Chronic Operational Disruptions in Monterey Park’s Pneumatic Waste System


Monterey Park Condominium, a 280-unit residential development in West Coast Rise, operates on a Mobile Pneumatic Waste Conveyance System (MPWCS).
Generating about 1.12 tons of refuse daily, the estate faced recurring system blockages due to limited access points. Greenwave Solutions was engaged to retrofit the system for smoother performance and long-term serviceability.
Implementation Approach
Greenwave’s engineering team cleared existing debris blockages in the MPWCS main pipeline. Recognising that high-speed pneumatic suction (30–60 mph) can fracture pipes and induce clogs, the team installed three new reinforced maintenance chambers with sealed access hatches at key pipeline nodes.
These chambers were integrated into the vacuum pipe network so that standard vacuum-truck hoses can reach and clean any segment.
The upgrades enabled faster blockage removal, improved accessibility for vacuum truck servicing, and ensured continuous system operation with minimal disruption to residents.


The upgrade was executed with precision trenching and pipework tied into the existing MPWCS loop. After identifying blockage locations, crews excavated and cut into the main vacuum pipe at optimal points. Prefabricated reinforced chambers were inserted and connected in line.
All tie-ins used compatible piping fittings and sealing to maintain vacuum integrity. Works were phased to keep the system running, ensuring that the new chambers met pneumatic-system design standards and did not disrupt resident waste disposal.
“Strategically placed maintenance chambers ensure quick access for clearing obstructions, significantly improving the MPWCS reliability. Future blockages can now be cleared swiftly without disrupting operations.”
