Water – The Green Tau

Counting on 2026 …. Day 49

Caring for water is to be mindful of what goes down the drain. Waste water systems – drains, sewers etc – are not intended as general rubbish bins!

They are not places for alien chemicals. Using only eco friendly laundry and washing up liquids makes sense. Nor are they places for wet wipes, paper towels or paper serviettes – these are design to be strong and absorbent and doing that means they likely block the drain!

They are not places for oil and grease – wipe excess oil from pans etc using a paper and put that in your compost heap or food bin. Nor are they the place for paints, white spirit, varnish etc. Your local authority should have disposal facilities for these.

Drains are also not the place for waste food – this should go in your compost heap or food bin (the latter only should be used for items like meat, fish etc).

As part of being resilient, we aim to keep at least three days’ supply of food and water in the house.

Green Tau Issue 121

As part of these emergency supplies, I am loath to buy bottles of water which I would then have to replace when they reached their expired date – it would be expensive and would produce unnecessary waste. So instead we keep next to the sink a mixture of 1 litre kilner bottles and 4.5 litre Demi johns. These we use and refill on rotation (the bottles are numbered) to fill the kettle, make drinks, cook with and wash up etc. The water in the bottles is thus seldom more than 24 hours old – and in this hot weather, we keep a couple of bottles in the fridge too.

Water is a scarce and valuable resource that we need to protect and use respectfully and frugally.

That is why I shower and wash my hair once a week. The rest of the week I wash in a bowl of water – and then reuse that water for flushing the toilet. I’m sure I’m still clean and fresh smelling!

We only use the toilet flush for ‘number twos’ and use hand wash water (having used a bowl) to flush the toilet.

For toilet cleaning I use hot water and citric acid followed by a dose of bicarbonate – the following burst of bubbles is very dramatic. In this way I hope to reduce the adverse chemicals entering the drains as well as using cleaning materials that come in paper packaging.

Rivers of Spirit: Spirit of Rivers – a reflection

On the last day of the festival, the great day, while Jesus was standing there, he cried out, “Let anyone who is thirsty come to me, and let the one who believes in me drink. As the scripture has said, ‘Out of the believer’s heart shall flow rivers of living water.’” Now he said this about the Spirit, which believers in him were to receive; for as yet there was no Spirit, because Jesus was not yet glorified. John 7:37-39

The above is one of the alternative readings given for Pentecost which thinks of the Spirit not as wind or fire, but as a river of water.

Last Friday I took part in a thought-provoking event at St John’s Waterloo entitled Rivers of Spirit: Spirit of Rivers – https://stjohnswaterloo.org/tag/rivers-of-life/

We began by going down on to the foreshore of the Thames where, like children, we looked at all the treasures on the little beach – shells and pebbles, smooth-worn glass, ends of clay pipes, rounded stubs of brick, sticks and pieces of bone. We sang and we prayed as, with increasing reverence, we were drawn to the sound and the movement of the river, to the ebbing-flowing tide – drawn to the Thames living presence.

From that reconnection with the river, we were more open to hear the wisdom of the afternoon’s speakers.

Bishop Martin himself quoted from the passage from John’s Gospel, and talked about the living nature of water through the example of the eel.

Eels are amazing creatures. They are laid as eggs in the Sargasso Sea from where they voyage by ocean currents some 6500km to reach Europe. During this first couple of years they develop from egg to glass eel. They leave the sea and swim inland up various rivers including the Thames, where they continue to develop becoming elvers and then yellow eels and finally silver eels – this can span from 5 to 20 years. Now they are mature enough to make the return journey to the Sargasso to begin the whole cycle again. Eels in the past were numerous in our rivers and a source of food for many (and not just humans). But due to the effects of climate change, pollution, loss of habitat including from obstacles such as weirs and dams, their numbers over the last 40 years have declined by a staggering 95-98%. (1)

God’s Spirit, like rivers of living water, is there to cleanse and refresh us. But what if we harden our hearts and do not seek forgiveness and renewal?

