Environmental Solutions

Treatment, recovery and reuse, designed so the outcome is compliant on paper and viable in operation. We work on wastewater management, faecal sludge and septage handling, organic waste processing, biomethanation and the recovery of resources that would otherwise be disposed of.

How the work runs

The septage and sludge train

Receiving, screening, thickening and drying, sized on what actually arrives. A consent parameter is met by a working process, not by a letter of assurance.

Compliance and viability have to be solved together

A treatment solution that meets discharge norms but costs more to run than the budget allows will not be run for long, and a plant that is switched off is not a compliant plant. We scope environmental works against both the standard that has to be met and the operating cost the body can actually sustain year after year, because the audit that matters is the one three years after commissioning, not the one at handover.

03How an engagement runs

What we are usually asked for

  • Wastewater management and treatment solutions
  • Faecal sludge and septage management (FSSM) and FSTP operation
  • Organic waste processing and composting systems
  • Biomethanation and biogas project support
  • Sludge handling, dewatering and TNPCB compliant disposal
  • Resource recovery and reuse planning
  • Environmental compliance documentation and support

What the department receives

  • Process approach matched to actual volume, load and site constraints
  • Operating cost picture presented alongside the capital estimate
  • Compliance documentation for the relevant authority
  • Recovered streams, treated water, compost, biogas, accounted for
  • Operating support once the system is commissioned

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.

05Questions we are asked
Do you operate faecal sludge treatment plants (FSTPs) as well as design them?
Yes. FSSM is one of the areas where the gap between a commissioned asset and a functioning one is widest, largely because desludging operations, transport and plant operation are often contracted separately and none of them owns the outcome. We can take responsibility across the chain or operate the plant alone, depending on how the ULB has structured it.
How do you handle sludge disposal documentation?
Quantity, transport and destination are recorded for each disposal event and retained as part of monthly reporting, in line with TNPCB requirements. Departments are audited on this and undocumented disposal is a liability regardless of whether the disposal itself was appropriate.
Is a biomethanation plant viable at town panchayat scale?
It depends on the volume and consistency of segregated wet waste available, not on the population figure. Below a reliable daily feedstock threshold, composting is usually the more sustainable answer. We will say so rather than scope a plant that runs at a fraction of design load, underloaded digesters are the most common failed asset in this category.
Where it goes wrong

Four ways environmental solutions quietly fails.

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.

  1. 01

    Treating a process fault as a civil fault

    Adding tank capacity to a plant that is failing on aeration or sludge return spends money without moving the parameter.

  2. 02

    Septage tankered to the nearest convenient point

    Faecal sludge needs a receiving facility and a record. Anything else transfers the problem and the liability.

  3. 03

    Consent renewals prepared in the last month

    The data that supports a renewal has to exist across the year. It cannot be assembled at the deadline.

  4. 04

    Biogas sized on waste that is not available

    A biomethanation unit fed by an unreliable stream sits idle. Feedstock is confirmed before capacity is fixed.

Send us the consent condition you have to meet.

The TNPCB notice, the consent renewal or the sludge problem. We will come back on whether it is a process fix, a civil fix or a capacity fix.
