Suomen Jätevesisuunnittelu

Suomen Jätevesisuunnittelu (Avalon Nordic Oy) is a specialist consultancy focused on wastewater solutions for sparsely populated areas. Based in Ii, the company provides impartial wastewater system design for both new builds and renovations, covering single-family homes and holiday properties.

The service concept is built around simplicity: the company handles the legally required plans and obtains the necessary municipal permits on a turnkey basis. With over 10 years of experience and more than 2,000 completed plans, the firm—led by HVAC engineer Olli Ukonmaanaho—offers expert advice independent of equipment manufacturers.

Starting point and goal

The company needed a modern website to support its expert brand and serve as an effective customer acquisition channel. The aim was to build a WordPress site that presents services clearly and convincingly. The project’s most critical requirement was search visibility: the goal was to reach top search engine rankings in a competitive industry.

Implementation

Tapio Kauranen handled the website project’s planning, technical implementation, and optimization. As Finland’s leading SEO professional, his approach prioritized building the site entirely for search visibility without neglecting user experience.

The site was built on WordPress, with a content structure carefully designed to match the search queries of potential customers.

Key elements of the implementation included:

  • Technical implementation and design of the WordPress website
  • In-depth keyword research and content optimization
  • Technical search engine optimization (SEO)
  • Site speed optimization
  • Conversion-optimized structure to maximize contact inquiries

Outcome

With the new website, Suomen Jätevesisuunnittelu’s digital presence has risen to a market-leader level. The site now ranks on Google’s first page for key business terms such as “jätevesisuunnittelu”, “jätevesisuunnitelma” and “jätevesijärjestelmät”.

Organic visibility has brought the company a steady stream of customers and reduced its reliance on paid advertising. The site now serves both information-seekers and customers planning wastewater renovation projects across Finland effectively.
