Regulatory Reference
Common thresholds used during routine self-checks. These figures reference the UK Water Supply (Water Quality) Regulations as administered by the Drinking Water Inspectorate (DWI). Always verify against the latest official guidance.
pH range
Typical operational target 6.5 – 9.5. Most distribution systems sit between 7.0 and 8.0 at the customer tap.
Turbidity
≤ 1 NTU at the treatment works outlet, ≤ 4 NTU at the consumer point under normal operating conditions.
Free chlorine residual
Typical distribution target 0.2 – 0.5 mg/L. The dose calculator above defaults to 0.5 mg/L as a routine working target.
Total coliforms / E.coli
0 colony forming units per 100 mL. A single detection triggers immediate investigation under the regulations.
Temperature
Drinking water leaving the works typically sits in the 4 – 15 °C band depending on season and source.

Frequently asked questions
Common questions about how the tools work and what data they handle.
Does the app or this site collect any personal data?
No. The tools are offline calculators and a local log. Inputs and saved entries live in this browser, or on the device for the mobile app. Nothing is uploaded to MSCOMPLIANCE LTD.
Does the app need network access?
The Android app requests the INTERNET permission solely so the in-app links to the privacy policy and the company email can open. No data is sent from the calculators or the log.
Are the regulatory thresholds authoritative?
No. They are reference values to support routine self-checks. Operators must consult the current DWI guidance and the Water Supply (Water Quality) Regulations directly before acting on any reading.
Why is there no account?
The tools are meant for shift use on a single device. Removing the account avoids any handling of operator personal data and keeps the app fully offline.
Can I export saved entries?
Saved entries can be copied from the on-screen list. A CSV export will be considered for a future release if operators ask for it.
Who runs the company?
MSCOMPLIANCE LTD is a UK private limited company, Companies House number 13930988, registered at 174 Hope Farm Road, Great Sutton, Ellesmere Port, CH66 2NR. Product engineering is led by DR STOYAN SLAVOV.
