Rain Water Harvesting with the Homegrown Rainwater Model
Encouraging Alternative Water Resources for Small Scale and Urban Agriculture
Acadia Tucker, MLWS 2015
Alternative water resources, like rainwater harvesting, are under-utilized yet offer a decentralized approach that can increase the reliability and resiliency of urban water supplies, particularly for urban agricultural production. By exploring alternative approaches to water use and distribution, urban areas can decrease their dependency on large scale water systems and avoid the risks associated with centralized water supplies. Now is the time to start planning for a more unpredictable future in a way that mitigates the adversity linked with these events. The Homegrown Rainwater Model was designed and developed to help small scale growers determine the feasibility of installing a rainwater system at a site. The model design is based on three different steps to help users fully understand the potential system requirements that work best for each individual situation. The model predicts a specific location’s water supply and demand based on easily accessible information such as local precipitation, air temperature and irrigated area.
