Sewage Treatment Service

Our sewage and effluent treatment solutions focus on reliability, compliance, and environmental responsibility. Whether for residential complexes, hotels, institutions, or industries, we deliver constructed wetland systems that meet high standards of treatment efficiency without the cost and complexity of conventional plants.

Watwa’s Sewage Treatment Process

Our French Vertical Flow constructed wetland system treats wastewater the way nature does. Sewage passes through a bar screen chamber, wet well, and holding tank before entering the planted wetland unit, where root systems and natural microbial activity break down organic matter and remove pollutants — largely through gravity flow, with no dependence on heavy mechanical aeration. The treated water collects in a final tank, ready for reuse in irrigation, flushing, or vehicle washing.

wå-trädgård: An Environmentally Friendly, Sustainable Choice

wå-trädgård is Watwa Engineers’ constructed wetland system for sewage and effluent treatment — a nature-based alternative to conventional electro-mechanical plants such as SBR, MBR, and MBBR systems.

Because most configurations run on gravity flow rather than continuous mechanical aeration, our systems use significantly less energy, need far less operator skill, and carry a smaller carbon footprint — making them a strong fit for organizations working toward sustainability goals.

Advantage of Constructed Wetlands

At Watwa Engineers, we build wetland systems that are simple, reliable, and cost-effective over their full working life. Here’s how wå-trädgård compares to conventional treatment systems:

We take pride in building systems that are as easy on your operating budget as they are on the environment. Our French Vertical Flow constructed wetlands turn wastewater treatment into clean, reusable water — with the lowest possible dependency on manpower, energy, and downtime. This is what a sustainable, climate-friendly approach to sewage and effluent treatment looks like in practice.
