    Seaton Sea Outfall. No complaints were received at any time during the year in respect of the sewers or the sea outfall at Seaton, and the system functioned normally. One sewage sample was taken at Seaton, the result being as follows :—- Sewage Sample. Deposit consists entirely of vegetable debris and primitive animal and vegetable life, and decaying vegetation. No faecal contamination. Polperro Sea Outfall. In January 1961 a second storm water overflow was fitted to the main sewer in the harbour adjacent to Warren House. This provided an additional outlet at a point where, in the past, a certain amount of trouble had been experienced with flooding. Later in the year an examination of the sewer and branches from Saxon Bridge to Crumplehorne was made in order to find any point at which river water could enter the sewer and overload it. Several such points were found, including a partly plugged connection, and these were sealed off without delay. In March a sewer branch under the floor of the Shell House was exposed and it was found that several feet consisted merely of a culvert cut in the solid rock. This was replaced by cast-iron pipes encased in concrete and the work was completed satisfactorily. Towards the end of the year, a branch sewer across the harbour was cleared of obstruction after several hours of difficult work. On September 26th there was an 18' 0 tide and an opportunity was taken to cleanse the outfall tunnel. This was duly carried out and at the same time, an accumula¬ tion of pebbles and small boulders was removed from the final manhole beyond the tunnel. Polruan Sea Outfall. This system gave rise to no concern during 1961 and the only repair was to a joint in the 12 cast-iron sewer on the beach. St. Cleer Treatment Works. No problems were experienced with this system, and the usual twice weekly attention to the works was carried out. The glass roof over the drying beds enabled the sludge to be dried out rapidly, and it was able to be handled without difficulty. East Taphouse. This village is only partially sewered and no treatment is given to the effluent at the sewer outfall. The Council has placed this village high on the list for a system of sewers, and treatment works, and a scheme will be prepared during 1962. DobwaiSs. Treatment Works. This system has two pumping stations each with sewage ejectors in duplicate. These gave no trouble throughout the year. The treatment works were well maintained and the dried sludge was disposed of locally. As at Lanreath and Duloe it was decided to install a permanent sludge pump at the works in order to make for more easy main¬ tenance and the contract was well in hand by the end of the year. Other Villages. In accordance with the Council’s policy, sewerage schemes have been prepared for the large village of Pensilva, and the smaller ones of Common Moor, Crows Nest and Minions. In December a tender of £76,140. 19s. 4d. was accepted from Messrs. W. Carline Ltd., for the Pensilva Sewerage and Sewage Disposal Works. The work was scheduled to commence in January, 1962.
