Water Main Failure in a Municipality — The Head of Municipality's Obligations and Action Plan
A water network failure requires an immediate response from the municipality. Learn about the legal obligations, emergency procedures, and ways to ensure alternative water supply.
Water main failures by the numbers
Typical time to resolve a water main failure — from detection to restoration of water supply.
Estimated number of serious water main failures (cutting off supply to >100 people) recorded annually.
Typical cost of organising alternative water supply during a prolonged failure (tanker trucks, bottled water).
Average number of residents affected by a single serious water network failure in a municipality.
Legal obligations of the municipality in an emergency situation
The Act on Collective Water Supply and Collective Wastewater Disposal (Article 5, paragraph 1) clearly states that ensuring residents' access to drinking water is the municipality's own statutory task. This obligation does not cease in the event of a failure — on the contrary, an emergency situation activates additional procedures.
The head of municipality (mayor, city president), as the executive body of the municipality, is responsible for activating the crisis management plan with regard to water supply. This plan should include: procedures for notifying residents, a list of alternative water sources, contracts with tanker truck and bottled water suppliers, and the locations of water distribution points.
In accordance with the Crisis Management Act, the head of municipality is obliged to notify the District Crisis Management Centre without delay about the situation. For failures affecting more than 500 people for a period exceeding 12 hours, coordination procedures are activated at the district level.
Emergency response timeline
0–2 hours after failure detection: identification of the scope of the problem (how many people affected, estimated repair time), notification of technical services, activation of initial communications to residents (SMS, website, social media, loudspeakers in the field).
2–6 hours: if the failure is not resolved within 4 hours, it is necessary to activate alternative water supply — tanker trucks with drinking water at designated points, distribution of bottled water to priority facilities (hospitals, care homes, schools).
6–24 hours: deployment of a full alternative supply system, securing additional water resources (mobile tanks, contracts with neighbouring municipalities), updating communications to residents on repair progress and locations of water distribution points.
Over 24 hours: the situation qualifies as a prolonged crisis. The mayor should consider convening the municipal crisis management team, reporting the situation to the provincial governor, and activating strategic reserves. It becomes necessary to establish permanent water distribution points using stationary or mobile tanks.
Communication with residents
Effective crisis communication is not only a legal obligation, but also a condition for avoiding panic and chaos. The first notification should reach residents within 1–2 hours of the fault being detected and include: a description of the problem, the estimated repair time, recommendations (e.g. "do not use tap water for drinking"), and contact details for the municipal office.
Communication channels should be diversified: an SMS system for residents (requiring a pre-existing database of numbers), the municipal website and social media, local radio, notices on bulletin boards, and in critical situations — announcements via loudspeakers mounted on municipal service vehicles.
It is important to update information regularly — even when there is no new data on repair progress. A lack of communication breeds anxiety and generates hundreds of calls to the municipal office, placing additional strain on staff during a crisis. Publishing updates every 2–4 hours is recommended.
Alternative water supply — operational options
Water bowsers (drinking water tanker trucks) are the fastest immediate solution. A single tanker with a capacity of 10 m³ serves approximately 500–1,000 people per day (based on a standard of 10–15 litres per person per day). The drawback: the number of available bowsers is limited, and in the event of a fault affecting a large municipality, demand quickly exceeds capacity.
Mobile water tanks placed at designated distribution points resolve the issue of supply continuity. A 2,000–5,000 litre stainless-steel tank with PZH certification can be refilled on a cycle and made available to residents 24/7. This is a cheaper and more reliable solution than running bowsers on continuous rounds.
Bottled water is a supplement, not a primary solution. For 5,000 residents affected by a fault, daily demand is approximately 10,000–15,000 litres — that is 5,000–7,500 two-litre bottles. The costs and logistics of delivering such quantities are considerable.
The most effective strategy is a combination of methods: mobile tanks at fixed distribution points + bowsers to refill the tanks + bottled water for priority facilities. This system should be planned and tested before a fault occurs.
Prevention and preparedness — how to prepare the municipality?
The most effective way to minimise the impact of a fault is investment in preparedness. The municipality should have: an up-to-date crisis management plan with procedures for water supply failures, a contact list for bowser and water suppliers, framework agreements for emergency water supply, and — where possible — its own mobile water tanks.
Regular audits of the water supply network make it possible to identify sections with the highest failure risk (old pipes, critical junctions, areas with unstable ground). Preventive replacement of critical sections is many times less costly than managing a crisis after a failure has occurred.
It is also recommended to conduct drills on responding to a water supply failure every 1–2 years. Drills allow procedures to be tested, gaps to be identified, and staff to be trained. Many municipalities skip this step, which results in operational chaos when an actual failure occurs.
Investment in reserve water tanks on municipal premises (at treatment plants, water purification stations, or at strategic residential locations) provides a time buffer for initiating repair actions without an immediate water deficit for residents.
