2005 Solar Decathlon Rules and Regulations

10.7.7. Watering Vegetation
Water from the house water system may be used to water any potted vegetation associated with the house.
10.7.8. Wastewater
All drains for appliances or sinks need to be routed back to a 350-gallon (1325 liters) minimum capacity drum to ensure that wastewater is
not dispersed onto the National Mall turf or into storm drains. The wastewater drum must have a minimum 4-in. (10.2 cm) diameter cap,
no higher than 6 ft (1.83 m) from ground level, that is easily accessible, on the gravel-road side of the house. All wastewater and water
used in Contest 7: Hot Water must be stored in the wastewater drum. During the Event, dumping of water on the lot will not be permitted,
according to NPS rules. Any dumping of water will incur a point penalty. All substances used in combination with water to clean the
house, dishes, utensils, etc., must be nontoxic and preferably biodegradable. Teams could incur a point penalty for any toxic substances
that are found in the wastewater drum. Teams will be required to provide the drum and support this drum so that it does not damage the
National Mall turf. Teams are not required to place the wastewater drum within the 800-ft 2 (74.3 m 2 ) footprint, but the drum must be
located within the solar envelope.
10.7.9. Wastewater and Thermal Storage Water Removal
During Disassembly, all wastewater and thermal storage water shall be removed by a wastewater truck in a manner similar to the way in
which the water was delivered. The wastewater truck will be equipped with a pump to aid in removal. Two wastewater trucks will begin at
the northwest and southeast corners of the Solar Village and proceed clockwise in emptying wastewater and thermal storage tanks.
10.8 Electric Car
10.8.1. Pushing and Pulling
In no case shall regenerative braking be engaged while pushing or pulling the car. Except for the following situations, the team’s car may
not be pushed or pulled during Contest hours:
• Emergency: In an emergency or breakdown situation, the car must be removed from the road. In this circumstance, the car may be
towed back to Headquarters for inspection and repair.
• Accidents and Re-inspection: All accidents involving the car or support vehicles must be reported immediately to Solar Decathlon
Headquarters. In case of an accident involving personal injury or property damage (or both), notification of the appropriate
emergency medical services and public safety officials shall take priority. Notification to the school’s insurer shall be made as
soon as practicable. If a car is involved in an accident, it must be re-inspected by an Inspector before reentering the Contest. The
Inspector may require that repairs be made before the team can resume the Contest.
