Water & Sewerage in Hightae
Hightae, Heck, Greenhill and Smallholm receive their drinking water from Scottish Water’s Black Esk regulation zone. Sewerage and wastewater charges are collected together with your Dumfries & Galloway Council Tax – there is no separate water bill like in England and Wales.
How you pay – Council Tax billing explained
In Scotland, water supply and wastewater (sewerage) charges are added directly to your Council Tax bill. Scottish Water is the only provider – there is no choice of supplier. Most homes in the Royal Four Towns are connected to the public mains; a few outlying properties use private septic tanks and should not be charged the wastewater portion.

Water Hardness History – Black Esk Zone
Hardness comes mainly from natural calcium and magnesium in the ground. Here’s how the Black Esk zone has measured up over the last nine years (2025 hardness data not yet published):
| Year | Hardness (mg/l as CaCO₃) | Level |
|---|---|---|
| 2024 | 68.67 | Moderately Soft |
| 2023 | 69.98 | Moderately Soft |
| 2022 | 78.01 | Moderately Soft |
| 2021 | 85.26 | Moderately Soft |
| 2020 | 68.89 | Moderately Soft |
| 2019 | 77.29 | Moderately Soft |
| 2018 | 70.35 | Moderately Soft |
| 2017 | 84.15 | Moderately Soft |
| 2016 | 83.27 | Moderately Soft |
The water here has stayed consistently Moderately Soft for years. That means less limescale in your kettle, easier washing and it’s generally kinder on skin and appliances.
The Scottish Water site at the end of the village
You’ll have seen the fenced Scottish Water compound if you’ve walked or driven right to the end of Hightae. That’s the local wastewater pumping station – it collects sewage from the village and pumps it on for treatment. The clean drinking water comes from a different place: Black Esk Water Treatment Works at Boreland, a short distance away. That’s what supplies the taps in Hightae and the surrounding Royal Four Towns.
Sewerage – Mains or Septic Tank?
Most homes in Hightae village and the immediate Royal Four Towns are connected to the public sewerage network and pay the full wastewater charge. Some properties on the edge of the villages or in more rural parts use private septic tanks or sewage treatment plants. If your home is not connected to the public sewer you should not be charged the wastewater part of the bill – contact Scottish Water or your council to have this removed.
Septic Tank Emptying & Maintenance
Scottish Water offers a septic tank emptying service for properties that are not on the mains sewer. Local private companies also operate in Dumfries & Galloway and can often respond faster for urgent jobs. Popular local providers include:
- WC in Fields – reliable emptying throughout south-west Scotland
- RA Dalton Ltd – specialists in septic tank installation, repair and emptying
- Southwest Drainage Solutions – covers Lockerbie, Annan and surrounding areas