The first two speakers, Al Barrett and John White spoke about the importance of creating communities. Al Barrett is the vicar of the Hodge Hill Church in east Birmingham. John White is the founder of the Hazelnut Community and author of the Rooted in Rubble articles from which I have recently quoted.

Al spoke about creating ‘bumping places’ – places where parishioners from many and diverse backgrounds can meet and get to know and trust each other. He spoke how during Covid they ‘rediscovered’ the green places in the parish including the common. Commons have existed for hundreds of years as spaces designated for use by the community – the commoners – who would have rights to graze animals, gather firewood etc. Where Commons remain today they are often important as essential green spaces for local people and as essential habitats for wildlife.

And Al described how finally he managed to ‘discover’ the River Tame which was barricaded out of sight and inaccessible to the community through which it flowed.

John spoke about how the Hazelnut Community’s garden brings people together in the garden and in the gardening. Gardens root us and place us in a right relationship with creation.

Debbie Colvin described to us our place – our home – within the Thames basin which stretches from the Cotswolds to the estuary, from the Chilterns and northwards to the South Downs. Within this area rainwater drains down to the Thames, but not just via stream and rivers, but also percolating down into the strata deep below our feet where the water moves and buffers, hydrating the ground, feeding into springs and wells. A slow and measured process whereby rain falling on the hills of Reigate may take 10-20,000 years before reaching Trafalgar Square. (Prior to the 1930s the fountains in Trafalgar Square were fed by artesian wells (2)).

Paul Powlesland spoke about his life’s journey that finds him as a self appointed river guardian for the River Roding and as the founder of the River Roding Trust. His love and respect of this river sees him clearing rubbish, planting willow and Black Poplar saplings and defending the rights of the river and the communities that live nearby. Called to jury service, Paul made his oath not on a Bible but on the River Roding, making this river a sacred thing, a being worthy of worship. (3) Much of this river, the third longest in London, is degraded – desecrated – by sewage, rubbish and pollution. Paul’s approach is hands on and includes pressing the Thames Water Authority to do its job properly. (4)

Paul himself lives off grid on a narrow boat which means his life is intrinsically connected to that of the river and the environment. His awareness of the drought that we are currently facing, is measured by how much water remains in the rainwater that provides him with water.

What struck me about the issues raised by these speakers was –

how little value we, as society, place on water,
our lack of concern/ interest as to where our water comes from and
our lack of concern as to whether it will be there in sufficient quantity in the future (humankind is extracting fresh water at a faster rate than the rate at which natural processes allow for replenishment (5))
our lack of concern for the health and wellbeing of our rivers – and not just our rivers, but the springs and aquifers from which they come, and
our lack of concern for the other living communities that depend upon rivers and the river environment.

At the same time, the speakers brought to mind way we might change our relationship with rivers:

looking at / treating rivers as living needs and rights, and
as beings that give generously of themselves to our benefit, and further,
that maybe we should treat rivers as sacred –
and not just rivers, but all water. In the past wells were often considered as holy places so why not also taps and reservoirs today?

And from this came thoughts about what we might do as local communities and as churches.

Create a map that shows local rivers, streams and wells.
Arrange pilgrimages to walk along or between these
To spend time in prayer and celebration in these places, to wonder and to rejoice.
Work out – maybe add to the map – where our drinking water comes from, and where it goes when we have used it
Find about local riverine habitats and whether they are in good or declining health.
To engage with – or establish – means of safeguarding and caring for wellbeing of your local river/ stream etc – and allowing yourselves to benefit from its contribution to your wellbeing.
Identify our local water sources as sacred.
Arrange water blessings for local rivers, streams and wells and wells
Provide blessings for taps, drains and water butts
Encourage people to value water – to treat it as sacred and not as something to be consumed rashly or without consideration
Encourage people to think about being less wasteful in the use of water. At current levels of consumption, we are likely by 2055 to see a shortage of 5 billion litres per day (6)
Encourage people to be aware of water cycles – seasonal changes, periods of rainfall and periods of droughts, of tidal cycles where appropriate.
Encourage people to do even small scale gardening (cress seeds grown on blotting paper) to appreciate the importance of water in keeping plants – and therefore us too – alive.

