BACKGROUND

▪ Sydney Water Pool Best Practice Guide

▪ Surveys & benchmarking study of >80 council pool

▪ Energy & water audits 20+ pools

▪ Cooling Tower monitoring - QIC, Mirvac, Garvan

▪ Legionella risk mitigation

▪ 3 year study & trials of IIoT technologies

▪ Consulting and management services

TODAY’S KEY MESSAGE

Most pool and CT systems have changed little over the last 20-30 years; most controllers still operate standalone so are data SILOS.

IIoT brings new technology that allows their cost effective integration and connection to the internet and other related systems. Costs can be reduced and overall system performance improved.

CLASSIC SILO 1PUMPS, FANS & VSDs

BUSINESS AS USUAL

▪ Pool pump operate 24x7 regardless of water quality

▪ 60% energy waste if pump or fan speed is 20% higher than needed

NEXT GENERATION IIoT

▪ Fit VSDs with demand-based control of pump and fan speed

▪ Reduced kWh energy use and maximum demand costs

▪ Extend pump, fan and motor life

▪ Increase water filtration efficacy

EXISTING IIoT GENERATION

CLASSIC SILO 2POOL & CT CHEMICAL DOSING

BUSINESS AS USUAL

▪ Controllers isolated silos, information not shared

▪ Status not reported, chemicals not measured

▪ Poor compliance reporting & risk management

NEXT GENERATION IIoT

▪ Controllers - remote real time monitoring & alarms

▪ Dosing Pumps – status & consumption reporting

▪ Interface – link to filter pumps, water testing machine & IIoT Platform

IIoT BENEFITS FOR POOLS & CTs

▪ REDUCED RUNNING AND MAINTENANCE COSTS

▪ IMPROVED WATER QUALITY, LESS SCALE & CORROSION

▪ REDUCED ECOLOGICAL FOOT PRINT

▪ IMPROVED QUALITY OF RECORD KEEPING & REPORTING

▪ REDUCED RISK OF WHS NON COMPLIANCE

▪ KPIs AND BENCHMARKING TO DRIVE IMPROVEMENTS

IIoT BARRIERS TO SUCCESS

1. LACK OF KNOWEDGE ABOUT IIoT

2. ABSENCE OF SMART CITY INVESTIATION OR PLANNING

3. LACK OF NECESSARY ICT AND TECHNOLGY SKILLS

4. LACK OF UNDERSTANDING IN HOW SYSTEMS WORK

5. OUTSOURCING TO LOWEST COST 3RD PARTIES

6. RATE OF CHANGE

TODAY’S KEY MESSAGE……

“Pool and CT plant rooms have multiple controllers and sensors that do not talk to each other let alone anybody else. IIoT technologies now make it possible for them to be interconnected and feed data to the internet. Real time analysis of this data provides directly useful information that allows timely action with cost savings plus improved and safer operations.”
