Top Summer Water Tank Maintenance Tips

Published: June 3, 2026

Summer brings warmer temperatures, increased water usage, and additional challenges for commercial water storage systems. Without regular maintenance, higher temperatures can increase the risk of bacterial growth, water quality issues, and accelerated wear on tank components. Here are some essential summer water tank maintenance tips to help keep your system operating safely and efficiently.

1. Schedule a Water Tank Inspection

Summer is an ideal time to inspect your water tank for signs of:

Corrosion
Damaged coatings or liners
Cracks and leaks
Loose fittings

Identifying issues early can prevent costly repairs and unexpected downtime later in the year. Get in touch with ES Water Solutions to schedule your tank inspection.

2. Check for Signs of Biological Growth

Warmer conditions can encourage the growth of bacteria, algae, and biofilm inside water tanks.

Look out for:

Unusual odours
Discoloured water
Slime or residue on internal surfaces

Routine cleaning and inspections can help maintain water quality and compliance.

3. Assess Your Tank Lining Condition

The summer months are a good opportunity to assess the condition of existing tank liners.

A damaged or ageing liner may lead to:

Corrosion beneath the lining
Reduced water quality
Increased maintenance costs

If deterioration is identified, tank relining can often provide a cost-effective alternative to full tank replacement.

4. Inspect Tank Lids, Vents and Screens

External components play a crucial role in protecting stored water.

Ensure:

Access covers are secure
Ventilation screens are intact
No insects or debris can enter the tank

This simple check can significantly reduce contamination risks.

5. Monitor Water Temperatures

Higher ambient temperatures can impact stored water quality.

Facilities managers should:

Monitor temperature trends
Ensure insulation remains effective
Address any issues that may contribute to excessive temperature increases

Maintaining suitable temperatures helps reduce the risk of bacterial growth.

6. Review Maintenance Records

Summer is often a good time to review previous inspection reports and maintenance schedules.

Check:

When the tank was last cleaned
Previous repair recommendations
Inspection frequencies
Compliance requirements

A proactive approach can help avoid emergency repairs during peak operational periods.

7. Plan Ahead for Autumn and Winter

While focusing on summer maintenance, it’s also worth preparing for the colder months ahead.

Consider:

Any recommended repairs
Relining requirements
Cleaning schedules
Future inspections

Addressing issues during summer often provides greater flexibility and reduces the likelihood of weather-related delays later in the year.

Regular summer maintenance can help protect water quality, extend the lifespan of your tank, and reduce the likelihood of costly repairs. By carrying out inspections, monitoring tank conditions, and addressing issues early, building owners and facilities managers can ensure their water storage systems remain reliable throughout the year.

We manage a large residential block and recently reached out to Echo to quote to reline two water tanks that were failing. An absolute fantastic service all round. A quote was received within a day or so. Works were booked in and communication was excellent. We were really impressed with the engineers on the day. They communicated well on the day in terms of the plan of action. Once the work was complete, they ensured all areas were left clean and tidy. A follow up report post works was sent very soon after the works.

We look forward to working with Echo again. If you need honest, reliable contractors who will get the job done and to a high a standard, don't hesitate to get in touch with them.

Thank you.

I contacted Echo Square on behalf of a client of mine who urgently needed her Victorian underground Cistern re lined. The work was quoted for promptly and the work carried out to a high standard by the engineers who were courteous and friendly despite their long drive to site. My client was very impressed and so grateful to have her Cistern back in working order. I would highly recommend this company and will most definitely approach them again should I have another client with tank issues in the future. 5 star service!

Echo Square Services team assisted in helping with the refurbishment of two very difficult to access steel water tanks located at a VIP client’s head office.

Their team did a fantastic job.

I was especially impressed by the comprehensive photo report at the end.

Highly recommend!

Having used other companies in the past I can wholeheartedly say that our dealings with Nationwide Tank Relining have been a breath of fresh air. We have had tanks relined, water hygiene assessments and floor coatings. All work was carried out in a timely manner and the quality of work has each and every time been exemplary. My bosses are thrilled with my decision to switch to Nationwide Tank Relining and a tank that was relined 10 years ago by them still looks good as new internally, and the money we've saved from choosing the right supplier has proven to be a very smart business move. Highly recommended!