Third Sunday of Lent

8th March 2026

Reflection with readings below

In the reading from Exodus, the people are up in arms that they don’t have enough fresh water to drink. Quite rightly so. They know how important water is. Without water they will not survive.

Do we know what is important for life – or do we get distracted by populist issues such as wifi speed, foreign travel, journey times between London and Manchester, how many asylum seekers are occupying cheap hotel rooms, or the availability of strawberries in January?

Equally do we get up in arms about what is truly important? Are we more concerned about the love-lives of pop stars or the fate of prisoners? The domestic arrangements of the royal family or the plight of steel workers in Wales? The most recent diatribe from Nigel Farage or waiting times in our local A and E?

Returning to the necessity of water, how many of us are aware that Tehran is about to run out of drinking water? How many of us are concerned about the amount of water needed to cool AI data centres here in the UK?

The UK already faces a projected daily water deficit of nearly 5 billion litres by 2050 – which doesn’t include what might be needed by as yet to be built data centres. Might we expect agriculture to take precedence over data processing?

Water shortages re not just a UK issue, but a global issue. Across the world we are collectively consuming fresh water faster than supplies can be replenished! How many of us are outraged at the amount of water needed to make a cheap t shirt – worn today and thrown away tomorrow? Or how many of us are outraged that so much water is used to grow crops for cattle to eat so that ever greater quantities of meat can be consumed?

If nothing else, maybe their time in the wilderness taught the Hebrews that they couldn’t just expect water to be readily available at the drop of a hat – or a stick! More precisely they would have learnt that their access to water was dependent on their understanding their relationship with God. They should expect to go through life – or through the wilderness – without engaging in a real and trusting relationship with God.

God, as creator, is the source of the wisdom we need to live sustainably, securely, happily within the limits of creation. We are not gods. We cannot make creation conform to our demands. We have to live within the limitations of the created world. We cannot consume more water than the world can supply. We cannot discharge more pollution than the environment can absorb. We cannot take more resources from the earth than the earth can sustain.

Where are our contemporary prophets, who, like Moses, will challenge us to think rationally, who will challenge us to understand our dependency on God? Where are the preachers, the thinkers and writers, who will help us understand how God wishes to – and indeed does – relate with us, and the rest of creation? Are we ready to ‘kneel before the Lord our maker and listen to his voice’?

We can, nevertheless, draw consolation from the fact that God does not require us to be sinless for God to love us. What ever the state of our stupidity, our greed, our misplaced self-assurance, God is always willing to pay heed to our concerns, to afford us her wisdom, to show us a way forward. But we do have to want to engage with God – and that surely is what we mean by faith: the desire to be guided by God, to be in a relationship with God, to trust that God does indeed have answers to our problems. That is faith.

The Samaritan woman had the means of taking water out of the well. She could do this day in, day out – for as long as there was water in the well. What she hadn’t understood was that water like everything else was a gift that God had given her so that she might understand the universal nature of God, so that she might replicate God’s actions by sharing what was freely given so that all might benefit, that this water might enable eternal life not just for her and her tribe, but for everyone.

Like the Samaritan woman, we, even now in the 21st century, have a lot to learn about the life giving properties of water, and most particularly that those properties depend upon water being properly cherished and shared – to understand that all water is holy.

