A report published on 12 November said that no wastewater treatment plant in Gaza was operational as weekend flooding compounded a sanitation crisis created by the war. In Gaza City, rainwater mixed with sewage threatened to overflow the Sheikh Radwan stormwater basin, where only two of six pumps remained working; the reported headline figure is six pumps, with four unavailable. OCHA
The outage matters to plant managers because the immediate need is not simply additional treatment capacity: the source identifies missing vacuum trucks, mobile dewatering pumps, engine oil, hoses and heavy machinery needed to restore drainage and sanitation operations. OCHA
Key takeaways
- No wastewater treatment plant in Gaza was reported as operational. OCHA
- Rainwater mixed with sewage threatened to overflow the Sheikh Radwan stormwater basin in Gaza City. OCHA
- Only two of six pumps were working at the stormwater basin. OCHA
- UNICEF had been seeking Israeli approval for more than a year to bring in equipment needed to repair the facility. OCHA
- Humanitarians cleared sewage and stormwater in more than 50 locations during the preceding week. OCHA
What happened
The report said weekend flooding was compounding a sanitation crisis created by the war, leaving all wastewater treatment plants in Gaza inoperable. The immediate infrastructure risk centered on the Sheikh Radwan stormwater basin, where rainwater mixed with sewage and threatened to overflow. OCHA
Two of the basin's six pumps were still working. UNICEF said it had sought approval from Israeli authorities for more than a year to bring in the equipment needed to repair the facility. OCHA
The report added that humanitarian funding and Israeli approvals were urgently needed to bring in sufficient supplies and machinery, including vacuum trucks, mobile dewatering pumps, engine oil, hoses and heavy machinery. UNICEF also reported clearing sewage and stormwater in more than 50 locations over the preceding week. OCHA
Humanitarian partners identified 356 flood-risk sites requiring heavy machinery for improvements, drainage, levelling and road strengthening, and said restrictions on humanitarian items needed for repairs and more resilient shelter had to be lifted and their entry expedited. OCHA
Specification read
The source did not report wastewater flow in MLD or m³/day, a population-equivalent loading, or BOD and COD concentrations, so the plant scale and treatment-performance requirements cannot be calculated from the available information. OCHA
For a municipal wastewater plant serving dense urban districts, the treatment train would normally be evaluated from screening through primary settling, biological treatment and tertiary or disinfection, with flood-resilient pumping, storage and sludge handling considered alongside it. Here, the reported failure is at the collection, pumping and emergency-response stage: treatment plants are not operational, stormwater and sewage are mixing, and the Sheikh Radwan basin retains only two of six pumps. OCHA
That distinction matters in enquiries: a buyer may need to separate long-term treatment capacity from immediate flood-response equipment, including vacuum trucks, mobile dewatering pumps, hoses, power support and heavy machinery. The source named these items but did not provide their duty points, flow ratings, power requirements or delivery schedules. OCHA
If your plant looks like a dense urban wastewater system with a combined or flood-exposed drainage network, continuous treatment compliance pressure, no operational treatment capacity and a stormwater basin needing major pumping recovery, this event points first to an operational-resilience and emergency-dewatering specification rather than a stand-alone biological-process selection. No design flow or influent quality was reported, so neither can be specified from this coverage. OCHA
Related buyer guidance for domestic sewage treatment in Shah Alam domestic sewage treatment and Ipoh domestic sewage treatment provides a separate reference for scoping treatment requirements; neither reference establishes the capacity of the Gaza system described in the report.
FAQ
What treatment capacity is required for the affected wastewater system?
The source did not report flow in MLD or m³/day, population equivalent, BOD or COD, so no defensible treatment capacity can be calculated. A scoping exercise would first require those wastewater and storm-response inputs, plus the available treatment footprint and required compliance performance. The reported problem includes non-operational treatment plants and a flooded basin with only two of six pumps working. OCHA
Which equipment is needed first for emergency response?
The source identifies vacuum trucks, mobile dewatering pumps, engine oil, hoses and heavy machinery as urgently needed. It does not specify pump capacity, hose length, truck volume, operating duration or power ratings, so suppliers would need site data before proposing a compliant package. OCHA
What will the treatment package cost and how long will delivery take?
No equipment cost, procurement value or delivery lead time for the wastewater works was reported, so a reliable cost or schedule cannot be stated. The stated dependency is urgent humanitarian funding and Israeli approval for the necessary supplies and machinery, with restrictions on humanitarian items needing to be lifted and entry expedited. OCHA
Should a supplier be selected for treatment capacity or flood resilience?
The event points to both, but at different stages. The immediate need is collection, pumping and emergency-dewatering resilience at the Sheikh Radwan basin; the longer-term treatment train must cover screening, primary treatment, biological treatment and appropriate tertiary or disinfection once flow and quality data are established. The source did not report the flow, pollutant concentrations, footprint or treatment-class criteria needed for supplier selection. OCHA
