Improving Equine Health & Hydration: The Malta Water Quality Case Study by Balance EQ & Tappwater

Water is the most fundamental nutrient in an equine diet, yet it is often the most overlooked. While horse owners in Malta carefully weigh out forage, concentrate feeds, and targeted supplements, the quality and cleanliness of the water offered in the barn receives far less scrutiny. To evaluate whether targeted water filtration could measurably improve equine hydration and stable management under real-world Maltese conditions, Laura Wolsing—Founder & Equine Nutritionist at Balance EQ—collaborated with Tappwater Malta on a 15-day pilot study. Utilizing the Tappwater InlinePro SMR® under-sink and inline filtration system, this study monitored voluntary water intake, drinking behavior, and bucket hygiene across four participating horses. The findings demonstrate that clean, palatable water can significantly increase voluntary hydration while dramatically easing daily stable maintenance.

Key Takeaways

• Measurable Hydration Boost: All four test horses increased their voluntary daily water intake after the installation of the InlinePro SMR®, with intake spikes ranging from +11.0% to +18.8%.
• Behavioral Changes: Horses immediately approached refilled buckets, spending noticeably longer taking their initial drink—a behavior not recorded prior to filtration.
• Improved Bucket Hygiene: Biofilm (slimy bacterial build-up) was virtually eliminated, and algae growth was visibly reduced without requiring weekly scrub-downs.
• Uncompromising Water Flow: The system maintained a strong flow rate (8–10 L/min), enabling rapid bucket filling and easy integration upstream of standard hose taps or automatic drinking bowls.
• Exceptional Cost-Efficiency: At €59 per refill cartridge with a 20,000-liter capacity, the system provides clean, filtered water for a horse at maximum daily consumption for approximately €59 per year.

The Forgotten Nutrient: Why Water Quality Matters for Horses in Malta

An adult horse consumes between 20 to 60 liters of water every day depending on body weight, workload, diet, and ambient temperature. During Malta's long, humid summers, daily fluid requirements can surge even higher. However, providing clean, appealing water presents unique infrastructure challenges across local yards and private barns.

In Malta, stable water is commonly sourced from municipal tap supplies containing high chlorine levels, aged plumbing networks, or underground cisterns dependent on groundwater. Cistern systems are particularly susceptible to stagnant storage conditions, agricultural runoff, heavy rain sediments, and elevated microbial activity. Even when water appears visually clear and odorless to human senses, subtle chemical or biological impurities can deter a horse from drinking adequately.

Restricted voluntary water intake carries serious health implications for horses, including:

• Impaction Colic & Digestive Distress: Insufficient fluid intake prevents proper gut motility and food transit through the complex equine digestive tract.
• Dehydration & Heat Stress: High ambient temperatures combined with reduced drinking slow down natural thermoregulation and sweat recovery.
• Elevated Liver Enzymes & Systemic Stress: Chronic ingestion of contaminated or heavily mineralized stagnant water can cause persistent stress on internal organs, potentially contributing to anemia and reduced responsiveness to veterinary treatments.

Science Applied to Real-World Horses: The Work of Balance EQ

Balance EQ was founded by Laura Wolsing, an experienced Equine Nutritionist, on the principle that effective nutritional management requires viewing each horse as an individual. Rather than relying on generic feeding schedules, Laura constructs an evidence-based profile for every animal—factoring in age, breed, exercise discipline, body condition, metabolic status, forage quality, and environment.

Working in Malta highlighted a critical variable in equine management: water palatability and availability. Recognizing that even the most carefully balanced feed ration cannot function effectively if a horse is sub-optimally hydrated, Laura partnered with Tappwater Malta to test whether advanced inline filtration could overcome local water quality barriers.

The goal of this joint pilot project was simple yet rigorous: evaluate whether Tappwater’s InlinePro SMR® system could seamlessly integrate into an active Maltese barn routine and deliver measurable improvements in voluntary water consumption.

The Pilot Project Setup & The Role of the InlinePro SMR® Filter

The study took place over a 15-day monitoring period at a private barn in Malta supplied by an underground cistern system. To test the filtration unit under real-world management conditions, four horses of varying ages, breeds, and physiological profiles were selected:

Throughout the study, all management factors—including feed rations, hay types, turnout schedules, salt availability, and exercise routines—were kept strictly identical. The only change was the installation of the Tappwater InlinePro SMR® filter directly onto the tap supplying the hose line used to fill the horses' water buckets twice daily.