Exodus 17:1-7

From the wilderness of Sin the whole congregation of the Israelites journeyed by stages, as the Lord commanded. They camped at Rephidim, but there was no water for the people to drink. The people quarrelled with Moses, and said, “Give us water to drink.” Moses said to them, “Why do you quarrel with me? Why do you test the Lord?” But the people thirsted there for water; and the people complained against Moses and said, “Why did you bring us out of Egypt, to kill us and our children and livestock with thirst?” So Moses cried out to the Lord, “What shall I do with this people? They are almost ready to stone me.” The Lord said to Moses, “Go on ahead of the people, and take some of the elders of Israel with you; take in your hand the staff with which you struck the Nile, and go. I will be standing there in front of you on the rock at Horeb. Strike the rock, and water will come out of it, so that the people may drink.” Moses did so, in the sight of the elders of Israel. He called the place Massah and Meribah, because the Israelites quarrelled and tested the Lord, saying, “Is the Lord among us or not?”

Psalm 95

1 Come, let us sing to the Lord; *
let us shout for joy to the Rock of our salvation.

2 Let us come before his presence with thanksgiving *
and raise a loud shout to him with psalms.

3 For the Lord is a great God, *
and a great King above all gods.

4 In his hand are the caverns of the earth, *
and the heights of the hills are his also.

5 The sea is his, for he made it, *
and his hands have moulded the dry land.

6 Come, let us bow down, and bend the knee, *
and kneel before the Lord our Maker.

7 For he is our God,
and we are the people of his pasture and the sheep of his hand. *
Oh, that today you would hearken to his voice!

8 Harden not your hearts,
as your forebears did in the wilderness, *
at Meribah, and on that day at Massah,
when they tempted me.

9 They put me to the test, *
though they had seen my works.

10 Forty years long I detested that generation and said, *
“This people are wayward in their hearts;
they do not know my ways.”

11 So I swore in my wrath, *
“They shall not enter into my rest.”

Romans 5:1-11

Since we are justified by faith, we have peace with God through our Lord Jesus Christ, through whom we have obtained access to this grace in which we stand; and we boast in our hope of sharing the glory of God. And not only that, but we also boast in our sufferings, knowing that suffering produces endurance, and endurance produces character, and character produces hope, and hope does not disappoint us, because God’s love has been poured into our hearts through the Holy Spirit that has been given to us.

For while we were still weak, at the right time Christ died for the ungodly. Indeed, rarely will anyone die for a righteous person– though perhaps for a good person someone might actually dare to die. But God proves his love for us in that while we still were sinners Christ died for us. Much more surely then, now that we have been justified by his blood, will we be saved through him from the wrath of God. For if while we were enemies, we were reconciled to God through the death of his Son, much more surely, having been reconciled, will we be saved by his life. But more than that, we even boast in God through our Lord Jesus Christ, through whom we have now received reconciliation.

John 4:5-42

Jesus came to a Samaritan city called Sychar, near the plot of ground that Jacob had given to his son Joseph. Jacob’s well was there, and Jesus, tired out by his journey, was sitting by the well. It was about noon.

A Samaritan woman came to draw water, and Jesus said to her, “Give me a drink.” (His disciples had gone to the city to buy food.) The Samaritan woman said to him, “How is it that you, a Jew, ask a drink of me, a woman of Samaria?” (Jews do not share things in common with Samaritans.) Jesus answered her, “If you knew the gift of God, and who it is that is saying to you, ‘Give me a drink,’ you would have asked him, and he would have given you living water.” The woman said to him, “Sir, you have no bucket, and the well is deep. Where do you get that living water? Are you greater than our ancestor Jacob, who gave us the well, and with his sons and his flocks drank from it?” Jesus said to her, “Everyone who drinks of this water will be thirsty again, but those who drink of the water that I will give them will never be thirsty. The water that I will give will become in them a spring of water gushing up to eternal life.” The woman said to him, “Sir, give me this water, so that I may never be thirsty or have to keep coming here to draw water.”

