25 — Waste Water

  1. Wastewater from the kitchen sink and bathroom shower drains through a separate wastewater pipe and underground drainage at a protected or unprotected outlet into a planted area in the garden. Wastewater from a toilet drains through another pipe into an underground septic tank. 
  2. The kitchen sink and bathroom water outlet have a strainer or drain sieve which has two main functions: Firstly, the strainer should keep off small particles of food and body hairs from floating into the drain pipe to avoid blockage of the wastewater flow in the U-shaped trap pipe (below a kitchen sink, or in the underground of a bathroom strainer). Secondly, the strainer should keep off unwanted animals that might enter the wastewater outlet and underground wastewater pipe. 
  3. Therefore, the strainer should never be removed, except during cleaning. Cleaning, mainly the removal of settled particles and hairs on the sieve or in the strainer, should be done by the tenant regularly, e.g. every two weeks. 
  4. It is not permissible to remove the strainer to thereby convey larger particles and hairs through the drainage. This would inevitably block the wastewater outlet in the garden sooner or later.
  5. Tenants are requested to check the wastewater outlets from time to time. There are unprotected wastewater outlets, i.e., the blue PVC wastewater pipe ends without a strainer, and there are protected wastewater outlets with a strainer. Here is an overview of the wastewater outlets for each house:
    Plumeria Home: 1 protected outlet east of Plumeria Bungalow, and 1 unprotected outlet northwest of Khilek Pavilion.
    Dillenia Home: 1 protected outlet north of Dillenia Bungalow, and 1 protected outlet northwest of Chom Doi Pavilion.
    Tai Saeng Chan Pavilion (Moonlight Pavilion): 1 protected outlet southeast of the Pavilion, and 1 protected outlet west of the bathroom of the Pavilion.
    Lychee Lodge: 3 unprotected outlets southeast of the bathroom of the Lodge, and 1 unprotected outlet southeast of the laundry hut of the Lodge.
    Clerodendrum Chalet South: 2 unprotected outlets south of the kitchen of the Chalet, and 2 unprotected outlets south of the laundry of the Chalet.
    Clerodendrum Chalet West: 1 unprotected outlet west of the Chalet.
  6. We are happy to show tenants the exact location of the wastewater outlets. The outlets protected with a strainer should be checked if dirt has accumulated, thus cannot pass the strainer and increasingly impedes the wastewater flow over time. Both protected and unprotected outlets should be regularly checked if they stay free from plants that may let their roots grow to the outlet and into the PVC pipe
