Water, Wastewater & Solid Waste Management

Treatment systems designed for the real load — sewage, solid waste, pool and process water.

Most treatment failures are not design failures — they are sizing and operating failures. A system that was correctly specified will still breach limits if it is run outside its design envelope, maintained irregularly, or loaded with something it was never sized for. Our work spans both: engineering the right system for the site, and keeping it working afterwards.

Sewage treatment plant design and implementation

Sewage treatment plants designed around the actual flow and load a site generates, including the variation across a day and across a season. Hotels, residential communities and institutional buildings have very different loading profiles from industry, and a plant sized on a per-head figure alone is the most common reason a commissioned STP fails to hold its outlet standard.

Wastewater treatment and reactor design

Process selection and reactor design matched to the effluent's actual characteristics — strength, biodegradability, variability and the standard the discharge has to meet. We size the reactor from characterisation data rather than from a comparable facility, because the loading profile is rarely comparable in the ways that matter.

Solid waste treatment facilities and waste management

Practical handling, segregation, treatment and disposal arrangements for solid and liquid waste streams, including the treatment facility itself where one is required. We start from what the site actually generates and where it goes today, because waste plans built on assumed streams fail at the first audit.

Swimming pool and recreational water treatment

Treatment, circulation and water quality management for swimming pools and recreational water bodies in resorts, hotels, commercial facilities and residential communities. Balancing turnover, disinfection and testing frequency keeps quality consistent rather than corrected reactively after a complaint.

Water quality analysis, testing and reporting

Characterisation of water quality against the standard relevant to its use, followed by treatment support where the water does not meet it. Parameter selection is driven by intended use — drinking, process, discharge, irrigation and recreational water each impose different requirements, and testing everything is rarely the efficient route to an answer.

Pollution control and system operation and maintenance

Control measures matched to the site's real characteristics, plus ongoing operation and maintenance support for installed treatment and control systems: performance monitoring, corrective action, and the record keeping that demonstrates the system is doing what it was permitted to do.

Rainwater harvesting planning and guidance

Assessment of catchment area, rainfall pattern and demand to size storage and recharge realistically. Harvesting systems commonly underperform because storage was sized without reference to the demand profile, or because recharge potential at the site was assumed rather than assessed.

CADD and technical design

Drawings and technical design output for treatment works and environmental installations — layouts, unit details and schematics prepared to the standard a contractor can build from and an authority can review, rather than indicative sketches that have to be redrawn before construction.

Common questions

How is the size of a sewage treatment plant decided?

From the actual hydraulic and organic load the site will generate, including peak and seasonal variation, and from the outlet standard the treated effluent has to meet. A per-head estimate is a starting point, not a design basis — occupancy patterns in hotels and residential communities in particular differ enough to change the result substantially.

Our treatment system was compliant at commissioning but is failing now. Why?

Most commonly the load has changed — in volume, composition or variability — beyond what the system was sized for, or maintenance has drifted. Assessing actual current loading against the original design assumptions usually identifies the cause faster than modifying the system.

How large should a rainwater harvesting system be?

It depends on catchment area, local rainfall pattern and, critically, the demand it is intended to meet. Sizing storage without reference to the demand profile is the most frequent reason harvesting systems underperform.

Do you support residential communities and hotels as well as industry?

Yes. Hotels, resorts, commercial establishments and residential communities are among the sectors we work with most, and water quality, swimming pool treatment, sewage treatment and waste management are the areas they most often need support in.

Have a site or a deadline in mind?

Describe what you are dealing with and we will tell you what it needs, what it involves and roughly how long it takes. No obligation either way.