Jesus said to her, “Go, call your husband, and come back.” The woman answered him, “I have no husband.” Jesus said to her, “You are right in saying, ‘I have no husband’; for you have had five husbands, and the one you have now is not your husband. What you have said is true!” The woman said to him, “Sir, I see that you are a prophet. Our ancestors worshiped on this mountain, but you say that the place where people must worship is in Jerusalem.” Jesus said to her, “Woman, believe me, the hour is coming when you will worship the Father neither on this mountain nor in Jerusalem. You worship what you do not know; we worship what we know, for salvation is from the Jews. But the hour is coming, and is now here, when the true worshipers will worship the Father in spirit and truth, for the Father seeks such as these to worship him. God is spirit, and those who worship him must worship in spirit and truth.” The woman said to him, “I know that Messiah is coming” (who is called Christ). “When he comes, he will proclaim all things to us.” Jesus said to her, “I am he, the one who is speaking to you.”

Just then his disciples came. They were astonished that he was speaking with a woman, but no one said, “What do you want?” or, “Why are you speaking with her?” Then the woman left her water jar and went back to the city. She said to the people, “Come and see a man who told me everything I have ever done! He cannot be the Messiah, can he?” They left the city and were on their way to him.

Meanwhile the disciples were urging him, “Rabbi, eat something.” But he said to them, “I have food to eat that you do not know about.” So the disciples said to one another, “Surely no one has brought him something to eat?” Jesus said to them, “My food is to do the will of him who sent me and to complete his work. Do you not say, ‘Four months more, then comes the harvest’? But I tell you, look around you, and see how the fields are ripe for harvesting. The reaper is already receiving wages and is gathering fruit for eternal life, so that sower and reaper may rejoice together. For here the saying holds true, ‘One sows and another reaps.’ I sent you to reap that for which you did not labor. Others have laboured, and you have entered into their labour.”

Many Samaritans from that city believed in him because of the woman’s testimony, “He told me everything I have ever done.” So when the Samaritans came to him, they asked him to stay with them; and he stayed there two days. And many more believed because of his word. They said to the woman, “It is no longer because of what you said that we believe, for we have heard for ourselves, and we know that this is truly the Saviour of the world.”

The water of eternal life

17th January 2026

(Part of the underlying stress in Iran is a lack of water. Tehran and other cities are on the verge of ‘Day Zero’ – when there will literally be no water in the pipes. This is a result of climate change, over consumption and a failure to maintain traditional means of collecting and storing water).

Jesus said … “Indeed, the water I give them will become in them a spring of water welling up to eternal life.” John 4:14b

You Lord, are the source of all good things:

We praise you.

You call us to tend and care for your creation:

May we strive to do your will.

You have made us as brothers and sisters with all that lives:

May we live together in peace.

A reading Ezekiel 47:1-12

Now he brought me back to the entrance to the Temple. I saw water pouring out from under the Temple porch to the east (the Temple faced east). The water poured from the south side of the Temple, south of the altar. He then took me out through the north gate and led me around the outside to the gate complex on the east. The water was gushing from under the south front of the Temple. He walked to the east with a measuring tape and measured off fifteen hundred feet, leading me through water that was ankle-deep. He measured off another fifteen hundred feet, leading me through water that was knee-deep. He measured off another fifteen hundred feet, leading me through water waist-deep. He measured off another fifteen hundred feet. By now it was a river over my head, water to swim in, water no one could possibly walk through. He said, “Son of man, have you had a good look?”

Then he took me back to the riverbank. While sitting on the bank, I noticed a lot of trees on both sides of the river. He told me, “This water flows east, descends to the Arabah and then into the sea, the sea of stagnant waters. When it empties into those waters, the sea will become fresh. Wherever the river flows, life will flourish—great schools of fish—because the river is turning the salt sea into fresh water. Where the river flows, life abounds. Fishermen will stand shoulder to shoulder along the shore from En Gedi all the way north to En-eglaim, casting their nets. The sea will teem with fish of all kinds, like the fish of the Great Mediterranean.

“The swamps and marshes won’t become fresh. They’ll stay salty. But the river itself, on both banks, will grow fruit trees of all kinds. Their leaves won’t wither, the fruit won’t fail. Every month they’ll bear fresh fruit because the river from the Sanctuary flows to them. Their fruit will be for food and their leaves for healing.”

In the beginning

it was a mere drop of water,

a slight dampness on the ground:
