Worked Solution & Example Answer:The typical layout of an on-site wastewater treatment system suitable for a single house is shown in the accompanying drawing - Leaving Cert Construction Studies - Question 4 - 2012
Step 1
Discuss in detail three reasons why a proposed site for a dwelling house may be unsuitable for a conventional septic tank wastewater treatment system.
Answer
-
Site Size: The proposed site must be large enough to accommodate the septic tank and percolation field. A small site may not provide sufficient space for effective treatment.
-
Drainage Conditions: If the site has insufficient drainage due to dense soils or high water tables, it can lead to system failure and contamination. Sites with heavy clay or flooding potential are unsuitable.
-
Proximity to Contamination Sources: Locations near bodies of water, such as lakes or rivers, pose a risk of effluent contaminating these water sources. Additionally, proximity to other wastewater sources must be considered to prevent cross-contamination.
