Sewerage networks, pumping stations and treatment plants only deliver value while they are actually running. We take on day to day operation and maintenance so assets hold their performance parameters instead of degrading quietly between breakdowns.
Operation is the visible half. The log is what a department is audited on, and it is where a developing fault shows up weeks before anyone reports it from the field.
A pump that fails at two in the morning costs far more than the servicing that would have prevented it, in emergency mobilisation, in overflow, in TNPCB exposure, and in the complaints that follow. Our O&M work is built around scheduled preventive maintenance and daily monitoring, so most failures surface as a trend in the log rather than as a call from the field. Every deployment operates on the principle of zero manual entry into sewers and manholes: mechanised cleaning, confined space protocol, and documented disposal.

Scope, documentation and billing are set up to match how each of these bodies actually procures and audits, rather than one format applied to all of them.
Not a list of risks in the abstract. These are the specific things we are called in to correct, and what we check for before quoting anything.
A schedule that exists on paper and is signed monthly, with no completed task record behind it, is not maintenance. It is paperwork.
The commonest reason an STP misses its consent parameters, and the last thing anyone measures. We check MLSS and return sludge first.
Once a line surcharges, the cost is the road, the complaints and the TNPCB exposure, not the jetting.
Attendance, wage and statutory records are what a department is audited on. Crews without them expose the body, not the contractor.
Flow figures, the last inspection note, or simply what the complaints say. We will come back with a view on the cause and what an O and M contract should cover.
