How Cleantech Civils Added Value
The main gravity sewer pipe to the pump station was constructed across very poor ground conditions. The solution required a floating type design for the pipes and included one river crossing requiring fluming and over pumping. The storage and pump tank required breaking out large volumes of limestone rock in a flooded area with proximity to the local river. The Cleantech Civils team mitigated and managed all environmental risks.
Our team’s expertise guaranteed the successful delivery of this project. We managed our works in a busy site location – with simultaneous construction being at the nearby Killala Business Park. The project was successfully delivered on time, within the budget, and with a strong focus on collaboration with the ESB.
