Client: | Irish Water |
Main Contractor, PSCS & PSDP: | Cleantech Civils |
Location: | Gort, Co. Galway |
On this particular project, we were tasked with carrying out the works to a storage tank, designed to provide 24/7 treated water storage to some 3,000+ people in the Gort Water Supply Zone. Our proposal stipulated that the tank would be supplied from the Water Treatment Plant’s (WTP’s) existing clean water tank, via underground pipework, with the flow pumped directly from the new tank into the existing network.
Key Features of our Scope of Works
- A new partially buried treated water storage tank (18.1m x 17.6m) with a storage capacity of 1,500m3 with an overall height of 8m including:
- Concrete tank, connection pipework, scour and overflow pipework and a handrailing and access ladder built on land adjacent to the existing Gort WTP including pipework connections, scour and overflow and integration into the existing Water Supply Zone (WSZ).
- A new weather-proof enclosure (4m x 3m x 2.5m high) adjacent to the storage tank to house network pumps, relocated from Gort WTP, and local control panel.
- Installation of an emergency power generator, fuel storage and integral bund adjacent to the storage tank.
Ancillary development works, including:
- Associated ground works.
- Footpaths, vehicle turning area and hardstanding areas.
- Below-ground dechlorination chamber.
- Mechanical and electrical service connections.
- Extension of the existing 2.4m high security fencing at the WTP site to incorporate the storage tank and enclosures site.

How Cleantech Civils Added Value
Yet another Cleantech Civils plan that unfolded without a hitch. That’s not to say that the project didn’t have its fair share of challenges – primarily the constrained site area. There was only a narrow access point to the site and the existing road which was not fit for construction activities which compromised the required bulk material deliveries necessary for the project. The site’s close proximity with the existing Water Treatment Plant road further restricted our access due to the interface with the live environment of the existing substation. To ensure these potential challenges didn’t become problems, our highly qualified teams and project manager intricately planned all aspects of this project to ensure successfully its delivery.
The Cleantech Civils team liaised with the client to remove the option for an insitu reservoir and instead proposed a precast solution. We did this for two reasons, it meant that the precast reservoir could be delivered on site providing time and cost efficiencies, and this eliminated many variables that are associated with the mixing and pouring of cement on site, such as inclement weather which would affect the quality of the product with the insitu option. Secondly the precast option reduced the volume of personnel ‘Working from Height’ required for this project, as always safety is integral in all our works. The team developed a great relationship with the local school situated adjacent to the works site. As a result, and due to works area being extremely contained, they granted us permission to access our works via the school yard over the weekends, when students weren’t present, to ensure an unobstructed process without interruption to our programme. This was of great assistance for the crane that was utilised to deliver the precast concrete reservoir, and for bulk deliveries that could not be delivered via the narrow access point to the site.
