One of the greatest challenges facing homeless dogs and cats is finding a reliable source of drinking water. There are few natural sources of water available in the heavily human-developed environment which many animals share with us. While there is certainly a large number of individuals and organizations in society who selflessly give their time and effort towards providing homeless animals with basic needs, it is unreasonable to expect that they will be able to devote each and every day to doing this.

流浪犬貓面臨的最大挑戰之一，就是找到可飲用的水源。這些動物與人們生活在同一個環境中，不過因為人類高度的發展，導致動物能飲用的天然水源其實少之又少。雖然社會上有許多組織和善心人士無私地奉獻自己的時間及心力幫助流浪動物，盡可能地滿足牠們的基本需求，但我們不該只期望他人。

Another of our mini-goals for this semester was to design and construct a water dispenser that can filter and automatically dispense water continuously for some days. Strategically placing these water dispensers in high traffic areas where homeless animals frequently appear may take care of a serious need, and also lessen the workload of volunteers and helpers.

本學期的目標之一是設計和建造一個自動飲水器。它將會有濾水及可以持續幾天的自動補水功能。將這些飲水器戰放置在流浪動物經常出沒的區域，不但可以滿足動物的需求，也可以減輕義工和善心人士的工作量。

This is an ongoing process which has been delayed by the switch to online classes, although the students have already started to become familiarized with some of the scientific concepts behind this task. They have studied water consistency and a simple testing process which can show the purity of a water source, and we have learned the physics of gravity and air pressure which allows our designs to work. The final product will take further development. At this time, the students have a working prototype which will serve as a starting blueprint for the future.
