Treated water suitable for drinking is stored in service reservoirs. Not to be confused with raw water impounding reservoirs, service reservoirs need to be totally enclosed and protected from outside contamination by ground and surface water, animals, and vegetation. There are numerous treated water service reservoirs around the Island, ranging from small covered tanks storing only 22,730 litres up to large concrete structures holding 22.7 megalitres.
- provide a reserve of treated water to minimise possible supply interruptions due to pumping / treatment plant, or mains failure
- enable a fluctuating demand within the distribution system to be met
- provide stable and adequate mains pressure in the distribution network to minimise burst mains
We own 39 service reservoirs, 27 of which are currently operational.Need Help? Contact Us Water
