.

Green Infrastructure: utilizes at-grade natural stormwater facilities to manage, treat and dispose of stormwater runoff. Pipes are also used to convey stormwater but used sparingly.

Centralized Management: collect and conveys stormwater runoff to a large, central facility for treatment and disposal.

Decentralized Management: manages stormwater runoff with small, distributed facilities.
