AGGRIEVED councillors from Wincanton, Castle Cary and Bruton gather next week to investigate how money generated from local developments is spent.
Wincanton Town Council called for support from other market town councils amid concerns that "section 106" money generated locally from new building could be spent in Yeovil.
The councils believe a greater proportion of money generated by local developments should be spent locally.
Representatives from the three town councils meet next Thursday to share their concerns.
Along with Langport Town Council, the three bodies want clarification from South Somerset District Council over how the money is being spent.
A section 106 agreement binds developers to paying towards community facilities including health and leisure centres.
Colin Winder, mayor of Wincanton, said: "Money has been collected from developers up and down the district and I want to know where it has gone.
"Wincanton, Castle Cary and Bruton town councils have had joint meetings before and we are trying to resurrect them.
"We need to move outside the box and work together.
"We want to know where money is going. Money that we think should be put towards providing sports facilities in our local area.
"It's a drain on ordinary working parents in our area to take their children to a county event every week.
"We need money to make sure sports facilities are available locally."
A district council spokesman said some areas of south Somerset had "insufficient need" to justify dedicated new facilities: "The challenge we face in planning to enhance strategic facility provision is that there's often insufficient need within an area itself to justify dedicated new provision for that specific area.
"We aim to ensure all residents have reasonable access to a range of high-quality open spaces and sport and recreation facilities," he added.
