What preventive maintenance actually covers
Instead of waiting for an emergency choke to disrupt operations or cause costly property damage, a planned preventive maintenance program establishes cyclical inspection and scheduled cleaning intervals across all critical drainage assets.
A comprehensive program integrates grease trap pump-outs, cyclical hydro jetting of kitchen lines, chamber silt clearing, CCTV baseline condition surveys, and sump pump checks tailored to the specific property type.
Key Capabilities & Standards
- Eliminates unexpected business shutdowns, customer complaints, and costly emergency repairs
- Scheduled grease trap pump-outs, kitchen stack jetting, and external drain flushing
- Baseline CCTV camera surveys to track pipe deterioration and joint integrity
- Customized maintenance intervals based on property usage, load, and age
Eight-stage professional maintenance workflow
Stage 1: Asset inventory. Map critical pipe runs, inspection chambers, manholes, floor traps, grease interceptors, sumps, and pumps, noting access hours and problem history.
Stage 2: Risk prioritisation. Rank assets by business impact, grease/silt loading, usage volume, pipe material age, and proximity to sensitive dining or living areas.
Stage 3: Baseline inspection. Review past maintenance records and complaints; visually inspect chambers and traps, conducting baseline CCTV surveys to determine pipe conditions.
Stage 4: Create maintenance schedule. Specify inspection intervals, trap pump-outs, cyclical jetting dates, and formal survey timelines aligned with site requirements.
Key Capabilities & Standards
- Detailed asset register mapping all internal and external drainage fixtures
- Risk-based asset ranking focusing attention on high-load kitchen stacks and sumps
- Baseline CCTV footage documenting initial structural and hydraulic condition
- Customized maintenance calendar with clear visit frequencies and task scopes
Scheduled cleaning, verification & documentation
Stage 5: Perform scheduled cleaning. Execute planned cleaning using calibrated methods, suitable access, containment, and site-specific safety controls.
Stage 6: Verify performance & condition. Confirm normal hydraulic flow, recording any persistent standing water, joint offsets, or grease re-accumulation rates.
Stage 7: Record evidence & logs. Maintain formal records with dates, asset IDs, cleaning methods, findings, waste disposal receipts, and recommended follow-up.
Stage 8: Refine the maintenance plan. Optimize visit frequencies based on observed loading; escalate structurally damaged pipes to repair rather than repeated cleaning.
Key Capabilities & Standards
- Calibrated jetting and cleaning tailored to specific pipe materials and conditions
- Rigorous hydraulic flow checks verify unrestricted gravitational transit
- Detailed maintenance logs and electronic waste receipts for statutory compliance
- Continual schedule optimization based on empirical asset performance
Singapore standards for food premises & commercial sites
For food establishments and commercial buildings, PUB publishes recommended maintenance intervals: grease trap cleaning at least every two weeks; private sewerage cleaning and flushing at least once every six months; CCTV inspection at least once every five years; and visual inspection of chambers at least once every five years.
Our maintenance contracts incorporate these official recommendations, ensuring complete compliance with PUB and NEA regulatory audit requirements.
Key Capabilities & Standards
- Fortnightly grease trap servicing complying with PUB and NEA food shop standards
- Bi-annual private sewer stack cleaning and flushing to prevent grease buildup
- 5-year cyclical CCTV pipeline condition surveys for long-term asset tracking
- Complete audit trail protecting facility managers from regulatory non-compliance

Frequently asked questions
How often should a property maintain its drainage system?
There is no single frequency for every property. Water usage volume, grease/silt loading, historical choke frequency, pipe condition, and PUB/NEA guidelines determine the optimal plan. Commercial kitchens often require fortnightly grease servicing, while residential estates benefit from bi-annual flushing.
Does preventive jetting guarantee no future blockages?
Regular jetting drastically reduces accumulated grease, sludge, and scale—preventing the vast majority of chokes. However, it cannot prevent sudden blockages caused by foreign objects improperly flushed down toilets or structural damage caused by ground movement.
Do we need CCTV camera inspections on every visit?
No. CCTV is typically deployed for baseline audits, when investigating chronic recurring chokes, or on a 3-to-5 year cyclical basis to evaluate structural pipeline integrity.
