1 Business Energy Efficiency Seminar Theatre 21 May 2014 Sponsored by ABB Water cleaned for you and after you 4 Mosspark Avenue Milngavie Glasgow G62 8NL Bob Garrow Director R S Garrow Ltd Tel: E : Bob Garrow@rsgarrow.co.uk Web:

2 1 of 11 Bob Garrow set up R S Garrow Ltd to do Business and Product Development over twenty five years ago. seven and a half years as part of the team that set up and carried out Venture Capital investment at the Scottish Development Agency local government quoted company business development big five accountancy consulting electricity utility staff job after graduate apprenticeship with the biggest electrical engineer in the country

3 2 of 11 How come water services kit? Job interview as Development Manager at Assynt Foundation A shortage of housing sites in the Scottish Highlands!! Attributed to the high cost and difficulty in providing water services. Searched for answers qaward-winning drinking water processor lawful for use in Member States of the European Union qrange of package waste water treatment plants already operating in sensitive environments in the UK and around the world.

4 Energy Usage by Water Utilities 3 of 11 National Total Electricity Consumption Water Utilities Purposes of Energy Usage Water utilities Other uses Other users Moving water about Water utilities use 5% of all electricity Water utilities use >90% of the energy they consume for moving water around Water utilities use about 4.5% of National Electricity for moving water around

5 Sustainable Water 4 of 11 Destination of water metered in Consumed Comes out as waste water 95% of the water we take in comes out as waste water

6 Modular Waste Water Kit 5 of 11 Microbac submerged aerated fixed film biological treatment system package waste water plants aerobic bacteria do not smell 150m2 of biomass surface per m3 of volume sterile discharge water ü safe to re-use ü no dilution outfalls, soakaways, etc What do these features mean? Modules ü 20 people up ü no top limit little sewer infrastructure needed continuous process no process consumables ü no delivery logistics ü no consumable cost no sludge to ü cut performance ü remove ü treat elsewhere

7 6 of 11 After use clean Waste Water locally Select from Re-cycling for uses short of consumption q Hot water q Hygiene q Laundry q Toilets Re-use for other uses q Horticulture q Air conditioning q Vehicle washing Replace locally back in the natural water environment q Cleaner than the local natural water receiving it q Nature moves it on to its next natural or man made destination Effects of this q No waste water to be collected ü Heat recycled with water ü Water input volume = topping up 5% water routed for consumption q No waste water to be collected ü Leave nitrogen in water for this ü Can have already sterile water for this q 95% of water returned to nature ü No need to build or operate waste water collection ü Quality of environmental water improved by adding cleaner water

8 Modular Drinking Water Kit 7 of 11 Aqualogix activated carbon UF filter modular drinking water works What do these features mean? purifies non salt water sources drinking quality water q without removal of ü necessary life supporting minerals q with removal of ü dissolvable solids ü colloidal solids ü all virus colonies bacteria protozoa parasitic worms ü pesticides ü herbicides ü heavy metals (removed by pre-filter)

9 8 of 11 Collect natural water and clean locally for use Have options to collect and store rain water for later use to clean shipped in water locally before use drought contingency plan q reserve national store of pillow tanks q hire flatbed HGV s q truck or ship in water No need to Effects of this q build or operate water collection infrastructure q manage river catchment areas q build or operate clean water distribution network q chlorinate clean water No leakage loss of cleaned water in distribution network q may reduce flooding below pre-development levels ü mobilise national reserve to drought area ü standard commercial hire fleet vehicles ü reduced need for reservoirs

10 9 of 11 Energy Usage by Water Utilities Water utilities use 4.5% of National Electricity for moving water around If collecting natural water locally cleaning it locally for use cleaning our waste water locally after use returning it to nature locally or reusing it saves 2 / 3 of the energy we use for moving water around National Electricity use now and in future will drop by 3%

11 Sustainable Water Usage 95% of the water we take in comes out as waste water Commonly infrastructure sewers collect both rain water and sewage at historic sites where this then went straight into rivers or the sea 10 of 11 sewage works built there later now discharge various quality effluents through dilution and dispersal outfalls into rivers or the sea If instead we clean our waste water locally after use return it to nature locally or reuse it We may get 10 or 20 times more economic or domestic use from the same net volume of water extracted from the environment

12 11 of 11 Energy efficiency National Electricity use now and in future could drop by 3% Sustainability We might get 10 or 20 times more economic or domestic use from the same net volume of water extracted from the environment 4 Mosspark Avenue Bob Garrow Milngavie Director Glasgow G62 8NL R S Garrow Ltd Tel: E : Bob Garrow@rsgarrow.co.uk Water cleaned for you and after you Web:
