For developers

In densely developed areas, stormwater quickly becomes not only a design challenge, but also a formal and operational one. It is necessary to reconcile discharge restrictions, biologically active area requirements, protection of neighbouring plots, building safety, and the overall economics of the development.

In many locations, developers are not granted permission for unrestricted stormwater discharge into the sewer system, or they must comply with very strict discharge conditions. This means that rainwater must be managed on site in a way that is properly calculated, safe, and aligned with the requirements of the project. That is why, already at the concept stage, we design systems that do more than simply protect the site against local flooding. Our goal is not only to drain water away, but to organise the entire stormwater issue so that it does not return as a problem during approvals, construction, or the later use of the development.

Blue-Green Infrastructure as added value for developers

Our approach is both technical and environmentally responsible. We ensure that stormwater solutions incorporate blue-green infrastructure and reflect the standards of modern development. The rain gardens, retention basins, green roofs, biologically active surfaces, and local stormwater management systems we design are not just optional extras — they create real value for residents. Water is retained closer to where it falls, the site gains more greenery, the microclimate and quality of shared spaces improve, and the development simply becomes a better place to live.

We support developers not only at the concept and design stage, but also in the formal approval process. We prepare water law documentation and all materials required to obtain permits, ensuring that technical solutions are consistent with administrative requirements from the outset. As a result, the investor receives not only a drainage design, but comprehensive support in organising the entire stormwater scope – from risk analysis, through solution selection, to the formal preparation of the project for implementation.

What developers gain

• reduced risk of local flooding, dampness, runoff onto neighbouring plots, and design errors that lead to complaints and additional post-construction costs,
• better use of the site’s development potential and lower risk of late-stage design changes,
• greater predictability of the investment process.

We support both new developments and already advanced projects that require verification, correction, or an independent review of the adopted assumptions.

How we work

We begin with an analysis of the site, the development programme, and the stormwater discharge conditions. We then propose a drainage, retention, and blue-green infrastructure concept tailored to the character of the project and without limiting the investment’s development potential. Where necessary, we verify the adopted solutions using modelling and organise the documentation for further approvals.

Who it is for

For developers delivering residential estates, multi-family housing, commercial developments, hotels, mixed-use projects, and investors who want to properly assess retention, drainage, and water-related risk from the very beginning.

Are you planning a residential development, hotel, or commercial project? We will analyse the discharge conditions, select suitable retention solutions, and prepare your investment for safe implementation. Our in-house expert in this field is Renata.
