Paragraph 4 Small discharges of sewage effluent: England
For the purpose of paragraph 8(a)(i) of Schedule 2, the description is a discharge from a septic tank or sewage treatment plant of 2 cubic metres per day or less of sewage effluent that results in the input of pollutants to groundwater.
For the purpose of paragraph 8(a)(ii) of that Schedule, the conditions in relation to a groundwater activity of that description are that an operator of the septic tank or sewage treatment plant ensures that—
all works and equipment used for the treatment of sewage effluent and its discharge comply with the requirements specified in the document entitled “General binding rules for small sewage discharges (SSDs) with effect from January 2015” issued by the Agency and the Department for Environment, Food and Rural Affairs and published on 27th October 2014 and updated on 21st January 2015 in relation to—
design and manufacturing standards,
construction, installation and operation specifications,
siting and installation of infiltration systems, and
the capacity of the works and equipment;
in the case of a discharge which takes place for the first time on or after 1st January 2015, the discharge could not reasonably be made to the foul sewer;
the discharge does not contain trade effluent;
the discharge does not result in an input of pollutants to groundwater—
within 50 metres of a point at which water is abstracted for domestic or food production purposes from underground strata, or
within a zone defined by a 50-day travel time for groundwater to reach a groundwater abstraction point that is used to supply water for domestic or food production purposes;
all works and equipment used for the treatment of sewage effluent and its discharge are maintained in accordance with the manufacturer’s specification;
all works and equipment for the treatment of sewage effluent and its discharge are appropriately decommissioned when the exempt facility ceases to be in operation so that there is no risk of pollutants entering groundwater;
before the land or part of the land on which the septic tank or sewage treatment plant is situated or being used is sold, an owner of the land or part of the land gives to the purchaser a written notice—
stating that an exempt groundwater activity is being carried on on the land, and
containing a description of the exempt facility.
For the purposes of this paragraph, an operator is a person who has control over the operation of the septic tank or sewage treatment plant by reason of—
being an owner of the land on which the septic tank or sewage treatment plant is situated or being used, or
having entered into a written agreement with the owner of the land on which the septic tank or sewage treatment plant is situated or being used to be responsible for the maintenance of the septic tank or sewage treatment plant.
