The septic system includes a septic tank and leach field. Most of the homes in west Greenwich don't connect to the city sewage system, instead, the wastewater is processed by the land. The wastewater firstly flows into the septic tank, where the microbes took time to digest the nutrients in the water. A Septic tank is a thick cement tank that can hold lots of water and keep the water from freezing during the winter. It has pipes connecting to the bleaching field. The microbes processed water then flow to the leach field via a filter. The leach field has many Fern growing there, the plants' root system further absorb the remaining nutrients in the water.
Needless to say, the microbes in the septic tank and the plants on the leach field are important to the process. If you have to dig in the leach field, be careful not to break the pipes buried underneath, there is an irrigation system to distribute the wastewaters across the leach field.
The septic tank is located outside the bathroom on the east, the opening is covered by a round-shaped cap and a square-shaped cap. The leach field is located in the south-east corner of the land.
It is important to know that the cleansing capacity for the plants is not limitless. If you send too much water into the leach field or use lots of chemicals, the plants won't be able to get rid of all of them. The dissolved chemical will remain in the water, sinking down into the underground water. After the filters (soil, full house filter, staged kitchen filter) get rid of some of them, the remaining cleansing work has to be taken care of by your own liver. So be nice to the environment, it's for your own health.
Small tips:
- Don't wash the organic kitchen waste into the drain and burden the septic system, turn them into garden compost instead.
- Use environment-friendly chemicals for dish-washing and laundry.
