Scottish Water has, for statistics purposes, divided Scotland into 4 regions: North, South, East and West. Because the majority of the population live within the central belt (Edinburgh and Glasgow) and are spread between the South and East. Because of the greater density, Scottish Water got more "bang for it's buck" spending money there. In fact, when Scottish Water was first established, they estimated that it would cost twice as much to deliver good services in terms of water quality, water supply and disposal, flood control and waterway improvements to small towns and rural areas as over the urban areas. They have since admitted they got that very wrong.... it costs 60 times the amount to provide the same service to rural and towns as it does to the big cities because the densities are less and the networks for supplying are much greater.
That means that an upgraded water treatment system with a cost of £50,000,000 to service 300,000 households in Glasgow would cost £3,000,000,000 in rural Scotland to service the same number of houses because a larger number of water treatment plants would need to be upgraded to fix the supply to 300,000 households in small towns and rural communities.
That changed in 2017 when a winter storm quick froze water supply pipes and then rapidly thawed cause 15 major water supply pipe failures in the North and East of Scotland. BUT, because of the money put into the system in the East, there was only two failures there even though the storm had a greater impact there than in the North, where the infrastructure failed because of lack of investment compared to the East. Scottish Water has now pumped more money into the North to not just repair what was damaged but to improve the overall system. That's meant that now, North Scotland has an estimated water leakage from the supply system of 38% while West Scotland, with a comparable population and density but without the investment in the supply system, has a water leakage percentage of 53%.
More money spent has also led to better outcomes in terms of complaints to Scottish Water over the quality of the water supplied and this is also reflected in the testing results conducted by Scottish Water and reported to the Drinking Water Quality Regulator. Take a look at the report below and you'll find that the supply systems that reported issues were in lower population areas that received less funding. In fact, although again the density and population of West and North Scotland are similar, under investment in the infrastructure in West Scotland meant there was twice as many complaints there about water quality and twice as many failed tests than in North Scotland.
One of the ways Scottish Water plans on improving the water quality in the rivers and waterways is called the Improving Urban Waterways Roadmap. It is designed to eliminate throughout the entire country places where both waste and stormwater enter a river or waterway through a single pipe called a combined sewer overflows (CSOs) poluting that watercourse. The Roadmap has identified over 3,600 CSOs that will need to be removed. So far, 276 have had work commenced on them.... only one of those is located in West Scotland (in Mallaig, Highland) and none are in North Scotland. The other 275 are all located in the heavliy populated central belt. Again, this shows Scottish Water prioritising cities over rural and small towns.

But, most damning of all that Scottish Water continues to invest more in the major cities than in the rural and small towns is the screenshot below. It shows the number of projects which Scottish Water are currently investing in.... note the lack of investment in the less populated, but more expensive, areas.....
