Code of practice for the design and installation of drainage fields for use in wastewater treatment
This code of practice gives recommendations and guidance on the design and installation of drainage fields and infiltration systems for use in wastewater treatment. It is applicable to systems for handling discharges from domestic and commercial sources from single households upwards. These sources are typically septic tanks and package treatment plants.
General guidance is given on good design and installation practices. Particular requirements are determined by local conditions. The recommendations are supplemented, as required, by specialist advice.
NOTE Attention is drawn to the environmental regulators Pollution Prevention Guidelines Note 4 [2] and building regulations and standards (see Annex B). These require an adequate system of drainage to carry foul water from appliances within the building to one of the following, listed in order of priority:
public sewer
a private sewer communicating with a public sewer
either a package wastewater treatment plant or septic tank, with a discharge to a properly designed drainage field.
Only where it can be demonstrated that the cost and/or practicability of connection to the public foul sewer is not feasible will alternative options, including use of drainage fields, be considered acceptable.