The Filtration System Selected

The InlinePro SMR® was selected for its compact form factor, continuous high flow rate (8–10 L/min), and advanced 5-stage filtration media:

1. Pre-Filter Mesh: Captures larger suspended solids, rust particles, and coarse sediment.
2. Carbon Mesh: Traps finer suspended matter to protect downstream filtration layers.
3. Activated Carbon Block: Absorbs chlorine, organochlorides, bad odors, and volatile organic compounds (VOCs).
4. Specialized Heavy Metal Media: Targeted reduction of heavy metals (lead, copper, nickel) commonly encountered in local plumbing.
5. Swedish Mineral Rock™ (SMR): Naturally remineralizes filtered water with balanced trace amounts of calcium, magnesium, and potassium—enhancing water taste and palatability without stripping vital minerals (unlike Reverse Osmosis).

Installation took under 10 minutes using standard hose fittings, requiring no permanent plumbing alterations—a major benefit for horse owners renting stable boxes across Malta.

Major Findings: What the Data & Daily Observations Revealed

The quantitative data collected over the 15-day period showed a consistent, positive shift in drinking volume across every participating horse immediately following the installation of the InlinePro SMR®.

1. Measurable Increase in Daily Water Intake

Each horse recorded an immediate rise in average daily water consumption:

• Valentina: Increased from 40.0 L/day to 47.5 L/day (+18.8%)
• Gabry: Increased from 48.0 L/day to 53.3 L/day (+11.0%)
• Rosie: Increased from 45.0 L/day to 52.1 L/day (+11.6%)
• Ami: Increased from 48.0 L/day to 55.5 L/day (+15.6%)

2. Immediate Behavioral Engagement

Stable observations revealed clear shifts in drinking behavior. Upon refilling buckets with filtered water, all four horses consistently approached their buckets immediately—frequently drinking while the hose was still running—and took noticeably longer initial drinks compared to baseline pre-filter observations.

3. Noticeable Reduction in Biofilm & Algae

Over the trial period, water buckets filled with filtered water maintained exceptional surface cleanliness. Biofilm—the slimy layer created by bacterial colonies on bucket walls—was virtually absent. Additionally, algae accumulation was significantly reduced. This indicates that removing organic impurities and chlorine by-products helps disrupt the food source for algae and bacterial growth, drastically reducing daily bucket scrubbing duties.

Our customers across Malta frequently highlight similar ease of installation and immediate taste improvements:

Fitting the apparatus can be easily done by a person who is willing to try a bit of DIY. Once it's in place, it's extremely easy to use. We have stopped buying bottled water because the filtering makes tap water taste pleasant. I noticed an improved taste even when using filtered water for tea or coffee. The team behind the product has proved to be extremely helpful.

Practical Value, Cost Breakdown & Personal Reflection

From a yard management perspective, implementing an inline filtration system must be both practical and financially viable.

Cost & Life-Cycle Analysis

The InlinePro SMR® replacement cartridge is priced at €59 and is rated to filter between 15,000 and 20,000 liters of water.

Even for a large horse drinking at maximum summer capacity (approx. 55 L/day), a single €59 cartridge provides a full year of continuous filtered water. For smaller setups or individual horse owners, this translates to less than 16 cents per day for clean, highly palatable water—delivering massive cost savings compared to purchasing tankered water or treating dehydration-related health issues.

Personal Perspective on the Pilot Study

Reflecting on the collaboration and study outcomes Phil Richards from Tappwater Malta said:

"I was very interested in seeing how the InlinePro worked in an equine environment and enjoyed seeing the success of the results and how the filter made a difference. Laura's expertise in this area really helped me realise how important water is to a horse's health and opened my eyes as to how the InlinePro could be used in this environment."

Furthermore, the system offers versatile deployment across different barn configurations:

• Direct Hose Attachment: Easily connects to standard garden hose fittings for filling buckets, soaking hay cobs, or mixing mash feeds.
• Automatic Drinker Integration: Can be fitted upstream on main supply pipes feeding individual automatic water bowls without restricting line pressure.

Frequently Asked Questions

1. Why is tap and cistern water quality a concern for horses in Malta?
   In Malta, drinking water originates from municipal mains with added chlorine or underground cisterns exposed to groundwater stagnation, sediments, and agricultural runoff. Suboptimal water taste or impurities can cause horses to drink less, increasing the risk of dehydration and impaction colic.
2. How much water does an adult horse need to drink every day?
   An adult horse typically consumes between 20 to 60 liters of water daily. Requirements increase during summer heat, heavy workload, or when feeding dry forage and concentrates.
3. What were the main findings of the Balance EQ case study with Tappwater?
   The 15-day pilot study in Malta showed an immediate increase in voluntary water consumption across all four test horses (+11.0% to +18.8%), longer initial drinking sessions, and a dramatic reduction in bucket biofilm and algae build-up.
