أنابيب الصرف الصحي هي عنصر أساسي في أي نظام لإدارة مياه الصرف الصحي، حيث تعمل كـ "طرق سريعة" لنقل مياه الصرف الصحي من مصادر متعددة إلى محطة معالجة مركزية. وتستعرض هذه المقالة الدور الحيوي الذي تلعبه هذه الأنابيب في الحفاظ على المياه النظيفة وبيئة صحية.
ما هو أنبوب الصرف الصحي؟
أنبوب الصرف الصحي عبارة عن أنبوب كبير أو نفق مُصمم لجمع مياه الصرف الصحي من العديد من أنابيب الصرف الصحي أو المصارف الصغيرة. فإنه يمنع تدفق مياه الصرف الصحي قبل وصولها إلى المسطحات المائية مثل الأنهار أو البحيرات، مما يمنع التلوث ويحمي الصحة العامة. وتُنفذ هذه الأنابيب عادة بالتوازي مع أنظمة الصرف الصحي المحلية الأصغر، وغالبًا ما تكون على ارتفاع أعلى منها، وتستقبل المياه عن طريق الجاذبية أو محطات الضخ.
