Understanding the vital aspects of the Water (Northern Ireland) Order 1999, specifically the Application For Consent To Discharge Sewage Effluent From A Single Domestic Dwelling (Form WO2), is essential for homeowners, builders, and environmental consultants alike. This form serves as a critical tool in controlling the discharge of sewage effluent, ensuring that it complies with environmental standards to protect public health and the environment. It requires detailed information about the applicant, the site for discharge including grid references or postcodes, and whether a connection to the main sewer system is feasible. If a connection isn't possible, the form diligently asks for specifics about the proposed or existing sewage treatment systems—whether they involve septic tanks or more sophisticated wastewater treatment plants. Notably, the form mandates declarations regarding the system's proximity to dwellings, waterways, and drinking water supplies, alongside certification requirements to ensure compliance with relevant British Standards. For those considering discharging into waterways, additional particulars about the treatment system and its certification are necessary. The form concludes with a declaration segment to affirm the truthfulness of the provided information, underscoring the legal responsibility of the applicant. Completeness and accuracy in filling out this form are paramount, as any false or misleading information could invalidate the consent and possibly lead to prosecution. This underscores the form's role not just in environmental stewardship but also in maintaining the integrity of the application process.
