Scottish Borders Water Network Investment
Scottish Water are investing £30 million in the water network supplying Galashiels, Selkirk and the surrounding area.
The project will deliver improved treatment processes and a more resilient supply to over 20,000 households and businesses across several towns and villages including Selkirk, Galashiels, Melrose, Lauder, Fountainhall and Newton St Boswells. The project will also deliver environmental benefits.
This project is required for a number of reasons
- Manse Street Water Treatment Works has come to the end of its serviceable life;
- The Caddon Water has been identified by SEPA as being impacted by our abstractions and;
- We want to improve the resilience of the local network

New water treatment processes
We are changing the treatment processes at the Howden Water Treatment Works to enable it to supply the whole area.
Part of this involves adding new membrane filters. It will enable us to provide clearer, fresher water than ever before.
These filters will force over 14million litres a day through 0.4 micrometre wide straws - 25 times narrower than the thickness of cling film
This will not impact on the taste of your water.
We will be keeping customers updated throughout these changes.
New clear water tank
A Clear Water Tank stores water once it has been treated and monitors the quality before it goes into supply. It provides additional strength in the network by providing enough storage to supply the area if there any issues elsewhere in the network.
The new water storage tank is capable of holding nearly 5 Olympic sized swimming pools worth of water.
It will be sympathetically landscaped in to the hillside next to the A7 – with all excavated material being reused for landscaping.
