Masterton District Council is expected to make a decision next week about whether or not to replace the compressors at Genesis Recreation Centre, at a cost of $400,000.
Council are investigating options to heat the indoor pools at the centre, according to a report in the ordinary meeting to be held tomorrow.
Council had major problems with the compressors last year after an electrical and a mechanical fault.
The faults with the pump were resolved and the pump ran without issue for three months, according to parks and facilities manager Grant Hathaway.
There was also a back-up diesel boiler installed to keep the pool warm in case the pump failed again.
