Article: An urban runoff facility (SMURFF), the first of its kind in the US, catches and treats 3.5 million US gallons (13,000 m3) of water each week that would otherwise flow into the bay via storm-drains and sells it back to end-users within the city for reuse as gray-water, while bio-swales throughout the city allow rainwater to percolate into and replenish the groundwater supply. The groundwater supply in turn plays an important role in the city's Sustainable Water Master Plan, whereby Santa Monica has set a goal of attaining 100% water independence by 2020. The city has numerous programs designed to promote water conservation among residents, including a rebate of $1.50 per square foot for those who convert water intensive lawns to more local drought-tolerant gardens that require less water.

Now answer this question: Santa Monica plans on water independence by what year?
2020
Artikel: En urban avrinningsanläggning (SMURFF), den första i sitt slag i USA, fångar och behandlar 3,5 miljoner amerikanska liter (13 000 m3) vatten varje vecka som annars skulle strömma in i bukten via stormdrainer och säljer tillbaka det till slutanvändare inom staden för återanvändning som gråvatten, medan bioswales i hela staden tillåter regnvatten att perkolera in i och fylla på grundvattentillförseln. Grundvattnet spelar i sin tur en viktig roll i stadens Sustainable Water Master Plan, där Santa Monica har satt som mål att uppnå 100 % vattenoberoende år 2020. Staden har många program för att främja vattenvård bland invånarna, inklusive en rabatt på $ 1,50 per kvadratfot för dem som konverterar vattenintensiva gräsmattor till mer lokala torka-toleranta trädgårdar som kräver mindre vatten. Svara nu på den här frågan: Vilket år planerar Santa Monica att bli oberoende i vatten?
