The Harwich Water Department bills twice per year. Water rates are based upon consumption; inclining block rates have been set to encourage conservation. Thus, the highest users pay a higher rate, so using less water will save you money.
At the current rate of increase of water consumption, Harwich will soon need to develop a new well or wells to meet demand. This process is extremely expensive and time consuming. Conservation measures, such as limitations on outdoor water use and water efficient landscape designs and practices have been shown to result in average water savings of up to fifty percent. Such savings would allow Harwich to sustain itself for the foreseeable future on existing supplies.
Limiting outdoor water use and implementing water efficient landscape designs and practices not only saves you time, energy, and money, but it is also better for the environment.
