Disposing sewerage waste to any body of water is a violation of Section 27 (a) of Republic Act (RA) 9275, otherwise known as the “Philippine Clean Water Act of 2004”: “Prohibited Acts. – The following acts are hereby prohibited: a) Discharging, depositing or causing to be deposited material of any kind directly or indirectly into the water bodies or along the margins of any surface water, where, the same shall be liable to be washed into such surface water, either by tide action or by storm, floods or otherwise, which could cause water pollution or impede natural flow in the water body”; Even if your neighbor will dig a pit where he will dump the sewerage waste, the same will still constitute a violation of RA 9275 specifically Section 27 (b) thereof which states: “b) Discharging, injecting or allowing to seep into the soil or sub-soil any substance in any form that would pollute groundwater. In the case of geothermal projects, and subject to the approval of the Department, regulated discharge for short-term activities (e.g. well testing, flushing, commissioning, venting) and deep re-injection of geothermal liquids may be allowed: Provided, That safety measures are adopted to prevent the contamination of the groundwater.”
