Scheduled desludging for thousands of septic tanks, sewer and manhole jobs, network pump station visits and confined space competence, with proof of every visit.
For Malaysian sewerage contractors, desludging permit holders and the teams behind the public sewerage network, FieldEx joins field service management with a CMMS (maintenance management system). It runs scheduled desludging for large lists of premises, sewer and manhole jobs and network pump station visits, and checks that every crew entering a manhole is certified.
Since March 2021, septic tank owners have had to desludge on a fixed cycle, and each visit is booked for the date in the operator's notice. FieldEx turns those schedules, the network jobs and the crews' certificates into work you can prove. Book a demo with one of your work packages.
The Water Services Industry (Desludging Services) Regulations 2021 came into force on 30 March 2021. Indah Water Konsortium (IWK) explains the cycle on its customer pages. Septic tanks within a local authority (PBT) area must be desludged once every 24 months, and those outside a local authority area once every 36 months.
IWK, the national sewerage company, has been sending scheduled desludging notices in stages since July 2021, to 1.3 million septic tank owners in Peninsular Malaysia. An Institution of Engineers Malaysia (IEM) webinar notice puts the scheme at more than 1.35 million septic tanks across the country, except Sabah and Sarawak. SPAN says that failing to comply is an offence under section 65(3) of the Water Services Industry Act 2006, with a fine of up to RM50,000.

Section 50 of the Water Services Industry Act 2006 requires a permit from SPAN for desludging work. The Star reports a state sewerage official's reminder under section 65(1)(c): the septic tank owner must appoint a valid licensee or permit holder to desludge the tank within the prescribed period.
A planning paper from India's Centre for Water and Sanitation (CWAS) describes how Malaysia's model works today: IWK schedules the work, and permit-holding operators carry out the desludging and take the sludge to an IWK facility for treatment.
| Cause (EPA) | Field work that reduces it |
|---|---|
| Fats, oils and grease | Hot-spot cleaning; grease trap programmes |
| Tree roots | Root cutting on a set cycle |
| Inflow and infiltration | CCTV, manhole and lateral inspection |
| Pump failures and power loss | Lift station visits; generator testing |

Enviliance's summary of the 2021 regulations sets out the steps. The service licensee issues a written notice with a date. The owner, management corporation or occupier may reschedule if that date doesn't suit. If they neither give access nor reschedule, the licensee issues a second notice with a new date.
IWK warns that an owner who ignores the second notice commits an offence under section 65(3) of the Act. The Star reported in August 2026 that compliance with scheduled desludging is still low.
| Task | How often |
|---|---|
| Lift station visit and log | Weekly |
| Float cleaning and inspection | 4 times a year |
| Wet well pump-out and cleaning | At least twice a year |

The Department of Occupational Safety and Health's (DOSH) Industry Code of Practice for Safe Working in a Confined Space 2010 is legally binding. Every employer and contractor must assess the risks, and the confined space permit to work overrides any other permit. An Authorised Gas Tester (AGT) tests the air before entry, and continuous monitoring follows.
DOSH's guidance sets the people involved. Entrants and standby persons hold the AESP certificate, and gas testers and entry supervisors hold the AGTES certificate and are registered with DOSH. A permit to work lasts at most eight hours, with an extension of up to four hours if conditions stay the same. A night shift clearing a blocked trunk sewer may therefore need a fresh permit partway through the job.
| Role | Certificate |
|---|---|
| Authorised entrant, standby person | AESP |
| Authorised gas tester, entry supervisor | AGTES (registered with DOSH) |
| Permit issuer | Trained as AGTES |
| Permit to work | Up to 8 hours, plus up to 4 hours |

A Water Environment Partnership in Asia (WEPA) paper on Malaysia's sewerage framework quotes the Water Services Industry Act 2006. No part of any sewerage system may be worked, managed or operated except by, and under the control of, people with the prescribed qualifications and certificates.
The same paper describes IWK's role. It provides scheduled operation and maintenance of public sewage treatment plants, network pump stations and sewers in its service areas, and takes over sewerage systems handed over by developers.
The US Environmental Protection Agency's (EPA) lift station guidance, an international reference here, sets clear cycles. It recommends emptying and cleaning each wet well no less than twice a year, so solids and grease can't accumulate, and cleaning and checking the floats every quarter, since grease jams them.
US state regulators, such as Kansas, expect lift stations to be visited weekly. In Malaysia's heavy rain, pump stations also take storm inflow, so a failed pump or genset quickly becomes an overflow.
Malaysian councils set grease trap conditions in their own licensing, and they vary. US cities offer a common benchmark, the "25% rule". Nashville's FOG policy, for example, requires a grease interceptor to be fully pumped once grease and solids reach 25% of its liquid depth, and at least every 90 days.
Grease is the biggest cause of sewer blockages. EPA reports that grease causes 47% of reported blockages in the US. Malaysian food courts, restaurants and hawker centres discharge large volumes of cooking oil, so the traps upstream of a blockage hot spot are usually the first place to look.
FieldEx records the proof on each visit as the crew works: the premises or asset, the arrival and departure times, watermarked photos and the result. Desludging visits, blockages cleared at night, manhole covers replaced and pumps changed out all carry the same evidence, so the operator can check the work against the contract without sending a supervisor to every site. Under scheduled desludging, as CWAS's planning resource describes it, IWK sets the schedule and licensed permit holders desludge the tanks and deliver the sludge to an IWK facility, so the visit record is what links the premises, the crew and the delivery.
The guide says to test the air before entry, from outside the space, and at all depths, because some gases are heavier than others. Oxygen is tested first, then combustible gases, then toxic gases.
EPA's CMOM guide puts information management at the heart of the programme. You can't prioritise cleaning or rehabilitation without knowing what was done, where and what was found. The Illinois permit asks for the root cause of each overflow to be documented, and for scheduled inspections, testing and cleaning frequencies to be listed.
In practice, every job needs a location, an asset, a date, a crew, a finding and, where relevant, a photo or CCTV report.
Many still run on spreadsheets and chat groups. FieldEx brings premises, tanks, sewers and pump stations onto located records, raises scheduled jobs in bulk and records proof of each visit. See our guide to CMMS software.

No. Jobs and tasks can be downloaded and worked offline, with check-in, check-out and travel synced once the phone reconnects.
Setup, data upload and training are part of the subscription, with no setup fee. Premises, assets and past jobs can be uploaded. FieldEx helps with setup, and training is included.

Once we know your requirements and your data is ready, FieldEx can be implemented in as little as a week with standard features for small businesses. Larger setups and custom work take longer. See FieldEx implementation.
